Page
- extends: EventEmitter
Page provides methods to interact with a single tab in a Browser, or an extension background page 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:
The Page class emits various events (described below) which can be handled using any of Node's native EventEmitter
methods, such as on
, once
or removeListener
.
This example logs a message for a single page load
event:
To unsubscribe from events use the removeListener
method:

#
page.on('close')Emitted when the page closes.
#
page.on('console')- type: <ConsoleMessage>
Emitted when JavaScript within the page calls one of console API methods, e.g. console.log
or console.dir
. Also emitted if the page throws an error or a warning.
The arguments passed into console.log
appear as arguments on the event handler.
An example of handling console
event:
#
page.on('crash')Emitted when the page crashes. Browser pages might crash if they try to allocate too much memory. When the page crashes, ongoing and subsequent operations will throw.
The most common way to deal with crashes is to catch an exception:
#
page.on('dialog')- type: <Dialog>
Emitted when a JavaScript dialog appears, such as alert
, prompt
, confirm
or beforeunload
. Playwright can respond to the dialog via dialog.accept([promptText]) or dialog.dismiss() methods.
#
page.on('domcontentloaded')Emitted when the JavaScript DOMContentLoaded
event is dispatched.
#
page.on('download')- type: <Download>
Emitted when attachment download started. User can access basic file operations on downloaded content via the passed Download instance.
note
Browser context must be created with the acceptDownloads
set to true
when user needs access to the downloaded content. If acceptDownloads
is not set, download events are emitted, but the actual download is not performed and user has no access to the downloaded files.
#
page.on('filechooser')- type: <FileChooser>
Emitted when a file chooser is supposed to appear, such as after clicking the <input type=file>
. Playwright can respond to it via setting the input files using fileChooser.setFiles(files[, options]) that can be uploaded after that.
#
page.on('frameattached')- type: <Frame>
Emitted when a frame is attached.
#
page.on('framedetached')- type: <Frame>
Emitted when a frame is detached.
#
page.on('framenavigated')- type: <Frame>
Emitted when a frame is navigated to a new url.
#
page.on('load')Emitted when the JavaScript load
event is dispatched.
#
page.on('pageerror')- type: <Error>
Emitted when an uncaught exception happens within the page.
#
page.on('popup')- type: <Page>
Emitted when the page opens a new tab or window. This event is emitted in addition to the browserContext.on('page'), but only for popups relevant to this page.
The earliest moment that page is available is when it has navigated to the initial url. For example, when opening a popup with window.open('http://example.com')
, this event will fire when the network request to "http://example.com" is done and its response has started loading in the popup.
note
Use page.waitForLoadState([state, options]) to wait until the page gets to a particular state (you should not need it in most cases).
#
page.on('request')- type: <Request>
Emitted when a page issues a request. The request object is read-only. In order to intercept and mutate requests, see page.route(url, handler) or browserContext.route(url, handler).
#
page.on('requestfailed')- type: <Request>
Emitted when a request fails, for example by timing out.
note
HTTP Error responses, such as 404 or 503, are still successful responses from HTTP standpoint, so request will complete with page.on('requestfinished') event and not with page.on('requestfailed').
#
page.on('requestfinished')- type: <Request>
Emitted when a request finishes successfully after downloading the response body. For a successful response, the sequence of events is request
, response
and requestfinished
.
#
page.on('response')- type: <Response>
Emitted when response status and headers are received for a request. For a successful response, the sequence of events is request
, response
and requestfinished
.
#
page.on('websocket')- type: <WebSocket>
Emitted when <WebSocket> request is sent.
#
page.on('worker')- type: <Worker>
Emitted when a dedicated WebWorker is spawned by the page.
#
page.$(selector)selector
<string> A selector to query for. See working with selectors for more details.- returns: <Promise<null|ElementHandle>>
The method finds an element matching the specified selector within the page. If no elements match the selector, the return value resolves to null
.
Shortcut for main frame's frame.$(selector).
#
page.$$(selector)selector
<string> A selector to query for. See working with selectors for more details.- returns: <Promise<Array<ElementHandle>>>
The method finds all elements matching the specified selector within the page. If no elements match the selector, the return value resolves to []
.
Shortcut for main frame's frame.$$(selector).
#
page.$eval(selector, pageFunction[, arg])selector
<string> A selector to query for. See working with selectors for more details.pageFunction
<function(Element)> Function to be evaluated in browser contextarg
<[EvaluationArgument]> Optional argument to pass topageFunction
- returns: <Promise<Serializable>>
The method finds an element matching the specified selector within the page and passes it as a first argument to pageFunction
. If no elements match the selector, the method throws an error. Returns the value of pageFunction
.
If pageFunction
returns a Promise, then page.$eval(selector, pageFunction[, arg]) would wait for the promise to resolve and return its value.
Examples:
Shortcut for main frame's frame.$eval(selector, pageFunction[, arg]).
#
page.$$eval(selector, pageFunction[, arg])selector
<string> A selector to query for. See working with selectors for more details.pageFunction
<function(Array<Element>)> Function to be evaluated in browser contextarg
<[EvaluationArgument]> Optional argument to pass topageFunction
- returns: <Promise<Serializable>>
The method finds all elements matching the specified selector within the page and passes an array of matched elements as a first argument to pageFunction
. Returns the result of pageFunction
invocation.
If pageFunction
returns a Promise, then page.$$eval(selector, pageFunction[, arg]) would wait for the promise to resolve and return its value.
Examples:
#
page.addInitScript(script[, arg])script
<function|string|Object> Script to be evaluated in the page.arg
<Serializable> Optional argument to pass toscript
(only supported when passing a function).
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:
note
The order of evaluation of multiple scripts installed via browserContext.addInitScript(script[, arg]) and page.addInitScript(script[, arg]) is not defined.
#
page.addScriptTag([options])options

