[Seaside] Re: String concatenation in javascript

[Winfried Jacobs]

Hello Dave,

with a little extra method in JSObject (*) you could even write it completely in
Smalltalk:

   html anchor
       onClick: (
           (html jQuery id: 'textAreaId') value: (
               html jQuery id: 'textAreaId') value + 'some text'
               );
       with: 'a label'.


(*) Method #+ in JSObject defined like this:

+ anObject
    "Combine the receiver and anObject with a plus sign"

    self addDecoration: (JSBinary new operator: '+'; statement: anObject)


Best regards
Winfried
