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>

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>

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>

4) 解决Firefox不支持innerText的问题

<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>

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>
