jmpress.js

A jQuery port of impress.js based on the power of CSS3 transforms and transitions in modern browsers and inspired by the idea behind prezi.com.

BROWSER SUPPORT

jmpress.js is made for the latest browsers. Old browsers get old styles. Here is the support list for the latest version of each browser:

Chrome/Chromium: YES
Safari: YES
Firefox: ALMOST
IE: NO
Opera: PARTIAL
iOS: PARTIAL
Android: ?

USAGE

Take a look at the index.html and css/style.css for an example. The only required files are jQuery and js/jmpress.js to use.

Create a root element

<div id="jmpress"></div>

Fill it up with steps

<div id="jmpress">
    <div class="step">Slide 1</div>
    <div class="step">Slide 2</div>
</div>

Configure each step properties

<div id="jmpress">
    <div class="step" data-x="3500" data-y="-850" data-rotate="270" data-scale="6">Slide 1</div>
    <div class="step" data-x="2825" data-y="2325" data-z="-3000" data-rotate="300" data-scale="1">Slide 2</div>
</div>

Tell jQuery to run it

<script type="text/javascript">
$(function() {
    $('#jmpress').jmpress();
});
</script>

Configure jmpress

Don't want to use .step as a selector? Okay:

$('#jmpress').jmpress({
    stepSelector: 'li'
});

Customize the hash id of each slide

The id of the step will appear as the URI hash to recall the slide later. If you don't give your steps ids then the id step-N will be used.

<div id="name-of-slide" class="step" data-x="3500" data-y="-850" data-rotate="270" data-scale="6">Slide 1</div>

Load slides dynamically

You can load a slide dynamically by setting the data-src or href attribute on the slide. The slide will only be loaded when an adjacent slide or the slide itself is selected.

<div class="step" data-src="slides/slide-1.html" data-x="500" data-y="300">Loading...</div>

API

Steps

Each step element can have the following data properties set:

data-x: X Position
data-y: Y Position
data-z: Z Position
data-scale: Scale of element
data-rotation: Degree of rotation
data-rotation-x: Degree of rotation on x-axis
data-rotation-y: Degree of rotation on y-axis
data-rotation-z: Degree of rotation on z-axis
data-src: Load content of slide dynamically

jQuery.jmpress()

$(selector).jmpress({
    // jQuery selector to select each step
    stepSelector: '.step'

    // Class name to give the canvas
    ,canvasClass: 'canvas'

    // Class name to trigger if jmpress is not supported
    ,notSupportedClass: 'not-supported'

    // Customize the animations (or CSS) used
    ,animation: {
        ,transitionDuration: '5s'
        ,transitionTimingFunction: 'linear'
    }
});

METHODS

// Next slide
$(selector).jmpress('next');

// Previous slide
$(selector).jmpress('prev');

// Goto a slide
$(selector).jmpress('select', '#slide-id');
$(selector).jmpress('select', $(selector));

// Manipulate the canvas
$(selector).jmpress('canvas', {
    transform: 'rotate(7deg)'
});

// Manipulate an element
$(selector).jmpress('css', $('#step-1'), {
    transform: 'scale(0.5)'
});

// Set a beforeChange callback
$(selector).jmpress('beforeChange', function( slide ) {
    // Called on the start of each slide change
});
