Answer 1

find_element_by_id('#clearBrowsingDataConfirm')这句id名字前不用加#的，既然指定了by_id加#号就是多此一举，这会使他找不到这个元素

追问

去掉这个#号还是不行，请帮帮忙

追答

报啥错啊？

追问

和前面的报错信息一样

追答

额 配置了下开发环境，研究了一下；发现我解决不了，这个谷歌浏览器的设置页面使用了Shadow-dom 是游离在 DOM 树之外的节点树，但是他的创建基于普通 DOM 元素（非 document）

使用selenium根本无法取到#shadow-root (open)内部元素

这个链接看下是否对你有帮助猿问

谢谢你的回答，看来在我能力范围之外，想其他办法吧。
