get model triggering events in collection

Question

I have a collection of models in Backbone. One model is triggering a custom event, that I can catch, listening to the collection. What is the best way to find out, which model triggered the event?

Answer 1

You can add the model ID with your custom event like this:

yourModel.trigger('customEvent', yourModel.get('id'))

and on the callback that catch the custom event you'll get the id as a parameter:

yourCallback: function(id) {
    ...
}
