Subclassing JSObject
Locked
 
|
'ello. I'd like to use the Seaside javascript facilities to instantiate a javascript class of mine.
What I'd like is an example or something, because looking at the Seaside code and the jQuery classes and stuff is rather confusing. My class is simple, however. Basically, all I need is to instantiate a variable: x = MyClass(); and evaluate some setters: x.setVar('blah'); and then evaluate x.update(); on an interval... which JSObject provides. Thanks, RS _______________________________________________ seaside mailing list [hidden email] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside |

Hi Robert,
The obligatory first question: Do you really need to write it using Seaside's JSObjects? In other words: is there a reason not to use a plain javascript string or even an external javascript file? But here are the samples you requested. I would never write them like that unless you want to integrate such statements in seaside-generated javascript. (JSStream on: 'x') assign: ((JSStream on: 'MyClass') apply: #()) (JSStream on: 'x') call: 'setVar' withArguments: (Array with:'blah') ((JSStream on: 'x') call: 'update') timeout: 100 Hope it helps!

Thanks Johan, I appreciate it.
It is partially a learning exercise ;) In truth I could just do some string concatenation... I just need to set a bunch of things up front.

In reply to this post by Johan Brichau-2
Am I correct in calling the JSObject this way through a render method?
html document addLoadScript: (AJSObjectSubclass context: html). Then the code gets called in #javascriptContentOn:?
