AjaxEventBehaviour on page onload

[drf]

I wonder if anyone can help with the following:
I've added this code to a the constructor of a WebPage:

this.add(new AjaxEventBehavior(onload) {

@Override
protected void onEvent(AjaxRequestTarget target) {
System.out.println( IN on-LOAD);
}
});

Am expecting the event to be called when the page loads, but it is not.
Here is the snippet for the page head:



VCF



Any ideas are appreciated!

You can implement an IHeaderContributor:

Ajax like event for onLoad

[Brown, Berlin [GCG-PFS]]

I am using the Ajax Tabbed Panel class and I could possibly hijack the
onUpdate/onClick routines to suit my needs. 
 
But I was curious, is there an event/behavior  that I can call when a
panel loads or render.
 
Something along the lines of:
 
SomeAjaxPanel {
  onBeforeRender() {
this.add(AjaxBehavior(onload') {
  onEvent(target) {
 
  }
   }
  }
 
}

Hi,

Newbee question: I need to add the onload attribute to the body tag (I
can't use other methods to accomplish the same thing...)

My html:
html xmlns=http://www.w3.org/1999/xhtml;
xmlns:wicket=http://org.apache.wicket.sourceforge.net/; 
wicket:head
...
/wicket:head
wicket:extend
body wicket:id=bodyElement
...
/body
/wicket:extend
/html

Java:
WebMarkupContainer body = new WebMarkupContainer(bodyElement);

add(new WebMarkupContainer(bodyElement) {
�...@override
 public boolean isTransparentResolver() {
   return true;
 }
�...@override
 protected void onComponentTag(final ComponentTag tag) {
   super.onComponentTag(tag);
   tag.put(onload, onload(););
 }
});

Result html:
html
head
...
/head
body
body onload=onload();
...

I now have two body start tags.
The code below results in a runtime exception stating that bodyElement
was not declared..

body wicket:id=bodyElement
wicket:extend
...
/wicket:extend
/body
/html

I have also tried adding:
add(new BodyTagAttributeModifier(onload, true, new Model(onload();), this));

But nothing gets added to the body tag.

Can someone direct me in the right direction?

Yeah, I actually messed up the behaviour because I never noticed the
rendOnLoad method.

I've done as you suggested in the behaviour and then simply added that to
the component.  It works perfectly, thanks Martin.


The progression to more advanced Wicket certainly requires more web specific
knowledge that Wicket has shielded me from in the past :)

body-tag onLoad/onScroll

[Dr. Wolf Blecher]

Hi all,

I have the following situation:
I want to add a java script function call to the body tag which get's as
parameter the id of a wicket panel:

body onload=javascript: initPosition('sidebarRightSelection65');
onscroll=javascript: sideBarRightPos('sidebarRightSelection65');

So I tried the following:

add(new BodyTagAttributeModifier(onload, true, new Model(javascript:
initPosition(' + selection.getMarkupId() + ');), selection));

I also let the Panel implement the IHeaderContributor Interface but this did
not work either.

Neither way worked.

What I want to basically achieve is that if the element is scrolled out of the
page, its style will be set to fixed, so that keeps shown. I have a javascript
function for this, but this function needs the id of the element.

Any hints?

Cheers

Wolf

Make body a regular Wicket component: body wicket:id=theBody
Then in .java:
WebMarkupContainer body = new WebMarkupContainer(theBody);
body.add(new (Simple)AttributeModifier())

afair body is no more special element.

Re: body-tag onLoad/onScroll

And in that webmarkupcontainer, override istransparentresolverand return
true.
That will allow you to add components directly to the page without having to
add them all to the body's web markup container.

Addendum to my last:
Apparently the simple alert case *is* working in Safari 3.2.1 but *is  
not* in Firefox 3.0.6.


This suggests to me that the script has not been updated for Firefox,

Re: onLoad never fires -- is there a bug in 1.4?

I wonder if this is related to a bug that was fixed in firefox 3.0.6...

https://bugzilla.mozilla.org/show_bug.cgi?id=444322
Firefox 3 onload and DOMContentLoaded event firing before the page is 
fully loaded


We experienced that problem with Firefox 3.0.5 made a work around for 
it, and then 3.0.6 arrived and fixed it
But there is another bug mentioned in comment #72 
https://bugzilla.mozilla.org/show_bug.cgi?id=444322#c72 which might be 
similar to this problem (even mentions using an alert will cause the 
problem to appear)

Hmm... that could be related.

