JS获取当前时间戳的方法-JavaScript 获取当前时间戳
JavaScript 获取当前时间戳:
第一种方法:
var timestamp =Date.parse(new Date());
结果:1280977330000
第二种方法:
var timestamp =(new Date()).valueOf();
结果:1280977330748
第三种方法:
var timestamp=new Date().getTime();
结果:1280977330748
第一种:获取的时间戳是把毫秒改成000显示,
第二种和第三种是获取了当前毫秒的时间戳。
我和同事在用js实现一个显示出分析数据所剩大概时间的过程中,时间总是变给0,结果很怪异,最后发现获取时间的时候用的是Date.parse(newDate())获取的时间戳把毫秒改成了000显示,所以时间差计算的不准确。
可以用第二种或第三种方法计算时间差。
js中单独调用new Date(),例如document.write(new Date());
显示的结果是:Mar 31 10:10:43 UTC+0800 2012 这种格式的时间
但是用new Date() 参与计算会自动转换为从1970.1.1开始的毫秒数