#
page.addStyleTag([options])options
<Object>- returns: <Promise<ElementHandle>>
Adds a <link rel="stylesheet">
tag into the page with the desired url or a <style type="text/css">
tag with the content. Returns the added tag when the stylesheet's onload fires or when the CSS content was injected into frame.
Shortcut for main frame's frame.addStyleTag([options]).
#
page.bringToFront()Brings page to front (activates tab).
#
page.check(selector[, options])selector
<string> A selector to search for element. If there are multiple elements satisfying the selector, the first will be used. See working with selectors for more details.options
<Object>force
<boolean> Whether to bypass the actionability checks. Defaults tofalse
.noWaitAfter
<boolean> Actions that initiate navigations are waiting for these navigations to happen and for pages to start loading. You can opt out of waiting via setting this flag. You would only need this option in the exceptional cases such as navigating to inaccessible pages. Defaults tofalse
.timeout
<number> Maximum time in milliseconds, defaults to 30 seconds, pass0
to disable timeout. The default value can be changed by using the browserContext.setDefaultTimeout(timeout) or page.setDefaultTimeout(timeout) methods.
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 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 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 rejects.
When all steps combined have not finished during the specified timeout
, this method rejects with a TimeoutError. Passing zero timeout disables this.

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 page.on('dialog') event.

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 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 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 thedblclick()
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.
Shortcut for main frame's frame.dblclick(selector[, options]).
#
page.dispatchEvent(selector, type[, eventInit, options])selector
<string> A selector to search for element. If there are multiple elements satisfying the selector, the first will be used. See working with selectors for more details.type
<string> DOM event type:"click"
,"dragstart"
, etc.eventInit
<[EvaluationArgument]> Optional event-specific initialization properties.options
<Object>timeout
<number> Maximum time in milliseconds, defaults to 30 seconds, pass0
to disable timeout. The default value can be changed by using the browserContext.setDefaultTimeout(timeout) or page.setDefaultTimeout(timeout) methods.
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().
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:
#
page.emulateMedia(params)params
<Object>media
<null|"screen"|"print"> Changes the CSS media type of the page. The only allowed values are'screen'
,'print'
andnull
. Passingnull
disables CSS media emulation. Omittingmedia
or passingundefined
does not change the emulated value. Optional.colorScheme
<null|"light"|"dark"|"no-preference"> Emulates'prefers-colors-scheme'
media feature, supported values are'light'
,'dark'
,'no-preference'
. Passingnull
disables color scheme emulation. OmittingcolorScheme
or passingundefined
does not change the emulated value. Optional.
#
page.evaluate(pageFunction[, arg])pageFunction
<function|string> Function to be evaluated in the page contextarg
<[EvaluationArgument]> Optional argument to pass topageFunction
- returns: <Promise<Serializable>>
Returns the value of the pageFunction
invocation.
If the function passed to the page.evaluate(pageFunction[, arg]) returns a Promise, then page.evaluate(pageFunction[, arg]) would wait for the promise to resolve and return its value.
If the function passed to the page.evaluate(pageFunction[, arg]) returns a non-Serializable value, then page.evaluate(pageFunction[, arg]) 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
:
A string can also be passed in instead of a function:
ElementHandle instances can be passed as an argument to the page.evaluate(pageFunction[, arg]):
Shortcut for main frame's frame.evaluate(pageFunction[, arg]).
#
page.evaluateHandle(pageFunction[, arg])pageFunction
<function|string> Function to be evaluated in the page contextarg
<[EvaluationArgument]> Optional argument to pass topageFunction
- returns: <Promise<JSHandle>>
Returns the value of the pageFunction
invocation as in-page object (JSHandle).
The only difference between page.evaluate(pageFunction[, arg]) and page.evaluateHandle(pageFunction[, arg]) is that page.evaluateHandle(pageFunction[, arg]) returns in-page object (JSHandle).
If the function passed to the page.evaluateHandle(pageFunction[, arg]) returns a Promise, then page.evaluateHandle(pageFunction[, arg]) would wait for the promise to resolve and return its value.
A string can also be passed in instead of a function:
JSHandle instances can be passed as an argument to the page.evaluateHandle(pageFunction[, arg]):
#
page.exposeBinding(name, callback[, options])name
<string> Name of the function on the window object.callback
<function> Callback function that will be called in the Playwright's context.options
<Object>handle
<boolean> Whether to pass the argument as a handle, instead of passing by value. When passing a handle, only one argument is supported. When passing by value, multiple arguments are supported.
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 browserContext.exposeBinding(name, callback[, options]) for the context-wide version.
note
Functions installed via page.exposeBinding(name, callback[, options]) survive navigations.

.timeout
<number> Maximum time in milliseconds, defaults to 30 seconds, pass0
to disable timeout. The default value can be changed by using the browserContext.setDefaultTimeout(timeout) or page.setDefaultTimeout(timeout) methods.
This method waits for an element matching selector
, waits for actionability checks, focuses the element, fills it and triggers an input
event after filling. If the element matching selector
is not an <input>

to disable timeout. The default value can be changed by using the browserContext.setDefaultTimeout(timeout) or page.setDefaultTimeout(timeout) methods.
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 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 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 rejects with a TimeoutError. Passing zero timeout disables this.
Shortcut for main frame's frame.hover(selector[, options]).

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:
or the same snippet using a regex pattern instead:
Page routes take precedence over browser context routes (set up with browserContext.route(url, handler)) when request matches both handlers.
