Overview
-
extends: [EventEmitter]
Page provides methods to interact with a single tab in a ‘Browser`, or an [extension background page](developer.chrome.com/extensions/background_pages) in Chromium. One `Browser` instance might have multiple `Page` instances.
This example creates a page, navigates it to a URL, and then saves a screenshot:
“‘python sync from playwright.sync_api import sync_playwright
def run(playwright):
webkit = playwright.webkit
browser = webkit.launch()
context = browser.new_context()
page = context.new_page()
page.goto("https://example.com")
page.screenshot(path="screenshot.png")
browser.close()
with sync_playwright() as playwright:
run(playwright)
“‘
The Page class emits various events (described below) which can be handled using any of Node’s native [‘EventEmitter`](nodejs.org/api/events.html#events_class_eventemitter) methods, such as `on`, `once` or `removeListener`.
This example logs a message for a single page ‘load` event:
“‘py page.once(“load”, lambda: print(“page loaded!”)) “`
To unsubscribe from events use the ‘removeListener` method:
“‘py def log_request(intercepted_request):
print("a request was made:", intercepted_request.url)
page.on(“request”, log_request) # sometime later… page.remove_listener(“request”, log_request) “‘

# File 'lib/playwright_api/page.rb', line 47 def accessibility # property wrap_impl(@impl.accessibility) end |
#add_init_script(path: nil, script: nil) ⇒ Object
Adds a script which would be evaluated in one of the following scenarios:
-
Whenever the page is navigated.
-
Whenever the child frame is attached or navigated. In this case, the script is evaluated in the context of the newly attached frame.
The script is evaluated after the document was created but before any of its scripts were run. This is useful to amend the JavaScript environment, e.g. to seed ‘Math.random`.
Usage
An example of overriding ‘Math.random` before the page loads:
“‘python sync # in your playwright script, assuming the preload.js file is in same directory page.add_init_script(path=“./preload.js”) “`
NOTE: The order of evaluation of multiple scripts installed via [‘method: BrowserContext.addInitScript`] and
- ‘method: Page.addInitScript`
-
is not defined.

#check(selector, force: nil, noWaitAfter: nil, position: nil, strict: nil, timeout: nil, trial: nil) ⇒ Object
This method checks an element matching ‘selector` by performing the following steps:
-
Find an element matching ‘selector`. If there is none, wait until a matching element is attached to the DOM.
-
Ensure that matched element is a checkbox or a radio input. If not, this method throws. If the element is already checked, this method returns immediately.
-
Wait for [actionability](../actionability.md) checks on the matched element, unless ‘force` option is set. If the element is detached during the checks, the whole action is retried.
-
Scroll the element into view if needed.
-
Use [‘property: Page.mouse`] to click in the center of the element.
-
Wait for initiated navigations to either succeed or fail, unless ‘noWaitAfter` option is set.
-
Ensure that the element is now checked. If not, this method throws.
When all steps combined have not finished during the specified ‘timeout`, this method throws a `TimeoutError`. Passing zero timeout disables this.

#dblclick(selector, button: nil, delay: nil, force: nil, modifiers: nil, noWaitAfter: nil, position: nil, strict: nil, timeout: nil, trial: nil) ⇒ Object
This method double clicks an element matching ‘selector` by performing the following steps:
-
Find an element matching ‘selector`. If there is none, wait until a matching element is attached to the DOM.
-
Wait for [actionability](../actionability.md) checks on the matched element, unless ‘force` option is set. If the element is detached during the checks, the whole action is retried.
-
Scroll the element into view if needed.
-
Use [‘property: Page.mouse`] to double click in the center of the element, or the specified `position`.
-
Wait for initiated navigations to either succeed or fail, unless ‘noWaitAfter` option is set. Note that if the first click of the `dblclick()` triggers a navigation event, this method will throw.
When all steps combined have not finished during the specified ‘timeout`, this method throws a `TimeoutError`. Passing zero timeout disables this.
NOTE: ‘page.dblclick()` dispatches two `click` events and a single `dblclick` event.

#dispatch_event(selector, type, eventInit: nil, strict: nil, timeout: nil) ⇒ Object
The snippet below dispatches the ‘click` event on the element. Regardless of the visibility state of the element, `click` is dispatched. This is equivalent to calling [element.click()](developer.mozilla.org/en-US/docs/Web/API/HTMLElement/click).
Usage
“‘python sync page.dispatch_event(“button#submit”, “click”) “`
Under the hood, it creates an instance of an event based on the given ‘type`, initializes it with `eventInit` properties and dispatches it on the element. Events are `composed`, `cancelable` and bubble by default.
Since ‘eventInit` is event-specific, please refer to the events documentation for the lists of initial properties:
-
[DragEvent](developer.mozilla.org/en-US/docs/Web/API/DragEvent/DragEvent)
-
[FocusEvent](developer.mozilla.org/en-US/docs/Web/API/FocusEvent/FocusEvent)
-
[KeyboardEvent](developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/KeyboardEvent)
-
[MouseEvent](developer.mozilla.org/en-US/docs/Web/API/MouseEvent/MouseEvent)
-
[PointerEvent](developer.mozilla.org/en-US/docs/Web/API/PointerEvent/PointerEvent)
-
[TouchEvent](developer.mozilla.org/en-US/docs/Web/API/TouchEvent/TouchEvent)
-
[Event](developer.mozilla.org/en-US/docs/Web/API/Event/Event)
You can also specify ‘JSHandle` as the property value if you want live objects to be passed into the event:
“‘python sync # note you can only create data_transfer in chromium and firefox data_transfer = page.evaluate_handle(“new DataTransfer()”) page.dispatch_event(“#source”, “dragstart”, { “dataTransfer”: data_transfer }) “`

