扩展jQuery easyui form插件的三个方法

$.extend($.fn.form.methods, {  
    serialize: function(jq){  
        var arrayValue = $(jq[0]).serializeArray();
        var json = {};
        $.each(arrayValue, function() {
            var item = this;
            if (json[item["name"]]) {
                json[item["name"]] = json[item["name"]] + "," + item["value"];
            } else {
                json[item["name"]] = item["value"];
            }
        });
        return json; 
    },
    getValue:function(jq,name){  
        var jsonValue = $(jq[0]).form("serialize");
        return jsonValue[name]; 
    },
    setValue:function(jq,name,value){
        return jq.each(function () {
                _b(this, _29);
                var data = {};
                data[name] = value;
                $(this).form("load",data);
        });
    }
});  

$('form').form('serialize');

$('form').form('getValue','a'); //获取表单中name=a 的元素值

$('form').form('setValue',{'name':'a'}); //赋值给表单中name=a 的元素值
