Re: wrapping onclick in AjaxLink with 1.5.4
Hi Martin,
I'm following the example
https://cwiki.apache.org/WICKET/calling-javascript-function-on-wicket-components-onclick.html
shown here . My code is literally that, added to the prototypical Wicket
Quickstart HomePage.java:
public class HomePage extends WebPage {
private static final long serialVersionUID = 1L;
public HomePage(final PageParameters parameters) {
add(new Label(version,
getApplication().getFrameworkSettings().getVersion()));
AjaxLink ajaxLink = new AjaxLink(ajaxLink) {
@Override
public void onClick(AjaxRequestTarget target)
{
System.out.println(onClick fired);
}
protected IAjaxCallDecorator getAjaxCallDecorator() {
return new AjaxCallDecorator() {
public CharSequence decorateScript(CharSequence script)
{
return alert('This is my javascript call'); +
script;
}
};
}
};
add(ajaxLink);
}
}
If I inspect the generated HTML, it looks like this:
# This is an ajax link.
Thanks for your time.

Put @Override on the line above and you will see that the compiler complains.
Please update the wiki with the new signature for 1.5
{
return alert('This is my javascript call'); +
script;
}
};
}
};
add(ajaxLink);
}

Re: wrapping onclick in AjaxLink with 1.5.4
Well that was simple, thank you. I'm pedantic enough to have added @Override to the getAjaxCallDecorator(), but I missed decorateScript() in my initial attempt. The method is being called now, and I have updated the Wiki. However the second example listed on the Wiki (AttributeAppender) also does not work. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/wrapping-onclick-in-AjaxLink-with-1-5-4-tp4430306p4431489.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

It is not possible to add several behaviors on the same component that manipulate the same attribute. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/wrapping-onclick-in-AjaxLink-with-1-5-4-tp4430306p4431489.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org -- Martin Grigorov jWeekend Training, Consulting, Development http://jWeekend.com - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
wrapping onclick in AjaxLink with 1.5.4
Hi, I need to run some Javascript on the client when the user clicks an AjaxLink. I'm following https://cwiki.apache.org/WICKET/calling-javascript-function-on-wicket-components-onclick.html these instructions , but my onclick() javascript always gets overwritten by the AjaxLink's behavior. I tried overriding getAjaxCallDecorator() as well as adding an AttributeAppender, and neither seem to work. Nor does adding the appender in onInitialize(), as http://apache-wicket.1842946.n4.nabble.com/AttributeModifier-and-AjaxLink-in-1-5-td3830027.html this thread recommends. Thanks for any advice. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/wrapping-onclick-in-AjaxLink-with-1-5-4-tp4430306p4430306.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: wrapping onclick in AjaxLink with 1.5.4
Hi, You need to override AjaxLink's #getAjaxCallDecorator(). With it you can add you script to be executed before or after the real script that will call AjaxLink#onClick. Show some code if you still cannot manage it. On Wed, Feb 29, 2012 at 4:14 AM, armhold armh...@gmail.com wrote: Hi, I need to run some Javascript on the client when the user clicks an AjaxLink.
