Question

I have a joint.js element in a DAG, and would like to be able to trigger an event by clicking on it.

I could use $(selector).click(...) to do it, but I was

Answer 1

The JointJS shapes are models, so you're right that click handlers won't work on them. The JointJS paper triggers events that might be useful to you:

paper.on('cell:pointerdown', 
    function(cellView, evt, x, y) { 
        alert('cell view ' + cellView.model.id + ' was clicked'); 
    }
);

other events are: cell:pointerup, cell:pointerdblclick, cell:pointermove.

The complete list can be found here: http://jointjs.com/api#joint.dia.Paper:events.

EDIT:

Starting from JointJS v0.9, there is also a cell:pointerclick event.

You can also use Backbone itself to attach specific events to specific models. JointJS is just Backbone under the hood.

const newElement = new jointjs.shapes.devs.Model({....});
graph.addCell(newElement);

newElement
  .findView(paper)
  .$el.find('.Settings') // this is nested in the model / cell
  .click(() => {
    // do something
  });
