我要评论js实现倒计时(一个页面多个倒计时)
$p.end_time:后台传来的时间戳 data-timestamp:自定义倒计时属性 -->
$.each($(".day-countdown"),function(){
var timer = [];
timer.push($(this).data("timestamp"));
var pid = [];
pid.push($(this).attr("id"));
var date = new date(parseint(timer)*1000);
if(timer!=0){
setinterval(function(){
showcountdown(
date.getfullyear(),
date.getmonth()+1,
date.getdate(),date.gethours(),
date.getminutes(),
date.getseconds(),
pid);
},1000);
}
});
function showcountdown(year,month,day,h,m,s,pname)
{
var now = new date();
var enddate = new date(year, month-1, day,h,m,s);
var lefttime=enddate.gettime()-now.gettime();
var leftsecond = parseint(lefttime/1000);
var day1=checktime(math.floor(leftsecond/(60*60*24)));
var hour=checktime(math.floor((leftsecond-day1*24*60*60)/3600));
var minute=checktime(math.floor((leftsecond-day1*24*60*60-hour*3600)/60));
var second=checktime(math.floor(leftsecond-day1*24*60*60-hour*3600-minute*60));
var cc = document.getelementbyid(pname);
if(day1 <= 0 && hour <= 0 && minute <=0 && second <= 0){
window.clearinterval();
}else if(day1 === "0-1" || hour === "0nan" || minute === "0nan" || second === "0nan"){
window.clearinterval();
}else if(day1 == "00" && (hour != "0" || minute != "0" || second != "0")){
cc.innerhtml = hour+":"+minute+":"+second; //有效期在24小时内开始时分秒倒计时
}else{
if(cc != null){
cc.innerhtml = parseint(day1)+"天"; //有效期在24小时外以天为单位进行倒计时
}
}
}
function checktime(i){
if (i < 10) {
i = "0" + i;
}
return i;
}
