# Why another modal plugin?



Most plugins I've found try to do too much, and have specialized ways of handling photo galleries, iframes and video.  The resulting HTML & CSS is often bloated and difficult to customize.



By contrast, this plugin handles the two most common scenarios I run into



* displaying an existing DOM element

* loading a page with AJAX



and does so with as little HTML & CSS as possible.



# Installation



You can install [jquery-modal](https://www.npmjs.com/package/jquery-modal) with npm:



`npm install jquery-modal`



or with [Bower](http://bower.io/):



`bower install jquery-modal`



or use the hosted version from [cdnjs](https://cdnjs.com/libraries/jquery-modal):



```html



```



**Using Rails?** Check out the [jquery-modal-rails plugin](https://github.com/dei79/jquery-modal-rails)!



**jQuery Requirements:** As of version 0.3.0, jQuery 1.7 is required. If you're using an earlier version of jQuery you can use the [v.0.2.5 tag.](https://github.com/kylefox/jquery-modal/tags)



**Naming conflict with Bootstrap:** Bootstrap's [modal](http://getbootstrap.com/javascript/#modals) uses the same `$.modal` namespace. If you want to use jquery-modal with Bootstrap, the simplest solution is to manually modify the name of this plugin.



# Opening



#### Method 1: Automatically attaching to links



The simplest approach is to add `rel="modal:open"` to your links and use the `href` attribute to specify what to open in the modal.



Open an existing DOM element by ID:



```html



  ...



Login

```



Load a remote URL with AJAX:



```html

Login

```



#### Method 2: Manually



You can manually open a modal by calling the `.modal()` method on the element:



```html



  ...



```



```js

$('#login-form').modal();

```



You can also invoke `.modal()` directly on links:



```html

Open a DOM element

Open an AJAX modal

```



```js

$('a[data-modal]').click(function(event) {

  $(this).modal();

  return false;

});

```



### Compatibility Fallback



You can provide a clean fallback for users who have JavaScript disabled by manually attaching the modal via the `data-modal` attribute. This allows you to write your links pointing to the `href` as normal (fallback) while enabling modals where JavaScript is enabled.



```html



Login





  ...




  $(function() {

    $('a[data-modal]').on('click', function() {

      $($(this).data('modal')).modal();

      return false;

    });

  });



```



#### Fade Transitions



By default the overlay & window appear instantaneously, but you can enable a fade effect by specifying the `fadeDuration` option.



```js

$('a.open-modal').click(function(event) {

  $(this).modal({

    fadeDuration: 250

  });

  return false;

});

```



This will fade in the overlay and modal over 250 milliseconds _simultaneously._ If you want the effect of the overlay appearing _before_ the window, you can specify the `fadeDelay` option. This indicates at what point during the overlay transition the window transition should begin.



So if you wanted the window to fade in when the overlay's was 80% finished:



```js

$(elm).modal({

  fadeDuration: 250,

  fadeDelay: 0.80

});

```



Or, if you wanted the window to fade in a few moments after the overlay transition has completely finished:



```js

$(elm).modal({

  fadeDuration: 250,

  fadeDelay: 1.5

});

```



The `fadeDelay` option only applies when opening the modal. When closing the modal, both the modal and the overlay fade out simultaneously according to the `fadeDuration` setting.



Fading is the only supported transition.



# Closing



Because there can be only one modal active at a single time, there's no need to select which modal to close:



```js

$.modal.close();

```



Similar to how links can be automatically bound to open modals, they can be bound to close modals using `rel="modal:close"`:



```html

Close window

```



_(Note that modals loaded with AJAX are removed from the DOM when closed)._



# Checking current state



* Use `$.modal.isActive()` to check if a modal is currently being displayed.

* Use `$.modal.getCurrent()` to retrieve a reference to the currently active modal instance, if any.



# Options



These are the supported options and their default values:



```js

$.modal.defaults = {

  closeExisting: true,    // Close existing modals. Set this to false if you need to stack multiple modal instances.

  escapeClose: true,      // Allows the user to close the modal by pressing `ESC`

  clickClose: true,       // Allows the user to close the modal by clicking the overlay

  closeText: 'Close',     // Text content for the close  tag.

  closeClass: '',         // Add additional class(es) to the close  tag.

  showClose: true,        // Shows a (X) icon/link in the top-right corner

  modalClass: "modal",    // CSS class added to the element being displayed in the modal.

  blockerClass: "modal",  // CSS class added to the overlay (blocker).



  // HTML appended to the default spinner during AJAX requests.

  spinnerHtml: '






',



  showSpinner: true,      // Enable/disable the default spinner during AJAX requests.

  fadeDuration: null,     // Number of milliseconds the fade transition takes (null means no transition)

  fadeDelay: 1.0          // Point during the overlay's fade-in that the modal begins to fade in (.5 = 50%, 1.5 = 150%, etc.)

};

```



# Events



The following events are triggered on the modal element at various points in the open/close cycle (see below for AJAX events).



```javascript

$.modal.BEFORE_BLOCK = 'modal:before-block';    // Fires just before the overlay (blocker) appears.

$.modal.BLOCK = 'modal:block';                  // Fires after the overlay (block) is visible.

$.modal.BEFORE_OPEN = 'modal:before-open';      // Fires just before the modal opens.

$.modal.OPEN = 'modal:open';                    // Fires after the modal has finished opening.

$.modal.BEFORE_CLOSE = 'modal:before-close';    // Fires when the modal has been requested to close.

$.modal.CLOSE = 'modal:close';                  // Fires when the modal begins closing (including animations).

$.modal.AFTER_CLOSE = 'modal:after-close';      // Fires after the modal has fully closed (including animations).

