[Seaside] Read two values ( width @ height ) with only one declaration

[Johan Brichau]

You will need to construct a valid javascript expression in the argument passed after #value:.
Alternatively, try using the #callback:json: method to transfer multiple values:

(html jQuery ajax
  	callback: [ :dict | dict inspect ]
   	json: (JSStream on: '{ "width": $(this).width, "height": $(this).height}')

Hope this helps
Johan
