创建js文件 const key = "children"; export function parseJson(arr) { arr = arr.slice(); function toParse(arr) { arr.forEach(function (item) { if (item.Childers && Array.isArray(item.Childers)) { item[key] = item.Childers; toParse(item[key]); } delete item.Childers; }); return arr; } return toParse(arr); } 在需要的地方引入 import { parseJson } from "../../utils/parseJson.js"; 调用 parseJson （tree）
