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:
“‘js const { webkit } = require(’playwright’); // Or ‘chromium’ or ‘firefox’.
(async () =>
const browser = await webkit.launch(); const context = await browser.newContext(); const page = await context.newPage(); await page.goto('https://example.com'); await page.screenshot({path: 'screenshot.png'); await browser.close();})(); “‘
“‘python async import asyncio from playwright.async_api import async_playwright
async def run(playwright):
webkit = playwright.webkit browser = await webkit.launch() context = await browser.new_context() page = await context.new_page() await page.goto("https://example.com") await page.screenshot(path="screenshot.png") await browser.close()async def main():
async with async_playwright() as playwright: await run(playwright)asyncio.run(main()) “‘
“‘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 ason,onceorremoveListener.This example logs a message for a single page
loadevent:“‘js page.once(’load’, () => console.log(‘Page loaded!’)); “‘
“‘py page.once(“load”, lambda: print(“page loaded!”)) “`
To unsubscribe from events use the
removeListenermethod:“‘js function logRequest(interceptedRequest) {
console.log('A request was made:', interceptedRequest.url());} page.on(‘request’, logRequest); // Sometime later… page.removeListener(‘request’, logRequest); “‘
“‘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 95 def accessibility # property wrap_impl(@impl.accessibility) end |
#add_init_script(script, arg: 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:
“‘js browser // preload.js Math.random = () => 42; “`
“‘js // In your playwright script, assuming the preload.js file is in same directory await page.addInitScript({ path: ’./preload.js’ }); “‘
“‘python async # in your playwright script, assuming the preload.js file is in same directory await page.add_init_script(path=“./preload.js”) “`
“‘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, timeout: nil) ⇒ Object
This method checks an element matching selector by performing the following steps:
-
Find an element match 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 rejects. If the element is already checked, this method returns immediately.
-
Wait for [actionability](./actionability.md) checks on the matched element, unless
forceoption 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
noWaitAfteroption is set. -
Ensure that the element is now checked. If not, this method rejects.
When all steps combined have not finished during the specified timeout, this method rejects with a TimeoutError. Passing zero timeout disables this.
Shortcut for main frame’s [‘method: Frame.check`].

#click(selector, button: nil, clickCount: nil, delay: nil, force: nil, modifiers: nil, noWaitAfter: nil, position: nil, timeout: nil) ⇒ Object
This method clicks an element matching selector by performing the following steps:
-
Find an element match 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
forceoption 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, or the specified
position. -
Wait for initiated navigations to either succeed or fail, unless
noWaitAfteroption is set.
When all steps combined have not finished during the specified timeout, this method rejects with a TimeoutError. Passing zero timeout disables this.

#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) ⇒ Object
This method double clicks an element matching selector by performing the following steps:
-
Find an element match 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
forceoption 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
noWaitAfteroption is set. Note that if the first click of the ‘dblclick()` triggers a navigation event, this method will reject.
When all steps combined have not finished during the specified timeout, this method rejects with 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, timeout: nil) ⇒ Object
The snippet below dispatches the click event on the element. Regardless of the visibility state of the elment, click is dispatched. This is equivalend to calling [element.click()](developer.mozilla.org/en-US/docs/Web/API/HTMLElement/click).
“‘js await page.dispatchEvent(’button#submit’, ‘click’); “‘
“‘python async await page.dispatch_event(“button#submit”, “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:
-
[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:
“‘js // Note you can only create DataTransfer in Chromium and Firefox const dataTransfer = await page.evaluateHandle(() => new DataTransfer()); await page.dispatchEvent(’#source’, ‘dragstart’, { dataTransfer }); “‘
“‘python async # note you can only create data_transfer in chromium and firefox data_transfer = await page.evaluate_handle(“new DataTransfer()”) await page.dispatch_event(“#source”, “dragstart”, { “dataTransfer”: data_transfer }) “`
“‘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 }) “`

If pageFunction returns a [Promise], then [‘method: Page.$eval`] would wait for the promise to resolve and return its value.
Examples:
“‘js const searchValue = await page.$eval(’#search’, el => el.value); const preloadHref = await page.$eval(‘link’, el => el.href); const html = await page.$eval(‘.main-container’, (e, suffix) => e.outerHTML + suffix, ‘hello’); “‘

