倒计时69天!大家倒计时多少天了?
我是倒计时90天了,很享受宝宝每天胎动的时间
什么是倒计时载入页面的JS代码?
diffSecs = timeDiff/1000; //因为时间以毫秒为单位 return(this。diffSecs); //返回间隔秒数} function getSecs() { var mySecs = initStopwatch(); var mySecs1 = +mySecs; //以倒计时方式显示时间 mySecs1= 10 - eval(mySecs1。
js倒计时代码
离半夜12点还有

小时




function countdown() {
var today = new Date();
var h = today.getHours();
var m = today.getMinutes();
h = 23 - h;
m = 59 - m;
m = checkTime(m)
document.getElementById("hour").innerHTML=h;
document.getElementById("min").innerHTML=m;
}
function checkTime(i) {
if (i<10) i = "0" + i;
return i;
}
setInterval("countdown()", 50);


小时




function showtime(){
var tartime = new Date();
var nowtime = new Date();
tartime.setHours(24,0,0,0);
var tartime = tartime.getTime();
var nowtime = nowtime.getTime();
var time = tartime - nowtime;
var seconds = Math.floor(time/1000);
var mins = Math.floor(seconds/60);
var hours = Math.floor(mins/60);
var nowmins = mins%60;
var nowsec = seconds%60;
document.getElementById('hour').innerHTML = hours;
document.getElementById('min').innerHTML = nowmins;
document.getElementById('sec').innerHTML = nowsec;
showtime();
setInterval(showtime,1000);
还加了秒数。倒计时。放在body中
JS如何倒计时?
var t=60;
var a=setInterval(daojishi,1000);//1000毫秒
function daojishi(){
t--;
//刷新时间显示
if(t==0){
clearInterval(a);
//倒计时结束
}
}window.setTimeout("setPopTitle();",20*1000);
function setPopTitle()
{
alert("20秒到了");
}
如果是20秒后想调后台,就用ajax直接调
