양식 데이터를 JSON 객체로 직렬화하는 jQuery 구현 방법

$("#searchForm").serialize();

(function(window, $) {
  $.fn.serializeJson = function() {
    var serializeObj = {};
    var array = this.serializeArray();
    var str = this.serialize();
    $(array).each(
        function() {
          if (serializeObj[this.name]) {
            if ($.isArray(serializeObj[this.name])) {
              serializeObj[this.name].push(this.value);
            } else {
              serializeObj[this.name] = [
                  serializeObj[this.name], this.value ];
            }
          } else {
            serializeObj[this.name] = this.value;
          }
        });
    return serializeObj;
  };
})(window, jQuery);

console.info($("#searchForm").serializeJson());
