扩展jQuery easyui form插件的三个方法

 1 $.extend($.fn.form.methods, {  
 2     serialize: function(jq){  
 3         var arrayValue = $(jq[0]).serializeArray();
 4         var json = {};
 5         $.each(arrayValue, function() {
 6             var item = this;
 7             if (json[item["name"]]) {
 8                 json[item["name"]] = json[item["name"]] + "," + item["value"];
 9             } else {
10                 json[item["name"]] = item["value"];
11             }
12         });
13         return json; 
14     },
15     getValue:function(jq,name){  
16         var jsonValue = $(jq[0]).form("serialize");
17         return jsonValue[name]; 
18     },
19     setValue:function(jq,name,value){
20         return jq.each(function () {
21                 _b(this, _29);
22                 var data = {};
23                 data[name] = value;
24                 $(this).form("load",data);
25         });
26     }
27 });  

1 $('form').form('serialize');
2 
3 $('form').form('getValue','a'); //获取表单中name=a 的元素值
4 
5 $('form').form('setValue',{'name':'a'}); //赋值给表单中name=a 的元素值
