AngularJS provides a powerful animation module that allows developers to easily add animations and transitions to their web applications. This module is called ngAnimate and it is built on top of the standard CSS3 animations and transitions.
To get started with AngularJS animations, you need to include the ngAnimate module in your application. You can do this by adding the following script tag to your HTML file:
html
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.7.9/angular-animate.js"></script>
Once you have included the ngAnimate module, you can start using animations in your AngularJS application. The ngAnimate module provides several directives that you can use to animate different elements of your application.
One of the most commonly used directives is ng-show/ng-hide. This directive allows you to animate the showing and hiding of elements. For example, you can use the following code to animate the showing and hiding of a div element:
html
<div ng-show="showDiv" class="fade"></div>
In this example, the div element will be animated with a fade effect when the showDiv variable is true.
You can also use ngAnimate to animate the addition and removal of elements from a list. The ngRepeat directive provides a special class called ng-enter that you can use to animate the addition of new items to a list. Similarly, the ngLeave class can be used to animate the removal of items from a list.
html
<ul>
<li ng-repeat="item in items" class="fade" ng-enter="fadeIn" ng-leave="fadeOut">{{ item }}</li>
</ul>
In this example, the fade class is used to apply a fade effect to the list items. The ng-enter and ng-leave directives specify the animation to be used when items are added or removed from the list.
AngularJS also provides support for custom animations. You can define your own animations using CSS3 transitions and keyframes, and then use the ngAnimate module to apply these animations to your elements.
To define a custom animation, you need to use the $animate service provided by the ngAnimate module. This service allows you to add and remove CSS classes to elements, which can be used to trigger animations.
javascript
app.controller(‘MyController’, function($scope, $animate) {
$scope.animateElement = function() {
$animate.addClass(element, ‘fade’);
};
});
In this example, the animateElement function adds the fade class to the specified element, triggering the animation.
Overall, AngularJS provides a powerful and flexible animation module that allows you to easily add animations and transitions to your web applications. Whether you want to animate the showing and hiding of elements, the addition and removal of items from a list, or create custom animations, AngularJS has you covered.
