Port returns the port number of the address, and the general HTTP port number is ' 80 '.

Pathname returns the path name, such as "http://www.a.com/b/c.html", location.pathname = = ' b/c.html '.

Hash returns "#" and later content, such as "http://www.a.com/b/c.html#chapter4", Location.hash = = ' #chapter4 '; if there is no "#" in the address, an empty string is returned.

Search return "?" and later content, such as "http://www.a.com/b/c.asp tutorial? selection=3&jumpto=4", Location.search = = '? selection=3&jumpto= 4 '; If there is no "?" in the address, an empty string is returned.

HREF returns all of the above, that is, return the entire address. How to show it on the browser's address bar is how to return it. If you want a window object to open an address, you can use "Location.href = ' ... '", or you can use "location = ' ... '" to do this.
