功能实现 : 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

  1. 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

  1. 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>

<!-- 或者 -->

<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>

优点:更人性化 缺点:firefox不支持(firefox不支持span、div等的innerText属性)

  1. 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>
  1. 整合
<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>
