Answer 1

I am posting here my function just in case other will look and will want to get it straight forward no need for jquery native JS. Because I was looking for the same thing and finally made this function after viewing others answers:

function queryStringToJSON(queryString) {
  if(queryString.indexOf('?') > -1){
    queryString = queryString.split('?')[1];
  }
  var pairs = queryString.split('&');
  var result = {};
  pairs.forEach(function(pair) {
    pair = pair.split('=');
    result[pair[0]] = decodeURIComponent(pair[1] || '');
  });
  return result;
}


console.log(queryStringToJSON(window.location.href)); 
console.log(queryStringToJSON('test=1&check=wow'));//Object {test: "1", check: "wow"}
