disable nganimate for some elements

问题:

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.

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>

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);

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);
    };
});

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.

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;
  }
}

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!

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. */

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.
