HTML頁面定時跳轉方法

標籤：des   style   blog   http   io   ar   color   使用   sp   

1）html的實現

<head>
<meta http-equiv="refresh" content="5;url=hello.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=‘hello.html‘", 5000);
</script>

優點：靈活，可以結合更多的其他功能

缺點：受到不同瀏覽器的影響

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=‘hello.html‘;
}
</script>

優點：更人性化

缺點：firefox不支援（firefox不支援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 = ‘hello.html‘;
}
</script>

4）解決Firefox不支援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 = ‘hello.html‘;
} else
{
if (navigator.appName.indexOf("Explorer") > -1)
{
document.getElementById(‘totalSecond‘).innerText = second--;
} else
{
document.getElementById(‘totalSecond‘).textContent = second--;
}
}
}
</script>

我實驗了  “5）整合3）和3‘）” 如下:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"><HTML> <HEAD>  <TITLE> New Document </TITLE>  <META NAME="Generator" CONTENT="EditPlus">  <META NAME="Author" CONTENT="">  <META NAME="Keywords" CONTENT="">  <META NAME="Description" CONTENT=""> </HEAD> <BODY>  <span id="totalSecond">5</span> </BODY><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.baidu.com/‘; } else { if (navigator.appName.indexOf("Explorer") > -1) { document.getElementById(‘totalSecond‘).innerText = second--; } else { document.getElementById(‘totalSecond‘).textContent = second--; } } } </script></HTML>
