你还是没看懂1#的意思。
代码得格式化，看起来才不会别扭。例如：这是HTML代码
同感，表达不够清楚。所以我们都帮不上忙啊!难道你是想把select改成多选？
现在效果是单选，要能多选的~~~
就是执行人和上面对应的$(function(){
$('#userb_username').combogrid({
});方法实现
现在经修改成
<select name="executor" class="easyui-combobox"  id="executor" valueField="text" textField="text" multiple="true" url="http://localhost:8080/testhall/hall/userb/userbForCombobox"></select>
可以进行多选，添加进数据库也没问题，但是当点击修改时多选的地方每个字段之间都会加一个","，请问怎么搞定~~~~~~