“‘python sync page.drag_and_drop(“#source”, “#target”) # or specify exact positions relative to the top-left corners of the elements: page.drag_and_drop(
"#source",
"#target",
source_position={"x": 34, "y": 7},

#emulate_media(colorScheme: nil, forcedColors: nil, media: nil, reducedMotion: nil) ⇒ Object
This method changes the ‘CSS media type` through the `media` argument, and/or the `’prefers-colors-scheme’‘ media feature, using the `colorScheme` argument.
Usage
“‘python sync page.evaluate(“matchMedia(’screen’).matches”) # → True page.evaluate(“matchMedia(‘print’).matches”) # → False

#eval_on_selector(selector, expression, arg: nil, strict: nil) ⇒ Object
The method finds an element matching the specified selector within the page and passes it as a first argument to ‘expression`. If no elements match the selector, the method throws an error. Returns the value of `expression`.
If ‘expression` returns a [Promise], then [`method: Page.evalOnSelector`] would wait for the promise to resolve and return its value.
Usage
“‘python sync search_value = page.eval_on_selector(“#search”, “el => el.value”) preload_href = page.eval_on_selector(“link”, “el => el.href”) html = page.eval_on_selector(“.main-container”, “(e, suffix) => e.outer_html + suffix”, “hello”) “`

#eval_on_selector_all(selector, expression, arg: nil) ⇒ Object
The method finds all elements matching the specified selector within the page and passes an array of matched elements as a first argument to ‘expression`. Returns the result of `expression` invocation.
If ‘expression` returns a [Promise], then [`method: Page.evalOnSelectorAll`] would wait for the promise to resolve and return its value.
Usage
“‘python sync div_counts = page.eval_on_selector_all(“div”, “(divs, min) => divs.length >= min”, 10) “`
349 350 351 |
# File 'lib/playwright_api/page.rb', line 349 def eval_on_selector_all(selector, expression, arg: nil) wrap_impl(@impl.eval_on_selector_all(unwrap_impl(selector), unwrap_impl(expression), arg: unwrap_impl(arg))) end |
#evaluate(expression, arg: nil) ⇒ Object
Returns the value of the ‘expression` invocation.
If the function passed to the [‘method: Page.evaluate`] returns a [Promise], then [`method: Page.evaluate`] would wait for the promise to resolve and return its value.
If the function passed to the [‘method: Page.evaluate`] returns a non- value, then
- ‘method: Page.evaluate`
-
resolves to ‘undefined`. Playwright also supports transferring some
additional values that are not serializable by ‘JSON`: `-0`, `NaN`, `Infinity`, `-Infinity`.
Usage
Passing argument to ‘expression`:
“‘python sync result = page.evaluate(“([x, y]) => Promise.resolve(x * y)”, [7, 8]) print(result) # prints “56” “`
A string can also be passed in instead of a function:
“‘python sync print(page.evaluate(“1 + 2”)) # prints “3” x = 10 print(page.evaluate(f“1 + x”)) # prints “11” “`
‘ElementHandle` instances can be passed as an argument to the [`method: Page.evaluate`]:
“‘python sync body_handle = page.evaluate(“document.body”) html = page.evaluate(“([body, suffix]) => body.innerHTML + suffix”, [body_handle, “hello”]) body_handle.dispose() “`
387 388 389 |
# File 'lib/playwright_api/page.rb', line 387 def evaluate(expression, arg: nil) wrap_impl(@impl.evaluate(unwrap_impl(expression), arg: unwrap_impl(arg))) end |
#evaluate_handle(expression, arg: nil) ⇒ Object
Returns the value of the ‘expression` invocation as a `JSHandle`.
The only difference between [‘method: Page.evaluate`] and [`method: Page.evaluateHandle`] is that [`method: Page.evaluateHandle`] returns `JSHandle`.
If the function passed to the [‘method: Page.evaluateHandle`] returns a [Promise], then [`method: Page.evaluateHandle`] would wait for the promise to resolve and return its value.
Usage
“‘python sync a_window_handle = page.evaluate_handle(“Promise.resolve(window)”) a_window_handle # handle for the window object. “`
A string can also be passed in instead of a function:
“‘python sync a_handle = page.evaluate_handle(“document”) # handle for the “document” “`
‘JSHandle` instances can be passed as an argument to the [`method: Page.evaluateHandle`]:
“‘python sync a_handle = page.evaluate_handle(“document.body”) result_handle = page.evaluate_handle(“body => body.innerHTML”, a_handle) print(result_handle.json_value()) result_handle.dispose() “`

