How to get "GET" variables from request in JavaScript?
Does jQuery ou YUI! has this feature built-in?

A:
You can parse the URL of the current page to obtain the GET parameters. The URL can be found by using location.href.

Note that this isn't entirely reliable, as the server may have redirected you elsewhere. But it's the best you can do.

A:
You can use the URL to acquire the GET variables. In particular, window.location.search gives everything after (and including) the '?'. You can read more about window.location here.

A:
All data is available under
window.location.search
you have to parse the string, eg.
function get(name){
if(name=(new RegExp('[?&]'+encodeURIComponent(name)+'=([^&]*)')).exec(location.search))
return decodeURIComponent(name[1]);
}
just call the function with GET variable name as parameter, eg.
get('foo');
this function will return the variables value or undefined if variable has no value or doesn't exist

@Daniel Silveira: yes, it could/should decode the value (and encode the name). Will edit my post in few moments

Note that decodeURIComponent does not decode /all/ possible URI escapes. In particular "+" won't be decoded as " ". (I forget which browser this was in. FF, maybe?) The spec requires them to only decode exactly what encodeUIRComponent encodes, and it will encode " " as "%20", so "+" is left alone.

If you already use jquery there is a jquery plugin that handles this:
