Javascript倒计时页面跳转实例小结

例1：
代码如下:
<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) //当倒计时结束
        {
            window.focus();
            setInterval("blinkNewMsg()", 1000);
            window.location.reload();
        }
        if(nS < 10) nS = "0" + nS;

        if(nMS >= 0){
            document.getElementById("remainTime").innerHTML= nM + "分" + nS + "秒";
            setTimeout("getRemainTime()",1000);
        }       
    }   
    function blinkNewMsg()
    {
        document.title = g_blinkswitch % 2==0 ? "【　　　】 - " + g_blinktitle : "【新消息】 - " +
        g_blinktitle;
        g_blinkswitch++;
    }   
 window.onload=getRemainTime;
</script>
<strong id="remainTime">10分00秒</strong>

倒计时跳转页面

代码如下:
<title>JS倒计时网页自动跳转代码</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>秒钟后自动跳转，如果不跳转，请点击下面的链接<a href="//www.Vevb.com">我的百度</a>
<script type="text/javascript">
delayURL("//www.Vevb.com");
</script>
