disable nganimate for some elements

Question

I'm using the ngAnimate module, but all my ng-if, ng-show, etc, are affected by that, I want to leverage ngAnimate for some selected elements. For performance and some bugs in elements that shows and hide very speedy.

thanks.

Answer 1

If you want to enable animations for specific elements (as opposed to disabling them for specific elements) you can use the $animateProvider to configure elements with a particular class name (or regex) to animate.

The code below will enable animations for elements that have the angular-animate class:

var myApp = angular.module("MyApp", ["ngAnimate"]);
myApp.config(function($animateProvider) {
  $animateProvider.classNameFilter(/angular-animate/);
})

Here is example markup that includes the angular-animate class to enable animations:

<div ng-init="items=[1,2,3,4,5,6,7,8,9]">
  <input placeholder="Filter with animations." ng-model="f" /> 
  <div class="my-repeat-animation angular-animate" ng-repeat="item in items | filter:f track by item" >
    {{item}}
  </div>
</div>

Plunker example borrowed and modified from this blog where only the first filter has animations (due to having the angular-animate class).

Please note that I'm using angular-animate as an example and it is completely configurable using the .classNameFilter function.

There are two ways you can disbale animations in AngularJS if you have the module ngAnimate as a dependency on your module:

1. Disable or enable the animation globally on the $animate service:

   $animate.enabled(false);
   

2. Disable the animations for a specific element - this must be the element for that angular will add the animationstate css classes (e.g. ng-enter, ...)!

   $animate.enabled(false, theElement);

As of Angular 1.4 version you should reverse the arguments:

$animate.enabled(theElement, false);

Answer 3

To disable ng-animate for certain elements, using a CSS class, which follows Angular animate paradigm, you can configure ng-animate to test the class using regex.

Config

    var myApp = angular.module("MyApp", ["ngAnimate"]);
    myApp.config(function($animateProvider) {
        $animateProvider.classNameFilter(/^(?:(?!ng-animate-disabled).)*$/);
    })

Usage

Simply add the ng-animate-disabled class to any elements you want to be ignored by ng-animate.

Just add this to your CSS. It is best if it is the last rule:

.no-animate {
   -webkit-transition: none !important;
   transition: none !important;
}

then add no-animate to the class of element you want to disable. Example:

<div class="no-animate"></div>

Answer 5

thanks, i wrote a directive which you can place on the element

CoffeeScript:

myApp.directive "disableAnimate", ($animate) ->
  (scope, element) ->
    $animate.enabled(false, element)

JavaScript:

myApp.directive("disableAnimate", function ($animate) {
    return function (scope, element) {
        $animate.enabled(false, element);
    };
});

I've found that $animate.enabled(false, $element); will work for elements that use ng-show or ng-hide but it will not work for elements that use ng-if for some reason! The solution I ended up using was to just do it all in CSS, which I learned from this thread on GitHub.

CSS

/* Use this for transitions */
.disable-animations.ng-enter,
.disable-animations.ng-leave,
.disable-animations.ng-animate {
  -webkit-transition: none !important;
  transition: none !important;
}

/* Use this for keyframe animations */
.disable-animations.ng-animate {
  -webkit-animation: none 0s;
  animation: none 0s;
}

SCSS

.disable-animations {
  // Use this for transitions
  &.ng-enter,
  &.ng-leave,
  &.ng-animate {
    -webkit-transition: none !important;
    transition: none !important;
  }
  // Use this for keyframe animations
  &.ng-animate {
    -webkit-animation: none 0s;
    animation: none 0s;
  }
}

Answer 7

I do NOT want to use ngAnimate on my ng-if's, so this would be my solution:

[ng-if] {
  .ng-enter, .ng-leave, .ng-animate {
    -webkit-transition: none !important;
    transition: none !important;
  }
}

Just posting this as another suggestion!

Answer 8

I have a list from which the first li is hidden using ng-hide="$first". Using ng-enter results in the li being shown for half a second before disappearing.

Based on Chris Barr's solution, my code now looks like this:

HTML

<ol>
    <li ng-repeat="item in items"
        ng-hide="$first"
        ng-class="{'no-animate' : $first}">
    </li>
</ol>

CSS

.no-animate.ng-enter,
.no-animate.ng-leave,
.no-animate.ng-animate {
        transition: none !important; /* disable transitions */
        animation: none 0s !important; /* disable keyframe animations */
}

li.ng-enter {
    opacity: 0;
    transition: opacity 0.3s ease-out;
}
li.ng-enter-active {
    opacity: 1;
}

/* I use Autoprefixer. If you don't, please include vendor prefixes. */

Answer 9

I know that it is a delayed reply, but here we use in MainController:

// disable all animations
$animate.enabled(false);

But the problem is that when we disable all animations, the ui-select are configured to opacity: 0.

So, its necessary to set opacity to 1 using CSS:

.ui-select-choices {
    opacity: 1 !important;
}

This will properly set opacity and the ui-select will work.
