js對象與字符串相互轉換

1. 對象轉為字符串

const obj = {
     id: 0,
     name: '張三',
     age: 12
}
const objToStr = JSON.stringify(obj)
console.log('obj:', obj)
console.log('objToStr:', objToStr)

2. json字符串轉為對象

const str = '{"id":0,"name":"張三","age":12}'
const strToObj = JSON.parse(str)
console.log('str:', str)
console.log('strToObj:', strToObj)
