51工具盒子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' ,
fitColumns: false ,

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

{field:'ck' , checkbox:true}
]],
