Simple implementation of jQuery serializing forms into objects

When using easyui's datagrid component, the query parameters passed during the query are object types. For convenience, the serialization method in jquery has been extended. By calling this method, all data in the form can be serialized

$.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;
};

Specific use: 

<%@ page language="java" contentType="text/html; charset=UTF-8"
  pageEncoding="UTF-8"%>
<%@include file="/WEB-INF/views/inc/taglibs.jsp"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<jsp:include page="/WEB-INF/views/inc/meta.jsp"></jsp:include>

<script type="text/javascript">
/* 将form表单序列化成对象object*/
$.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;
};
 
$(function() {
    query();
});
 
function query() {
    var params=$(&#39;#queryForm&#39;).serializeObject();
    //{username:$(&#39;#username&#39;).val()}
