功能：5秒後，自動跳轉到同目錄下的02view.html文件
1）html的實現
<head>
<meta http-equiv="refresh" content="5;url=02view.html">
</head>
優點：簡單
缺點：Struts Tiles中無法使用
2）javascript的實現
<script language="javascript" type="text/javascript">
setTimeout("javascript:location.href='02view.html'", 5000);
</script>
優點：靈活，可以結合更多的其他功能
缺點：受到不同浏覽器的影響
3）結合了倒數的javascript實現（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>
優點：更人性化
缺點：firefox不支持（firefox不支持span、div等的innerText屬性）
3'）結合了倒數的javascript實現（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）解決Firefox不支持innerText的問題
<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>