#expect_console_message(predicate: nil, timeout: nil, &block) ⇒ Object
Performs action and waits for a ‘ConsoleMessage` to be logged by in the page. If predicate is provided, it passes `ConsoleMessage` value into the `predicate` function and waits for `predicate(message)` to return a truthy value. Will throw an error if the page is closed before the [`event: Page.console`] event is fired.

#expect_download(predicate: nil, timeout: nil, &block) ⇒ Object
Performs action and waits for a new ‘Download`. If predicate is provided, it passes `Download` value into the `predicate` function and waits for `predicate(download)` to return a truthy value. Will throw an error if the page is closed before the download event is fired.
1398 1399 1400 |

#expect_event(event, predicate: nil, timeout: nil, &block) ⇒ Object
Waits for event to fire and passes its value into the predicate function. Returns when the predicate returns truthy value. Will throw an error if the page is closed before the event is fired. Returns the event data value.
Usage
“‘python sync with page.expect_event(“framenavigated”) as event_info:
page.get_by_role("button")
frame = event_info.value “‘
1413 1414 1415 |

#expect_file_chooser(predicate: nil, timeout: nil, &block) ⇒ Object
Performs action and waits for a new ‘FileChooser` to be created. If predicate is provided, it passes `FileChooser` value into the `predicate` function and waits for `predicate(fileChooser)` to return a truthy value. Will throw an error if the page is closed before the file chooser is opened.
1421 1422 1423 |
# File 'lib/playwright_api/page.rb', line 1421 def expect_file_chooser(predicate: nil, timeout: nil, &block) wrap_impl(@impl.expect_file_chooser(predicate: unwrap_impl(predicate), timeout: unwrap_impl(timeout), &wrap_block_call(block))) end |
#expect_navigation(timeout: nil, url: nil, waitUntil: nil, &block) ⇒ Object
Waits for the main frame navigation and returns the main resource response. In case of multiple redirects, the navigation will resolve with the response of the last redirect. In case of navigation to a different anchor or navigation due to History API usage, the navigation will resolve with ‘null`.
Usage
This resolves when the page navigates to a new URL or reloads. It is useful for when you run code which will indirectly cause the page to navigate. e.g. The click target has an ‘onclick` handler that triggers navigation from a `setTimeout`. Consider this example:
“‘python sync with page.expect_navigation():
# This action triggers the navigation after a timeout.
page.get_by_text("Navigate after timeout").click()
# Resolves after navigation has finished “‘
NOTE: Usage of the [History API](developer.mozilla.org/en-US/docs/Web/API/History_API) to change the URL is considered a navigation.

#expect_request(urlOrPredicate, timeout: nil, &block) ⇒ Object
Waits for the matching request and returns it. See [waiting for event](../events.md#waiting-for-event) for more details about events.
Usage
“‘python sync with page.expect_request(“example.com/resource”) as first:
page.get_by_text("trigger request").click()

#expose_binding(name, callback, handle: nil) ⇒ Object
The method adds a function called ‘name` on the `window` object of every frame in this page. When called, the function executes `callback` and returns a [Promise] which resolves to the return value of `callback`. If the `callback` returns a [Promise], it will be awaited.
The first argument of the ‘callback` function contains information about the caller: `{ browserContext: BrowserContext, page: Page, frame: Frame }`.
See [‘method: BrowserContext.exposeBinding`] for the context-wide version.
NOTE: Functions installed via [‘method: Page.exposeBinding`] survive navigations.
Usage
An example of exposing page URL to all frames in a page:
“‘python sync from playwright.sync_api import sync_playwright
def run(playwright):
webkit = playwright.webkit
browser = webkit.launch(headless=false)
context = browser.new_context()
page = context.new_page()

}
</script>
<button onclick="onClick()">Click me</button>
<div></div>
""")
page.click("button")
with sync_playwright() as playwright:

“‘
An example of passing an element handle:
“‘python sync def print(source, element):
print(element.text_content())
page.expose_binding(“clicked”, print, handle=true) page.set_content(“”“
<script>
document.addEventListener('click', event => window.clicked(event.target));

