下面列了五个例子来详细说明，这几个例子的主要功能是：在5秒后，自动跳转到同目录下的hello.html（根据自己需要自行修改）文件。
1) html的实现

|
<head>
<meta http-equiv="refresh" content="10">
<meta http-equiv="refresh" content="5;url=hello.html">
</head>
|
优点：简单
缺点：Struts Tiles中无法使用
2) javascript的实现

<script language="javascript" type="text/javascript">
window.location.href='hello.html';
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">

document.getElementById('totalSecond').innerText = "my text innerText";
} else{
document.getElementById('totalSecond').textContent = "my text textContent";
}
</script>

} 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>
