Javascript
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>
