Mobify Pikabu

A mobile-first content fly-in UI plugin.

Dependencies

• Zepto
• Mobify's fork of Velocity.js
• Plugin
• Shade
• Lockup
• Deckard
• Bouncefix

Velocity

If you are using Zepto, you need to load bower_components/mobify-velocity/velocity.js (this file comes with a jQuery shim bundled directly in it). If you are using jQuery, you need to load bower_components/velocity/jquery.velocity.js.

jQuery Support

Pikabu supports jQuery but is not actively developed for it. You should be able to use Pikabu directly with jQuery 2.0. While we don't actively support jQuery for Pikabu, we welcome any and all issues and PRs to help us make it work.

Installation

Pikabu can be installed using bower:

bower install pikabu

Usage with Require.js

We highly recommend using Require.js with Pikabu. To use Require, you have to reference Pikabu, Pikabu's effect modules, and Pikabu's dependencies inside your require config file:

{
    'paths': {
        'plugin': 'bower_components/plugin/dist/plugin.min',
        'pikabu': 'bower_components/pikabu/dist/pikabu.min',
        'shade': 'bower_components/shade/dist/shade.min',
        'lockup': 'bower_components/lockup/dist/lockup.min',
        'deckard': 'bower_components/deckard/dist/deckard.min',
        'bouncefix': 'bower_components/bouncefix.js/dist/bouncefix.min',
        'velocity': 'bower_components/mobify-velocity/velocity',
        // or jQuery version 'velocity': 'bower_components/mobify-velocity/jquery.velocity',
        
        'drawer-left': 'bower_components/pikabu/dist/effect/drawer-left',
        'drawer-right': 'bower_components/pikabu/dist/effect/drawer-right'
        // There are a few more within the 'effect' folder
    }
}

And then require Pikabu in as needed:

define([
    'zepto',
    'modal-center',
    'pikabu'
    ],
    function($, modalCenter) {
        $('.pikabu').pikabu({
            effect: modalCenter
        });
    }
);

Usage

Pikabu requires very minimal markup. All Pikabu needs is a div with your content and it will automatically transform into what we need.

To avoid any unwanted FOUT, decorate the content you will be passing to Pikabu with the hidden attribute. We will remove that attribute when Pikabu is initialized.

For accessibility and functional purposes, Pikabu will wrap all of your body content in a wrapping container. This could conflict with other plugins that alter your page's markup. If you're seeing issues, try initializing Pikabu after your other plugins. If you want to specify your own wrapping container, add a class of lockup__container to the element. This element should be a root level element to be effective. You can also pass Pikabu a container parameter.

Initializing the plugin

pikabu()

Initializes the pikabu.

$('#myPikabu').pikabu({
    effect: modalCenter
});

You can also initialize the Pikabu through the use of a data attribute. The attribute takes a value equal to the effect you want to use.

<div id="myPikabu" data-pikabu="sheet-bottom">

You must pass Pikabu an effect for it to work.

pikabu(options)

Initialize with options.

$('#myPikabu').pikabu({
    effect: sheetBottom,
    container: '#container',
    structure: {
        header: 'My Pikabu Title',
        footer: false
    },
    zIndex: 2,
    cssClass: 'my-pikabu-class',
    coverage: '100%',
    easing: 'swing',
    duration: 200,
    shade: {
        color: '#404040'
    },
    open: noop,
    opened: noop,
    close: noop,
    closed: noop
});

Options

effect

default: { open: noop, close: noop },

Specifies which effect module Pikabu should use when opening. Effect modules allow you to load specific functionality that tell Pikabu how to open and close. Available effect modules can be found in the dist/effect folder. Current effect modules include:

• Modal Center - opens Pikabu in the center of the screen
• Sheet Top - slides down from the top of the screen
• Sheet Bottom - slides up from the bottom of the screen
• Sheet Left - slides in from the left of the screen
• Sheet Right - slides in from the right of the screen

$('#myPikabu').pikabu({
    effect: sheetLeft
});

container

default: $container (lockup's container)

Specify the container Pikabu will be created within

$('#myPikabu').pikabu({
    container: $('#mainForm') // or container: '#mainForm'
});

appendTo

default: null

Specify the element Pikabu will be appended to. By default Pikabu will be appended to the lockup container. If you want it to be appended outside the lockup container, specify that element here.

