调试易

是菜单项哦，不是menubutton，别理解错了。    <!-- 弹出菜单 -->
<div id="mm" class="easyui-menu" style="width:160px;">
    <div iconCls="icon-properties" onclick="javascript:alert('new')">基本设定</div>
    <div class="menu-sep"></div>
    <div iconCls="icon-users" onclick="javascript:alert('new')">查看人员</div>
    <div class="menu-sep"></div>
    <div onclick="javascript:alert('new')">前提条件</div>
    <div onclick="javascript:alert('new')">条件流转</div>
    <div onclick="javascript:alert('new')">权限设置</div>
    <div class="menu-sep"></div>
    <div iconCls="icon-add" onclick="javascript:alert('new')">添加串联节点</div>
    <div iconCls="icon-insert" onclick="javascript:alert('new')">插入串联节点</div>
    <div onclick="javascript:alert('new')">添加并联节点</div>
    <div class="menu-sep"></div>
    <div iconCls="icon-del" onclick="javascript:alert('new')" disabled="true">删除此关</div>
</div>
在html中直接加disabled属性是可以的，但是用js代码如何做呢？
