我正在计算“开始”日期和“结束”日期之间的天数。例如，如果开始日期为 mm/dd/yyyy，结束日期为 mm/dd/yyyy。如何使用 JavaScript 获取结果？

起始日期如下:11/25/2014到目前为止是这样的:11/27/2014

来自John Resig的实现:

// Get date difference.
// @see http://ejohn.org/projects/javascript-pretty-date/
function prettyDate(date, now){
    var diff = (((now || (new Date())).getTime() - date.getTime()) / 1000),
        day_diff = Math.floor(diff / 86400);

    if (isNaN(day_diff) || day_diff < 0 || day_diff >= 31)
        return this.format(date, 'yyyy-mm-dd');

    return day_diff == 0 && (
            diff < 60 && "Just now" ||
            diff < 120 && "1 minute ago" ||
            diff < 3600 && Math.floor( diff / 60 ) + " minutes ago" ||
            diff < 7200 && "1 hour ago" ||
            diff < 86400 && Math.floor( diff / 3600 ) + " hours ago") ||
        day_diff == 1 && "yesterday" ||
        day_diff < 7 && day_diff + " days ago" ||
        day_diff < 31 && Math.ceil( day_diff / 7 ) + " weeks ago";
},
