backbone.jsHow do I add an onclick event to a Backbone.js element?

The easiest way to add an onclick event to a Backbone.js element is to use the view's events hash. This hash is used to bind DOM events to methods on the view.

For example, if you have a view called ButtonView, you could set up the onclick event like so:

var ButtonView = Backbone.View.extend({
  events: {
    'click .my-button': 'onButtonClick'
  },
  onButtonClick: function(e) {
    // Do something
  }
});

In the above example, the events hash binds the onButtonClick method to the click event of any element with the class my-button.

The onButtonClick method will be called when the click event is triggered, and the click event's data will be passed as the e argument.
