问题描述

我有一个jQuery时钟，给出了从00:00到23:00的时间.

I have a jQuery clock that gives the time from 00:00 to 23:00.

现在，我想计算两次之间的时间差.假设进"时间为11:00，出"时间为16:00.

Now I want to calculate the time difference between two times. Suppose the "in" time is 11:00, and the "out" time is 16:00.

如何计算javascript中的时差?

How do I calculate the time difference in javascript?

推荐答案

您可以像这样使用Date和setHours:

You can use Date and setHours like that:

var first = new Date();
first.setHours(0, 11, 0, 0);

var second = new Date();
second.setHours(0, 16, 0, 0);

alert("Diff in seconds: " + (second - first));
