DEPRECATED: ngAnimatedScroll

A promise based angular.js service to facilitate animated scrolling

Deprecation notice

Due to the end of life of Angular.js, this module is deprecated and no longer maintained.

Features

• Exposes a service that scrolls an arbitrary element to another element's location.
• Promise enabled: The service returns a promise and resolves upon completion of the scroll operation.
• Selector enabled: Use CSS selectors to specify to which element to scroll.
• Leverages window.getAnimationFrame() for a smooth and efficient scroll animation
• Clean: No classes, no jQuery, no CSS, just plain Angular.js

Installation

1. Install the ngAnimatedScroll package

via NPM:

npm install ng-animated-scroll --save

or Bower:

bower install ng-animated-scroll --save

2. Include the library into your application:

if installed via NPM include from node_modules:

<script src="/node_modules/ng-animated-scroll/dist/ngAnimatedScroll.service.min.js"></script>

if installed via Bower include from bower_components:

<script src="/bower_components/ng-animated-scroll/dist/ngAnimatedScroll.service.min.js"></script>

Usage

1. Add a dependency to AnimatedScroll to your app

   angular.module('myApp', ['AnimatedScroll']);

2. Inject the animatedScroll service into your directive, factory, controller, etc. and call it's scroll() method.

   angular.module('myController', ['animatedScroll', function(animatedScroll) {
     animatedScroll.scroll(elementToScrollTo);
   }]);

Example: Simple scroll operation

angular.module('myController', ['animatedScroll', function(animatedScroll) {
  var elementIWantToScrollTo = document.getElementById('anElementIWantToScrollTo');
  animatedScroll.scroll(elementIWantToScrollTo);
}]);

Example: Using CSS selectors

angular.module('myController', ['animatedScroll', function(animatedScroll) {
  animatedScroll.scroll('#someElement');
}]);

Example: Leveraging the promise

angular.module('myController', ['animatedScroll', function(animatedScroll) {
  var elementIWantToScrollTo = document.getElementById('anElementIWantToScrollTo');
  animatedScroll.scroll(elementIWantToScrollTo)
    .then(function(element) {
      // do something after the element was scrolled into view
      // element = elementIWantToScrollTo
    });
}]);

Example: Scrolling within an Element

angular.module('myController', ['animatedScroll', function(animatedScroll) {
  var listItemIWantToScrollTo = document.getElementById('listItemIWantToScrollTo');
  var list = document.getElementById('aList');
  animatedScroll.scroll(elementIWantToScrollTo, {
    scrollElement: list
  }).then(function(element) {
    // do something after the the list item was scrolled into view
    // element = listItemIWantToScrollTo
  });
}]);
