Javascript Question

Angular 1.5.0. Root Template is duplicated when reloading the page with UI GRID via ocLazyLoad. $$animateJs is undefined

I'm using:


  • Angular, angular-animate both are v. 1.5.0

  • Angular UI Grid v. 3.1.1

  • ocLazyLoad v. 1.0.9

  • Angular ui router v. 0.2.18



The Error is:


TypeError: $$animateJs is not a function
at d (angular-animate.js:2141)
at angular-animate.js:2131
at h (angular-animate.js:3174)
at Array.d.push.fn (angular-animate.js:3020)
at c (angular-animate.js:423)
at b (angular-animate.js:393)
at angular-animate.js:3042
at m.$digest (angular.js:16714)
at m.$apply (angular.js:16928)
at g (angular.js:11266)



This error occurs when I refresh the page which contains UI Grid
and

UI Grid module is loaded by ocLazyLoad.




If I place UI Grid script in <'body'> all work fine. Just when I use ocLazyLoad.


Other pages work fine. When I change state also works fine. Only when refreshing.

Not matter if it is F5 or Ctrl + F5


The most strange thing I've seen is that my root template is duplicated


enter image description here

UPDATE:



I've uploaded project sample to GITHUB



So the initial state is $state without GRID


If you switch between the states everything works fine.
BUT
If you reload a page on grid state or change initial state to state with grid entire template is duplicated.

The reason of this is angular-animate. If it is turned off everything is OK.


Thanks!

It would be nice to see the network tab of your chrome dev-tools. I suspect the order in which things are loaded to be 'wrong'.

Looking through some code of ui.grid, I actually found a part that checks for ngAnimate in a (possibly too) dynamic way (in this case):

// Disable ngAnimate animations on an element
disableAnimations: function (element) {
  var $animate;
  try {
    $animate = $injector.get('$animate');
    // See: http://brianhann.com/angular-1-4-breaking-changes-to-be-aware-of/#animate
    if (angular.version.major > 1 || (angular.version.major === 1 && angular.version.minor >= 4)) {
      $animate.enabled(element, false);
    } else {
      $animate.enabled(false, element);
    }
  }
  catch (e) {}
},

enableAnimations: function (element) {
  var $animate;
  try {
    $animate = $injector.get('$animate');
    // See: http://brianhann.com/angular-1-4-breaking-changes-to-be-aware-of/#animate
    if (angular.version.major > 1 || (angular.version.major === 1 && angular.version.minor >= 4)) {
      $animate.enabled(element, true);
    } else {
      $animate.enabled(true, element);
    }
    return $animate;
  }
  catch (e) {}
},

Now, I am not sure why ui.grid actually fiddles around with animations, but I could imagine some problems concerning the order in which things are loaded.

edit: It's a load-order bug. When loading ngAnimate with ocLazyLoad and ensuring it's loaded before ui.grid, it works.

Presuming you've added ngAnimate as a module to LazyLoad, your state's resolve has to be changed to:

resolve: load(['ngAnimate', 'ui.grid', 'grid/GridController.js'])

Of course this isn't ideal, as loading time is increased upon entering the grid-state, but I'm too tired to look further into it right now. At least now you know that it definitely has to do with the loading order.

edit2: Another solution (in case you always include ngAnimate):

In your router.config, try the following for the load function

function load(srcs, callback) {
    return {
        deps: ['$$animateJS', '$ocLazyLoad', '$q',
                function ($$animateJS, $ocLazyLoad, $q) {
                    ...
        }]
    };
}
