Bootstrap Modal v2.2.5

See live demo here.

Extends Bootstrap’s native modals to provide additional functionality. Introduces a ModalManager class that operates behind the scenes to handle multiple modals by listening on their events.

A single ModalManager is created by default on body and can be accessed through the jQuery plugin interface.

$('body').modalmanager('loading');

Bootstrap-Modal can be used as a replacement for Bootstrap’s Modal class or as a patch to the library.

Bootstrap 3

If you’re using BS3, I’ve provided a compatible css patch. Include bootstrap-modal-bs3patch.css before the main bootstrap-modal.css file to use this plugin with Bootstrap 3.

If you’re using the loading spinner functionality you may also need to change the default template to be compatible in js:

$.fn.modal.defaults.spinner = $.fn.modalmanager.defaults.spinner = 
    '<div class="loading-spinner" style="width: 200px; margin-left: -100px;">' +
        '<div class="progress progress-striped active">' +
            '<div class="progress-bar" style="width: 100%;"></div>' +
        '</div>' +
    '</div>';

Note: Since this plugin was created to solve a lot of the issues with BS2, it still uses the BS2 markup syntax. Currently I believe the default BS3 modal addresses some of the bigger issues and is not worth maintaining two versions of this plugin.

Overview

  • Backwards compatible
  • Responsive
  • Stackable
  • Full width
  • Load content via AJAX
  • Disable background scrolling

Installation

  • Include css/bootstrap-modal.css after the main bootstrap css files.

  • Include js/bootstrap-modalmanager.js and js/bootstrap-modal.js after the main bootstrap js files.

Options

In addition to the standard bootstrap options, you now have access to the following options

Modal

  • width Set the inital width of the modal.

  • height Set the inital height of the modal.

  • maxHeight Set the max-height of the modal-body.

  • loading Toggle the loading state.

  • spinner Provide a custom image or animation for the loading spinner.

  • backdropTemplate Provide a custom modal backdrop.

  • consumeTab Used to enable tabindexing for modals with data-tabindex. This is set to true by default.

  • focusOn The element or selector to set the focus to once the modal is shown.

  • replace If set to true, the modal will replace the topmost modal when opened.

  • attentionAnimation Set the animation used by the attention method. Any animation in animate.css is supported but only the shake animation is included by default.

  • modalOverflow Set this property to true for modals with highly dynamic content. This will force the modal to behave as if it is larger than the viewport.

  • manager Set the modal’s manager. By default this is set to the GlobalModalManager and will most likely not need to be overridden.

ModalManager

  • loading Toggle the loading state.

  • backdropLimit Limit the amount of backdrops that will appear on the page at the same time.

  • spinner Provide a custom image or animation for the loading spinner.

  • backdropTemplate Provide a custom modalmanager backdrop. This backdrop is used when $element.modalmanager('loading') is called.

Disable Background Scrolling

If you want to prevent the background page from scrolling (see demo for example) you must wrap the page contents in a <div class="page-container">. For example:

<body>
	<div class="page-container">
		<div class="navbar navbar-fixed-top">...</div>
		<div class="container">...</div>
	</div>
</body>

The reason for doing this instead of just simply setting overflow: hidden when a modal is open is to avoid having the page shift as a result of the scrollbar appearing/disappearing. This also allows the document to be scrollable when there is a tall modal but only to the height of the modal, not the entire page.

Constrain Modal to Window Size

You can bind the the height of the modal body to the window with something like this:

$.fn.modal.defaults.maxHeight = function(){
    // subtract the height of the modal header and footer
    return $(window).height() - 165; 
}

Note: This will be overwritten by the responsiveness and is only set when the modal is displayed, not when the window is resized.

Tab Index for Modal Forms

You can use data-tabindex instead of the default tabindex to specify the tabindex within a modal.

<input type="text" data-tabindex="1" />
<input type="text" data-tabindex="2" />

See the stackable example on the demo page for an example.
