{
var time1 = arguments[0], time2 = arguments[1];
time1 = Date.parse(time1)/1000;
time2 = Date.parse(time2)/1000;
var time_ = time1 - time2;
return (time_/(3600*24));
}
document.write(getTime2Time('2016-08-02', '2016-07-02'));
start = "2016/09/09";
time = (new Date(start)).getTime();
time \u5c31\u662f\u65f6\u95f4\u6233\u7684\u6beb\u79d2\u6570
得出两个时间差的毫秒数
获得时间的毫秒级时间戳的方式是使用getTime方法
得到毫秒级时间戳后可以根据自己的需求转为时分秒等格式
