hi,
we're using a home-grown wrapper for integrating jquery into wicket -
specifically for jquery effects.
and i'm having some trouble with ajax updates. i'll explain with an example:
final WebMarkupContainer listOfCommentsContainer = new
WebMarkupContainer("listOfCommentsContainer");
listOfCommentsContainer.setOutputMarkupId(true);
add(listOfCommentsContainer);
AjaxLink<Void> numberOfCommentsLink = new
AjaxLink<Void>("numberOfCommentsLink") {
@Override
public void onClick(AjaxRequestTarget target) {
target.addComponent(listOfCommentsContainer);
}
};
listOfCommentsContainer.add(new JQueryEffectBehavior(new
SlideToggleEffect(), numberOfCommentsLink));
add(numberOfCommentsLink);
this code is basically outputting something like:
<script type="text/javascript" ><!--/*--><![CDATA[/*><!--*/
Wicket.Event.add(window, "domready", function() {
$('#numberOfCommentsLink24').click(function() {
$('#listOfCommentsContainer25').slideToggle(450); }) ;});
/*-->]]>*/</script>
listOfCommentsContainer25 being the target container to slide,
numberOfCommentsLink24 the trigger.
this works fine per se. now when i click on numberOfCommentsLink24 ,
my list is refreshed (added it to the ajaxrequesttarget) and the
effect behaviour outputting javascript code again...
<ajax-response><header-contribution><![CDATA[<head
xmlns:wicket="http://wicket.apache.org";><script type="text/javascript"
src="resources/hub.app.wicket.components.jquery.JQueryResourceReference/jquery-1.2.6.js"></script>
<script type="text/javascript"
src="resources/hub.app.wicket.components.jquery.JQueryEffectCoreResourceReference/jquery-1.2.6.effects.core.js"></script>
</head>]]></header-contribution>
(...)
<evaluate><![CDATA[$('#numberOfCommentsLink24').click(function() {
$('#listOfCommentsContainer25').slideToggle(450); })
]]></evaluate></ajax-response>
which means that i can visually perceive a very quick slideDown
followed by a slideUp (this is the normal slideToggle functionality).
is there a way not to include the <evaluate> part? or detect if the
component has already been rendered in markup to check whether to
execute the behaviour again?
perhaps i'm missing some basic point here... any suggestions?
thanks in advance,
francisco
