There is no native solution that I'm aware of. Dojo has a built-in unserialization method if you use that framework by chance.

Otherwise you can implement it yourself rather simply:

function unserialize(str) {
  str = decodeURIComponent(str);
  var chunks = str.split('&'),
      obj = {};
  for(var c=0; c < chunks.length; c++) {
    var split = chunks[c].split('=', 2);
    obj[split[0]] = split[1];
  }
  return obj;
}

edit: added decodeURIComponent()
