backbone-touch-click.js

var down = "touchup" in window ? "touchup" : "click";

var abstractView = Backbone.View.extend({
    // we don't want both click and touch handlers
    // delegated on touch-enabled devices
    events: function () {
        "click .toggler" : "foo", 
        "touchup .toggler" : "bar"
    },
    initialize: function () {
      // we can do this instead
      this.events = this.events || {};
      this.events[down + ' .toggler'] = "foo";
      // … list more events here
      this.delegateEvents();
    }
});

// This does solve the problem but this doesn't look good
//
// We could do something like jQuery special event, but Zepto,
// that is used on mobile devices doesn't support special events
//
// So seamless "down .toggler" : "foo", that would work by registering
// "special" jQuery event will not work with Zepto
