答案 1 :(得分：0)
对于添加的日期字段，您可以使用regex函数在字符串内部查找数字并解构数组以获取相应的字段
let [year, month, day] = object["AddedDate"].match(/\d+/g);
console.log(day, month, year) //returns 15 02 2014
然后您可以根据需要设置日期格式
console.log(`${day}-${month}-${year.substr(2)}`) //returns 15-02-14
答案 2 :(得分：0)
看一下文档 https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/UTC
var timestamp = Date.parse('2014-01-23T13:10:29Z')
然后，您可以使用返回的时间戳做任何您想做的事情
date = new Date(timestamp);
console(date.getFullYear());
答案 3 :(得分：0)
我们想在reviver函数中为日期补水，传递给JSON.parse（）。它将处理您的刚刚约会和您的iso日期。它在这里工作...
function nReviver(key, value) {
var a;
if (typeof value === "string") {
// match any string that looks like a date, with or without a time. YYYY-MM-DD(Thh:mm:ss(.0000)?Z?)?
a = /^((\d{4})-(\d{2})-(\d{2}))(T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z?)?$/.exec(value);
if (a) {
// No default values. All zero dates replaced with null.
if (a[1] === '0001-01-01') { return null; }
// sby JSON.net loves datetimes with timezone unspecified. We prefer them as UTC.
if (value.slice(-1) !== 'Z')
value += 'Z';
return new Date(Date.UTC(+a[2], +a[3] - 1, +a[4], +a[5] || 0, +a[6] || 0, +a[7] || 0));
}
}
return value;
