parse the query string of a URL and return an object

parseQuery.js

function parseQuery(){
  var query = {};
  var temp = window.location.search.substring(1).split('&');
  for (var i = temp.length; i--;) {
    var q = temp[i].split('=');
    query[q.shift()] = q.join('=');
  }
  return query;
}

This function will not unescape strings. To do so, use this line:

query[q.shift()] = unescape(q.join('='));

To also unescape query keys, use this line:

query[unescape(q.shift())] = unescape(q.join('='));

Unescaped keys with spaces will not be accessible through the dot operator -- query.thing -- and will instead need to be accessed by index -- query["multiword thing"].
