参考element的树形控件

代码实现

<el-tree :data="treeData" show-checkbox @check-change="selectTreeNode" :check-strictly="true" node-key="id"
 :default-expand-all="true" :props="defaultProps" highlight-current @node-click="handleNodeClick" ref="tree">
</el-tree>
/** 选择树节点 */
selectTreeNode(data, checked, tree) {
    if (checked) {
           this.currentNode = data;
           this.$refs.tree.setCheckedNodes([data]);
            }
        },
