两者有什么区别 ：
location.replace(url)
和
location.href = url
我读到第一种方法刺激HTTP重定向,第二种方法类似,通过单击链接来跟踪网页.
但我真的不明白,这是什么意思.
解决方法
location.replace不会更新浏览器的历史记录,你不能按后退按钮,location.href就像点击链接一样.
The Location.replace()method replaces the current resource with the
one at the provided URL. The difference from the assign() method is
that after using replace() the current page will not be saved in
session History,meaning the user won’t be able to use the back button
to navigate to it.
