jquery如何实现倒计时效果
首先获取当前时间与目标时间的时间差,然后通过定时器更新这个时间差,就实现了倒计时效果。实现上述过程需要以下两个函数:

getTime() // 返回距1970年1月1日之间的毫秒数,这样将时间差(毫秒数)÷3600÷24即为天数,时分秒类似
setTimeout(code,millisec); // 在指定的毫秒数后调用函数
实例演示如下
创建Html元素
div class="box"
span距离2015年国庆节还剩:/spanbr
div class="content"
input type="text" id="time_d"天input type="text" id="time_h"时input type="text" id="time_m"分input type="text" id="time_s"秒
/div
/div
设置css样式
div.box{width:300px;padding:20px;margin:20px;border:4px dashed #ccc;}
div.boxspan{color:#999;font-style:italic;}
div.content{width:250px;margin:10px 0;padding:20px;border:2px solid #ff6666;}
input[type='text']{width:45px;height:35px;padding:5px 10px;margin:5px 0;border:1px solid #ff9966;}
编写jquery代码
$(function(){
show_time();
});
function show_time(){
var time_start = new Date().getTime(); //设定当前时间
var time_end = new Date("2015/10/01 00:00:00").getTime(); //设定目标时间
// 计算时间差
var time_distance = time_end - time_start;
// 天
var int_day = Math.floor(time_distance/86400000)
time_distance -= int_day * 86400000;
// 时
var int_hour = Math.floor(time_distance/3600000)
time_distance -= int_hour * 3600000;
// 分
var int_minute = Math.floor(time_distance/60000)
time_distance -= int_minute * 60000;
// 秒
var int_second = Math.floor(time_distance/1000)
// 时分秒为单数时、前面加零
if(int_day 10){
int_day = "0" + int_day;
}
if(int_hour 10){
int_hour = "0" + int_hour;
}
if(int_minute 10){
int_minute = "0" + int_minute;
}
if(int_second 10){
int_second = "0" + int_second;
}
// 显示时间
$("#time_d").val(int_day);
$("#time_h").val(int_hour);
$("#time_m").val(int_minute);
$("#time_s").val(int_second);
// 设置定时器
setTimeout("show_time()",1000);
}

求教jquery倒计时,可刷新的
从服务器请求时间。
存cookie
用html5中的存储方法 localStorage
然后我发给你个 倒计时代码,但是没有设置 存储!

jquery倒计时 设定的时间到了,不执行了。怎么写?
var range = NY-Math.round((new Date()).getTime()/1000)
.....
if(range0){
return nol(days)+' '+nol(hours)+' '+nol(min)+' '+nol(sec);
}else{
$('#new_year').html("已经结束");
}
加个判断试试,当range小于0时就是结束吧,要该时间就是改这里吧var NY = Math.round((new Date('3/08/2015 21:00:00')).getTime()/1000);
订单用jquery实现倒计时怎么写
具体代码如下所示:
!DOCTYPE html
html lang="en"
head
meta charset="UTF-8"
titleTitle/title
/head
body
span class="timespan"/span
/body
script src="libs/jquery-1.11.3.js"/script
script
var starttime = new Date("2017/11/20");
setInterval(function () {
var nowtime = new Date();
var time = starttime - nowtime;
var day = parseInt(time / 1000 / 60 / 60 / 24);
var hour = parseInt(time / 1000 / 60 / 60 % 24);
var minute = parseInt(time / 1000 / 60 % 60);
var seconds = parseInt(time / 1000 % 60);
$('.timespan').html(day + "天" + hour + "小时" + minute + "分钟" + seconds + "秒");
}, 1000);

JQuery实现的按钮倒计时效果
本文实例讲述了JQuery实现的按钮倒计时效果。分享给大家供大家参考,具体如下:
一个实现了在按钮上显示倒计时,倒计时完毕自动将按钮设置为不可用的效果,具体代码如下:
html
head
titletest
count
down
button/title
script
src="jquery1.8.3.min.js"
type="text/javascript"/script
script
type="text/javascript"
$(function
()
{
$('#btn').click(function
()
{
var
count
=
10;
var
countdown
=
setInterval(CountDown,
1000);
function
CountDown()
{
$("#btn").attr("disabled",
true);
$("#btn").val("Please
wait
"
+
count
+
"
seconds!");
if
(count
==
0)
{
$("#btn").val("Submit").removeAttr("disabled");
clearInterval(countdown);
}
count--;
}
})
});
/script
/head
body
input
type="button"
id="btn"
value="Submit"
/
/body
/html
运行效果截图如下:
希望本文所述对大家jQuery程序设计有所帮助。
jquery写 60s倒计时

//换成你的jquery库
script type="text/javascript" src="jquery.js"/script
script type="text/javascript"
var setTime;
$(document).ready(function(){
var time=parseInt($("#time").text());
setTime=setInterval(function(){
if(time=0){
clearInterval(setTime);
return;
}
time--;
$("#time").text(time);
},1000);
});
