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>
<!-- 以下方式只是刷新不跳转到其他页面 -->
<meta http-equiv="refresh" content="10">
<!-- 以下方式定时转到其他页面 -->
<meta http-equiv="refresh" content="5;url=hello.html">
</head>
2) javascript的实现
<script language="javascript" type="text/javascript"> // 以下方式直接跳转 window.location.href='hello.html'; // 以下方式定时跳转 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)
Fixfox
<script language="javascript" type="text/javascript"> var second = document.getElementByIdx_x('totalSecond').textContent; setInterval("redirect()", 1000); function redirect() { document.getElementByIdx_x('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.getElementByIdx_x('totalSecond').innerText = "my text innerText";
} else{
document.getElementByIdx_x('totalSecond').textContent = "my text textContent";
}
</script>
5)整合
<span id="totalSecond">5</span> <script language="javascript" type="text/javascript"> var second = document.getElementByIdx_x('totalSecond').textContent; if (navigator.appName.indexOf("Explorer") > -1) { second = document.getElementByIdx_x('totalSecond').innerText; } else { second = document.getElementByIdx_x('totalSecond').textContent; } setInterval("redirect()", 1000); function redirect() { if (second < 0) { location.href = 'hello.html'; } else { if (navigator.appName.indexOf("Explorer") > -1) { document.getElementByIdx_x('totalSecond').innerText = second--; } else { document.getElementByIdx_x('totalSecond').textContent = second--; } } } </script>
