获取el-tree所有层级的id

点击到树的某一级，官方事件只返回了最后一级的id,如何获取整个点击路径的id

findPath(node, targetId, path = []) {
      if (node.dept_id === targetId) {
        path.push(node.dept_id);
        return true;
      }
      if (node.children && node.children.length > 0) {
        for (let child of node.children) {
          if (this.findPath(child, targetId, path)) {
            path.push(node.dept_id);
            return true;
          }
        }
      }
      return false;
    },
    getPathToRoot(tree, targetId) {
    // 辅助函数，递归遍历树形结构
      let path = [];
      for (let node of tree) {
        if (this.findPath(node, targetId, path)) {
          break;
        }
      }
      return path.reverse();
    },
 handleNodeClick(nodeData){
      let nodeIds = []; // 存储节点的 id
      nodeIds = this.getPathToRoot(this.departmentList, nodeData.dept_id);
    },
