ElementHandle

ElementHandle 代表页面中的一个 DOM 元素。可以通过 page.query_selector() 方法创建 ElementHandle。

不推荐

不推荐使用 ElementHandle,请使用 Locator 对象和 web-first 断言替代。

href_element = page.query_selector("a")
href_element.click()

ElementHandle 会阻止 DOM 元素被垃圾回收,除非通过 js_handle.dispose() 方法释放句柄。当其所属的 frame 被导航时,ElementHandle 会自动释放。

ElementHandle 实例可以作为参数传递给 page.eval_on_selector()page.evaluate() 方法。

Locator 和 ElementHandle 的区别在于,ElementHandle 指向某一个具体的元素,而 Locator 则封装了如何获取元素的逻辑。

在下面的例子中,handle 指向页面上的某个具体 DOM 元素。如果该元素的文本发生变化,或者被 React 用于渲染完全不同的组件,handle 依然指向原来的那个 DOM 元素。这可能导致一些意外行为。

handle = page.query_selector("text=Submit")
handle.hover()
handle.click()

使用 locator 时,每次使用 element,都会根据选择器在页面中查找最新的 DOM 元素。因此在下面的代码片段中,底层的 DOM 元素会被查找两次。

locator = page.get_by_text("Submit")
locator.hover()
locator.click()

方法

bounding_box

v1.9 之前添加 elementHandle.bounding_box

此方法返回元素的边界框(bounding box),如果元素不可见则返回 null。边界框是相对于主 frame 视口计算的——通常与浏览器窗口一致。

滚动会影响返回的边界框,类似于 Element.getBoundingClientRect。这意味着 x 和/或 y 可能为负数。

来自子 frame 的元素返回的是相对于主 frame 的边界框,不同于 Element.getBoundingClientRect

假设页面是静态的,可以安全地使用边界框坐标进行输入。例如,下面的代码片段会点击元素的中心。

用法

box = element_handle.bounding_box()
page.mouse.click(box["x"] + box["width"] / 2, box["y"] + box["height"] / 2)

返回值

  • NoneType | Dict#
    • x float

      元素的 x 坐标(像素)。

    • y float

      元素的 y 坐标(像素)。

    • width float

      元素的宽度(像素)。

    • height float

      元素的高度(像素)。


content_frame

v1.9 之前添加 elementHandle.content_frame

如果元素句柄引用的是 iframe 节点,则返回其内容 frame,否则返回 null

用法

element_handle.content_frame()

返回值


owner_frame

v1.9 之前添加 elementHandle.owner_frame

返回包含该元素的 frame。

用法

element_handle.owner_frame()

返回值


wait_for_element_state

v1.9 之前添加 elementHandle.wait_for_element_state

当元素满足指定的 state 时返回。

根据 state 参数,此方法会等待通过某个 可操作性 检查。如果等待过程中元素被移除,则会抛出异常,除非等待的是 "hidden" 状态。

  • "visible" 等待元素 可见
  • "hidden" 等待元素 不可见 或未挂载。注意等待 hidden 时元素被移除不会抛出异常。
  • "stable" 等待元素既 可见稳定
  • "enabled" 等待元素 可用
  • "disabled" 等待元素 不可用
  • "editable" 等待元素 可编辑

如果元素在 timeout 毫秒内未满足条件,则此方法会抛出异常。

用法

element_handle.wait_for_element_state(state)
element_handle.wait_for_element_state(state, **kwargs)

参数

返回值


Deprecated

check

Added before v1.9 elementHandle.check
Discouraged

Use locator-based locator.check() instead. Read more about locators.

This method checks the element by performing the following steps:

  1. Ensure that element is a checkbox or a radio input. If not, this method throws. If the element is already checked, this method returns immediately.
  2. Wait for actionability checks on the element, unless force option is set.
  3. Scroll the element into view if needed.
  4. Use page.mouse to click in the center of the element.
  5. Ensure that the element is now checked. If not, this method throws.

