如何获得两个日期之间的差额？

我有：

date1 = 2014/2/20
date2 = 2014/2/16

我想将差值作为4。

最佳答案

Fiddle Demo

var oneDay = 24 * 60 * 60 * 1000;
function getDateDiffinDays(d1, d2) {
    var firstDate = new Date(d1);
    var secondDate = new Date(d2);
    return Math.round(Math.abs((firstDate.getTime() - secondDate.getTime()) / (oneDay)));
}

alert(getDateDiffinDays('2014/2/20', '2014/2/16'));
