效果：
插件代码：
$(function(){
function jisuanTime_daojishi(){
$(".daojishi").each(function(){
var endtime = $(this).attr("daojishi_time");
endtime=new Date(endtime);
var nowtime = new Date();
var leftsecond = parseInt((endtime.getTime()-nowtime.getTime())/1000);
if(leftsecond<=0){
$(this).html("抢购已结束");
}else{
var date = parseInt(leftsecond/3600/24);
var hour = parseInt((leftsecond/3600)%24);
var miniute = parseInt((leftsecond/60)%60);
var second = parseInt(leftsecond%60);
$(this).html("剩余："+date + "天" + hour + "小时" + miniute +"分" + second +"秒");
}
});
}
var sh = setInterval(jisuanTime_daojishi,1000);
})