$('#myPikabu').pikabu({
    appendTo: 'body'
});

structure

default: { header: '', footer: false }

Defines the structure to use for Pikabu. Specifically, Pikabu tries to build its own HTML structure if passed the default options.

If you want to have full control over the HTML of your Pikabu, including the header, footer, and content section, set structure: false. Setting structure: false will still allow the close event to be bound to any element that has the pikabu__close class, allowing you to specify the element that should trigger closing your Pikabu.

If you are using structure: false, you will need to structure your HTML to include the following elements (missing any elements will cause Pikabu to not function):

<div id="myPikabu" class="pikabu__wrapper" role="document" hidden>
    <div class="pikabu__header">
        <a class="pikabu__close">close</a>
    </div>
    <div class="pikabu__content pikabu--is-scrollable"></div>
    <div class="pikabu__footer"></div>
</div>

Please see below for available sub-options for header and footer.

structure.header

default: ''

Sets the header that Pikabu should use in its header bar. Valid values are:

• boolean - specifies no default header generated. If chosen, the user is required to specify the header markup themselves, including the appropriate class, pikabu__header. It will be expected that this will be a part of the element that is used to invoke pikabu.
• string - specifies the title text used in the header. The header structure will be generated automatically.
• html|element - specifies the HTML to be used for the header.

// generates no header
$('#myPikabu').pikabu({
    structure: {
        header: false
    }
});

or

// generates a default header with the title "My Pikabu"
$('#myPikabu').pikabu({
        structure: {
            header: 'My Pikabu'
        }
    });

or

$('#myPikabu').pikabu({
    structure: {
        header: '<header class="pikabu__header">My Pikabu<button class="pikabu__close">Close</button></header>'
    }
});

structure.footer

default: false

Sets the footer that Pikabu should use in its footer. Valid values are:

• boolean - specifies no default footer generated. If chosen, the user is required to specify the footer markup themselves, including the appropriate class, pikabu__footer.
• string - specifies the title text used in the footer. The footer structure will be generated automatically.
• html|element - specifies the HTML to be used for the footer.

// generates no footer
$('#myPikabu').pikabu({
    structure: {
        footer: false
    }
});

or

// generates a default footer with the contents "My Footer"
$('#myPikabu').pikabu({
    structure: {
        footer: 'My Footer'
    }
});

or

$('#myPikabu').pikabu({
    structure: {
        footer: '<footer class="pikabu__footer">My Footer</footer>'
    }
});

zIndex

default: 2

Sets the z-index value for Pikabu. Use this value if you need to specify a specific stacking order.

$('#myPikabu').pikabu({
    zIndex: 10
});

cssClass

default: ''

Sets a class to apply to the main Pikabu parent element for ease of styling.

#('#myPikabu').pikabu({
    cssClass: 'my-pikabu-class'
});

coverage

default: 80%

Sets the coverage value. This will allow you to specify that the pikabu covers only a portion of the screen.

$('#myPikabu').pikabu({
    coverage: '80%'
});

duration

default: 200

Sets the duration for the animation.

$('#myPikabu').pikabu({
    duration: 600
});

shade

default: {}

Specifies whether pikabu should use the shade overlay. You can pass options through to Shade using this property. For more information on available options, see the Shade documentation.

Warning: We currently force Shade's duration to match the one provided to Pikabu. This is to limit DOM thrashing as much as possible during Pikabu's animation. Pikabu hitches a little if we don't do this.

$('#myPikabu').pikabu({
    shade: {
        color: '#333333'
    }
});

easing

default: swing

Sets the easing for the animation. Pikabu takes all of the same easing properties that Velocity.js accepts.

• jQuery UI's easings and CSS3's easings ("ease", "ease-in", "ease-out", and "ease-in-out"), which are pre-packaged into Velocity. A bonus "spring" easing (sampled in the CSS Support pane) is also included.

• CSS3's bezier curves: Pass in a four-item array of bezier points. (Refer to Cubic-Bezier.com for crafing custom bezier curves.)
• Spring physics: Pass a two-item array in the form of [ tension, friction ]. A higher tension (default: 600) increases total speed and bounciness. A lower friction (default: 20) increases ending vibration speed.
• Step easing: Pass a one-item array in the form of [ steps ]. The animation will jump toward its end values using the specified number of steps.

For more information, check out Velocity's docs on easing.

$('#myPikabu').pikabu({
    easing: 'ease-in-out'
});
