jquery easyui无法绑定下拉框内容
最近在研究jquery easyui的DataGrid，发现DataGrid中的下拉框无法绑定值，找了很久也没发现是具体问题所在，最后还是同事帮忙搞定的。具体问题竟然是jquery easyui提供的demo中的jquery版本有问题，还有就是绑定的json数据源要添加Method: "get"属性，要不然在C#中会有问题。
具体代码如下：
<link rel="stylesheet" type="text/css"
href="themes/default/easyui.css" />
<link rel="stylesheet" type="text/css"
href="themes/icon.css" />
<link rel="stylesheet" type="text/css"
href="css/demo.css" />
<script type="text/javascript"
src="jquery/jquery-1.8.0.min.js"></script>
<script type="text/javascript"
src="jquery/jquery.easyui.min.js"></script>
<body>
<h2>
Haven't finished tasks</h2>
<div class="demo-info">
<div class="demo-tip icon-tip">

<div>

editing.</div>
</div>
<div style="margin: 10px 0;">
</div>
<table id="dg" class="easyui-datagrid"
title="Haven't finished tasks" style="width: 1000px;
