我找不到 XPATH，请拨打 facebook 帮忙

我下载了 XPATH finder 但在 facebook 上它不起作用

Answer 1

上面代码中使用的 XPATH 可能不再适用于 Facebook，因为网站的结构和布局会随时间发生变化。 要在 Facebook 上找到您想要与之交互的元素的当前 XPATH，您可以使用像 Chrome DevTools 这样的工具。 在 Chrome 中打开网站，右键单击要查找的元素 XPATH 和 select “检查”。 DevTools window 将打开，元素将在 HTML 结构中突出显示。 右键单击突出显示的元素和 select “复制”>“复制 XPATH”。 这将为您提供该元素的当前 XPATH，您可以在代码中使用它。
