Vue将将后端返回的list数据转化为树结构【array-to-tree】

cnpm i -S array-to-tree

import arrayToTree from "array-to-tree";

    const pidData = [
      { name: "aa", id: "1", pid: null },
      { name: "bb", id: 2, pid: 1 },
      { name: "cc", id: 3, pid: "" },
      { name: "dd", id: 4, pid: 3 },
      { name: "ee", id: 5, pid: "3" },
    ];
    const result = arrayToTree(pidData, {
      parentProperty: "pid",
      customID: "id",
      childrenProperty: "children",
    });
    console.log(result);
