It is very convenient to use document.referrer to go back to the source page (also known as the previous page), we do not need to know the complex url of the source page, and the document.referrer will be reloaded when it comes back to the source page, rather than the previous state.

But in IE, use javascript to jump, such as _ window.location.href= "; HTTP referrer,IE browsers that can't get the browser request will report a script error" deny access "because IE empties the document.referrer.

Other major browsers Firefox and Chrome will retain referrer, which means that IE will enjoy the "ministerial" special treatment again:

The copy code is as follows:

Var referLink = document.createElement ('a')

ReferLink.href = url

Document.body.appendChild (referLink)

ReferLink.click ()
