Replacing %20, %40 etc

Getting variables from a url

[madmatt69]

Hey all,

I'm using this great script that helps me retrieve variables from a URL:

function gup( name )
{
 name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
 var regexS = "[\\?&]"+name+"=([^&#]*)";
 var regex = new RegExp( regexS );
 
 var results = regex.exec( window.location.href );
 if( results == null )
  return "";
 else
  return results[1];
}
var name = gup( 'name' );
var mail = gup( 'from' );

It works well, however in the variables there are spaces and the '@' sign.

I've looked into some tutorials to try and figure this out, but I just can't seem to get it right.

How can I get it to loop through and replace %20 with spaces, and %40 with @?

It sounds as if you need to unescape() the URL first in order to decode the hexidecimal escape sequences....

var results = regex.exec( unescape(window.location.href) );

Wow - I had written like 4 other variables manually changing the characters.

unescape makes it so much easier :) thanks!
