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>
复制代码
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
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>
复制代码 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>
复制代码 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>
复制代码 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>
