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<spanid="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'）<spanid="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>新闻热点
