Date.prototype.toISOString()
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
toISOString() 方法返回一个 ISO（ISO 8601 Extended Format）格式的字符串： YYYY-MM-DDTHH:mm:ss.sssZ。时区总是 UTC（协调世界时），加一个后缀“Z”标识。
尝试一下
const event = new Date("05 October 2011 14:48 UTC");
console.log(event.toString());
// Expected output: "Wed Oct 05 2011 16:48:00 GMT+0200 (CEST)"
// Note: your timezone may vary
console.log(event.toISOString());
// Expected output: "2011-10-05T14:48:00.000Z"
语法
dateObj.toISOString()
示例
使用 toISOString()
js
const d = new Date(0);
console.log(d.toISOString()); // "1970-01-01T00:00:00.000Z"
