Step By Step To Create Content Slider using jFlow, A Minimalist jQuery Plugin
There are a lot of free scripts to create a content slider. One of the example is SmoothGallery by JonDesign. But, if you are using jQuery and don’t want to install another JavaScript library, then you may need to consider jQuery slider plugin.
Today, i am going to provide a tutorial on using jFlow, a minimalist jQuery plugin to create a content slider. Readers are required to have basic XHTML/CSS and JavaScript skills. I will provide a download link after this tutorial. This is the first tutorial post on WebDesignBooth, and i will write more tutorials in future.
So, let’s start to create our content-slider now. Download both jQuery and jFlow before you proceed.
1. Create a style.css file, and insert the following code into the file:
#jFlowSlide{ background:#DBF3FD; font-family: Georgia; }
#myController { font-family: Georgia; padding:2px 0; width:610px; background:#3AB7FF; }
#myController span.jFlowSelected { background:#43A0D5;margin-right:0px; }
.slide-wrapper { padding: 5px; }
.slide-thumbnail { width:300px; float:left; }
.slide-thumbnail img {max-width:300px; }
.slide-details { width:290px; float:right; margin-left:10px;}
.slide-details h2 { font-size:1.5em; font-style: italic; font-weight:normal; line-height: 1; margin:0; }
.slide-details .description { margin-top:10px; }
.jFlowControl, .jFlowPrev, .jFlowNext { color:#FFF; cursor:pointer; padding-left:5px; padding-right:5px; padding-top:2px; padding-bottom:2px; }
.jFlowControl:hover, .jFlowPrev:hover, .jFlowNext:hover { background: #43A0D5; }2. Open your main document and include the style.css, jQuery, and jFlow in the <head> tag.
<link rel="stylesheet" href="style.css" type="text/css" media="screen" />
<script language="javascript" type="text/javascript" src="jquery-1.3.2.min.js"></script>
<script language="javascript" type="text/javascript" src="jquery.flow.1.2.js"></script>
3. Then add this simple JavaScript code to define the settings for jFlow
<script type="text/javascript">
$(document).ready(function(){
$("#myController").jFlow({
slides: "#slides", // the div where all your sliding divs are nested in
controller: ".jFlowControl", // must be class, use . sign
slideWrapper : "#jFlowSlide", // must be id, use # sign
selectedWrapper: "jFlowSelected", // just pure text, no sign
width: "610px", // this is the width for the content-slider
height: "235px", // this is the height for the content-slider
duration: 400, // time in miliseconds to transition one slide
prev: ".jFlowPrev", // must be class, use . sign
next: ".jFlowNext" // must be class, use . sign
});
});
</script>
Think #slides as a container, which contain all slides, while .jFlowControl is the controller which let us go to the individual slide. As you can see from the style.css, we have 300px .slide-thumbnail to display our image, 290px .slide-details to display our title and description. Besides these, we have 10px margin-left for the .slide-description and 5px padding for the .slide-wrapper. So totally we need 610px width. For the “height” setting, you need to estimate the maximum height for your content. Here, i will use 235px as an example.
4. Now is the turn to create the individual slide. The slide is contained in the #slides div. Here, i will conly show one slide. You may refer the source code for more info.
<div class="slide-wrapper">
<div class="slide-thumbnail">
<!-- image here -->
</div>
<div class="slide-details">
<h2><!-- title here --></h2>
<div class="description">
<!-- description here. -->
</div>
</div>
<div class="clear"></div>
</div>
5. We will wrap everything in a .slide-wrapper class, and float our thumbnail to the left while our content to the right. Don’t forget to clear the floats also. Replace image, title, and description with your own content.
After that, we may add controls to the slides, which are resides in a #myController div.
<span class="jFlowPrev">Prev</span>
<span class="jFlowControl">1</span>
<span class="jFlowNext">Next</span>
The .jFlowPrev and .jFlowNext are necessary controls to go to previous and next slides, while .jFlowControl is a “button” to jump to any particular slide. The number of .jFlowControl span is depends on the number of slides you have.
