Frame

在每个时间点，页面都会通过 page.mainFrame() 和 frame.childFrames() 方法公开其当前的框架树。

¥At every point of time, page exposes its current frame tree via the page.mainFrame() and frame.childFrames() methods.

Frame 对象的生命周期由三个事件控制，在页面对象上调度：

¥Frame object's lifecycle is controlled by three events, dispatched on the page object:

page.on('frameattached') - 当框架附加到页面时触发。框架只能附加到页面一次。

¥page.on('frameattached') - fired when the frame gets attached to the page. A Frame can be attached to the page only once.
page.on('framenavigated') - 当框架提交导航到不同的 URL 时触发。

¥page.on('framenavigated') - fired when the frame commits navigation to a different URL.
page.on('framedetached') - 当框架与页面分离时触发。框架只能从页面分离一次。

¥page.on('framedetached') - fired when the frame gets detached from the page. A Frame can be detached from the page only once.

转储框架树的示例：

¥An example of dumping frame tree:

const { firefox } = require('playwright');  // Or 'chromium' or 'webkit'.

(async () => {
  const browser = await firefox.launch();
  const page = await browser.newPage();
  await page.goto('https://www.google.com/chrome/browser/canary.html');
  dumpFrameTree(page.mainFrame(), '');
  await browser.close();

  function dumpFrameTree(frame, indent) {
    console.log(indent + frame.url());
    for (const child of frame.childFrames())
      dumpFrameTree(child, indent + '  ');
  }
})();

¥Returns

Promise<void>#

evaluate

Added in: v1.8

frame.evaluate

返回 pageFunction 的返回值。

¥Returns the return value of pageFunction.

如果传递给 frame.evaluate() 的函数返回 Promise，那么 frame.evaluate() 将等待 Promise 解析并返回其值。

¥If the function passed to the frame.evaluate() returns a Promise, then frame.evaluate() would wait for the promise to resolve and return its value.

如果传递给 frame.evaluate() 的函数返回非可串行化值，则 frame.evaluate() 返回 undefined。Playwright 还支持传输一些 JSON 无法序列化的附加值：-0、NaN、Infinity、-Infinity。

¥If the function passed to the frame.evaluate() returns a non-Serializable value, then frame.evaluate() returns undefined. Playwright also supports transferring some additional values that are not serializable by JSON: -0, NaN, Infinity, -Infinity.

用法

¥Usage

const result = await frame.evaluate(([x, y]) => {
  return Promise.resolve(x * y);
}, [7, 8]);
console.log(result); // prints "56"

也可以传入字符串而不是函数。

¥A string can also be passed in instead of a function.

console.log(await frame.evaluate('1 + 2')); // prints "3"

ElementHandle 实例可以作为参数传递给 frame.evaluate()：

¥ElementHandle instances can be passed as an argument to the frame.evaluate():

const bodyHandle = await frame.evaluate('document.body');

Added in: v1.8

frame.evaluateHandle

将 pageFunction 的返回值作为 JSHandle 返回。

¥Returns the return value of pageFunction as a JSHandle.

frame.evaluate() 和 frame.evaluateHandle() 之间的唯一区别是 frame.evaluateHandle() 返回 JSHandle。

¥The only difference between frame.evaluate() and frame.evaluateHandle() is that frame.evaluateHandle() returns JSHandle.

如果传递给 frame.evaluateHandle() 的函数返回 Promise，那么 frame.evaluateHandle() 将等待 Promise 解析并返回其值。

¥If the function, passed to the frame.evaluateHandle(), returns a Promise, then frame.evaluateHandle() would wait for the promise to resolve and return its value.

用法

¥Usage

// Handle for the window object
const aWindowHandle = await frame.evaluateHandle(() => Promise.resolve(window));

也可以传入字符串而不是函数。

¥A string can also be passed in instead of a function.

const aHandle = await frame.evaluateHandle('document'); // Handle for the 'document'.

JSHandle 实例可以作为参数传递给 frame.evaluateHandle()：

¥JSHandle instances can be passed as an argument to the frame.evaluateHandle():

const aHandle = await frame.evaluateHandle(() => document.body);

这是 elementHandle.contentFrame() 的逆。请注意，返回的句柄实际上属于父框架。

¥This is an inverse of elementHandle.contentFrame(). Note that returned handle actually belongs to the parent frame.

如果在 frameElement() 返回之前框架已分离，则此方法会引发错误。

¥This method throws an error if the frame has been detached before frameElement() returns.