If the element is detached from the DOM at any moment during the action, this method throws.

When all steps combined have not finished during the specified timeout, this method throws a TimeoutError. Passing zero timeout disables this.

Usage

element_handle.check()
element_handle.check(**kwargs)

Arguments

  • force bool (optional)#

    Whether to bypass the actionability checks. Defaults to false.

  • no_wait_after bool (optional)#

    Deprecated

    This option has no effect.

    This option has no effect.

  • position Dict (optional) Added in: v1.11#

    A point to use relative to the top-left corner of element padding box. If not specified, uses some visible point of the element.

  • timeout float (optional)#

    Maximum time in milliseconds. Defaults to 30000 (30 seconds). Pass 0 to disable timeout. The default value can be changed by using the browser_context.set_default_timeout() or page.set_default_timeout() methods.

  • trial bool (optional) Added in: v1.11#

    When set, this method only performs the actionability checks and skips the action. Defaults to false. Useful to wait until the element is ready for the action without performing it.

Returns


click

Added before v1.9 elementHandle.click
Discouraged

Use locator-based locator.click() instead. Read more about locators.

This method clicks the element by performing the following steps:

  2. Scroll the element into view if needed.
  3. Use page.mouse to click in the center of the element, or the specified position.
  4. Wait for initiated navigations to either succeed or fail, unless no_wait_after option is set.

If the element is detached from the DOM at any moment during the action, this method throws.

When all steps combined have not finished during the specified timeout, this method throws a TimeoutError. Passing zero timeout disables this.

Usage

element_handle.click()
element_handle.click(**kwargs)

Arguments

  • no_wait_after bool (optional)#

    Deprecated

    This option will default to true in the future.

    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 to false.

dispatch_event

Added before v1.9 elementHandle.dispatch_event
Discouraged

Use locator-based locator.dispatch_event() instead. Read more about locators.

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().

Usage

element_handle.dispatch_event("click")

Under the hood, it creates an instance of an event based on the given type, initializes it with event_init properties and dispatches it on the element. Events are composed, cancelable and bubble by default.

Since event_init 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:

# note you can only create data_transfer in chromium and firefox
data_transfer = page.evaluate_handle("new DataTransfer()")
element_handle.dispatch_event("#source", "dragstart", {"dataTransfer": data_transfer})

Arguments

  • type str#

    DOM event type: "click", "dragstart", etc.

  • event_init EvaluationArgument (optional)#

    Optional event-specific initialization properties.

Returns


eval_on_selector

Added in: v1.9 elementHandle.eval_on_selector
Discouraged

This method does not wait for the element to pass actionability checks and therefore can lead to the flaky tests. Use locator.evaluate(), other Locator helper methods or web-first assertions instead.

Returns the return value of expression.

The method finds an element matching the specified selector in the ElementHandles subtree and passes it as a first argument to expression. If no elements match the selector, the method throws an error.

If expression returns a Promise, then element_handle.eval_on_selector() would wait for the promise to resolve and return its value.

Usage

tweet_handle = page.query_selector(".tweet")
assert tweet_handle.eval_on_selector(".like", "node => node.innerText") == "100"
assert tweet_handle.eval_on_selector(".retweets", "node => node.innerText") == "10"

Arguments

  • selector str#

    A selector to query for.

  • expression str#

    JavaScript expression to be evaluated in the browser context. If the expression evaluates to a function, the function is automatically invoked.

  • arg EvaluationArgument (optional)#

    Optional argument to pass to expression.

Returns


eval_on_selector_all

Added in: v1.9 elementHandle.eval_on_selector_all
Discouraged

In most cases, locator.evaluate_all(), other Locator helper methods and web-first assertions do a better job.

Returns the return value of expression.

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 expression.

If expression returns a Promise, then element_handle.eval_on_selector_all() would wait for the promise to resolve and return its value.

