Cancel Button

The (WACancelButtonTag) cancel button in a form with required fields (html 5) still requires the fields to be filled out when canceling hehe. Is this normal?

To my understanding (and I am a newbie):
1. All callbacks are valued before rendering components
2. Callback processing is not done if a high priority callback cancels further
processing via `self handleAnswer: false`.
3. Callback processing is also cancelled by #respond processing.
The WACancelButtonTag is set to high priority (-5). In my opinion you can cancel
further processing of callbacks (and validation) by setting
`self handleAnswer: false.`.
Watch out if you also have AJAX as to my understanding also has priority -5.

Re: Cancel Button

Well, that's not really relevant. If you have a required field (html 5) you'd think that cancelling would still work.

You mean the browser still validates them? Well it's kinda expected.
There is no cancel button in HTML so we just use a normal one and do
callback trickery. Unfortunately the browser doesn't know about this.
A possible fix might to to set the novalidate property on the form
when the button is pressed.

Cheers

Could one add some onClick javascript on a "cancel" button to set
everything to disabled? I have a large textArea that I set to readonly
because I don't want it changed but I want the user to be able to copy (and
then paste) from it. I then use javascript to disable it on a submit (or
cancel) so the browser won't send it back to the server, to save the upload
time.

I am puzzled at your 'not relevant' posting. In my opinion, when you cancel, the
fields should not be deemed required.

There is no cancel button in HTML5, only in Seaside. The browser
doesn't know it's a cancel button. Therefore you have to write some
JavaScript that either removes the required property from the input
fields or adds the novalidate property to the form.

Right. Or use a link styled to look like your buttons instead of a button.

Sorry Fritz, I appreciate the info. My intent was to steer the conversation a little different way. Philippe's response provided the solution I was looking for:

Therefore you have to write some
JavaScript that either removes the required property from the input
fields or adds the novalidate property to the form.

Thanks,
