定时刷新页面

 

 <!-- 定时刷新 start-->
 <script type="text/javascript">

var time=30;
function delay()
{ 

    if(time>0)
        {
            document.getElementById("reflash").innerHTML=--time+"秒后自动刷新页面";
        }
    else
        {
            
             missedOrderForm.action = "getNotAcceptedWorkOrderSelect.action";
             missedOrderForm.submit(); 
        }

}
var setTime=setInterval("delay();",1000); 


</script>  
<!-- 定时刷新 end-->

子页面开窗之后也会刷新页面的解决

if(!!setTime) {
              clearInterval(setTime);
              setTime = null;
            }