```



The first and only argument passed to these event handlers is the `modal` object, which has four properties:



```js

modal.$elm;       // Original jQuery object upon which modal() was invoked.

modal.options;    // Options passed to the modal.

modal.$blocker;   // The overlay element.

modal.$anchor;    // Anchor element originating the event.

```



So, you could do something like this:



```js

$('#purchase-form').on($.modal.BEFORE_CLOSE, function(event, modal) {

  clear_shopping_cart();

});

```



# AJAX



## Basic support



jQuery Modal uses $.get for basic AJAX support. A simple spinner will be displayed by default (if you've included modal.css) and will have the class `modal-spinner`. If you've set the `modalClass` option, the spinner will be prefixed with that class name instead.



You can add text or additional HTML to the spinner with the `spinnerHtml` option, or disable the spinner entirely by setting `showSpinner: false`.



The default spinner is from the excellent [SpinKit](http://tobiasahlin.com/spinkit/) by [Tobias Ahlin](https://twitter.com/tobiasahlin) 👍



## Events



The following events are triggered when AJAX modals are requested.



```js

$.modal.AJAX_SEND = 'modal:ajax:send';

$.modal.AJAX_SUCCESS = 'modal:ajax:success';

$.modal.AJAX_FAIL = 'modal:ajax:fail';

$.modal.AJAX_COMPLETE = 'modal:ajax:complete';

```



The handlers receive no arguments. The events are triggered on the `` element which initiated the AJAX modal.



## More advanced AJAX handling



It's a good idea to provide more robust AJAX handling -- error handling, in particular. Instead of accommodating the myriad [`$.ajax` options](http://api.jquery.com/jQuery.ajax/) jQuery provides, jquery-modal makes it possible to directly modify the AJAX request itself.



Simply bypass the default AJAX handling (i.e.: don't use `rel="modal"`)



```html

Click me!

```



and make your AJAX request in the link's click handler. Note that you need to manually append the new HTML/modal in the `success` callback:



```js

$('a[rel="ajax:modal"]').click(function(event) {



  $.ajax({



    url: $(this).attr('href'),



    success: function(newHTML, textStatus, jqXHR) {

      $(newHTML).appendTo('body').modal();

    },



    error: function(jqXHR, textStatus, errorThrown) {

      // Handle AJAX errors

    }



    // More AJAX customization goes here.



  });



  return false;

});

```



Note that the AJAX response must be wrapped in a div with class modal when using the second (manual) method.



# Bugs & Feature Requests



### Found a bug? MEH!



![](http://drops.kylefox.ca/1cqGP+)



**Just kidding.** Please [create an issue](https://github.com/kylefox/jquery-modal/issues/new) and **include a publicly-accessible demonstration of the bug.** [Dropbox](https://www.dropbox.com) or [JSFiddle](http://jsfiddle.net/) work well for demonstrating reproducable bugs, but you can use anything as long as it's publicly accessible. Your issue is much more likely to be resolved/merged if it includes a fix & pull request.



**Have an idea that improves jquery-modal?** Awesome! Please fork this repository, implement your idea (including documentation, if necessary), and submit a pull request.



I don't use this library as frequently as I used to, so if you want to see a fix/improvement you're best off submitting a pull request. Bugs without a test case and/or improvements without a pull request will be shown no mercy and closed!



# Contributing



## Maintainers Wanted



![](https://img.shields.io/badge/maintainers-wanted-red.svg)



This library became more popular and active than I ever expected, and unfortunately I don't have time to maintain it myself.



If you are interested in helping me maintain this library, please let me know — **I would love your help!**



[**Read more about becoming a maintainer »**](https://github.com/kylefox/jquery-modal/issues/170)



_I'd especially like people who would be excited about working towards a brand new **jQuery Modal 2.0**. See my [Proposal for jQuery Modal 2.0](https://github.com/kylefox/jquery-modal/issues/169) for more details & discussion._



## How to contribute



I welcome improvements to this plugin, particularly with:



* Performance improvements

* Making the code as concise/efficient as possible

* Bug fixes & browser compatibility



Please fork and send pull requests, or create an [issue](https://github.com/kylefox/jquery-modal/issues). Keep in mind the spirit of this plugin is **minimalism** so I'm very picky about adding _new_ features.



## Tips for development/contributing



* Make sure dependencies are installed: `npm install`

* After modifying `jquery.modal.js` and/or `jquery.modal.css`, you can optionally regenerate the minified files with `gulp min` and `gulp css` respectively.

* Make sure you have updated documentation (`README.md` and/or `examples/index.html`) if necessary. **Pull requests without documentation updates will be rejected.**

* Maintainers should increment version numbers and run `gulp changelog` when cutting a new release.
