Angular JS Tutorial #24: Implementing Angular Animation

Posted by


In this tutorial, we will be exploring how to use Angular Animation in your AngularJS applications. Angular Animation provides a powerful way to create smooth and engaging animations for various user interactions, such as transitions, fades, and scrolling effects.

Angular Animation is a built-in module in AngularJS that allows you to create animations using CSS and JavaScript. It provides a set of directives and components that make it easy to add animations to your Angular applications.

To get started with Angular Animation, you first need to include the ngAnimate module in your AngularJS application. You can do this by adding the following script tag to your HTML file:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.7.8/angular-animate.js"></script>

Next, you need to inject the ngAnimate module as a dependency in your AngularJS application:

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

Now that you have set up ngAnimate, let’s look at how you can use Angular Animation to create animations in your AngularJS application.

  1. Define animations in CSS:

The first step in creating animations with Angular Animation is to define the animations in your CSS file. You can use CSS keyframes to define animations, such as fades, transitions, and other effects. For example, you can create a simple fade-in animation like this:

.fade-in {
  animation: fadeIn 1s;
}

@keyframes fadeIn {
  from {
    opacity: 0;
  }
  to {
    opacity: 1;
  }
}
  1. Use Angular directives to apply animations:

Next, you can use Angular directives to apply the animations to elements in your AngularJS application. For example, you can apply the fade-in animation to an element using the ng-class directive like this:

<div ng-class="{ 'fade-in': showElement }">Hello, World!</div>

In the above example, the ‘fade-in’ class will be added to the

element when the value of showElement is true, resulting in a fade-in animation effect.

  1. Trigger animations with Angular events:

You can also trigger animations based on Angular events, such as ng-click, ng-mouseenter, ng-mouseleave, etc. For example, you can create a button that triggers a slide-up animation when clicked like this:

<button ng-click="slideUp = !slideUp">Toggle Slide Up</button>
<div ng-class="{ 'slide-up': slideUp }">Lorem ipsum dolor sit amet</div>

In the above example, clicking the button will toggle the value of slideUp, which will trigger the slide-up animation on the

element.

  1. Using ng-show/ng-hide with animations:

You can also use the ng-show and ng-hide directives to animate elements when they are shown or hidden. For example, you can create a simple fade-in/fade-out animation when a element is shown or hidden like this:

<button ng-click="showElement = !showElement">Toggle Element</button>
<div ng-show="showElement" class="fade-in">Hello, World!</div>

In this example, the ‘fade-in’ animation will be applied to the

element when it is shown using the ng-show directive.

That’s it! You have now learned how to use Angular Animation to create smooth and engaging animations in your AngularJS applications. Experiment with different animations and effects to create stunning user experiences in your web applications. Happy coding!