Usage

<div class="feed">
<div class="tweet">Hello!</div>
<div class="tweet">Hi!</div>
</div>
feed_handle = page.query_selector(".feed")
assert feed_handle.eval_on_selector_all(".tweet", "nodes => nodes.map(n => n.innerText)") == ["hello!", "hi!"]

Arguments

  • selector str#

    A selector to query for.

  • expression str#

    JavaScript expression to be evaluated in the browser context. If the expression evaluates to a function, the function is automatically invoked.

  • arg EvaluationArgument (optional)#

    Optional argument to pass to expression.

Returns


fill

Added before v1.9 elementHandle.fill
Discouraged

Use locator-based locator.fill() instead. Read more about locators.

This method waits for actionability 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, the control will be filled instead.

To send fine-grained keyboard events, use locator.press_sequentially().

Usage

    The quality of the image, between 0-100. Not applicable to png images.

  • scale "css" | "device" (optional)#

    When set to "css", screenshot will have a single pixel per each css pixel on the page. For high-dpi devices, this will keep screenshots small. Using "device" option will produce a single pixel per each device pixel, so screenshots of high-dpi devices will be twice as large or even larger.

    Defaults to "device".

  • style str (optional) Added in: v1.41#

    Text of the stylesheet to apply while making the screenshot. This is where you can hide dynamic elements, make elements invisible or change their properties to help you creating repeatable screenshots. This stylesheet pierces the Shadow DOM and applies to the inner frames.

    Maximum time in milliseconds. Defaults to 30000 (30 seconds). Pass 0 to disable timeout. The default value can be changed by using the browser_context.set_default_timeout() or page.set_default_timeout() methods.

  • trial bool (optional)#

    When set, this method only performs the actionability checks and skips the action. Defaults to false. Useful to wait until the element is ready for the action without performing it.

Returns


set_input_files

Added before v1.9 elementHandle.set_input_files
Discouraged

Use locator-based locator.set_input_files() instead. Read more about locators.

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. For inputs with a [webkitdirectory] attribute, only a single directory path is supported.

This method expects ElementHandle to point to an input element. However, if the element is inside the <label> element that has an associated control, targets the control instead.

Usage

element_handle.set_input_files(files)
element_handle.set_input_files(files, **kwargs)

Arguments

Returns


tap

Added before v1.9 elementHandle.tap
Discouraged

Use locator-based locator.tap() instead. Read more about locators.

This method taps the element by performing the following steps:

  1. Wait for actionability checks on the element, unless force option is set.
  2. Scroll the element into view if needed.
  3. Use page.touchscreen to tap the center of the element, or the specified position.

If the element is detached from the DOM at any moment during the action, this method throws.

When all steps combined have not finished during the specified timeout, this method throws a TimeoutError. Passing zero timeout disables this.

备注

elementHandle.tap() requires that the hasTouch option of the browser context be set to true.

Usage

element_handle.tap()
element_handle.tap(**kwargs)

Arguments

  • force bool (optional)#

    Whether to bypass the actionability checks. Defaults to false.

  • modifiers List["Alt" | "Control" | "ControlOrMeta" | "Meta" | "Shift"] (optional)#

    Modifier keys to press. Ensures that only these modifiers are pressed during the operation, and then restores current modifiers back. If not specified, currently pressed modifiers are used. "ControlOrMeta" resolves to "Control" on Windows and Linux and to "Meta" on macOS.

  • no_wait_after bool (optional)#

    Deprecated

    This option has no effect.

    This option has no effect.

  • position Dict (optional)#

    A point to use relative to the top-left corner of element padding box. If not specified, uses some visible point of the element.

  • timeout float (optional)#

    Maximum time in milliseconds. Defaults to 30000 (30 seconds). Pass 0 to disable timeout. The default value can be changed by using the browser_context.set_default_timeout() or page.set_default_timeout() methods.

  • trial bool (optional) Added in: v1.11#

    When set, this method only performs the actionability checks and skips the action. Defaults to false. Useful to wait until the element is ready for the action without performing it.

