jQuery script to grab params from URL

getUrlVars.js

  $.extend({
    getUrlVars: function(){
      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;
    },
    getUrlVar: function(name){
      return $.getUrlVars()[name];
    }
  });

// Get object of URL params
var allVars = $.getUrlVars();

// This will grab all keyword params (e.g. http://mydomain.com?keywords=foo)
var keywords = $.getUrlVar('keywords');
