Pressing enter does real submit?

bkyrlach Aug 8, 2008 8:08 PM

I've got a really simple JSF form with one h:inputText and one a:commandButton designed to do an ajax submit. However, when I type text into the input field and press the return key, it does a full, non-ajax post-back to the page. This behaviour is even evident in the live demo page here...

Is there a way to work around this behaviour?

Thanks.

One possible way:

1. Capture this event with defining onkeypress attribute
2. Detect that ENTER is pressed.
If so:
3. Invoke Ajax request for this form using a4j:function
4. Return false to avoid non-Ajax request

In general, this question is pretty popular. Search in Google for submit form enter keywords for details

Why define an a4j:function instead of just having it call the a4j:commandButton's click function? I guess I was just a little suprised in general that I have to explicitly click the commandButton to get an ajax request.

You can click a button from javascript if all browser that you have to support allow such call.
