Answer 1

使用moment.js这很容易。类似的东西：

var a = moment('1/1/2012', 'DD/MM/YYYY');
var b = moment('1/1/2013', 'DD/MM/YYYY');
var days = b.diff(a, 'days');

Answer 2

此代码有助于解决问题的天数

var date1 = $( "#datepicker1" ).val();
var date2 = $(this).val();

date1 = new Date(date1);
date2 = new Date(date2);

var timeDiff = Math.abs(date2.getTime() - date1.getTime());
var diffDays = Math.ceil(timeDiff / (1000 * 3600 * 24));

alert(diffDays);
