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"
