这个方法如果是对于下面的三级树的话可以拿到爷爷Id，自己Id，父亲Id；其实如果想要拿到label的话就把data.id换成data.label就行了

function treeFindPath(tree, func, path = []) {
        if (!tree) return []
        for (const data of tree) {
          path.push(data.id)
          if (func(data)) return path
          if (data.children) {
            const findChildren = treeFindPath(data.children, func, path)
            if (findChildren.length) return findChildren
          }
          path.pop()
        }
        return []
      }
      const i = treeFindPath(this.treeData, node => node.label === result)

比如树结构是这样的：这相当于是多可三级树
