HTML页面定时跳转方法

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

2)javascript的实现

<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>

var second = totalSecond.innerText;

setInterval("redirect()", 1000);

function redirect(){

totalSecond.innerText=--second;

if(second<0) location.href='hello.html';

}

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)

var second = document.getElementById('totalSecond').textContent;

function redirect()

{

document.getElementById('totalSecond').textContent = --second;

if (second < 0) location.href = 'hello.html';

4)解决Firefox不支持innerText的问题

if(navigator.appName.indexOf("Explorer") > -1){

document.getElementById('totalSecond').innerText = "my text innerText";

} else{

document.getElementById('totalSecond').textContent = "my text textContent";

5)整合3)和3')

if (navigator.appName.indexOf("Explorer") > -1)

second = document.getElementById('totalSecond').innerText;

} else

second = document.getElementById('totalSecond').textContent;

if (second < 0)

location.href = 'hello.html';

document.getElementById('totalSecond').innerText = second--;

document.getElementById('totalSecond').textContent = second--;

我实验了  “5)整合3)和3')” 如下:

开始做,坚持做,重复做