用法

¥Usage

const frameElement = await frame.frameElement();
const contentFrame = await frameElement.contentFrame();
console.log(frame === contentFrame);  // -> true

¥Returns

Promise<ElementHandle>#

最大操作时间（以毫秒为单位）。默认为 0 - 没有超时。可以通过配置中的 navigationTimeout 选项或使用 browserContext.setDefaultNavigationTimeout()、browserContext.setDefaultTimeout()、page.setDefaultNavigationTimeout() 或 page.setDefaultTimeout() 方法更改默认值。

¥Maximum operation time in milliseconds. Defaults to 0 - no timeout. The default value can be changed via navigationTimeout option in the config, or by using the browserContext.setDefaultNavigationTimeout(), browserContext.setDefaultTimeout(), page.setDefaultNavigationTimeout() or page.setDefaultTimeout() methods.

waitUntil "load"|"domcontentloaded"|"networkidle"|"commit"（可选）#

¥waitUntil "load"|"domcontentloaded"|"networkidle"|"commit" (optional)#

什么时候才认为操作成功，默认为 load。事件可以是：

¥When to consider operation succeeded, defaults to load. Events can be either:
- 'domcontentloaded' - 认为操作在 DOMContentLoaded 事件触发时完成。
  
  ¥'domcontentloaded' - consider operation to be finished when the DOMContentLoaded event is fired.
- 'load' - 认为操作在 load 事件触发时完成。
  
  ¥'load' - consider operation to be finished when the load event is fired.
- 'networkidle' - 不鼓励在至少 500 毫秒内没有网络连接时考虑操作完成。不要使用此方法进行测试，而是依靠网络断言来评估准备情况。
  
  ¥'networkidle' - DISCOURAGED consider operation to be finished when there are no network connections for at least 500 ms. Don't use this method for testing, rely on web assertions to assess readiness instead.
- 'commit' - 当收到网络响应并且文档开始加载时，认为操作完成。

该方法返回一个元素定位器，可用于在此页面/框架上执行操作。定位器在执行操作之前立即解析为元素，因此同一定位器上的一系列操作实际上可以在不同的 DOM 元素上执行。如果这些操作之间的 DOM 结构发生了变化，就会发生这种情况。

¥The method returns an element locator that can be used to perform actions on this page / frame. Locator is resolved to the element immediately before performing an action, so a series of actions on the same locator can in fact be performed on different DOM elements. That would happen if the DOM structure between those actions has changed.

用法

¥Usage

frame.locator(selector);
frame.locator(selector, options);

参数

¥Arguments

selector string #

解析 DOM 元素时使用的选择器。

¥A selector to use when resolving DOM element.

options Object (optional)
- has Locator (optional)#

将方法的结果范围缩小到包含与此相对定位器匹配的元素的结果。例如，具有 text=Playwright 的 article 与 <article><div>Playwright</div></article> 相匹配。

¥Narrows down the results of the method to those which contain elements matching this relative locator. For example, article that has text=Playwright matches <article><div>Playwright</div></article>.

内部定位器必须相对于外部定位器，并且从外部定位器匹配开始查询，而不是从文档根开始。例如，你可以在 <article><content><div>Playwright</div></content></article> 中找到 content，其中包含 div。但是，查找具有 article div 的 content 将会失败，因为内部定位器必须是相对的，并且不应使用 content 之外的任何元素。

¥Inner locator must be relative to the outer locator and is queried starting with the outer locator match, not the document root. For example, you can find content that has div in <article><content><div>Playwright</div></content></article>. However, looking for content that has article div will fail, because the inner locator must be relative and should not use any elements outside the content.

请注意，外部和内部定位器必须属于同一框架。内部定位器不得包含 FrameLocator。

¥Note that outer and inner locators must belong to the same frame. Inner locator must not contain FrameLocators.

hasNot Locator (optional) Added in: v1.33#

匹配不包含与内部定位器匹配的元素的元素。内部定位器是针对外部定位器进行查询的。例如，没有 div 的 article 与 <article><span>Playwright</span></article> 相匹配。

¥Matches elements that do not contain an element that matches an inner locator. Inner locator is queried against the outer one. For example, article that does not have div matches <article><span>Playwright</span></article>.

