Installation & Setup

Getting Ready

To get started, you will need to download the iosslider script. The download package contains the iosslider script, the jQuery library, demos and benchmarks.

Include the Necessary JavaScript Files

The jQuery library and iosslider Plugin scripts must be included in the HTML header of the web page. The jQuery library must be included first for the iosslider plugin to function.

<!-- jQuery library -->
<script type = 'text/javascript' src = 'jquery-1.4.min.js'></script>

<!-- iosslider plugin -->
<script type = 'text/javascript' src = 'jquery.iosslider.js'></script>

Add the HTML

Add the iosslider HTML code within the body of the web page. The HTML can contain as little as one slide element.

<div class = 'iosslider'>

    <!-- slider -->
    <div class = 'slider'>
    
        <!-- slides -->
        <div class = 'slide'>...</div>
        <div class = 'slide'>...</div>
        <div class = 'slide'>...</div>
    
    </div>

</div>

Add the CSS

Place the CSS in your stylesheet. The required CSS attributes are included to guarantee optimal performance. Feel free to apply as many other CSS attributes as you want. To see some real-world examples of this, check the demos folder of the iosslider download package.

/* slider container */
.iosSlider {
    /* required */
    position: relative;
    top: 0;
    left: 0;
    overflow: hidden;
    
    width: px;
    height: px;
}

/* slider */
.iosSlider .slider {
    /* required */
    width: 100%;
    height: 100%;
}

/* slide */
.iosSlider .slider .slide {
    /* required */
    float: left;

    width: px;
    height: px;
}

Add the JavaScript

Add the code below to your JavaScript file. The following code uses the jQuery selector to initialize the iosslider jQuery plugin. If you are unfamiliar with jQuery, here is a tutorial to get you started.

$(document).ready(function() {

    /* basic - default settings */
    $('.iosSlider').iosSlider();
    
    /* some custom settings */
    $('.iosSlider').iosSlider({
        snapToChildren: true,
        scrollbar: true,
        scrollbarHide: false,
        desktopClickDrag: true,
        scrollbarLocation: 'bottom',
        scrollbarHeight: '6px',
        scrollbarBackground: 'url(_img/some-img.png) repeat 0 0',
        scrollbarBorder: '1px solid #000',
        scrollbarMargin: '0 30px 16px 30px',
        scrollbarOpacity: '0.75',
        onSlideChange: changeSlideIdentifier
    });

});
