Conditionally include header item when page contains ajax components
Hi all,
I have a base page from which all my pages inherit. I want to conditionally
include a javascript reference (header item) if the page contains an ajax
component. The reference is a veil implementation based on BlockUI which is
redundant (and also causes a javascript error) if the page has not ajax
(and hence JQuery is not loaded).
Any suggestions?
Thanks
Marios

The javascript will only be included if your Ajax enabled component is
included that in turn references the JS ResourceReference, otherwise it
wont be.

Re: Conditionally include header item when page contains ajax components
Posted by Nick Pratt <nb...@gmail.com>.
Understood.
Martin - (for my own curiousity now) would it be possible and would there
be any benefit to replacing the default Wicket jQuery resource reference
with a custom veil.js ResourceReference that also included the packaged
Wicket jquery resource ref as a dependency (i.e. configure this all in
Application.init() )?

Re: Conditionally include header item when page contains ajax components
Posted by Marios Skounakis <ms...@gmail.com>.
I probably wasn't clear enough.
Here's my case:
BasePage.renderHead() adds veil.js as javascript resource reference.
All my pages inherit from BasePage. But veil.js is only useful when a page
has wicket ajax.
If I declare that veil.js has a dependency on jquery then the result is
that all pages get both veil.js and jquery. What I want is that pages that
don't have ajax (i.e. no Wicket-Ajax or Wicket-Event libraries) don't
include veil.js. I could do it on a per component basis but this would be
cumbersome and error prone. So instead I used Martin's solution and
conditionally render veil.js only if the headerResponse renders
Wicket-Event.

Re: Conditionally include header item when page contains ajax components
Posted by Nick Pratt <nb...@gmail.com>.
Then you're doing something odd :-)
If you have dependencies like this:
CustomComponent --> Custom JS Reference (and this is added in the public
void renderHead( Component component, IHeaderResponse response ) method)
--> Wicket's JQuery JS Reference
Page A (no Ajax components or components depending on Wicket's jquery ref)
Page B --> CustomComponent (Page B being a copy of Page with a single
instance of your CustomComponent)
When you load Page A, the JS will not be loaded.
When you load Page B, both the Wicket JS and the custom JS will be added to
the page.
If you are seeing Jquery being loaded in Page A then some component on that
page requires the Wicket JS libraries and is causing it to be added.

Thanks Martin, this worked well.
Sebastien and Nick, I tried the solution with JQueryPluginResourceReference
but this indeed caused JQuery to be loaded in non ajax pages.

Hi,
You can create custom IHeaderResponseDecorator and by using custom
IHeaderResponse you can check for contributions
of org.apache.wicket.ajax.WicketAjaxJQueryResourceReference
See
http://www.wicket-library.com/wicket-examples-6.0.x/resourceaggregation/?0
and http://wicketinaction.com/2012/07/wicket-6-resource-management/

Re: Conditionally include header item when page contains ajax components

If I'm not mistaken this will cause JQuery to be included whenever my js
reference is included. Effectively this will cause non-ajax pages to load
javascript which applies only to ajax requests.
What I want is the opposite: to not include my js reference when the page
does not have any ajax.

oops, seems that one "IMO" is enough...

Hi Marios,
IMO the best way IMO is to make your js reference extending
JQueryPluginResourceReference (wicket 6)
Best regards,
Sebastien.