Returns


text_content

Added before v1.9 elementHandle.text_content
Discouraged

Use locator-based locator.text_content() instead. Read more about locators.

Returns the node.textContent.

Usage

element_handle.text_content()

Returns


type

Added before v1.9 elementHandle.type
Deprecated

In most cases, you should use locator.fill() instead. You only need to press keys one by one if there is special keyboard handling on the page - in this case use locator.press_sequentially().

Focuses the element, and then sends a keydown, keypress/input, and keyup event for each character in the text.

To press a special key, like Control or ArrowDown, use element_handle.press().

Usage

Arguments

  • text str#

    A text to type into a focused element.

  • delay float (optional)#

    Time to wait between key presses in milliseconds. Defaults to 0.

  • no_wait_after bool (optional)#

    Deprecated

    This option has no effect.

    This option has no effect.

  • timeout float (optional)#

    Maximum time in milliseconds. Defaults to 30000 (30 seconds). Pass 0 to disable timeout. The default value can be changed by using the browser_context.set_default_timeout() or page.set_default_timeout() methods.

Returns


uncheck

Added before v1.9 elementHandle.uncheck
Discouraged

Use locator-based locator.uncheck() instead. Read more about locators.

This method checks the element by performing the following steps:

  1. Ensure that element is a checkbox or a radio input. If not, this method throws. If the element is already unchecked, this method returns immediately.
  2. Wait for actionability checks on the element, unless force option is set.
  3. Scroll the element into view if needed.
  4. Use page.mouse to click in the center of the element.
  5. Ensure that the element is now unchecked. If not, this method throws.

If the element is detached from the DOM at any moment during the action, this method throws.

When all steps combined have not finished during the specified timeout, this method throws a TimeoutError. Passing zero timeout disables this.

Usage

element_handle.uncheck()
element_handle.uncheck(**kwargs)

Arguments

  • force bool (optional)#

    Whether to bypass the actionability checks. Defaults to false.

  • no_wait_after bool (optional)#

    Deprecated

    This option has no effect.

    This option has no effect.

  • position Dict (optional) Added in: v1.11#

    A point to use relative to the top-left corner of element padding box. If not specified, uses some visible point of the element.

  • timeout float (optional)#

    Maximum time in milliseconds. Defaults to 30000 (30 seconds). Pass 0 to disable timeout. The default value can be changed by using the browser_context.set_default_timeout() or page.set_default_timeout() methods.

  • trial bool (optional) Added in: v1.11#

    When set, this method only performs the actionability checks and skips the action. Defaults to false. Useful to wait until the element is ready for the action without performing it.

Returns


wait_for_selector

Added before v1.9 elementHandle.wait_for_selector
Discouraged

Use web assertions that assert visibility or a locator-based locator.wait_for() instead.

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

Wait for the selector relative to the element handle 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

page.set_content("<div><span></span></div>")
div = page.query_selector("div")
# waiting for the "span" selector relative to the div.
span = div.wait_for_selector("span", state="attached")
备注

This method does not work across navigations, use page.wait_for_selector() instead.

Arguments

  • selector str#

    A selector to query for.

  • state "attached" | "detached" | "visible" | "hidden" (optional)#

    Defaults to 'visible'. Can be either:

    • 'attached' - wait for element to be present in DOM.
    • 'detached' - wait for element to not be present in DOM.
    • 'visible' - wait for element to have non-empty bounding box and no visibility:hidden. Note that element without any content or with display:none has an empty bounding box and is not considered visible.
    • 'hidden' - wait for element to be either detached from DOM, or have an empty bounding box or visibility:hidden. This is opposite to the 'visible' option.
  • strict bool (optional) Added in: v1.15#

    When true, the call requires selector to resolve to a single element. If given selector resolves to more than one element, the call throws an exception.

  • timeout float (optional)#

    Maximum time in milliseconds. Defaults to 30000 (30 seconds). Pass 0 to disable timeout. The default value can be changed by using the browser_context.set_default_timeout() or page.set_default_timeout() methods.

Returns
