js倒计时跳转

等待<span id="daojishi">10</span>秒后你将跳转到http://blog.163.com/qianw_ok/

<script type="text/javascript">

  function daoshu(){

     var djs = document.getElementById("daojishi");

     if(djs.innerHTML == 0){

          window.location.href='http://blog.163.com/qianw_ok/';

          return false;

     }

     djs.innerHTML = djs.innerHTML - 1;

}

  window.setInterval("daoshu()", 1000);

</script>
