一些页面自动跳转的实现

(转自http://www.blogjava.net/Jcat/archive/2006/11/22/82831.html)

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
 
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>
