Re: How to do Simple non-Ajax Javascript Behaviour?

I've followed Martin's hint and managed to get the event firing by adding an attribute modified to onkeyup to the textfield so I guess that's a solution. Thanks for that one.

Hi Martin,
Thanks for the hint, I'll look that up.
In fact, I could do onkeyup onto the markup on the html directly but
wanted to do it the wicket way =) as well as reliably obtain my markupid
without cluttering the my markups with JS all over the place.
On further investigation, using the approach described below I get
Wicket.Event.add(tagNo2f, "keyup", function(event) { alert('Key Up!');;});
Added in my page. This is done automatically. So it seems to be adding the
event to the event monitoring code. It's just not firing.
Did I miss out something obvious?

Hi,
Hmmm, I have a simple thing which should be easy but I just cant figure out
on Wicket.
1. I have an input box.
2. I need to "attach" a javascript to this box to monitor key presses.
Basically I need to fire a js on the keyup event.
I've googled but have not found the answer to a basically simple thing.
I've tried the following which I realise wont work since the rendering
should not be into the header (or should it?)
public class KeyPressTagBehavior extends AbstractBehavior
{
private static final long serialVersionUID = 262920170424255562L;
private Component component;
public void bind(Component component)
{
this.component = component;
component.setOutputMarkupId(true);
}
public void renderHead(IHeaderResponse iHeaderResponse)
{
super.renderHead(iHeaderResponse);
iHeaderResponse.renderOnEventJavascript(
component.getMarkupId(),
"keyup",
"alert('Key Up!')"); }
}
Then done a simple
TextField field = new TextField("somefield");
field.add(new KeyPressTagBehavior());
I realised that the renderHead will render into the head. But cant find a
reference in the API to let me add it into the TextField. What is the
correct way to do this?
Regards,
Lester