#expose_function(name, callback) ⇒ Object
The method adds a function called ‘name` on the `window` object of every frame in the page. When called, the function executes `callback` and returns a [Promise] which resolves to the return value of `callback`.
If the ‘callback` returns a [Promise], it will be awaited.
See [‘method: BrowserContext.exposeFunction`] for context-wide exposed function.
NOTE: Functions installed via [‘method: Page.exposeFunction`] survive navigations.
Usage
An example of adding a ‘sha256` function to the page:
“‘python sync import hashlib from playwright.sync_api import sync_playwright
def sha256(text):
m = hashlib.sha256()
m.update(bytes(text, "utf8"))
return m.hexdigest()

#fill(selector, value, force: nil, noWaitAfter: nil, strict: nil, timeout: nil) ⇒ Object
This method waits for an element matching ‘selector`, waits for [actionability](../actionability.md) checks, focuses the element, fills it and triggers an `input` event after filling. Note that you can pass an empty string to clear the input field.
If the target element is not an ‘<input>`, `<textarea>` or `[contenteditable]` element, this method throws an error. However, if the element is inside the `<label>` element that has an associated [control](developer.mozilla.org/en-US/docs/Web/API/HTMLLabelElement/control), the control will be filled instead.
To send fine-grained keyboard events, use [‘method: Page.type`].

#frame_locator(selector) ⇒ Object
When working with iframes, you can create a frame locator that will enter the iframe and allow selecting elements in that iframe.
Usage
Following snippet locates element with text “Submit” in the iframe with id ‘my-frame`, like `<iframe id=“my-frame”>`:
“‘python sync locator = page.frame_locator(“#my-iframe”).get_by_text(“Submit”) locator.click() “`

#get_by_alt_text(text, exact: nil) ⇒ Object
Allows locating elements by their alt text.
Usage
For example, this method will find the image by alt text “Playwright logo”:
“‘html <img alt=’Playwright logo’> “‘
“‘python sync page.get_by_alt_text(“Playwright logo”).click() “`
612 613 614 |

#get_by_label(text, exact: nil) ⇒ Object
Allows locating input elements by the text of the associated label.
Usage
For example, this method will find the input by label text “Password” in the following DOM:
“‘html <label for=“password-input”>Password:</label> <input id=“password-input”> “`
“‘python sync page.get_by_label(“Password”).fill(“secret”) “`

#get_by_placeholder(text, exact: nil) ⇒ Object
Allows locating input elements by the placeholder text.
Usage
For example, consider the following DOM structure.
“‘html <input type=“email” placeholder=“[email protected]” /> “`
You can fill the input after locating it by the placeholder text:
“‘python sync page.get_by_placeholder(“[email protected]”).fill(“[email protected]”) “`
651 652 653 |
# File 'lib/playwright_api/page.rb', line 651 def get_by_placeholder(text, exact: nil) wrap_impl(@impl.get_by_placeholder(unwrap_impl(text), exact: unwrap_impl(exact))) end |
#get_by_role(role, checked: nil, disabled: nil, exact: nil, expanded: nil, includeHidden: nil, level: nil, name: nil, pressed: nil, selected: nil) ⇒ Object
Allows locating elements by their [ARIA role](www.w3.org/TR/wai-aria-1.2/#roles), [ARIA attributes](www.w3.org/TR/wai-aria-1.2/#aria-attributes) and [accessible name](w3c.github.io/accname/#dfn-accessible-name).
Usage
Consider the following DOM structure.
“‘html <h3>Sign up</h3> <label>
<input type="checkbox" /> Subscribe
</label> <br/> <button>Submit</button> “‘
You can locate each element by it’s implicit role:
“‘python sync expect(page.get_by_role(“heading”, name=“Sign up”)).to_be_visible()
page.get_by_role(“checkbox”, name=“Subscribe”).check()
page.get_by_role(“button”, name=re.compile(“submit”, re.IGNORECASE)).click() “‘
Details
Role selector **does not replace** accessibility audits and conformance tests, but rather gives early feedback about the ARIA guidelines.
Many html elements have an implicitly [defined role](w3c.github.io/html-aam/#html-element-role-mappings) that is recognized by the role selector. You can find all the [supported roles here](www.w3.org/TR/wai-aria-1.2/#role_definitions). ARIA guidelines **do not recommend** duplicating implicit roles and attributes by setting ‘role` and/or `aria-*` attributes to default values.

#get_by_test_id(testId) ⇒ Object
Locate element by the test id.
Usage
Consider the following DOM structure.
“‘html <button data-testid=“directions”>Itinéraire</button> “`
You can locate the element by it’s test id:
“‘python sync page.get_by_test_id(“directions”).click() “`
Details
By default, the ‘data-testid` attribute is used as a test id. Use [`method: Selectors.setTestIdAttribute`] to configure a different test id attribute if necessary.

