1）html的实现
<head> <meta http-equiv="refresh" content="5;url=hello.html"> </head>
优点：简单
缺点：Struts Tiles中无法使用
<script language="Javascript" type="text/javascript"> setTimeout("javascript:location.href='hello.html'", 5000); </script>
优点：灵活，可以结合更多的其他功能
缺点：受到不同浏览器的影响
3）结合了倒数的javascript实现（IE）
<span id="totalSecond">5</span>
<script language="javascript" type="text/javascript"> var second = totalSecond.innerText; setInterval("redirect()", 1000); function redirect(){ totalSecond.innerText=--second; if(second<0) location.href='hello.html'; } </script>
优点：更人性化
缺点：Firefox不支持（firefox不支持span、div等的innerText属性）
3'）结合了倒数的javascript实现（firefox）
<script language="javascript" type="text/javascript"> var second = document.getElementById('totalSecond').textContent; setInterval("redirect()", 1000); function redirect() { document.getElementById('totalSecond').textContent = --second; if (second < 0) location.href = 'hello.html'; } </script>
4）解决Firefox不支持innerText的问题
<span id="totalSecond">5</span>
<script language="javascript" type="text/javascript"> if(navigator.appName.indexOf("Explorer") > -1){ document.getElementById('totalSecond').innerText = "my text innerText"; } else{ document.getElementById('totalSecond').textContent = "my text textContent"; } </script>
5）整合3）和3'）
<span id="totalSecond">5</span>
<script language="javascript" type="text/javascript"> var second = document.getElementById('totalSecond').textContent; if (navigator.appName.indexOf("Explorer") > -1) { second = document.getElementById('totalSecond').innerText; } else { second = document.getElementById('totalSecond').textContent; } setInterval("redirect()", 1000); function redirect() { if (second < 0) { location.href = 'hello.html'; } else { if (navigator.appName.indexOf("Explorer") > -1) { document.getElementById('totalSecond').innerText = second--; } else { document.getElementById('totalSecond').textContent = second--; } } } </script>

我实验了 “5）整合3）和3'）” 如下:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"><HTML> <HEAD> <TITLE> New Document </TITLE> <META NAME="Generator" CONTENT="EditPlus"> <META NAME="Author" CONTENT=""> <META NAME="KeyWords" CONTENT=""> <META NAME="Description" CONTENT=""> </HEAD> <BODY> <span id="totalSecond">5</span> </BODY><script language="javascript" type="text/javascript"> var second = document.getElementById('totalSecond').textContent; if (navigator.appName.indexOf("Explorer") > -1) { second = document.getElementById('totalSecond').innerText; } else { second = document.getElementById('totalSecond').textContent; } setInterval("redirect()", 1000); function redirect() { if (second < 0) { location.href = 'http://www.baidu.com/'; } else { if (navigator.appName.indexOf("Explorer") > -1) { document.getElementById('totalSecond').innerText = second--; } else { document.getElementById('totalSecond').textContent = second--; } } } </script></HTML>
