In JS to achieve page timing jump we want to use the SetInterval or settimeout function, of course, you can also use the Metea implementation of the page, I introduce the following two examples.

Example 1

Countdown Refresh Page

The code is as follows

<script type= "Text/javascript" language= "JavaScript" >

var starttime = new Date ();
var endtime=starttime.gettime () +10*60*1000;
var g_blinkswitch = 0;
var g_blinktitle = Document.title;
function Getremaintime () {

var nowtime = new Date ();
var NMS =endtime-nowtime.gettime ();
var Nm=math.floor (nms/(1000*60))% 60;
var ns=math.floor (nms/1000)% 60;
if (nm==0&&ns==0&&nms<1000)//When the countdown is over
{
Window.focus ();
SetInterval ("blinknewmsg ()", 1000);
Window.location.reload ();
}
if (ns < NS) = "0" + ns;

if (NMS >= 0) {
document.getElementById ("Remaintime"). Innerhtml= NM + "min" + NS + "seconds";

SetTimeout ("Getremaintime ()", 1000);
}

}

function blinknewmsg ()
{
Document.title = g_blinkswitch% 2==0? ""-"+ G_blinktitle:" "New Message"-"+
G_blinktitle;
g_blinkswitch++;
}


Window.onload=getremaintime;

</script>

<strong id= "Remaintime" >10 minute 00 sec </strong>

Example 2

Countdown Jump Page

The code is as follows

<TITLE>JS Countdown page Auto Jump code </title>
<script language= "JavaScript" type= "Text/javascript" >
function Delayurl (URL) {
var delay = document.getElementById ("Time"). InnerHTML;
if (Delay > 0) {
delay--;
document.getElementById ("Time"). InnerHTML = delay;
} else {
Window.top.location.href = URL;
}
SetTimeout ("delayurl (' + URL + ')", 1000);
}
</script>
<span id= "Time" style= "background: #00BFFF" >3</span> seconds after automatic jump, if not jump, please click the link below <a href= "http:// Www.45it.com "> My Baidu </a>
<script type= "Text/javascript" >
Delayurl ("http://www.45it.com");
</script>

Anti-Refresh Countdown code

The code is as follows

<! DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 transitional//en" "Http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd "> 
<meta http-equiv= "Content-type" content= "text/html; charset=gb2312 "/> 
<title> www.45it.com</title> 
<body >&NBSP
<script language= "JavaScript" > 
<!-- 
var maxtime; 
if ( window.name== ') { 
MaxTime = 1*60; 
}else{ 
MaxTime = window.name; 

function countdown () { 
if (maxtime>=0) { 
minutes = Math.floor (MAXTIME/60);  
seconds = Math.floor (maxtime%60);  
msg = distance to the end of the exam there is also "+minutes+" +seconds+ "seconds";  
document.all["Timer". InnerHTML = msg; 
if (maxtime = = 5*60) alert (' Note, there are 5 minutes! '); &NBSP
--maxtime; 
Window.name = maxtime; 

else{ 
ClEarinterval (timer);  
Alert ("Test time to, end!"); &NBSP


Timer = SetInterval ("Countdown ()", 1000);  
//-->
</SCRIPT> &NBSP
<div id= "Timer" style= "color:red" ></DIV>&NBSP;
</body>