#get_by_text(text, exact: nil) ⇒ Object
Allows locating elements that contain given text.
See also [‘method: Locator.filter`] that allows to match by another criteria, like an accessible role, and then filter by the text content.
Usage
Consider the following DOM structure:
“‘html <div>Hello <span>world</span></div> <div>Hello</div> “`
You can locate by text substring, exact string, or a regular expression:
“‘python sync # Matches <span> page.get_by_text(“world”)
# Matches first <div> page.get_by_text(“Hello world”)
# Matches second <div> page.get_by_text(“Hello”, exact=True)
# Matches both <div>s page.get_by_text(re.compile(“Hello”))
# Matches second <div> page.get_by_text(re.compile(“^hello$”, re.IGNORECASE)) “‘
Details
Matching by text always normalizes whitespace, even with exact match. For example, it turns multiple spaces into one, turns line breaks into spaces and ignores leading and trailing whitespace.
Input elements of the type ‘button` and `submit` are matched by their `value` instead of the text content. For example, locating by text `“Log in”` matches `<input type=button value=“Log in”>`.

#get_by_title(text, exact: nil) ⇒ Object
Allows locating elements by their title attribute.
Usage
Consider the following DOM structure.
“‘html <span title=’Issues count’>25 issues</span> “‘
You can check the issues count after locating it by the title text:
“‘python sync expect(page.get_by_title(“Issues count”)).to_have_text(“25 issues”) “`

#go_back(timeout: nil, waitUntil: nil) ⇒ Object
Returns the main resource response. In case of multiple redirects, the navigation will resolve with the response of the last redirect. If can not go back, returns ‘null`.
Navigate to the previous page in history.

#goto(url, referer: nil, timeout: nil, waitUntil: nil) ⇒ Object
Returns the main resource response. In case of multiple redirects, the navigation will resolve with the first non-redirect response.
The method will throw an error if:
-
there’s an SSL error (e.g. in case of self-signed certificates).
-
target URL is invalid.
-
the ‘timeout` is exceeded during navigation.
-
the remote server does not respond or is unreachable.
-
the main resource failed to load.
The method will not throw an error when any valid HTTP status code is returned by the remote server, including 404 “Not Found” and 500 “Internal Server Error”. The status code for such responses can be retrieved by calling [‘method: Response.status`].
NOTE: The method either throws an error or returns a main resource response. The only exceptions are navigation to ‘about:blank` or navigation to the same URL with a different hash, which would succeed and return `null`.
NOTE: Headless mode doesn’t support navigation to a PDF document. See the [upstream issue](bugs.chromium.org/p/chromium/issues/detail?id=761295).

#hidden?(selector, strict: nil, timeout: nil) ⇒ Boolean
Returns whether the element is hidden, the opposite of [visible](../actionability.md#visible). ‘selector` that does not match any elements is considered hidden.

#hover(selector, force: nil, modifiers: nil, noWaitAfter: nil, position: nil, strict: nil, timeout: nil, trial: nil) ⇒ Object
This method hovers over an element matching ‘selector` by performing the following steps:
-
Find an element matching ‘selector`. If there is none, wait until a matching element is attached to the DOM.
-
Wait for [actionability](../actionability.md) checks on the matched element, unless ‘force` option is set. If the element is detached during the checks, the whole action is retried.
-
Scroll the element into view if needed.
-
Use [‘property: Page.mouse`] to hover over the center of the element, or the specified `position`.
-
Wait for initiated navigations to either succeed or fail, unless ‘noWaitAfter` option is set.
When all steps combined have not finished during the specified ‘timeout`, this method throws a `TimeoutError`. Passing zero timeout disables this.

#input_value(selector, strict: nil, timeout: nil) ⇒ Object
Returns ‘input.value` for the selected `<input>` or `<textarea>` or `<select>` element.
Throws for non-input elements. However, if the element is inside the ‘<label>` element that has an associated [control](developer.mozilla.org/en-US/docs/Web/API/HTMLLabelElement/control), returns the value of the control.

#locator(selector, has: nil, hasText: nil) ⇒ Object
The method returns an element locator that can be used to perform actions on this page / frame. Locator is resolved to the element immediately before performing an action, so a series of actions on the same locator can in fact be performed on different DOM elements. That would happen if the DOM structure between those actions has changed.

#pause ⇒ Object
Pauses script execution. Playwright will stop executing the script and wait for the user to either press ‘Resume’ button in the page overlay or to call ‘playwright.resume()` in the DevTools console.
User can inspect selectors or perform manual steps while paused. Resume will continue running the original script from the place it was paused.
NOTE: This method requires Playwright to be started in a headed mode, with a falsy ‘headless` value in the [`method: BrowserType.launch`].

