JS in document. The difference between URL and Windows.location.href

In fact, the difference between the two objects, document and Windows, already contains the answer to this question.

Documents represents a Document object, and Windows represents a Window object.
There can be a lot of document objects under a window. Each document has a URL.
But that's not all the difference. When you CTRL + F5 a link http://www.jb51.net/#server
Print alert (document. URL); and alert (WINDOWS.LOCATION.HREF);
found that the values of these two are different,
Document. url:http://www.jb51.net/
windows.location.href:http://www.jb51.net/#server
Therefore, if you want to use fragment for the corresponding treatment, it is best to use Windows.location.href
Otherwise, there will be a strange mistake.
