推荐答案

if(Convert.ToInt32(Request.QueryString["mn"])>0)
            {
                Button1.Attributes.Add("onclick", "confirm('Are you sure')");
            }

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

function unload()
    {

       var Flg= document.getElementById('hdn');
        if (parseInt(Flg.value)>0)
        {
            event.returnValue = "Are u sure to close this page";
        }
    }
</script>

<body  onbeforeunload="unload()" onload ="AutoSave()"  >
