5秒跳转到指定页面

1,对应得脚本。

<script type="text/javascript">     
                 function skip(sec,url){     
                       
                            document.getElementById("to").innerHTML=sec+"秒后自动跳转";     
                            if(sec==0) 
                             document.getElementById("to").innerHTML="正在转入...";    
                       if(--sec>=0){     
                            setTimeout("skip("+sec+",'"+url+"')",1000);     
                                     }     
                       else{       
                            location.href=url;     
                            }     
                         }     
 </script> 

2.html代码，<%=url%>为将要跳转的url。

 

<div> 
                <a href="<%=url%>"><span id="to">5秒后自动跳转</span>到指定页面.如果没有自动转入，也可以手动转入.</a> 
               <script type="text/javascript">skip(5,'<%=url%>');</script> 
                   </div>
