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>
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>
4) 解决Firefox不支持innerText的问题
<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>
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>
