HTML页面自动跳转的五种实现方法

阅读更多

下面列了五个例子来详细说明,这几个例子的主要功能是:在5秒后,自动跳转到同目录下的hello.html(根据自己需要自行修改)文件。

1)html的实现

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