推荐答案

HTML来源可能会帮助我更好地进行分析.但是，您还可以在切换到特定的框架或窗口后使用getpagesource()函数调试代码，以检查其是否正确切换到页面，并查看元素是否在要切换到的页面中可用.

HTML source might help me better to analyze. However, you can also debug the code by using getpagesource() function after switching to particular frame or window to check if it's properly switching to the page and see if the element is available in the page you are switching to.