Returns the value of the pageFunction 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. DevTools Protocol also supports transferring some additional values that are not serializable by JSON: -0, NaN, Infinity, -Infinity, and bigint literals.
Passing argument to pageFunction:
“‘js const result = await page.evaluate(([x, y]) =>
return Promise.resolve(x * y);

“‘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:
“‘js console.log(await page.evaluate(’1 + 2’)); // prints “3” const x = 10; console.log(await page.evaluate(‘1 + $x`)); // prints “11” “`

Returns the value of the pageFunction invocation as in-page object (JSHandle).
The only difference between [‘method: Page.evaluate`] and [`method: Page.evaluateHandle`] is that
- ‘method: Page.evaluateHandle`
-
returns in-page object (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.

#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:
“‘js const [response] = await Promise.all([
page.(), // The promise resolves after has finished
page.click('a.delayed-navigation'), // Clicking the link will indirectly cause a
]); “‘
“‘python async async with page.expect_navigation():
await page.click("a.delayed-navigation") # clicking the link will indirectly cause a navigation
# Resolves after navigation has finished “‘
“‘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 }`.

#hover(selector, force: nil, modifiers: nil, position: nil, timeout: nil) ⇒ Object
This method hovers over an element matching selector by performing the following steps:
-
Find an element match 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
forceoption 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
noWaitAfteroption is set.
When all steps combined have not finished during the specified timeout, this method rejects with a TimeoutError. Passing zero timeout disables this.

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 -

#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 speficied with the modifier, modifier is pressed and being held while the subsequent key is being pressed.
“‘js const page = await browser.newPage(); await page.goto(’keycode.info’); await page.press(‘body’, ‘A’); await page.screenshot({ path: ‘A.png’ }); await page.press(‘body’, ‘ArrowLeft’); await page.screenshot({ path: ‘ArrowLeft.png’ }); await page.press(‘body’, ‘Shift+O’); await page.screenshot({ path: ‘O.png’ }); await 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 naïve handler that aborts all image requests:
“‘js const page = await browser.newPage(); await page.route(’*/.png,jpg,jpeg‘, route => route.abort()); await page.goto(’example.com’); await browser.close(); “‘
“‘python async page = await browser.new_page() await page.route(“*/.png,jpg,jpeg”, lambda route: route.abort()) await page.goto(“example.com”) await browser.close() “`
“‘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:
“‘js const page = await browser.newPage(); await page.route(/(.png$)|(.jpg$)/, route => route.abort()); await page.goto(’example.com’); await browser.close(); “‘
“‘python async page = await browser.new_page() await page.route(re.compile(r“(.png$)|(.jpg$)”), lambda route: route.abort()) await page.goto(“example.com”) await browser.close() “`
“‘python sync page = browser.new_page() page.route(re.compile(r“(.png$)|(.jpg$)”), lambda route: route.abort()) page.goto(“example.com”) browser.close() “`
Page routes take precedence over browser context routes (set up with [‘method: BrowserContext.route`]) when request matches both handlers.
> NOTE: Enabling routing disables http cache.

#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`

width: 640,

#tap_point(selector, force: nil, modifiers: nil, noWaitAfter: nil, position: nil, timeout: nil) ⇒ Object
This method taps an element matching selector by performing the following steps:
-
Find an element match 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
forceoption 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
noWaitAfteroption is set.
When all steps combined have not finished during the specified timeout, this method rejects with a TimeoutError. Passing zero timeout disables this.
> NOTE: [‘method: Page.tap`] requires that the hasTouch option of the browser context be set to true.

#uncheck(selector, force: nil, noWaitAfter: nil, timeout: nil) ⇒ Object
This method unchecks an element matching selector by performing the following steps:
-
Find an element match 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 rejects. If the element is already unchecked, this method returns immediately.
-
Wait for [actionability](./actionability.md) checks on the matched element, unless
forceoption 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
noWaitAfteroption is set. -
Ensure that the element is now unchecked. If not, this method rejects.

#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.