#pdf(displayHeaderFooter: nil, footerTemplate: nil, format: nil, headerTemplate: nil, height: nil, landscape: nil, margin: nil, pageRanges: nil, path: nil, preferCSSPageSize: nil, printBackground: nil, scale: nil, width: nil) ⇒ Object
Returns the PDF buffer.
NOTE: Generating a pdf is currently only supported in Chromium headless.
‘page.pdf()` generates a pdf of the page with `print` css media. To generate a pdf with `screen` media, call
- ‘method: Page.emulateMedia`
-
before calling ‘page.pdf()`:
NOTE: By default, ‘page.pdf()` generates a pdf with modified colors for printing. Use the [`-webkit-print-color-adjust`](developer.mozilla.org/en-US/docs/Web/CSS/-webkit-print-color-adjust) property to force rendering of exact colors.
Usage
“‘python sync # generates a pdf with “screen” media type. page.emulate_media(media=“screen”) page.pdf(path=“page.pdf”) “`
The ‘width`, `height`, and `margin` options accept values labeled with units. Unlabeled values are treated as pixels.
A few examples:
-
‘page.pdf(100)` - prints with width set to 100 pixels
-
‘page.pdf(’100px’)‘ - prints with width set to 100 pixels
-
‘page.pdf(’10cm’)‘ - prints with width set to 10 centimeters.
All possible units are:
-
‘px` - pixel
-
‘in` - inch
-
‘cm` - centimeter
-
‘mm` - millimeter
The ‘format` options are:
-
‘Letter`: 8.5in x 11in
-
‘Legal`: 8.5in x 14in
-
‘Tabloid`: 11in x 17in
-
‘Ledger`: 17in x 11in
-
‘A0`: 33.1in x 46.8in
-
‘A1`: 23.4in x 33.1in
-
‘A2`: 16.54in x 23.4in
-
‘A3`: 11.7in x 16.54in
-
‘A4`: 8.27in x 11.7in
-
‘A5`: 5.83in x 8.27in
-
‘A6`: 4.13in x 5.83in
NOTE: ‘headerTemplate` and `footerTemplate` markup have the following limitations: > 1. Script tags inside templates are not evaluated. > 2. Page styles are not visible inside templates.

#press(selector, key, delay: nil, noWaitAfter: nil, strict: nil, timeout: nil) ⇒ Object
Focuses the element, and then uses [‘method: Keyboard.down`] and [`method: Keyboard.up`].
‘key` can specify the intended [keyboardEvent.key](developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key) value or a single character to generate the text for. A superset of the `key` values can be found [here](developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key/Key_Values). Examples of the keys are:
‘F1` - `F12`, `Digit0`- `Digit9`, `KeyA`- `KeyZ`, `Backquote`, `Minus`, `Equal`, `Backslash`, `Backspace`, `Tab`, `Delete`, `Escape`, `ArrowDown`, `End`, `Enter`, `Home`, `Insert`, `PageDown`, `PageUp`, `ArrowRight`, `ArrowUp`, etc.
Following modification shortcuts are also supported: ‘Shift`, `Control`, `Alt`, `Meta`, `ShiftLeft`.
Holding down ‘Shift` will type the text that corresponds to the `key` in the upper case.
If ‘key` is a single character, it is case-sensitive, so the values `a` and `A` will generate different respective texts.
Shortcuts such as ‘key: “Control+o”` or `key: “Control+Shift+T”` are supported as well. When specified with the modifier, modifier is pressed and being held while the subsequent key is being pressed.
Usage
“‘python sync page = browser.new_page() page.goto(“keycode.info”) page.press(“body”, “A”) page.screenshot(path=“a.png”) page.press(“body”, “ArrowLeft”) page.screenshot(path=“arrow_left.png”) page.press(“body”, “Shift+O”) page.screenshot(path=“o.png”) browser.close() “`

API testing helper associated with this page. This method returns the same instance as
- ‘property: BrowserContext.request`
-
on the page’s context. See [‘property: BrowserContext.request`] for more details.

#route(url, handler, times: nil) ⇒ Object
Routing provides the capability to modify network requests that are made by a page.
Once routing is enabled, every request matching the url pattern will stall unless it’s continued, fulfilled or aborted.
NOTE: The handler will only be called for the first url if the response is a redirect.
NOTE: [‘method: Page.route`] will not intercept requests intercepted by Service Worker. See [this](github.com/microsoft/playwright/issues/1090) issue. We recommend disabling Service Workers when using request interception by setting `Browser.newContext.serviceWorkers` to `’block’‘.
Usage
An example of a naive handler that aborts all image requests:
“‘python sync page = browser.new_page() page.route(“*/.png,jpg,jpeg”, lambda route: route.abort()) page.goto(“example.com”) browser.close() “`
or the same snippet using a regex pattern instead:
“‘python sync page = browser.new_page() page.route(re.compile(r“(.png$)|(.jpg$)”), lambda route: route.abort()) page.goto(“example.com”) browser.close() “`
It is possible to examine the request to decide the route action. For example, mocking all requests that contain some post data, and leaving all other requests as is:
“‘python sync def handle_route(route):
if ("my-string" in route.request.post_data)
route.fulfill(body="mocked-data")
else
route.continue_()
page.route(“/api/**”, handle_route) “‘
Page routes take precedence over browser context routes (set up with [‘method: BrowserContext.route`]) when request matches both handlers.
To remove a route with its handler you can use [‘method: Page.unroute`].
NOTE: Enabling routing disables http cache.