请注意，外部和内部定位器必须属于同一框架。内部定位器不得包含 FrameLocator。

¥Note that outer and inner locators must belong to the same frame. Inner locator must not contain FrameLocators.

hasNotText string|RegExp (optional) Added in: v1.33#

匹配内部某处（可能在子元素或后代元素中）不包含指定文本的元素。当传递 string 时，匹配不区分大小写并搜索子字符串。

¥Matches elements that do not contain specified text somewhere inside, possibly in a child or a descendant element. When passed a string, matching is case-insensitive and searches for a substring.

hasText string|RegExp (optional)#

匹配内部某处（可能在子元素或后代元素中）包含指定文本的元素。当传递 string 时，匹配不区分大小写并搜索子字符串。例如，"Playwright" 匹配 <article><div>Playwright</div></article>。

¥Matches elements containing specified text somewhere inside, possibly in a child or a descendant element. When passed a string, matching is case-insensitive and searches for a substring. For example, "Playwright" matches <article><div>Playwright</div></article>.

¥A selector to search for an element. If there are multiple elements satisfying the selector, the first will be used.

options Object (optional)
- force boolean (optional)#

是否绕过 actionability 检查。默认为 false。

¥Whether to bypass the actionability checks. Defaults to false.

modifiers Array<"Alt"|"Control"|"Meta"|"Shift"> (optional)#

要按下的修改键。确保在操作期间仅按下这些修饰符，然后恢复当前修饰符。如果未指定，则使用当前按下的修饰符。

¥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.

noWaitAfter boolean (optional)#

position Object (optional)#
- x number
- y number

相对于元素填充框左上角使用的点。如果未指定，则使用元素的一些可见点。

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

strict boolean (optional) Added in: v1.14#

如果为 true，则调用需要选择器解析为单个元素。如果给定的选择器解析为多个元素，则调用会引发异常。

¥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 number (optional)#

trial boolean (optional) Added in: v1.11#

设置后，此方法仅执行 actionability 检查并跳过该操作。默认为 false。等待元素准备好执行操作而不执行该操作很有用。

¥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

Promise<void>#

frame.type

已弃用

在大多数情况下，你应该使用 locator.fill()。如果页面上有特殊的键盘处理，则只需一一按键即可 - 在本例中使用 locator.pressSequentially()。

¥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.pressSequentially().

为文本中的每个字符发送 keydown、keypress/input 和 keyup 事件。frame.type 可用于发送细粒度的键盘事件。要在表单字段中填写值，请使用 frame.fill()。

¥Sends a keydown, keypress/input, and keyup event for each character in the text. frame.type can be used to send fine-grained keyboard events. To fill values in form fields, use frame.fill().

要按特殊键，例如 Control 或 ArrowDown，请使用 keyboard.press()。

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

uncheck

Added in: v1.8

frame.uncheck

灰心

请改用基于定位器的 locator.uncheck()。了解有关 locators 的更多信息。

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

该方法通过执行以下步骤来检查与 selector 匹配的元素：

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

查找与 selector 匹配的元素。如果没有，请等待，直到将匹配的元素附加到 DOM。

¥Find an element matching selector. If there is none, wait until a matching element is attached to the DOM.
确保匹配的元素是复选框或单选输入。如果不是，该方法将抛出异常。如果该元素已取消选中，则此方法立即返回。

¥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.
等待 actionability 检查匹配的元素，除非设置了 force 选项。如果在检查期间该元素被分离，则会重试整个操作。

¥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.
如果需要，将元素滚动到视图中。

¥Scroll the element into view if needed.
使用 page.mouse 单击元素的中心。

¥Use page.mouse to click in the center of the element.
等待启动的导航成功或失败，除非设置了 noWaitAfter 选项。

¥Wait for initiated navigations to either succeed or fail, unless noWaitAfter option is set.
确保该元素现在未被选中。如果不是，该方法将抛出异常。

¥Ensure that the element is now unchecked. If not, this method throws.

当所有组合步骤在指定的 timeout 时间内尚未完成时，此方法将抛出 TimeoutError。传递零超时会禁用此功能。

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

waitForNavigation

Added in: v1.8

frame.waitForNavigation

已弃用

这种方法本质上是有问题的，请使用 frame.waitForURL() 代替。

¥This method is inherently racy, please use frame.waitForURL() instead.

等待框架导航并返回主要资源响应。如果存在多个重定向，导航将使用最后一个重定向的响应进行解析。如果导航到不同的锚点或由于历史 API 使用而导航，则导航将解析为 null。

¥Waits for the 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.

用法

¥Usage

此方法等待框架导航到新的 URL。当你运行将间接导致框架导航的代码时，它非常有用。考虑这个例子：

¥This method waits for the frame to navigate to a new URL. It is useful for when you run code which will indirectly cause the frame to navigate. Consider this example:

// Start waiting for navigation before clicking. Note no await.
const navigationPromise = page.waitForNavigation();
await page.getByText('Navigate after timeout').click();
await navigationPromise;

注意

使用历史 API 更改 URL 被视为导航。

¥Usage of the History API to change the URL is considered a navigation.

