JSON.stringify 過濾字段

 

let obj = {name: 'lili', age: 21, children: [{name: 'lucy', age: 18}]}
let str = JSON.stringify(obj, ["name", "children"])

console.log(str) // '{"name":"lili","children":[{"name":"lucy"}]}'
// 很有用，並且很方便，自動遞歸

也可以替換

const obj = JSON.parse(

        JSON.stringify(resData)

          .replace(/"subList":/g, '"children":')

          .replace(/"id":/g, '"value":')

          .replace(/"name":/g, '"label":'),

      );
