How to add parameters to a URL that already contains other parameters and maybe an anchor

Question

I\'m wondering how I can add a new parameter to an existing url. The problem is: the url may also contain an anchor.

For example:

http://www.example         


        

Answer 1

Try this:

location.href = location.href.replace(location.hash, '') + '&x=y' + location.hash

Update

What about this:

var a = document.createElement('a');
a.href = "http://www.example.com?foo=bar#hashme";

var url = a.href.replace(a.hash, '') + '&x=y' + a.hash;

I found out that the location object can be created by an anchor element(from Creating a new Location object in javascript).
