所以我在使用 selenium 单击 HTML 中隐藏的导航栏时遇到问题...我需要单击操作按钮，然后单击导出 (Excel)。

目前，我将其设置为 aria-labeledby=share，这假设我想单击导出 (CSV) 并执行任务(当脚本想要工作时……如果不是，则会出现以下错误)。当我尝试设置 find_elements_by_css_selector() 或 find_elements_by_xpath() 并将其指向 Export(Excel) 时，它不起作用。所以我目前将它设置为 aria-labeledby=Share 并且这有效但随机它会停止工作并且我会收到以下错误。在检查网页元素之前，我从未听说过将 WAI-Aria 嵌入到 HTML 中。

action = ActionChains(driver)

aria_lablededBy = driver.find_elements_by_css_selector("[aria-labeledby=Actions]")[0]

action.move_to_element(aria_lablededBy).click(aria_lablededBy).perform()

share = driver.find_elements_by_css_selector('[aria-labeledby=Share]')[0]

action.move_to_element(share).click(share).perform()

上面的代码工作然后随机停止，我得到这个错误消息

ERROR:

我正在连接的 HTML 站点有 Aria-HTML 代码，我对此并不熟悉。我删除了共享变量和共享变量上的以下操作，脚本将打开操作导航...一旦启用共享变量和操作，它就会给我错误

我在这个问题上出类拔萃，所以如果社区中有人知道如何解决这个问题，我非常感兴趣。

完整的 HTML - 当 Action 被隐藏时 enter image description here您会看到第二个方 block 包含有关下拉菜单的信息，并且位于 Nav 部分下方

完整的 HTML - 当操作可见时 enter image description here

一旦您点击操作，DIV 容器就会移出 Nav 部分，现在是 Body 部分的一部分

最佳答案

这个错误信息...

selenium.common.exceptions.JavascriptException: Message: javascript error: Failed to execute 'elementsFromPoint' on 'Document': The provided double value is non-finite.

...暗示WebDriver实例无法使用 Locator Strategy 找到所需的元素出于一个或另一个原因:

  • 定位器策略 未在 DOM Tree 中唯一标识所需元素.

  • 当您尝试使用以下行与其进行交互时，该元素不是可交互:

    action.move_to_element(share).click(share).perform()

  • 元素在 <iframe> 中/<frame>

  • 元素的style属性包含 display: none;

  • 元素在 shadow DOM 中.

分析

相关的 HTML 将有助于以更好的方式分析问题。但是，您需要注意以下几件事:

  • 确保定位器策略在 HTML DOM 中唯一标识所需元素.

  • 诱导 WebDriverWait对于 visibility_of_all_elements_located()您可以使用以下 Locator Strategy :

    share = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "span.movie-rating-summary>span")))[0]
    ActionChains(driver).move_to_element(share).click(share).perform()

You can find a relevant detailed discussion in Is it possible to switch to an element in a frame without using driver.switchTo().frame(“frameName”) in Selenium Webdriver Java?
