两次之间的时间差在js中显示错误的值

Question

我想使用javascript检查两次之间的时差并以分钟为单位得到时差，并且我的时间格式是上午12点（上午/下午）

例如：

比较（10:35 am）-（01:15 pm）=？分钟

但是问题是我为此得到了错误的值，因此如何使用JavaScript计算两次之间的分钟数

<script>

var timeStart = new Date("01/23/2020 " + "05:00 AM");
var timeEnd = new Date("01/23/2020 " + "06:30 PM");

var diff = (timeEnd - timeStart) / 60000; 

var minutes = diff % 60;
var hours = (diff - minutes) / 60;
alert(minutes);
alert(hours);

</script>

Answer 1

这可能是简短而甜蜜的解决方案

var diff = Math.abs(new Date('01/23/2020 06:30 PM') - new Date('01/23/2020 05:00 AM'));
var minutes = Math.floor((diff/1000)/60);
alert(minutes);

Answer 2

总分钟数将计算为

var timeStart = new Date("01/23/2020 " + "05:00 AM");
var timeEnd = new Date("01/23/2020 " + "06:30 PM");

var diff = (timeEnd - timeStart) / 60000; 

var minutes = diff % 60;
var hours = (diff - minutes) / 60;
var totalMinutes = (hours*60)+minutes;
alert(totalMinutes);
