javascript实现高考倒计时效果

script

var d=new Date();

var dt=new Date();

dt.setFullYear(d.getFullYear(),5,7);

if(dtd)

{

dt.setFullYear(d.getFullYear()+1,5,7);

}

document.write("离高考还有"+(dt-d)/3600/24/1000+"天");

/script

改了，加了个判断。刚理解错了。。

Q1: 如何用js实现高考倒计时

这是2014年高考倒计时的代码，可以自己修改只需要更改BirthDay=new Date("7-6-2014"); 里面的数字就可以。测试可用。

SCRIPT language=javascript

function show_date_time(){

window.setTimeout("show_date_time()", 1000);

BirthDay=new Date("7-6-2014");

today=new Date();

timeold=(BirthDay.getTime()-today.getTime());

sectimeold=timeold/1000

secondsold=Math.floor(sectimeold);

msPerDay=24*60*60*1000

e_daysold=timeold/msPerDay

daysold=Math.floor(e_daysold);

e_hrsold=(e_daysold-daysold)*24;

hrsold=Math.floor(e_hrsold);

Q3: 求一个高考倒计时的js代码，加解释?

var scount = 0;

$(function () {

var start = setInterval(function () {

var dtstr = "";

var now = new Date();//初始化当前时间

var newdatr = new Date(now.getFullYear(), "05", "07", "00", "00", "00", "00");//初始化目标时间(这里的05实际上是六月)

var nowhms = now.getTime();//当前时间转换毫秒

var newhms = newdatr.getTime();//目标时间转换毫秒

var cha = newhms - nowhms;//时间差（毫秒数）

if (cha 0) {

var day = parseInt(cha / (1000 * 60 * 60 * 24));//计算天数

var hh = parseInt((cha % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));//计算小时

var min = parseInt(((cha % (1000 * 60 * 60 * 24)) % (1000 * 60 * 60)) / (1000 * 60));//计算分钟

var ss = parseInt((((cha % (1000 * 60 * 60 * 24)) % (1000 * 60 * 60)) % (1000 * 60)) / 1000);//计算秒

if (ss == 0) {

scount += 1;

}

//var ms = parseInt((((cha % (1000 * 60 * 60 * 24)) % (1000 * 60 * 60)) % (1000 * 60)) % 1000);

dtstr = day + "天" + hh + "小时" + min + "分钟" + ss + "秒";//+ ms + "毫秒";

}

$("#timestr").html(dtstr);

$("#flag").html("你已经续了" + scount + "分钟。");

}, 1000);

});
