问题描述

求js大神~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

if(orderTime+7天>当前时间){
alert(""订单时间已超过退差价范围!"");
window.close();
}

    如何让我获取到的orderTime能加上7天，和当前的时间比较呢，格式都要 yy-MM-dd

解决方案

 <script type=""text/javascript"">function AddDays(datedays){   var nd = new Date(date);   return calDays(nddays);}function calDays(nddays){   nd = nd.valueOf();   nd = nd + days * 24 * 60 * 60 * 1000;   nd = new Date(nd);   //alert(nd.getFullYear() + ""年"" + (nd.getMonth() + 1) + ""月"" + nd.getDate() + ""日"");var y = nd.getFullYear();var m = nd.getMonth()+1;var d = nd.getDate();if(m <= 9) m = ""0""+m;if(d <= 9) d = ""0""+d; var cdate = y+""-""+m+""-""+d;return cdate;}var str='2015-06-22';var strAdded = AddDays(str7);var curDate  = calDays(new Date()0);if(strAdded>curDate){  alert(""大于"");}else{  alert(""不大于"");}</script>

解决方案三：

    function OverDate(s days) {        s = '20' + s;        var d = new Date(s.replace(/-/g '/')) now = new Date();        now = new Date(now.getFullYear() + '/' + (now.getMonth() + 1) + '/' + now.getDate());//去掉时间部分        d.setDate(d.getDate() + days);        return d.getTime() > now.getTime();    }    if (OverDate('15-07-16' 7)) alert(""订单时间已超过退差价范围!"");    if (OverDate('15-07-13' 7)) alert(""订单时间已超过退差价范围!"");
