Jquery Easy-UI 树形菜单的运用

一、树形菜单的右键标签

     期中增加同级机构、增加下属机构、修改、删除分别是调用了addNode(),del()等方法。

<div id="menuTree" class="easyui-menu" style="width: 120px;">
        <SecurityTag:Authorize ID="Authorize12" runat="server" FunctionID="fun_AddSiblingOrg">
            <div id="miAddSibling" onclick="addNode(1)" data-options="iconCls:‘icon-add‘">
                新增同级机构</div>
        </SecurityTag:Authorize>
        <SecurityTag:Authorize ID="Authorize1" runat="server" FunctionID="fun_AddChildrenOrg">

            <div class="menu-sep">
            </div>
            <div id="miDel" onclick="del()" data-options="iconCls:‘icon-no‘">
                删除</div>
        </SecurityTag:Authorize>
    </div>

    至于为什么右键点击才显示,那就是easyui的内容了,不过有一点注意,加入权限管理标签方便后面对这些按钮权限的控制,这里也可以当作不用加入这些标签,<div class="menu-sep"></div>是增加分割线,

下面就是要在js中处理了。
