KineticJS: listening on .on ()

With KineticJS, is it possible to associate a function only once? As with jQuery equivalent ...

eg. in jQuery

// bad
$('.wrap a').on('click', myHandler);
// good
$('.wrap').on('click', 'a', myHandler);

I would like to do this with KineticJS, as there will be many objects there.

This is Eric from KineticJS. Currently, you can use container.get () to get an array of nodes similar to jQuery, for example:

layer.get('Rect'); // returns all rectangles inside of layer
layer.get('.foo'); // returns all nodes with name foo inside layer
stage.get('#bar'); // returns node with id 'bar'

but you still cannot bind events to all nodes using a selector, for example:

layer.get ('Rect'). on ('click', ...);

I will add this to my task list, so it should probably be released in a couple of weeks :)

Hooray!
