JSP三秒自动跳转到另一页

<meta http-equiv=refresh content='5;url=http://www.sohu.com'>

<p style="text-indent: 2em; margin-top: 30px;">

系统将在 <span id="time">5</span> 秒钟后自动跳转至新网址，如果未能跳转，<a href="http://www.baidu.com" title="点击访问">请点击</a>。</p>

<script type="text/javascript">  

    delayURL();   

    function delayURL() {

        var delay = document.getElementById("time").innerHTML;

       var t = setTimeout("delayURL()", 1000);

        if (delay > 0) {

            delay--;

            document.getElementById("time").innerHTML = delay;

        } else {

     clearTimeout(t);

            window.location.href = "http://wwwbaodu.com";

        }       

    }
