我在页面中有一个注销"按钮.我正在尝试在Selenium中使其自动化.以下是该元素的源代码.

I have a LogOut button in a page. I am trying to automate it in Selenium.Following is the source code for that element.

但是我反复得到No Such Elemet found异常，有时是Invalid Selector Exception.有人可以帮我吗?

But i am repeatedly getting No Such Elemet found exception and sometimes Invalid Selector Exception. Could somebody please help me with this ?

推荐答案

您将获得InvalidSelectorException，因为您无法使用cssSelector来基于其内部HTML文本查找元素.为此，您可以使用xpath或linkText选择器.

You are getting InvalidSelectorException because you can't use cssSelector to find element based on it's inner HTML text. For that you could use xpath or linkText selectors.

xpath:driver.findElement(By.xpath(".//a[text()='Log Out']");

linkText:driver.findElement(By.linkText("Log Out"));

linkText: driver.findElement(By.linkText("Log Out"));

NoSuchElement异常可能是由于您像@gecki所说的那样在类选择器中省略了_而抛出的，所以您的选择器正在搜索不存在的类.

NoSuchElement exception was probably thrown because you left out _ in class selector as @gecki said so your selector was searching for class which doesn't exist.
