Re: add javascript after AjaxLazyLoadPanel finishes rendering - (was: onAfterRender called twice in AjaxLazyLoadPanel)
Thanks Sven, that works nicely.
Now if only the iframe this panel loads in was in was being resized
appropriately after the panel loads its contents

Re: add javascript after AjaxLazyLoadPanel finishes rendering - (was: onAfterRender called twice in AjaxLazyLoadPanel)
If it was my own Panel class then I would add the extra markup. But I am using
the built in AjaxLazyLoadPanel class and was hoping to just override it easily.
Looks like I'll extend it as per Sven's suggestion below.

Re: add javascript after AjaxLazyLoadPanel finishes rendering - (was: onAfterRender called twice in AjaxLazyLoadPanel)
Ah. Ok added that, still nothing. I see in the markup that the html has been
added to the panel's div, though it's not running. Elsewhere on the page
Javascript is working ok so I don't think it's broken, I just don't think the
onLoad event is firing for an AjaxLazyLoadPanel.
I'll keep going with these behaviours though, if thats how it should be
implemented?
cheers for the tips,
Steve

Re: add javascript after AjaxLazyLoadPanel finishes rendering - (was: onAfterRender called twice in AjaxLazyLoadPanel)
I guess doesn't need to extend AjaxBehaviour as it doesn't have any ajax.
Try.
add(new AbstractBehavior() {
@Override
protected void onComponentTag(ComponentTag tag) {
super.onComponentTag(tag);
String js = "alert('hello');";
tag.put("onload", js);
}
}

Re: add javascript after AjaxLazyLoadPanel finishes rendering - (was: onAfterRender called twice in AjaxLazyLoadPanel)
I was looking at the first box.
add(new AbstractDefaultAjaxBehavior() {
@Override
protected void onComponentTag(ComponentTag tag) {
super.onComponentTag(tag);
String js = "alert('hello');";
tag.put("onload", js);
}
}

Also I can see the markup is being added to the end of the page after the
closing HTML. However, the Javadocs say it is meant to be called after
after the actual component is finished rendering. So it look s like
onAfterRender is not what I need.
Can I attach to a different phase in the render lifecycle to call the
javascript when that specific panel has just finished rendering?

Re: add javascript after AjaxLazyLoadPanel finishes rendering - (was: onAfterRender called twice in AjaxLazyLoadPanel)
Typo in the alert, but even adding logging to the AjaxEventBehavior, it never
fires.
.add(new AjaxEventBehavior("onload"){
protected void onEvent(AjaxRequestTarget target){
log.error("*");
target.appendJavascript("alert('hello');");
}
}));
logs show nothing.
Is it because its loading asynchronously after the rest of the page loads? If
so, how can I tap into it?
cheers.

perhaps you should keep a boolean flag that marks if you rendered the
js yet or not.
alternatively you can add a behavior to the panel with istemporary() {

Re: add javascript after AjaxLazyLoadPanel finishes rendering - (was: onAfterRender called twice in AjaxLazyLoadPanel)
Hi Lionel,
Thanks and yes, thats what I am trying to do, attach some javascript after
something has rendered. So I attached an AjaxEventBehaviour to it and now have
this:
add(new AjaxLazyLoadPanel("myPanel") {
@Override
public Component getLazyLoadComponent(String markupId) {
return new SomePanel(markupId);
}
}.add(new AjaxEventBehavior("onload"){
protected void onEvent(AjaxRequestTarget target){
target.appendJavascript("alert('hello)';");
}
}));
but the javascript is never fired.
Any more ideas?
cheers,
Steve

Hi Steve,
Are you trying to do this..
http://cwiki.apache.org/WICKET/adding-javascript-from-wicket.html
with an onload event instead of onblur, or do I misunderstand.

Re: onAfterRender called twice in AjaxLazyLoadPanel
So overriding onAfterRender for a component doesn't just override it for that
instance of the component?
Also I can see the markup is being added to the end of the page after the
closing HTML. However, the Javadocs say it is meant to be called after after
the actual component is finished rendering. So it look s like onAfterRender is
not what I need.
Can I attach to a different phase in the render lifecycle to call the
javascript when that specific panel has just finished rendering?
thanks,
Steve

Re: onAfterRender called twice in AjaxLazyLoadPanel
you are writing out javascript after every component render...
perhaps you should keep a boolean flag that marks if you rendered the
js yet or not.
alternatively you can add a behavior to the panel with istemporary() {
return true; }

onAfterRender called twice in AjaxLazyLoadPanel
I have an AjaxLazyLoadPanel and want some javascript to fire after its loaded
it's contents:
I assumed I could override onAfterRender and add my javascript like so:
add(new AjaxLazyLoadPanel("myPanel") {
@Override
public Component getLazyLoadComponent(String markupId) {
return new SomePamel(markupId);
}
@Override
protected void onAfterRender() {
JavascriptUtils.writeJavascript(getResponse(),
"alert('hello');");
super.onAfterRender();
}
});
Except it is called twice, it looks like once when the page is loading and then
again when the actual panel has been loaded.
Is there another way to achieve what I want?
thanks,
Steve
