easyui의 DataGrid 컴포넌트를 사용할 때 쿼리 중에 전달되는 쿼리 매개변수는 편의상 jquery의 직렬화 메서드를 확장했습니다. 이 메서드를 호출하면 양식의 모든 데이터를 직렬화할 수 있습니다

$.fn.serializeObject=function(){
  var obj=new Object();
  $.each(this.serializeArray(),function(index,param){
    if(!(param.name in obj)){
      obj[param.name]=param.value;
    }
  });
  return obj;
};
