    Javascript: Get URL Variables

    <script type="text/javascript">
    // Read a page's GET URL variables and return them as an associative array.
    function getUrlVars() {
      var vars = [], hash;
      var hashes = window.location.href.slice(window.location.href.indexOf(’?') + 1).split(’&’);
      for(var i = 0; i < hashes.length; i++) {
        hash = hashes[i].split(’=');
        vars.push(hash[0]);
        vars[hash[0]] = hash[1];
      }
      return vars;
    }
    // Example for URL http://www.example.com/index.html?hello=bonjour&goodevening=bonsoir
    var hash = getUrlVars();
    // alert(hash['hello']); // prints ‘bonjour’
    // alert(hash['goodevening']); // prints ‘bonsoir’
    </script>