For the moment I've worked around it in a somewhat kludgy way, but I  
plan to go back and try again with a cleanroom test app as soon as I  
have some time to look into it more.

onLoad javascript event with Markup inheritance

[itayh]

Hi,

I use Markup inheritance in my site in order to keep common logic in the
base page. 
I would like my child pages to do certain javascript actions when they are
loaded. I try to define the the javascript on the childs body (between the
wicket:extend and /wicket:extend) but I don't see them in the generated
page (the base + child page). Any Idea how to generate onLoad javascript
action for child page?

Re: onLoad javascript event with Markup inheritance

[Ernesto Reinaldo Barreiro]

Something like:

HTML

wicket:extend   script wicket:id=script
type=text/javascriptalert('Hi');/script
  .
/wicket:extend

Java code:

Label script = new Label(script, new ModelString()) {
private static final long serialVersionUID = 1L;

@Override
protected void onComponentTagBody(MarkupStream markupStream, ComponentTag
openTag) {
StringBuffer sb = new StringBuffer();
sb.append(var );
// some more Javascript code...
replaceComponentTagBody(markupStream, openTag, sb.toString());
}
};
addOrReplace(script);

does not work? I use that kind of things for panel and works just fine...
That should also work for extend...

Best,

Ernesto

Re: onLoad javascript event with Markup inheritance

you should implement the IHeaderContributor interface in your page and 
use IHeaderResponse.renderOnLoadJavascript() method in the 
implementation of the renderHead method..

You can use wicket:head or HeaderContributors.

Re: onLoad javascript event with Markup inheritance

that would be a cleaner solution, indeed... but normally I use at most a
couple of pages and lot of  panel replacements so each component just
contributes what it needs...

Hello,

Is it possible to contribute to the body html tag from within

Thanks in advance.

About Wicket portlets, DatePicker, onLoad and onDomReady

[Serkan Camurcuoglu]

Hi all,
While I was experimenting with date pickers in portlets, I've noticed 
something. When a portlet makes a header contribution, it cannot 
directly contribute to document's head, instead it generates something like:


script type=text/javascript 
src=/subscriber-web/buyOffer/ps:P-11c703e086b-1/resources/org.apache.wicket.extensions.yui.YuiLib/yuiloader-beta.js/script
script type=text/javascript 
src=/subscriber-web/buyOffer/ps:P-11c703e086b-1/resources/org.apache.wicket.markup.html.WicketEventReference/wicket-event.js/script
script type=text/javascript !--/*--![CDATA[/*!--*/


in the page body. Here P-11c703e086b is the portlet's id, and each 
portlet fragment on the page has a different id, and hence they load 
different javascript files (from the browser's point of view). So now, 
when I have two instances of the same portlet which contains date 
pickers, they both include their own wicket-event and yuiloader 
javascript files. The result of this is that only the date pickers in 
the second (last loaded) portlet work, and the date pickers in the first 
portlet do not work. I think that the global javascript objects from the 
last loaded file override the ones from the first (such as Wicket and 
YAHOO objects).


However, I've noticed that (while developing a different javascript 
behaviour for myself), if I execute the required javascript code during 
the onLoad event (instead of the onDomReady event), all of the date 
pickers work as expected. I have confirmed this by modifying the 
DatePicker class and using it within my portlets.


Does anybody have an explanation for this? I know that using onLoad is 
bad, but it seems to solve my problem..


(BTW I'm using wicket 1.3.4 and Jetspeed 2.1.3)

Best regards,

SerkanC

Re: body onload contribution

[John Patterson]

Something I have noticed with renderOnLoad with my site is that it  
stopped being called after I added some Javascript for banner ads.   
Maybe their included script replaced the wicket function.  I had to  
revert to using onLoad which makes gives the impression that the maps  
load more slowly.


I have been thinking about creating a panel to include at the bottom  
of the page that renders scripts etc.  Anyone tried something like this?
