一些页面自动跳转的实现

功能:5秒后,自动跳转到http://www.adocode.com/index.html

 

1)html的实现

<head>
<meta http-equiv="refresh" content="5;url=http://www.adocode.com/index.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='http://www.adocode.com/index.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 
= 'http://www.adocode.com/index.html';
       } 
else
       {
           
if (navigator.appName.indexOf("Explorer"> -1)
           {
               document.getElementById('totalSecond').innerText 
= second--;
           } 
else
           {
               document.getElementById('totalSecond').textContent 
= second--;
           }
       }
   }
</script>
