Hi,
I have a class of links where some of them sometimes shall not
trigger. The decision is made server-side according to current state.
At first sight, the realization seems to be not that straight forward:
-- I add an AJAX behavior to these link that allows default action
and computes if the link action shall be prevented.
-- The AJAX behavior has an AJAX call listener (complete handler)
that may call attrs.event.preventDefault() if the link shall
not be triggered.
-- The decision if the link shall not be triggered is
communicated by the AJAX request to the complete handler via
an HiddenField that is updated in the AJAX request. Delivery
of the decision via JSON is difficult, as we also want to
update other DOM elements with the response (feedback why the
link was not triggered).
Do I miss something? Is there a completely different approach that
I could take?
Or: Is there a better way to communicate the decision if the link
shall be triggered to the call listener? Introducing a hidden field
for that purpose seems to be awkward, for me.
I would be thankful for any comments or recommendations.
Joachim
