If you have a method like this:

renderOn: html
	html addLoadScript: (self someScript)

and you invoke it in an ajax request like this:

(html jQuery id: #id) load html:[:r | self renderOn: r ].

Then the script generated in ‘someScript’ will be executed when the html is loaded on the page.
Seaside adds the loadscripts explicitly to the rendered html as script tags that get executed by jQuery when loaded in an ajax request.

You can also do it ‘manually' like this:

(html jQuery id: #id) load html:[:r | 
	self renderOn: r. 
	r script: self someScript ].

Which is actually the same, just less convenient.

Is this what you are looking for? Can you share an example where it does not work or fit your needs?

cheers!
Johan
