el-tree 節點常用操作

    <el-tree   ref="tree" > </el-tree>

通過key獲取節點

   let selectNode = this.$refs.tree.getNode(this.currentData.targetId);
      console.log(selectNode);
      console.log(selectNode.parent);

節點下追加節點

       this.$refs.tree.append(appendNode, fatherNode);

移除節點

 this.$refs.tree.remove(this.currentNode);
