向Javascript日期对象timeObject添加10秒

Question

如何为javascript日期对象timeObject添加10秒.我认为这样的事情......

var timeObject = new Date()     
var seconds = timeObject.getSeconds() + 10;
timeObject = timeObject + seconds;

Answer 1

还有一种setSeconds方法:

var t = new Date();
t.setSeconds(t.getSeconds() + 10);

有关其他 Date功能的列表,您应该查看MDN

setSeconds 将正确处理环绕案件:

var d;
d = new Date('2014-01-01 10:11:55');
alert(d.getMinutes() + ':' + d.getSeconds()); //11:55
d.setSeconds(d.getSeconds() + 10);
alert(d.getMinutes() + ':0' + d.getSeconds()); //12:05

Answer 2

// var timeObject = new Date();

new Date(timeObject.getTime() + 10000);

Answer 3

var timeObject = new Date(); 
timeObject = new Date(timeObject .getTime() + 1000*10);
console.log(timeObject);

Answer 4

只是为了我们中间的表现狂.

的getTime

var d = new Date('2014-01-01 10:11:55');
d = new Date(d.getTime() + 10000);

5,196,949 Ops/sec,最快

调用setSeconds

var d = new Date('2014-01-01 10:11:55');
d.setSeconds(d.getSeconds() + 10);

2,936,604 Ops/sec,慢43%

moment.js

var d = new moment('2014-01-01 10:11:55');
d = d.add(10, 'seconds');

22,549 Ops/sec,慢100%

所以也许它是最不可读的(不是那么糟糕)但是最快的方式:)

Answer 5

试试这个

a = new Date();
a.setSeconds(a.getSeconds() + 10);

Answer 6

我有几个新的变体

1. var t = new Date(Date.now() + 10000);
2. var t = new Date(+new Date() + 10000);
