  1.3秒后自动返回

  

复制代码 代码如下:

  <span id="totalSecond">3</span>秒后自动返回

  <script language="javascript" type="text/javascript">

  <!--

  var second = document.getElementById('totalSecond').textContent;

  if (navigator.appName.indexOf("Explorer") > -1) //判断是IE浏览器还是Firefox浏览器,采用相应措施取得秒数

  {

  second = document.getElementById('totalSecond').innerText;

  } else

  {

  second = document.getElementById('totalSecond').textContent;

  }

  setInterval("redirect()", 1000); //每1秒钟调用redirect()方法一次

  function redirect()

  {

  if (second < 0)

  {

  location.href = 'http://www.baidu.com';

  } else

  {

  if (navigator.appName.indexOf("Explorer") > -1)

  {

  document.getElementById('totalSecond').innerText = second--;

  } else

  {

  document.getElementById('totalSecond').textContent = second--;

  }

  }

  }
