Maybe you can write a function as follows:

var addParams = function[key, val, url] {
  var arr = url.split['?'];
  if[arr.length == 1] {
    return url + '?' + key + '=' + val;
  }
  else if[arr.length == 2] {
    var params = arr[1].split['&'];
    var p = {};
    var a = [];
    var strarr = [];
    $.each[params, function[index, element] {
      a = element.split['='];
      p[a[0]] = a[1];
      }]
    p[key] = val;
    for[var o in p] {
      strarr.push[o + '=' + p[o]];
    }
    var str = strarr.join['&'];
    return[arr[0] + '?' + str];
  }
}
