The Modal

The goal of this jQuery plugin is to implement modal boxes.

If the box is modal then:

• Page itself should not be scrollable.
• Modal box content should be scrollable independent of the page.

Facebook and vk.com photo modals are working like that and I think it's the right way to go.

Before describing features and API here's the demo.

Features

• No extra markup required.
• You can use it w/o markup at all by opening empty modal and filling it with custom data the way you want (see below).
• Optional close on ESC (enabled by default).

More to come.

Usage

In order to use this plugin you need the following in the head section of your HTML:

<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script type="text/javascript" src="jquery.the-modal.js"></script>
<link rel="stylesheet" type="text/css" href="the-modal.css" media="all" />

HTML-markup as modal content

HTML:

<div class="modal" id="terms-of-service" style="display: none">
		<a href="#" class="close">×</a>

		Terms of service here
</div>

JavaScript:

// attach close button handler
$('.modal .close').on('click', function(e){
	e.preventDefault();
	$.modal().close();
});

// open modal with default options or options set with init
// content will be taken from #login
$('#terms-of-service').modal().open();

// also we can open modal overriding some default options
$('#terms-of-service').modal().open({
	closeOnESC: false
});

// Close modal. There's no need to choose which one since only one can be opened
$.modal().close();

Custom content

$.modal().open({
	onOpen: function(el, options){
		el.html('Hello!');
	}
});

AJAX-content

$.modal().open({
	onOpen: function(el, options){
		$.get('http://example.com/', function(data){
			el.html(data);
		});
	}
});

Available options (default values)

$.modal({
	/* css class of locked container(body) */
	lockClass: 'themodal-lock',

	/* css class of overlay */
	overlayClass: 'themodal-overlay',

	/* close modal on press ESC */
	closeOnEsc: true,

	/* close overlay when clicked on it */
	closeOnOverlayClick: true,

	/* callback function(overlay, localOptions){}, called before modal close,
	must be return bool(if true - close, if false - prevent closing) */
	onBeforeClose: null,

	/* callback function(overlay, localOptions){}, called after modal close */
	onClose: null,

	/* callback function(overlay, localOptions){}, called after modal open */
	onOpen: null,

	/* clone modal dom element on open or toggle it's visibility */
	cloning: true
});

Overriding options

// set option as default for all modals opened
$.modal({
	closeOnESC: true
});

// set some default options for specific dom element
$('#login').modal({
	closeOnESC: true,
	onClose: function(el, options) {
		alert('Closed!');
	}
});

Known issues to be fixed

• FF scrolls page instead of modal content when pressing cursor keys and PGUP, PGDWN. If content of the modal is clicked once, it works fine.
• After scrolling down all modal content iOS Safari is starting scrolling page content.
