[Seaside] Fetching GET parameters from a Seaside component.

[Sebastian Sastre]

I'd use a js function installed in the (wrapper div of the) element that corresponds to the component. And that function will make a request that can run a normal seaside callback.

I use prototype so a function to change the state of the component (i.e: closing it) it would look like:


AnOpennableClosable>>beClosedFunctionOn: html 
	^ JSFunction new
		add: (html prototype request
				callback: [self beClosed ];
				yourself);
		yourself

But you want a value so you can use the request's callback:value: like this:

AnOpennableClosable>>beClosedFunctionOn: html 
	^ JSFunction new
		add: (html prototype request
				callback: [:val| someState := val] value: 'navigate.to().whereverTheValue[is]' asJSObject;
				callback: [self beClosed ];
				yourself);
		yourself

BTW, observing some custom event and make it react with that, is something that usually rocks

have fun
