Readme

This is a set of customized scrollbars for AngularJS that allows you to apply consistent styles and behavior across different browsers (including Firefox) that's built around Malihu's jQuery Custom Scrollbar by Manos Malihutsakis. It provides an AngularJS directive with universal configuration or individual scrollbar configuration.

Usage

1. Add ng-scrollbars and its dependencies to your main file (index.html) This can be downloaded by

• Using bower and running bower install ng-scrollbars
• Or downloading the production version or the development version.
• Or downloading the demo zip file

In your web page:

<link rel="stylesheet" href="bower_components/malihu-custom-scrollbar-plugin/jquery.mCustomScrollbar.min.css" type="text/css"/>
<script src="bower_components/jquery/dist/jquery.min.js"></script>
<script src="bower_components/angular/angular.min.js"></script>
<script src="bower_components/malihu-custom-scrollbar-plugin/jquery.mCustomScrollbar.concat.min.js"></script>
<script src="bower_components/ng-scrollbars/dist/scrollbars.min.js"></script>

2. Set ngScrollbars as a dependency in your module

var app = angular.module('app', ['ngScrollbars'])

3. Add ng-scrollbar directive to any elements:

<div ng-scrollbars ng-scrollbars-config="config"> .... </div>

4. Specify the configuration as an object visible within the directive's scope:

   4a. For example, the 'config' object referenced in step 3 could be configured like the following:

   $scope.config = {
   	autoHideScrollbar: false,
   	theme: 'light',
   	advanced:{
   		updateOnContentResize: true
   	},
   		setHeight: 200,
   		scrollInertia: 0
   	}
   }

   4b. Some system-wide settings, such as enabling the buttons, can also be set by configuring the ScrollBarsProvider that's included in the ngScrollbars module as referenced in step 2:

   var app = angular.module('app', ['ngScrollbars']);
   app.config(function (ScrollBarsProvider) {
   	ScrollBarsProvider.defaults = {
   		scrollButtons: {
   		    scrollAmount: 'auto', // scroll amount when button pressed
   			enable: true // enable scrolling buttons by default
   		},
   		axis: 'yx' // enable 2 axis scrollbars by default
   	};
   });

   4c. System-wide defaults can also be specified. However, these settings are overridden by any scope level configuration as shown in 4a. For example:

   var app = angular.module('app', ['ngScrollbars']);
   app.config(function (ScrollBarsProvider) {
   	// the following settings are defined for all scrollbars unless the
   	// scrollbar has local scope configuration
   	ScrollBarsProvider.defaults = {
   		scrollButtons: {
   			scrollAmount: 'auto', // scroll amount when button pressed
   			enable: true // enable scrolling buttons by default
   		},
   		scrollInertia: 400, // adjust however you want
   		axis: 'yx', // enable 2 axis scrollbars by default,
   		theme: 'dark',
   		autoHideScrollbar: true
   	};
   });

All configuration options available to Malihu's scrollbar can be provided through the above configuration. See Malihu's page for more details

Updating Scrollbars

As of 0.0.6, scrollbars can be dynamically updated:

For example:

app.controller('mainCtrl', function ($scope, $timeout) {
    $timeout(function() {
        $scope.updateScrollbar('scrollTo', 10);
    });
});

<div class="container" ng-scrollbars ng-scrollbars-update=updateScrollbar ng-controller="mainCtrl">
	<h1>Title</h1>
	<p>A bunch of content</p>
</div>

See this demo

Other options may include:

• $scope.updateScrollbar('update', ...). Manually updates the scrollbar
• $scope.updateScrollbar('disable'). Temporarily disables scrollbar
• $scope.updateScrollbar('stop'). Stops any running scrolling animations
• $scope.updateScrollbar('destroy'). Completely removes the scrollbar and returns element to original state

See Malihu's documentation for more information on the available callbacks.

Common Gotchas

If the width for some reason keeps shrinking then make sure you specify the width of the CSS for all children elements where ng-scrollbars is applied.

Here's an example ng-scrollbars use case:

<div class="container" ng-scrollbars>
	<h1>Title</h1>
	<p>A bunch of content</p>
</div>

The CSS may need to structured like the following:

.container {
	width: 250px;
}

.container p, .container h1 {
	width: 210px;
}

This is because Malihu looks at the width of the child elements and adjusts, so the child elements may shrink to 0 width if nothing is specified. Also note the container width is a little wider than its contents width because of the extra scrollbar width.

History

I needed an AngularJS scrollbar that worked well with a dark theme and was consistently styled across different browsers. I found several Angular scrollbars listed below but in general the styling didn't fit or they were lacking features.

Ultimately I found a Stackoverflow post by JMaylin that inspired me to continue the integration effort he/she started.

Other options

In my search for angularjs scrollbars, I also came across a few others:

• Ng-scrollbar
• Angular-perfect-scrollbar
• ngTinyScrollbar
