dateObj.toJSON()
Date 实例引用一个具体的时间点。 调用 toJSON() 返回一个 JSON 格式字符串(使用 toISOString())，表示该日期对象的值。默认情况下，这个方法常用于 JSON序列化Date对象。
toJSON() 样例var date = new Date();
console.log(date); //Thu Nov 09 2017 18:54:04 GMT+0800 (中国标准时间)
var jsonDate = (date).toJSON();
console.log(jsonDate); //"2017-11-09T10:51:11.395Z"
var backToDate = new Date(jsonDate);
console.log(backToDate); //Thu Nov 09 2017 18:54:04 GMT+0800 (中国标准时间)
