        var user = "all";
        alert(user)
    }
</script>
</asp:Content>

Use this code to close alert without refreshing page

<script type="text/javascript">
    window.onbeforeunload = function() {
        return ;
    }
</script>

The "default event" is occurring.

To disable it, use return before you function call as follows:

<button runat="server" onclick="return calling()">

And in the function:

<script type="text/javascript">
   function calling() {
       var user = "all";
       alert(user);
       return false;
   }
</script>
