[Seaside] capture client events in seaside?

[Robert Sirois]

The callback won't be executed until the select element is serialized (either via ajax or submission), so in order to get the currently selected value, you will need to serialize first.

| selectId |
You could try something like (untested):
html select         id: (selectId := html nextId);	list: Dao new allProducts;
	selected: currentProduct;        callback: [ :value | currentProduct := value ]; 	onChange: (html jQuery ajax script: [ :s | 
		s << "render updates here"]; serialize: (html jQuery id: selectId))

hmm. I tried your suggestion and it's almost working, but I don't see how to get the current selection value back.  If I replace the [do your stuff here] block with one that accepts an argument, like [:val | doSomethingWIth: val] I get an exception stating that the block wants an argument, but it's not being called with one. 


I tried to use html select callback: to get the selected value (this seems to be what the example on the Jquery/seaside web pages show), but it never gets invoked:


	html select 
			list: Dao new allProducts;			selected: currentProduct;            		callback: [ :value | currentProduct := value ];

 			onChange: (html jQuery ajax callback: [ 					productEntryAction value: currentProduct]).

Any other suggestions would be appreciated. Thanks again.
