功能：5秒后，自动跳转到同目录下的02view.html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
<
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
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
<
script
language
="javascript"
type
="text/javascript"
>
setTimeout( " javascript:location.href='02view.html' " , 5000 );
</ script >
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）
优点：更人性化
缺点：firefox不支持（firefox不支持span、div等的innerText属性）
<
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 >
< 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 >
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 = " mytextinnerText " ;
} else {
document.getElementById('totalSecond').textContent = " mytexttextContent " ;
}
</ script >
< script language ="javascript" type ="text/javascript" >
if (navigator.appName.indexOf( " Explorer " ) > - 1 ){
document.getElementById('totalSecond').innerText = " mytextinnerText " ;
} else {
document.getElementById('totalSecond').textContent = " mytexttextContent " ;
}
</ 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 >
< 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 >
