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) “‘

#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`.

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, timeout: nil, trial: nil) ⇒ Object

This method checks an element matching ‘selector` by performing the following steps:

  1. Find an element matching ‘selector`. If there is none, wait until a matching element is attached to the DOM.

  2. 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.

  3. 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.

  4. Scroll the element into view if needed.

  5. Use [‘property: Page.mouse`] to click in the center of the element.

  6. Wait for initiated navigations to either succeed or fail, unless ‘noWaitAfter` option is set.

  7. 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.

#click(selector, button: nil, clickCount: nil, delay: nil, force: nil, modifiers: nil, noWaitAfter: nil, position: nil, timeout: nil, trial: nil) ⇒ Object

This method clicks an element matching ‘selector` by performing the following steps:

  1. Find an element matching ‘selector`. If there is none, wait until a matching element is attached to the DOM.

  2. 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.

  3. Scroll the element into view if needed.

  4. Use [‘property: Page.mouse`] to click in the center of the element, or the specified `position`.

  5. 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.

end

#close(runBeforeUnload: nil) ⇒ Object

If ‘runBeforeUnload` is `false`, does not run any unload handlers and waits for the page to be closed. If `runBeforeUnload` is `true` the method will run unload handlers, but will not wait for the page to close.

By default, ‘page.close()` **does not** run `beforeunload` handlers.

> NOTE: if ‘runBeforeUnload` is passed as true, a `beforeunload` dialog might be summoned and should be handled manually via [`event: Page.dialog`] event.

#dblclick(selector, button: nil, delay: nil, force: nil, modifiers: nil, noWaitAfter: nil, position: nil, timeout: nil, trial: nil) ⇒ Object

This method double clicks an element matching ‘selector` by performing the following steps:

  1. Find an element matching ‘selector`. If there is none, wait until a matching element is attached to the DOM.

  2. 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.

  3. Scroll the element into view if needed.

  4. Use [‘property: Page.mouse`] to double click in the center of the element, or the specified `position`.

  5. 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.

end

#dispatch_event(selector, type, eventInit: 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).

“‘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:

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 }) “`

#emulate_media(colorScheme: nil, media: 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.

“‘python sync page.evaluate(“matchMedia(’screen’).matches”) # → True page.evaluate(“matchMedia(‘print’).matches”) # → False

page.emulate_media(media=“print”) page.evaluate(“matchMedia(‘screen’).matches”) # → False page.evaluate(“matchMedia(‘print’).matches”) # → True

page.emulate_media() page.evaluate(“matchMedia(‘screen’).matches”) # → True page.evaluate(“matchMedia(‘print’).matches”) # → False “‘

“‘python sync page.emulate_media(color_scheme=“dark”) page.evaluate(“matchMedia(’(prefers-color-scheme: dark)‘).matches”) # → True page.evaluate(“matchMedia(’(prefers-color-scheme: light)‘).matches”) # → False page.evaluate(“matchMedia(’(prefers-color-scheme: no-preference)‘).matches”) “`

#eval_on_selector(selector, expression, arg: 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.

Examples:

“‘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“) “`

end

#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.

Examples:

“‘python sync div_counts = page.eval_on_selector_all(“div”, “(divs, min) => divs.length >= min”, 10) “`

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`.

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.query_selector(“body”) html = page.evaluate(“([body, suffix]) => body.innerHTML + suffix”, [body_handle, “hello”]) body_handle.dispose() “`

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.

“‘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 console event is fired.

#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`.

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():

page.click("a.delayed-navigation") # clicking the link will indirectly cause a navigation

# 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.

#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.

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()
page.expose_binding("pageURL", lambda source: source["page"].url)
page.set_content("""

    document.querySelector('div').textContent = await window.pageURL();
  }
</script>
<button onclick="onClick()">Click me</button>
<div></div>
""")
page.click("button")

with sync_playwright() as playwright:

run(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.

#fill(selector, value, noWaitAfter: 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`].

#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 response of the last redirect.

‘page.goto` 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.

‘page.goto` 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: ‘page.goto` 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).

#hover(selector, force: nil, modifiers: nil, position: nil, timeout: nil, trial: nil) ⇒ Object

This method hovers over an element matching ‘selector` by performing the following steps:

  1. Find an element matching ‘selector`. If there is none, wait until a matching element is attached to the DOM.

  2. 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.

  3. Scroll the element into view if needed.

  4. Use [‘property: Page.mouse`] to hover over the center of the element, or the specified `position`.

  5. 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.

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.

“‘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, 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.

“‘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() “`

#route(url, handler) ⇒ 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.

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.

#select_option(selector, element: nil, index: nil, value: nil, label: nil, noWaitAfter: 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.

“‘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_input_files(selector, files, noWaitAfter: nil, timeout: nil) ⇒ Object

This method expects ‘selector` to point to an [input element](developer.mozilla.org/en-US/docs/Web/HTML/Element/input).

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 the current working directory. For empty array, clears the selected files.

#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.

‘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.

“‘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, timeout: nil, trial: nil) ⇒ Object

This method taps an element matching ‘selector` by performing the following steps:

  1. Find an element matching ‘selector`. If there is none, wait until a matching element is attached to the DOM.

  2. 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.

  3. Scroll the element into view if needed.

  4. Use [‘property: Page.touchscreen`] to tap the center of the element, or the specified `position`.

  5. 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`] requires that the `hasTouch` option of the browser context be set to true.

Shortcut for main frame’s [‘method: Frame.tap`].

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`].

#uncheck(selector, force: nil, noWaitAfter: nil, position: nil, timeout: nil, trial: nil) ⇒ Object

This method unchecks an element matching ‘selector` by performing the following steps:

  1. Find an element matching ‘selector`. If there is none, wait until a matching element is attached to the DOM.

  2. 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.

  3. 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.

  4. Scroll the element into view if needed.

  5. Use [‘property: Page.mouse`] to click in the center of the element.

  6. Wait for initiated navigations to either succeed or fail, unless ‘noWaitAfter` option is set.

  7. 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.

Raises:

  • (NotImplementedError)

#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.

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) “`

end

#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.

“‘python sync page.click(“button”) # click triggers navigation. page.wait_for_load_state() # the promise resolves after “load” event. “`

“‘python sync with page.expect_popup() as page_info:

page.click("button") # click triggers a popup.

popup = page_info.value

# Following resolves after "domcontentloaded" event.

popup.wait_for_load_state(“domcontentloaded”) print(popup.title()) # popup is ready to use. “‘

end

#wait_for_selector(selector, state: nil, timeout: nil) ⇒ Object

Returns when element specified by selector satisfies ‘state` option. Returns `null` if waiting for `hidden` or `detached`.

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.

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")

#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.
