Let's get on with it!

##Installation

###Step 1: Link required files

First and most important, the jQuery library needs to be included (no need to download - link directly from Google). Next, download the package from this site and link the bxSlider CSS file (for the theme) and the bxSlider Javascript file.

<!-- jQuery library (served from Google) -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<!-- bxSlider Javascript file -->
<script src="/js/jquery.bxslider.min.js"></script>
<!-- bxSlider CSS file -->
<link href="/lib/jquery.bxslider.css" rel="stylesheet" />

###Step 2: Create HTML markup

Create a <ul class="bxslider"> element, with a <li> for each slide. Slides can contain images, video, or any other HTML content!

<ul class="bxslider">
  <li><img src="/images/pic1.jpg" /></li>
  <li><img src="/images/pic2.jpg" /></li>
  <li><img src="/images/pic3.jpg" /></li>
  <li><img src="/images/pic4.jpg" /></li>
</ul>

###Step 3: Call the bxSlider

Call .bxSlider() on <ul class="bxslider">. Note that the call must be made inside of a $(document).ready() call, or the plugin will not work!

$(document).ready(function(){
  $('.bxslider').bxSlider();
});

example:
slider = $('.bxslider').bxSlider();
slider.startAuto();

stopAuto Stops the auto show. Provide an argument false to prevent the auto controls from being updated.

example:
slider = $('.bxslider').bxSlider();

Install Grunt and Bower

Unfamiliar with npm? Don't have node installed? Download and install node.js before proceeding.

From the command line:

  1. Install grunt-cli and bower globally with npm install -g grunt-cli bower.

  3. Run bower install, which installs front-end packages defined in bower.json.

When completed, you'll be able to run the various Grunt commands provided from the command line.

Available Grunt commands

  • grunt — Clean, Compile LESS to CSS, concatenate and validate JS, build documentation.
  • grunt dist — Clean, Compile LESS to CSS, concatenate and validate JS for plugin only.
  • grunt docs — Clean, build documentation only.
  • grunt watch — loads LiveReload, connects, and watches all assets.
  • grunt zip — Creates a zip of /dist and places it in /download.

  • Fix: Reverse #714, fixes #722.
  • Fix: Repo Tag #729
  • Fix: #720 pagerCustom issues

4.2.0 Introduces a streamlined build process using gulp. Along with this new build process the projects folder structure has been changed. You will find a dist folder with all assets ready to use, including both minified and unminified versions of the javascript. These assets should be ready to go. In src you will find the uncompiled assets, including a new less version of the css for bxslider. This is an important step for bxslider. It will help speed development up and keep work clean. It also paves the way for a big revamp we have planned in the future.

Unfamiliar with npm? Don't have node installed? Download and install node.js before proceeding.

From the command line:

  1. Install gulp globally with npm install -g gulp
  2. Navigate to the project directory, then run npm install

You now have all the necessary dependencies to run the build process.

Available gulp commands

  • gulp — Compile and optimize all files to dist
  • gulp styles — Compile css assets only to dist
  • gulp scripts — Compile js assets only to dist
  • gulp images - Run lossless compression on all the images and copy to dist
  • gulp jshint — Checks JS and JSON code for errors based on our .jshintrc settings

  • Added bower.json configuration file. Manage bxSlider as a dependency using bower.

Version 4.1.1

  • Removed imagesLoaded library and added iframe preloading support
  • Added responsive option - setting to false will prevent $(window).resize binding

Version 4.1

  • Carousel mode (minSlides / maxSlides) was re-written to be more intuitive.
  • SlideWidth now acts as it should (slides respect the width value).
  • SlideWidth now properly parsed: accepts string ("600px") or integer (600).
  • Slider now only needs to load visible slides (by default) in order to initialize which results in much faster loading. A "preloadImages" setting allows for configuration.

Long live Zep.
