[Tobago] f:ajax inside tc:in event="keyup"

["jfrm.maurel@gmail.com" <jf...@gmail.com>]

Hi,

I would like to check whether a user entry is a valid e-mail address 
each time a key is pressed.

When I use f:ajax with event="keyup" inside tc:in, Tobago complains that 
this event is not valid. It seems like this event is not implemented.

   <tc:in id="username" value="#{loginController.username}" label="User" 
focus="true">
    <f:ajax event="keyup" listener="#{loginController.checkMel}" />
   </tc:in>


Is there a workaround for this ?

Regards.

Hi,

Tobago doesn't currently support the 'keyup' event.
We plan to implement this in the future but in the meantime you have to
use the 'change' event.

If 'change' is absolutely not an option, the only workaround I see is a
JavaScript-Hack.
You can put a listener on 'keyup' and trigger the 'change' event.
Something like this:

function() {
  var $inputAjaxField = jQuery("#page\\:mainForm\\:inputAjax\\:\\:field");
  $inputAjaxField.on('keyup', function () {
    $inputAjaxField.trigger('change');
  });
};

But I'm not sure what side effects will occur...


Regards,
Henning

I'm not sure about your question, is it about the behavior of the
"onchange" event? I think this works like intended. It makes no sense to
fire this event at a text input on every keypress, even if each keypress
changes the content.

I see, I'm not sure if this is really the intended behaviour.

@Udo, Henning what do you think?

Hi,

the change event should work for your usecase. You'll find a sample at
the bottom of the page:
