ng-animate not working in 1.3

Question

I am getting the class ng-animate applied to the directive but I'm not getting:

ng-hide-remove.ng-hide-remove-active or .ng-hide-remove.ng-hide-remove-active

I have angular and angular-animate 1.3 loaded. and am including ngAnimate in app.js

<div class="message animate-show {{message.type}}" ng-show="message">
    {{message.text}}
</div>

The transitions are not happening:

.message.animate-show {
    line-height:20px;
    opacity:1;
    padding:10px;

    &.ng-hide-add.ng-hide-add-active,
    &.ng-hide-remove.ng-hide-remove-active {
        -webkit-transition:all linear 0.5s;
        transition:all linear 0.5s;
    }

    &.ng-hide {
        line-height:0;
        opacity:0;
        padding:0 10px;
    }
}

ng-attribute was deprecated in version 1.2. It is no longer available. – Ullage

Turns out my default .message {} css was messing it up. – Haiti

Could you elaborate / add this as an answer? – Hinduism

Answer 1

For a simple animation like fading in/out, you need the following CSS classes:

.my-animation {
    -webkit-transition: 0.5s linear all;
    transition: 0.5s linear all;
    opacity: 1;
}

.my-animation.ng-hide {
    opacity: 0;
}

UPDATE:

If you have other transistion on the element that you don't want to get affected, use the following CSS definitions to only apply the transistions on the fading in/out:

.my-animation {
    opacity: 1;
}

.my-animation.ng-hide {
    opacity: 0;
}

.my-animation.ng-hide-add,
.my-animation.ng-hide-remove {
    -webkit-transition: 0.5s linear all;
    transition: 0.5s linear all;
}

The demo is build with angular-1.2, the question is regarding angular-1.3. Do you have a working example for angular-1.3? – Hinduism

@JeffreyHammansson: I updated the demo. Nothing in the code has to change. I just updated the angular version to 1.3.0-rc.2 and it still works the same. Don't forget to upvote the answer if you find t useful :) – Cassareep

Answer 2

ExpertSystem's answer above is correct. However, if you still cannot get animation to work in Angular then you need to ensure that the ngAnimate module is added to your app:

The ngAnimate module provides support for CSS-based animations (keyframes and transitions) as well as JavaScript-based animations via callback hooks.

See Source: https://docs.angularjs.org/api/ngAnimate

This can be done in your code that defines your AngularJS app as follows:

var app = angular.module('myApp', ['ngAnimate']);
