例如,给定输入框中的两个日期:
<input id="first" value="1/1/2000"/>
<input id="second" value="1/1/2001"/>
<script>
alert(datediff("day", first, second)); // what goes here?
</script>
如何在 JavaScript 中获取两个日期之间的天数?

function datediff(first, second) {
// Take the difference between the dates and divide by milliseconds per day.
// Round to nearest whole number to deal with DST.
return Math.round((second-first)/(1000*60*60*24));
}
alert(datediff(parseDate(first.value), parseDate(second.value)));
