Behavior-registration for UJS with jQuery

behaviors.js

// An Unobtrusive Javascript (UJS) driver based on explicit behavior definitions. Just
// put a "data-behaviors" attribute on your view elements, and then assign callbacks
// for those named behaviors via Behaviors.add.

$.behaviors = {
  add: function(trigger, behavior, handler) {
    $('[data-behaviors~=' + behavior + ']').each(function() {
      $(this).bind(trigger, handler);
    });
  }
};