参数

¥Arguments

options Object (optional)
- timeout number (optional)#

url string|RegExp|function(URL):boolean (optional)#

waitUntil "load"|"domcontentloaded"|"networkidle"|"commit"（可选）#

¥waitUntil "load"|"domcontentloaded"|"networkidle"|"commit" (optional)#

什么时候才认为操作成功，默认为 load。事件可以是：

¥When to consider operation succeeded, defaults to load. Events can be either:
- 'domcontentloaded' - 认为操作在 DOMContentLoaded 事件触发时完成。
  
  ¥'domcontentloaded' - consider operation to be finished when the DOMContentLoaded event is fired.
- 'load' - 认为操作在 load 事件触发时完成。
  
  ¥'load' - consider operation to be finished when the load event is fired.
- 'networkidle' - 不鼓励在至少 500 毫秒内没有网络连接时考虑操作完成。不要使用此方法进行测试，而是依靠网络断言来评估准备情况。
  
  ¥'networkidle' - DISCOURAGED consider operation to be finished when there are no network connections for at least 500 ms. Don't use this method for testing, rely on web assertions to assess readiness instead.
- 'commit' - 当收到网络响应并且文档开始加载时，认为操作完成。
  
  ¥'commit' - consider operation to be finished when network response is received and the document started loading.

¥Returns

Promise<null|Response>#

waitForSelector

Added in: v1.8

frame.waitForSelector

灰心

请改用断言可见性的 Web 断言或基于定位器的 locator.waitFor()。了解有关 locators 的更多信息。

¥Use web assertions that assert visibility or a locator-based locator.waitFor() instead. Read more about locators.

当选择器指定的元素满足 state 选项时返回。如果等待 hidden 或 detached，则返回 null。

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

注意

Playwright 在执行操作之前自动等待元素准备好。使用 Locator 对象和 Web 优先断言使代码无需等待选择器。

¥Playwright automatically waits for element to be ready before performing an action. Using Locator objects and web-first assertions make the code wait-for-selector-free.

等待 selector 满足 state 选项（从 dom 中出现/消失，或者变得可见/隐藏）。如果在调用方法 selector 时已经满足条件，则该方法将立即返回。如果选择器在 timeout 毫秒内不满足条件，该函数将抛出异常。

¥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.

用法

¥Usage

此方法适用于多种导航：

¥This method works across navigations:

const { chromium } = require('playwright');  // Or 'firefox' or 'webkit'.

(async () => {
  const browser = await chromium.launch();
  const page = await browser.newPage();
  for (const currentURL of ['https://google.com', 'https://bbc.com']) {
    await page.goto(currentURL);
    const element = await page.mainFrame().waitForSelector('img');
    console.log('Loaded image: ' + await element.getAttribute('src'));
  }
  await browser.close();
})();

参数

¥Arguments

selector string #

要查询的选择器。

¥A selector to query for.

options Object (optional)

state "attached"|"detached"|"visible"|"hidden"（可选）#

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

默认为 'visible'。可以是：

¥Defaults to 'visible'. Can be either:
- 'attached' - 等待元素出现在 DOM 中。
  
  ¥'attached' - wait for element to be present in DOM.
- 'detached' - 等待 DOM 中不存在元素。
  
  ¥'detached' - wait for element to not be present in DOM.
- 'visible' - 等待元素具有非空边界框并且没有 visibility:hidden。请注意，没有任何内容或具有 display:none 的元素具有空边界框，并且不被视为可见。
  
  ¥'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' - 等待元素从 DOM 分离，或者有一个空的边界框或 visibility:hidden。这与 'visible' 选项相反。
  
  ¥'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 boolean (optional) Added in: v1.14#

如果为 true，则调用需要选择器解析为单个元素。如果给定的选择器解析为多个元素，则调用会引发异常。

¥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 number (optional)#

¥Returns

Promise<null|ElementHandle>#

waitForTimeout

Added in: v1.8

frame.waitForTimeout

灰心

永远不要在生产中等待超时。等待时间的测试本质上是不稳定的。使用自动等待的 Locator 操作和 Web 断言。

¥Never wait for timeout in production. Tests that wait for time are inherently flaky. Use Locator actions and web assertions that wait automatically.

等待给定的 timeout（以毫秒为单位）。

¥Waits for the given timeout in milliseconds.

请注意，frame.waitForTimeout() 只能用于调试。在生产中使用计时器进行的测试将会很不稳定。使用网络事件、选择器变得可见等信号来代替。

¥Note that frame.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.
