1、用html实现
<meta http-equiv="refresh" content="10"><!-- 每10秒刷新一次页面 -->
<meta http-equiv="refresh" content="10;url=index.html"><!-- 10秒后跳转到指定链接 -->
2、用javascript实现
<script language="javascript" type="text/javascript"> window.location.href='index.html';// 直接跳转 </script>
<script language="javascript" type="text/javascript"> setTimeout("javascript:location.href='index.html'", 5000);// 5秒后跳转 </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、带倒计时的javascript实现方法(IE 浏览器)
<span id="totalSecond">5</span><!-- 5秒后跳转 --> <script language="javascript" type="text/javascript"> var second = totalSecond.innerText; setInterval("redirect()", 1000); function redirect(){ totalSecond.innerText=--second; if(second<0) location.href='index.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)
4、结合了倒数的javascript实现(firefox 火狐浏览器)
<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 = 'index.html'; } </script>
5、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>
6、该方法对上面的3和4进行了整合
<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 = 'index.html'; } else { if (navigator.appName.indexOf("Explorer") > -1) { document.getElementById('totalSecond').innerText = second--; } else { document.getElementById('totalSecond').textContent = second--; } } } </script>
