ElementHandle
- extends: JSHandle
ElementHandle represents an in-page DOM element. ElementHandles can be created with the page.$ method.
ElementHandle prevents DOM element from garbage collection unless the handle is disposed. ElementHandles are auto-disposed when their origin frame gets navigated.
ElementHandle instances can be used as an argument in page.$eval()
and page.evaluate()
methods.

elementHandle.$(selector)selector
<string> A selector to query element for. See working with selectors) for more details.- returns: <Promise<?ElementHandle>>
The method finds an element matching the specified selector in the ElementHandle
's subtree. See Working with selectors for more details. If no elements match the selector, the return value resolves to null
.
#
elementHandle.$$(selector)selector
<string> A selector to query element for. See working with selectors for more details.- returns: <Promise<Array<ElementHandle>>>
The method finds all elements matching the specified selector in the ElementHandle
s subtree. See Working with selectors for more details. If no elements match the selector, the return value resolves to []
.
#
elementHandle.$eval(selector, pageFunction[, arg])selector
<string> A selector to query element for. See working with selectors for more details.pageFunction
<function(Element)> Function to be evaluated in browser contextarg
<EvaluationArgument> Optional argument to pass topageFunction
- returns: <Promise<Serializable>> Promise which resolves to the return value of
pageFunction
The method finds an element matching the specified selector in the ElementHandle
s subtree and passes it as a first argument to pageFunction
. See Working with selectors for more details. If no elements match the selector, the method throws an error.
If pageFunction
returns a Promise, then frame.$eval
would wait for the promise to resolve and return its value.
Examples:
#
elementHandle.$$eval(selector, pageFunction[, arg])selector
<string> A selector to query element 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>> Promise which resolves to the return value of
pageFunction
The method finds all elements matching the specified selector in the ElementHandle
's subtree and passes an array of matched elements as a first argument to pageFunction
. See Working with selectors for more details.
If pageFunction
returns a Promise, then frame.$$eval
would wait for the promise to resolve and return its value.
Examples:
#
elementHandle.boundingBox()This method returns the bounding box of the element (relative to the main frame), or null
if the element is not visible.
#
elementHandle.check([options])options
<Object>force
<boolean> Whether to bypass the actionability checks. Defaults tofalse
.noWaitAfter

.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.
- returns: <Promise> Promise which resolves when the element is successfully checked. Promise gets rejected if the operation fails.
This method waits for actionability checks. Then, if the element is not already checked, this method scrolls the element into view and uses elementHandle.click to click in the center of the element.

to disable timeout. The default value can be changed by using the browserContext.setDefaultTimeout(timeout) or page.setDefaultTimeout(timeout) methods.
- returns: <Promise> Promise which resolves when the element is successfully clicked. Promise gets rejected if the element is detached from DOM.
This method waits for actionability checks, then scrolls the element into view if needed and uses page.mouse to click in the center of the element.
If the element is detached from DOM, the method throws an error.
#
elementHandle.contentFrame()- returns: <Promise<?Frame>> Resolves to the content frame for element handles referencing iframe nodes, or
null
otherwise

This method waits for actionability checks, then scrolls the element into view if needed and uses page.mouse to double click in the center of the element.
If the element is detached from DOM, the method throws an error.
Bear in mind that if the first click of the dblclick()
triggers a navigation event, there will be an exception.
NOTE
elementHandle.dblclick()
dispatches twoclick
events and a singledblclick
event.
#
elementHandle.dispatchEvent(type[, eventInit])type
<string> DOM event type:"click"
,"dragstart"
, etc.eventInit
<Object> event-specific initialization properties.- returns: <Promise>
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:
#
elementHandle.fill(value[, options])value
<string> Value to set for the<input>
,<textarea>
or[contenteditable]

to disable timeout. The default value can be changed by using the browserContext.setDefaultTimeout(timeout) or page.setDefaultTimeout(timeout) methods.
- returns: <Promise>
This method waits for actionability checks, focuses the element, fills it and triggers an input
event after filling.
If the element is not an <input>
, <textarea>
or [contenteditable]
element, this method throws an error.
Note that you can pass an empty string to clear the input field.
#
elementHandle.focus()- returns: <Promise>
Calls focus on the element.
#
elementHandle.getAttribute(name)Returns element attribute value.
#

.
key
can specify the intended keyboardEvent.key value or a single character to generate the text for. A superset of the key
values can be found here. Examples of the keys are:
F1
- F12
, Digit0
- Digit9
, KeyA
- KeyZ
, Backquote
, Minus
, Equal
, Backslash
, Backspace
, Tab
, Delete
, Escape

, PageDown
, PageUp
, ArrowRight
, ArrowUp
, etc.
Following modification shortcuts are also suported: 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.
