> You can use the jQuery binding in Seaside to easily return javascript

> html

>         onClick: (html jQuery ajax callback: [:value | Transcript show:
> value ] value: (html javascript call: ‘test’ withArguments: #()))
>         with: ‘Call test’

I tried this but it doesn't work, nothing appeared in the Transcript like
if the callback isn't triggered...
Maybe I forget something in the configuration of application
(WAAdmin register: self asApplicationAt: 'Test')
        addLibrary: JQDevelopmentLibrary;
        addLibraby: MyLibraryWithJsFiles

MyLibraryWithJsFiles contains just a js file with test() { return true; }

> The #callback:value: method passes the result of client-side expression to

> Mind that (as the method comment states), this only works for single
> literal Javascript object (String, Number, Boolean). If you want to pass
> more complex result values, you can use #callback:json: or write your own
> serialization if json serialization is not sufficient either.
> Hope this answers your question,

Thanks for your help,
