小言
Original
330 people have browsed it

1、json属于文本,可以将任何js对象转为json,然后将json传递到服务器

2、所有服务器数据都可以作为json转为js对象

3、我们也可以把数据作为js对象来处理,支持任何语言,不受限制

4、可以实现前后端数据都通过json进行交互

Js转json
  1. const user = {
  2. id:1,
  3. name:'测试',
  4. price:100,
  5. };
  6. console.log(user);
  7. let json = JSON.stringify(user);
  8. console.log(json);

Json转js
  1. let str = `{
  2. "id": 1,
  3. "name": "测试",
  4. "price": 100
  5. }`;
  6. let item = JSON.parse(str);
  7. console.log(item);
