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02view.html(根据自己需要自行修改)文件。
1)html的实现
<head>
<meta
http-equiv="refresh" content="5;url=02view.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='02view.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='02view.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 = '02view.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
= '02view.html';
}
else
{
if
(navigator.appName.indexOf("Explorer") > -1)
{
document.getElementById('totalSecond').innerText
= second--;
}
else
{
document.getElementById('totalSecond').textContent
= second--;
}
}
}
</script>
