jQuery 倒计时

function getSec(){

//获取名称为remindataSec的ul

obj = document.getElementsByName("remindataSec");

for(i=0;i<obj.length;i++){

//循环得到每个毫秒数

var intDiff = $("#remindataTime"+i+"").text();

var id = "reminTime"+i;

//得到毫秒数和li标签的id

timer(intDiff,id);

}

}

//倒计时类型 为 0：00:00  小时：分钟：秒数

function timer(intDiff,id){

window.setInterval(function(){

var hour=0,

minute=0,

second=0;//时间默认值

if(intDiff > 0){

hour = Math.floor(intDiff/3600);

minute = Math.floor((intDiff-(hour*3600))/60);

second = Math.floor(intDiff-(hour*3600)-(minute*60));

}

if (minute <= 9) minute = ‘0‘ + minute;

if (second <= 9) second = ‘0‘ + second;

var daojishi= hour+":"+minute+":"+second;

if(intDiff<=600){

$(‘#‘+id+‘‘).css("color","red");

}

if(intDiff<=0){

searchMemo();

}

$(‘#‘+id+‘‘).text(daojishi+"  以后");

intDiff--;

}, 1000);
