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 2015年7月.
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"
