selenium webdriver报错Element is no longer valid是什么原因？

巴黎的灯光下

1. In your case, you clicked a button, found the element and then page changed due to the previous click action. Thus you got "Element is not valid".
   
2. This might help: wait for page load in selenium

大概就是在点击按钮之后，页面还没有来得及刷新或者跳转，就有执行了一次点击。解决方法：在两次点击中间加一定的等待时间。
