Sven Haster updated WICKET-3961:
--------------------------------
Priority: Minor (was: Trivial)
> nextFocusedElementId to be added to the AjaxRequestHeaders (AjaxRequestTarget)
> ------------------------------------------------------------------------------
>
> Key: WICKET-3961
> URL: https://issues.apache.org/jira/browse/WICKET-3961
> Project: Wicket
> Issue Type: New Feature
> Components: wicket
> Affects Versions: 1.5-RC5.1
> Reporter: Sven Haster
> Priority: Minor
> Labels: ajax
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> I'd like to have a field/request header "nextFoxusedElementId" to be added to
> ajaxrequests (to be retrieved via AjaxRequestTarget.getNextFocusedElementId()
> ) so that I can append javascript to the ajaxrequest to manipulate the newly
> focused element.
> Example:
> Two textfields, A and B. I've added an ajax event behavior for the
> "onblur"-event to textfield A. Now when textfield A has focus and I then move
> focus to textfield B, wicket writes the id of textfield A to the ajaxrequest,
> saves the id of textfield B, removes focus from textfield B, handles
> ajaxrequest (including any and all javascript) and then refocuses textfield B.
> However, I want the text inside textfield B to be highlighted. I can append
> javascript to the ajaxrequest to do #textfieldB.select() and set
> focusComponent(null) on the AjaxRequestTarget but what if textfield B is not
> the newly focused component? What if the focus instead went to checkbox C,
> for instance? Since I don't know what element received the focus I can't
> check to see if it's textfield B. That's why I'd like to be able to request
> the newly focused component from the ajaxrequest.
> AFAICT, this shouldn't be too much work, since the id of the newly focused
> component is already saved, so it looks like it might just be a case of
> waiting for that save to be done. But maybe that is an oversimplification and
> is it quite tricky (or is the wait-time too long) to get the sending of the
> ajaxrequest to wait for the new component to receive focus.
