用jQuery进行时间减法 [英] Doing time subtraction with jQuery

问题描述

我在页面上有两个时间值:

I have two time values on a page:

8:00
22:30

我需要从22:30减去8并得到14:30.

I need to subtract 8 from 22:30 and get 14:30.

在jQuery中有直接的方法吗?如果有必要，插件对我来说很好.

Is there a straight forward way to do that in jQuery? Plug-ins are fine by me if they're necessary.

更新: 第二个数字是总数，所以也可能是

Update: The second number is a grand total so it could also be something like

48:45

我从中减去的任何东西都应该从中减去总和，而不进行任何与日期相关的计算.

Anything I subtract from it should just subtract the value from it as a total, not do any date related calculations.

推荐答案

您可以在javascript中完成它.

You can do it in javascript.

假设您有start = '8:00'和end = '22:30'.代码如下:

Suppose you have start = '8:00' and end = '22:30'. The code is as follows:

<script type="text/javascript">
    var start = '8:00';
    var end = '23:30';

    s = start.split(':');
    e = end.split(':');

    min = e[1]-s[1];
    hour_carry = 0;
    if(min < 0){
        min += 60;
        hour_carry += 1;
    }
    hour = e[0]-s[0]-hour_carry;
    diff = hour + ":" + min;

    alert(diff);
</script>

最后，diff是您的时差.