#route_from_har(har, notFound: nil, update: nil, url: nil) ⇒ Object
If specified the network requests that are made in the page will be served from the HAR file. Read more about [Replaying from HAR](../network.md#replaying-from-har).
Playwright will not serve requests intercepted by Service Worker from the HAR file. See [this](github.com/microsoft/playwright/issues/1090) issue. We recommend disabling Service Workers when using request interception by setting ‘Browser.newContext.serviceWorkers` to `’block’‘.

#select_option(selector, element: nil, index: nil, value: nil, label: nil, force: nil, noWaitAfter: nil, strict: nil, timeout: nil) ⇒ Object
This method waits for an element matching ‘selector`, waits for [actionability](../actionability.md) checks, waits until all specified options are present in the `<select>` element and selects these options.
If the target element is not a ‘<select>` element, this method throws an error. However, if the element is inside the `<label>` element that has an associated [control](developer.mozilla.org/en-US/docs/Web/API/HTMLLabelElement/control), the control will be used instead.
Returns the array of option values that have been successfully selected.
Triggers a ‘change` and `input` event once all the provided options have been selected.
Usage
“‘python sync # single selection matching the value page.select_option(“select#colors”, “blue”) # single selection matching both the label page.select_option(“select#colors”, label=“blue”) # multiple selection page.select_option(“select#colors”, value=[“red”, “green”, “blue”]) “`

#set_checked(selector, checked, force: nil, noWaitAfter: nil, position: nil, strict: nil, timeout: nil, trial: nil) ⇒ Object
This method checks or unchecks an element matching ‘selector` by performing the following steps:
-
Find an element matching ‘selector`. If there is none, wait until a matching element is attached to the DOM.
-
Ensure that matched element is a checkbox or a radio input. If not, this method throws.
-
If the element already has the right checked state, this method returns immediately.
-
Wait for [actionability](../actionability.md) checks on the matched element, unless ‘force` option is set. If the element is detached during the checks, the whole action is retried.
-
Scroll the element into view if needed.
-
Use [‘property: Page.mouse`] to click in the center of the element.
-
Wait for initiated navigations to either succeed or fail, unless ‘noWaitAfter` option is set.
-
Ensure that the element is now checked or unchecked. If not, this method throws.
When all steps combined have not finished during the specified ‘timeout`, this method throws a `TimeoutError`. Passing zero timeout disables this.

Sets the value of the file input to these file paths or files. If some of the ‘filePaths` are relative paths, then they are resolved relative to the current working directory. For empty array, clears the selected files.
This method expects ‘selector` to point to an [input element](developer.mozilla.org/en-US/docs/Web/HTML/Element/input). However, if the element is inside the `<label>` element that has an associated [control](developer.mozilla.org/en-US/docs/Web/API/HTMLLabelElement/control), targets the control instead.

#set_viewport_size(viewportSize) ⇒ Object Also known as: viewport_size=
In the case of multiple pages in a single browser, each page can have its own viewport size. However,
- ‘method: Browser.newContext`
-
allows to set viewport size (and more) for all pages in the context at once.
- ‘method: Page.setViewportSize`
-
will resize the page. A lot of websites don’t expect phones to change size, so you should set the
viewport size before navigating to the page. [‘method: Page.setViewportSize`] will also reset `screen` size, use [`method: Browser.newContext`] with `screen` and `viewport` parameters if you need better control of these properties.
Usage
“‘python sync page = browser.new_page() page.set_viewport_size(640, “height”: 480) page.goto(“example.com”) “`

#tap_point(selector, force: nil, modifiers: nil, noWaitAfter: nil, position: nil, strict: nil, timeout: nil, trial: nil) ⇒ Object
This method taps an element matching ‘selector` by performing the following steps:
-
Find an element matching ‘selector`. If there is none, wait until a matching element is attached to the DOM.
-
Wait for [actionability](../actionability.md) checks on the matched element, unless ‘force` option is set. If the element is detached during the checks, the whole action is retried.
-
Scroll the element into view if needed.
-
Use [‘property: Page.touchscreen`] to tap the center of the element, or the specified `position`.
-
Wait for initiated navigations to either succeed or fail, unless ‘noWaitAfter` option is set.
When all steps combined have not finished during the specified ‘timeout`, this method throws a `TimeoutError`. Passing zero timeout disables this.
NOTE: [‘method: Page.tap`] the method will throw if `hasTouch` option of the browser context is false.

