Small javascript snippet to convert location.search parameters and return them as hash

get_params.js

  /**
  *  Returns location search parameters as hash, so we can
  *  use them more naturally in our javascript. Like...cough... rails :P
  *  
  *  Example url: http://my_domain.ext/?page=products&condition=cheap
  *
  *
  *      var params = get_params();
  *
  *          alert( params['page'] ); // => products
  *
  *          alert( params['condition'] ); // => cheap
  *
  */
  var get_params = function(){
    var params = location.search.substr(1).split("&");
    var obj = {}  
    for (var i=0; i < params.length; i++) {
      obj[params[i].split("=")[0]] = params[i].split("=")[1]
    } 
    return obj;
  }
