A ultra simple view handler

view.js

if (Meteor.isClient) {

  // Basic animation handling
  var defer = function(current, last, scroll) {
    // Set the hide class and then remove the show
    $('#'+last).addClass('hide').removeClass('show');
    // Remove the hide - this will make the transition fast
    $('#'+current).removeClass('hide');

    Meteor.setTimeout(function() {
      $('#'+current).addClass('show');
      if (scroll) scroll.refresh();
    }, 100);
  };

  // Create a view with a name
  View = function(name) {
    var self = this;

    self._current = name;
    self._prev = name;
    self._time = new Date();

    self._deps = new Tracker.Dependency();
  };
  
  View.prototype.set = function(name, toggle) {
    var self = this;

    if (new Date() - self._time < 100) return;
    self._time = new Date();

    if (name == self._current) {
      if (toggle) {
        // Go back
        name = self._prev;
      } else {
        // We are already here
        return;
      }
    }

    defer(name, self._current, ScrollView.get(name));

    self._prev = self._current;
    self._current = name;
    self._deps.changed();
  };
  
  View.prototype.get = function() {
    var self = this;    
    self._deps.depend();
    return self._current;
  };

  View.prototype.setDefault = function(name) {
    var self = this;
    self._prev = name;    
    self._current = name;
  };

  View.prototype.refresh = function() {
    var self = this;
    // Update iscroll
    var scroll = ScrollView.get(self._current);
    if (scroll) scroll.refresh();
  };  

  contentsView = new View('main');
}

contentsView.get() - returns the name of the current view
contentsView.set('id'); - activate div with id

Logic for backbutton:

AppBackRoute = {
  'foo': 'foos',
  'foos': 'main'
};

    cordovaApi.addEventListener('backbutton', function(e) {
      var currentView = contentsView.get();

      if (currentView === 'main') {
        // If current page is main then exit the app
        cordovaApi.close();
      } else {
        // Else goto main - or last page?
        contentsView.set(AppBackRoute[currentView] || 'main'); 
      }
    });
