Editable DataGrid 实现列表新增编辑功能

今天在开发一个功能时候，需要直接在列表实现新增、编辑等功能。于是查看easyui 相关文档，找到相关解决办法。

easyui的datagrid支持可编辑功能。它使用户能够向数据网格中添加一个新行。用户也可以更新一个或多个行。

下面是我在项目中的实现代码：

第一步：引用

      easyui.css

      jquery-1.8.1.min.js

      jquery.easyui.min.js

第二步：Html和Javascript代码

    <h2>Editable DataGrid Demo</h2>
    <div class="demo-info">
        <div class="demo-tip icon-tip">&nbsp;</div>
        <div>Click the edit button on the right side of row to start editing.</div>
    </div>
    
    <div style="margin:10px 0">
        <a href="javascript:void(0)" class="easyui-linkbutton" onclick="insert()">Insert Row</a>
    </div>
    
    <table id="tt"></table>
    
    <script>
        var products = [
            {productid:'FI-SW-01',name:'Koi'},
            {productid:'K9-DL-01',name:'Dalmation'},
            {productid:'RP-SN-01',name:'Rattlesnake'},
            {productid:'RP-LI-02',name:'Iguana'},
            {productid:'FL-DSH-01',name:'Manx'},
            {productid:'FL-DLH-02',name:'Persian'},
            {productid:'AV-CB-01',name:'Amazon Parrot'}
        ];
        $(function(){
            $('#tt').datagrid({
