Hi Adr,
The markupid of any component is only assigned when the containing
component is actually added into the page.
The way around this is that the AttributeModifier (and most other
behaviours I believe) class actually renders the "onclick" event during
the onComponentTag(..) method of the panel being rendered at which point
the markup id's are set.
You can just wrap the javascript in a model that will generate the
correct text string when getObject() is called.
My helper class for this case takes in a string and replaces a
placeholder with the desired markupid when the getObject() method of
IModel is called.
e.g. panel.add (new AttributeModifier ("onClick", new
MarkupIDInStringModel ("var panel=document.getElementById('" +
MarkupIDInStringModel.MARKUP_ID_PLACEHOLDER +
"');panel.style.display=this.checked?'block':'none';", addLocationPanel));
so when the onComponentTag method is called the model inserts
addLocationPanel.getMarkupID() into the placeholder value.
Regards,
Mike
I have moved my objects in Pnale to fields eg.:
public class RegisterUserPanel extends Panel {
final CheckBox openClosePanelCheckBox;
final Panel addLocationPanel;
...
}
and from Page I setup attributes:
RegisterUserPanel registerUserPanel = new
RegisterUserPanel("register_user_panel");
add(registerUserPanel);
registerUserPanel.openClosePanelCheckBox.add(new
SimpleAttributeModifier("onclick", "var
panel=document.getElementById('" +
registerUserPanel.addLocationPanel.getMarkupId() +
"');panel.style.display=this.checked?'block':'none';"));
But is this good way to follow? Any other pattern to use?
best regards,
Adr
