我尝试这段代码

start_time = '08:15 AM'
end_time = '03:45 PM'
diff = end_time - start_time;

只有我想减去jquery中的时间。我已经尝试在php中进行如下操作，并且运行正常。
但不在jQuery中

$st = strtotime("07:30 AM");
$edt = strtotime("06:15 AM");
echo round(abs($st - $edt) / 60,2). " minute";
echo "<br>";

echo $timediff=($edt-$st)/60;

最佳答案

使用Date()对象。您不能像问题中那样减去字符串。

a = new Date(2012, 1, 2, 21, 1, 3, 5)
b = new Date(2012, 2, 3, 22, 2, 3, 5)
c = a - b // diff in milliseconds
