Jquery SetTimeOut

倒计时 59 秒:

var c=59
var t
function timedCount()
{
document.getElementById(‘txt‘).value=c
if(c>0){
c--;
}else{
clearTimeout(t);
}
t=setTimeout("timedCount()",1000)
}
</script>

计时器设置一个时钟：

function startTime()
{
var today=new Date()
var h=today.getHours()
var m=today.getMinutes()
var s=today.getSeconds()
m=checkTime(m)
s=checkTime(s)
document.getElementById(‘txt‘).innerHTML=h+":"+m+":"+s
t=setTimeout(‘startTime()‘,500)
}

function checkTime(i)
{
if (i<10)
  {i="0" + i}
  return i
}
