Date.prototype.toTimeString()

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.

toTimeString() 方法以人类易读形式返回一个日期对象时间部分的字符串，该字符串以美式英语格式化。

尝试一下

const event = new Date("August 19, 1975 23:15:30");

console.log(event.toTimeString());
// Expected output: "23:15:30 GMT+0200 (CEST)"
// Note: your timezone may vary

语法

dateObj.toTimeString()

描述

Date 对象的实例引用一个具体的时间点。调用 toString 方法以美式英语和人类易读的形式，返回日期对象的格式化字符串。在 SpiderMonkey 里，该字符串由日期部分（年月日）和其后的时间部分（时分秒和时区）组成。有时会需要获取时间部分的字符串，这可以由 toTimeString 方法完成。

The toTimeString method is especially useful because compliant engines implementing ECMA-262 may differ in the string obtained from toString for Date objects, as the format is implementation-dependent; simple string slicing approaches may not produce consistent results across multiple engines.

示例

示例：toTimeString 方法的简单使用

js
var d = new Date(1993, 6, 28, 14, 39, 7);

println(d.toString()); // prints Wed Jul 28 1993 14:39:07 GMT-0600 (PDT)
println(d.toTimeString()); // prints 14:39:07 GMT-0600 (PDT)
