javascript json语句 与 js语句的互转

//var data = "weihexin"
//var data = ["weihexin", 1]
var data = {name:"weihexin", id:1}


var json = JSON.stringify(data);//返回 json string
console.log(json);//{"name":"weihexin","id":1}

var _data = JSON.parse(json);//返回 js Object
console.log(_data);//{name: "weihexin", id: 1}
