Html 定时任务

10秒自动跳转

<script type="text/javascript">  
var i = 10;  
function remainTime(){  
    if(i==0){  
        location.href='<%=path%>';  
    }  
    document.getElementById('endtime').innerHTML=i--;  
    setTimeout("remainTime()",1000);  
}  
remainTime();  
</script>  

setInterval()循环执行相应的方法

 <script type="text/javascript">
      setInterval("myInterval()",1000);//1000为1秒钟
      
       function myInterval()
       {
            alert('aaaaaaaaa');
        }
 </script>
