Boost JS Modal
A style-free and accessible modal plugin for jQuery and Boost JS. This plugin only includes styles absolutely necessary for the modal to work properly, the rest is up to you.
Installation
Install with npm:
npm install boost-js-modal
Install in browser:
<script src="https://cdn.rawgit.com/marksmccann/boost-js-modal/v0.1.1/dist/modal.min.js"></script>
AND include styles:
<link rel="stylesheet" href="https://cdn.rawgit.com/marksmccann/boost-js-modal/v0.1.1/dist/modal.min.css">
Usage
Create Plugin
var boost = require('boost-js');
// var boost = $.fn.boost; (browser install)
var modal = require('boost-js-modal');
// var modal = $.fn.boost.modal; (browser install)
$.fn.modal = boost( modal.plugin, modal.defaults );
Markup Structure
<div id="modal">
<h2 data-bind="#modal" data-role="heading">Heading</h2>
<button data-bind="#modal" data-role="close">Close</button>
</div>
<button data-bind="#modal" data-role="open">Open</button>
Tip: Add style="display:none;"
to your source element if your modal is momentarily visible before the app is able to hide it; the attribute will be removed after instantiation.
Note: data-bind
is used to link the element to the instance, data-role
is used to define the element's role in that instance. See Boost JS for more details.
