FlexSlider Directive for AngularJS

Provides a flex-slider directive to include and initialize a FlexSlider slideshow in an AngularJS application.

Intallation

To install using npm:

npm install angular-flexslider-nsp

Setup

In your document header include FlexSlider's CSS:

<link rel="stylesheet" type="text/css" href="/node_modules/flexslider/flexslider.css">

Then include the scripts (order is relevant):

<script src="/node_modules/jquery/dist/jquery.min.js"></script>
<script src="/node_modules/flexslider/jquery.flexslider-min.js"></script>
<script src="/node_modules/angular/angular.min.js"></script>
<script src="/node_modules/angular-flexslider-nsp/angular-flexslider.js"></script>

In your AngularJS app, you'll need to import the angular-flexslider module:

angular.module('myModule', ['angular-flexslider']);

Usage

This module will define a single directive flex-slider that can be used either as an element or attribute.

Assuming a mySlides variable is present in the current scope, a FlexSlider instance can be declared like so:

<flex-slider slide="s in mySlides">
	<li>
		<img ng-src="{{s}}">
	</li>
</flex-slider>

The slide argument works similarly to ngRepeat in which you can specify a tracking expression.

The <li> element should be defined and it can be used to specify data-thumbs attribute for FlexSlider thumbs or, for example, ng-switch to select the content markup.

Warning to UI Bootstrap users: You must use the flex-slide argument instead of slide to avoid name conflict with the carousel. This is:

<flex-slider flex-slide="s in mySlides">
	<li>
		<img ng-src="{{s}}">
	</li>
</flex-slider>

Properties

FlexSlider initialization properties can be specified as attributes of flex-slider directive using dash separated attributes instead of cammel case.

For example, the property controlNav can be specified via the attribute control-nav.

The FlexSlider callback API can also be used by specifying attributes with the appropriate API name containing AngularJS expressions.

Besides FlexSlider properties, one can specify a slider-id attribute to set an id to the actual slider. If not specified and an id attribute is specified to the flex-slider element, the actual slider will have an id of <id>-slider.