#type(selector, text, delay: nil, noWaitAfter: nil, strict: nil, timeout: nil) ⇒ Object
Sends a ‘keydown`, `keypress`/`input`, and `keyup` event for each character in the text. `page.type` can be used to send fine-grained keyboard events. To fill values in form fields, use [`method: Page.fill`].
To press a special key, like ‘Control` or `ArrowDown`, use [`method: Keyboard.press`].
Usage
“‘python sync page.type(“#mytextarea”, “hello”) # types instantly page.type(“#mytextarea”, “world”, delay=100) # types slower, like a user “`

#uncheck(selector, force: nil, noWaitAfter: nil, position: nil, strict: nil, timeout: nil, trial: nil) ⇒ Object
This method unchecks an element matching ‘selector` by performing the following steps:
-
Find an element matching ‘selector`. If there is none, wait until a matching element is attached to the DOM.
-
Ensure that matched element is a checkbox or a radio input. If not, this method throws. If the element is already unchecked, this method returns immediately.
-
Wait for [actionability](../actionability.md) checks on the matched element, unless ‘force` option is set. If the element is detached during the checks, the whole action is retried.
-
Scroll the element into view if needed.
-
Use [‘property: Page.mouse`] to click in the center of the element.
-
Wait for initiated navigations to either succeed or fail, unless ‘noWaitAfter` option is set.
-
Ensure that the element is now unchecked. If not, this method throws.
When all steps combined have not finished during the specified ‘timeout`, this method throws a `TimeoutError`. Passing zero timeout disables this.

#wait_for_event(event, predicate: nil, timeout: nil) ⇒ Object
NOTE: In most cases, you should use [‘method: Page.waitForEvent`].
Waits for given ‘event` to fire. If predicate is provided, it passes event’s value into the ‘predicate` function and waits for `predicate(event)` to return a truthy value. Will throw an error if the page is closed before the `event` is fired.
1658 1659 1660 |
# File 'lib/playwright_api/page.rb', line 1658 def wait_for_event(event, predicate: nil, timeout: nil) raise NotImplementedError.new('wait_for_event is not implemented yet.') end |
#wait_for_function(expression, arg: nil, polling: nil, timeout: nil) ⇒ Object
Returns when the ‘expression` returns a truthy value. It resolves to a JSHandle of the truthy value.
Usage
The [‘method: Page.waitForFunction`] can be used to observe viewport size change:
“‘python sync from playwright.sync_api import sync_playwright
def run(playwright):
webkit = playwright.webkit
browser = webkit.launch()
page = browser.new_page()
page.evaluate("window.x = 0; setTimeout(() => { window.x = 100 }, 1000);")
page.wait_for_function("() => window.x > 0")
browser.close()
with sync_playwright() as playwright:
run(playwright)
“‘
To pass an argument to the predicate of [‘method: Page.waitForFunction`] function:
“‘python sync selector = “.foo” page.wait_for_function(“selector => !!document.querySelector(selector)”, selector) “`

#wait_for_load_state(state: nil, timeout: nil) ⇒ Object
Returns when the required load state has been reached.
This resolves when the page reaches a required load state, ‘load` by default. The navigation must have been committed when this method is called. If current document has already reached the required state, resolves immediately.
Usage
“‘python sync page.get_by_role(“button”).click() # click triggers navigation. page.wait_for_load_state() # the promise resolves after “load” event. “`
“‘python sync with page.expect_popup() as page_info:
page.get_by_role("button").click() # click triggers a popup.
popup = page_info.value # Wait for the “DOMContentLoaded” event. popup.wait_for_load_state(“domcontentloaded”) print(popup.title()) # popup is ready to use. “‘

# File 'lib/playwright_api/page.rb', line 1478 def wait_for_load_state(state: nil, timeout: nil) wrap_impl(@impl.wait_for_load_state(state: unwrap_impl(state), timeout: unwrap_impl(timeout))) end |
#wait_for_selector(selector, state: nil, strict: nil, timeout: nil) ⇒ Object
Returns when element specified by selector satisfies ‘state` option. Returns `null` if waiting for `hidden` or `detached`.
NOTE: Playwright automatically waits for element to be ready before performing an action. Using ‘Locator` objects and web-first assertions makes the code wait-for-selector-free.
Wait for the ‘selector` to satisfy `state` option (either appear/disappear from dom, or become visible/hidden). If at the moment of calling the method `selector` already satisfies the condition, the method will return immediately. If the selector doesn’t satisfy the condition for the ‘timeout` milliseconds, the function will throw.
Usage
This method works across navigations:
“‘python sync from playwright.sync_api import sync_playwright
def run(playwright):
chromium = playwright.chromium
browser = chromium.launch()
page = browser.new_page()
for current_url in ["https://google.com", "https://bbc.com"]:
page.goto(current_url, wait_until="domcontentloaded")
element = page.wait_for_selector("img")
print("Loaded image: " + str(element.get_attribute("src")))
browser.close()
with sync_playwright() as playwright:
run(playwright)

#wait_for_timeout(timeout) ⇒ Object
Waits for the given ‘timeout` in milliseconds.
Note that ‘page.waitForTimeout()` should only be used for debugging. Tests using the timer in production are going to be flaky. Use signals such as network events, selectors becoming visible and others instead.
