js 时间差(过去了多少时间、还剩多少时间）

前言：date.format() 函数，请参照之前的文章

最好用的JS时间date操作类（时间格式化、加减日、月、年、操作）

<pre name="code" class="javascript">function getDate(timestamp) {        var date = new Date(timestamp);        return date.format("yyyy-MM-dd hh:mm:ss");    }

1.过去了多少时间（xx天xx小时xx分钟xx秒之前）

    function timeago(timestamp) {        var d_minutes, d_hours, d_days, d_seconds;        var timeNow = parseInt(new Date().getTime() / 1000);        d_seconds = timeNow - timestamp / 1000;        d_days = parseInt(d_seconds / 86400);        d_hours = parseInt(d_seconds / 3600);        d_minutes = parseInt(d_seconds / 60);        if (d_days > 0 && d_days < 4) {            return d_days + "天前";        } else if (d_days <= 0 && d_hours > 0) {            return d_hours + "小时前";        } else if (d_hours <= 0 && d_minutes > 0) {            return d_minutes + "分钟前";        } else if (d_minutes <= 0 && d_seconds > 0) {            return d_seconds + "秒前";        } else {            return getDate(timestamp);        }    }

2.还剩多少时间结束（xx天xx小时xx分钟xx秒）

function timediff(timestamp) {        var d_minutes, d_hours, d_days, d_seconds, ret = "";        var timeNow = parseInt(new Date().getTime() / 1000);        d_seconds = timestamp / 1000 - timeNow;        if (d_seconds < 0) {            return -1;        }        d_days = parseInt(d_seconds / 86400);        d_hours = parseInt(d_seconds / 3600) - d_days * 24;        d_minutes = parseInt(d_seconds / 60) - d_days * 24 * 60 - d_hours * 60;        if (d_days > 0)            ret += d_days + "天";        if (d_hours > 0)            ret += d_hours + "时";        if (d_minutes > 0)            ret += d_minutes + "分";        return ret + (d_seconds - d_days * 24 * 60 * 60 - d_hours * 60 * 60 - d_minutes * 60) + "秒";    }
