我想要一个表示当前日期和时间的数字,比如Unix时间戳。
当前回答
function getTimeStamp() {
var now = new Date();
return ((now.getMonth() + 1) + '/' +
(now.getDate()) + '/' +
now.getFullYear() + " " +
now.getHours() + ':' +
((now.getMinutes() < 10)
? ("0" + now.getMinutes())
: (now.getMinutes())) + ':' +
((now.getSeconds() < 10)
? ("0" + now.getSeconds())
: (now.getSeconds())));
}

console.log(newDate().valueOf());//返回自epoch以来的毫秒数
更简单的方法:
var timeStamp=event.timestamp || new Date().getTime();
任何不支持Date.now的浏览器,您都可以使用它获取当前日期时间:
currentTime = Date.now() || +new Date()
我还没见过
Math.floor(Date.now() / 1000); // current time in seconds
另一个我还没看到的是
var _ = require('lodash'); // from here https://lodash.com/docs#now
_.now();
/**
* Equivalent to PHP's time(), which returns
* current Unix timestamp.
*
* @param {string} unit - Unit of time to return.
* - Use 's' for seconds and 'ms' for milliseconds.
* @return {number}
*/
time(unit = 's') {
return unit == 's' ? Math.floor(Date.now() / 1000) : Date.now()
}
