javascript实现页面自动跳转

1、脚本如下

      

<span id="time" style="background:red">10</span>秒钟后自动跳转，如果不跳转，请点击下面链接 

<script language="JavaScript1.2" 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>

 2、调用

         

<script type="text/javascript">
	 delayURL("您需要跳转到的目标页面");
  </script>
