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>
<!-- 以下方式只是刷新不跳转到其他页面 -->
<meta http-equiv="refresh" content="10">
<!-- 以下方式定时转到其他页面 -->
<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"> 
// 以下方式直接跳转
window.location.href=\'hello.html\';
// 以下方式定时跳转
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>
