My web page has a default button. The button disables itself after a click to prevent duplicate clicks. If the processing fails it enables again to allow a retry but the button no longer behaves like the default button (i.e. I can't press the enter key to activate it) after it has been enabled again. Is there a way to make it the default button again after being re-enabled?

Asynchronous JavaScript and XML (AJAX) is a group of interrelated Web development techniques used on the client-side to create asynchronous Web applications. With AJAX, web applications can send data to and retrieve from a server asynchronously (in the background) without interfering with the display and behavior of the existing page. HTML and CSS can be used in combination to mark up and style information. The Document Object Model (DOM) is accessed with JavaScript to dynamically display and allow interaction with the information presented.
