[Seaside] how to render access to a JS argument variable?

Hi Chris,

You are right, I was looking at the wrong places and responded too quickly.

True, but that will break the most common use of those methods: passing in a Smalltalk block or a Seaside component (i.e. any Renderable).

Somehow, your use case has never popped up before, but it’s interesting to see if we could make that work.
The JSObject>>render:on: is used when the script is actually rendered in the html, so it seems difficult to change it there.

Instead of ommitting the call to #render: from #replaceWith:, I’m guessing a different method needs to be introduced which renders any renderable but does nothing with a JSObject.
We can try...

> #html:, #prepend:, #replaceWith:, #wrap:, #wrapAll:, #wrapInner: all
> have that (self render: aRenderable) which forces the String arg...


If I understand what you are trying to do in the example snippets, the typical way we would write this in the Seaside binding is like this:

(html jQuery id: buttonId) onClick: (html jQuery ajax script: [:s | s << ((s jQuery id: replacementId) replaceWith: resultWidget) ])
