echarts树使用案例

在树节点中右键点击.

<ul class="menu right-click-menu nav nav-pills nav-stacked">
            <li><a id="menuUpdate" href="#">修改</a></li>
            <li><a id="menuInsert" href="#">新增</a></li>
            <li><a id="menuDelete" href="#">删除</a></li>
            <li><a id="menuRisk" href="#">风险缓解</a></li>
        </ul>
