如何使用Enter键关闭Javascript Alertbox

Question

How to close Javascript alertbox by using the enter key..

function validate(){
     if (document.getElementById("<%=username.ClientID%>").value == "") {
         alert("Please select UserID.");              
         return false;
     }
}

Actually I'm using custom Alert like: Var msg=new alert(); This is not closing...

There is no way to control an alert() other than initially creating it. There are no events and no way of changing it once it is created. If you need more control, consider creating a modal dialog, for example with jQuery UI.
