Storing Smalltalk References in JS

Administrator

I'm using jstree to represent Smalltalk objects logically organized as a tree. When the user selects a node, I want to send a message to the Smalltalk object corresponding to it. However, how do I store a reference to the Smalltalk object in the jstree? I'm using html as data - is there an object id/pointer that I could write as an attribute of the tag? Or is there a better way?

Thanks.

Cheers,
Sean

Smalltalk aside, when putting JS objects into DOM, jQuery's data() comes first to mind. Or do you need something else?

Looks perfect!

'#div_id' asJQuery data: 'obj' put: myInstance
('#div_id' asJQuery data: 'obj') smalltalkMessage
works like a charm - thanks :)

Drats - jsTree clears the data during its magical initialization :( I asked how others are handling this on SO... https://stackoverflow.com/questions/24842453/jstree-bind-to-domain-objects

It's a great question - keen to hear the response so we can learn how to do things like this.

jQuery data seems to be the way to go. The only twist with jsTree is that the data gets moved for optimization reasons, so it must be accessed in the callback like so:
$('#jsTree_div').on('select_node.jstree', function (e, data) {
data.node.data.some_key //... (instead of $('#node_id').data('some_key'))
});

I answered and updated the SO question http://stackoverflow.com/questions/24842453/jstree-bind-to-domain-objects
