作者：我爱喝可乐
本文给大家分享jQuery EasyUI编辑DataGrid用combobox实现多级联动效果的实例代码，代码简单易懂，非常不错，具有参考借鉴价值，感兴趣的朋友一起看看吧
我在项目中设计课程表的时候需要用到老师和分类之间的多级联动。
首先是一张效果图：
下面是实现的代码：
<body>
<script type="text/javascript">
$(function(){
var editing ; //判断用户是否处于编辑状态
var flag ; //判断新增和修改方法
$('#set_schedule').datagrid({
idField:'id' ,

striped: true ,
loadMsg: '数据正在加载,请耐心的等待...' ,
