Zebra Dialog

A small, compact, mobile-friendly and highly configurable jQuery plugin for creating responsive modal dialog boxes

A modal window is a child window that requires users to interact with it before they can continue using the parent application. Modal windows are one of the most commonly used user interface elements and are used to command user awareness in order to communicate important information, or to alert of errors or warnings.

Zebra Dialog is a small (~10KB minified, 3KB gzipped), compact (one JavaScript file, no dependencies other than jQuery 1.7.0+), mobile-friendly and highly configurable jQuery plugin for creating responsive modal dialog boxes, meant to replace native JavaScript alert, confirm and prompt dialog boxes.

Can also be used as a notification widget (when configured to show no buttons and to close automatically) for updates or errors, without distracting users from their browser experience by displaying obtrusive alerts.

Features

great looking dialog boxes, out of the box, with 3 beautiful themes included
6 types of dialog boxes available: confirmation, error, information, prompt, question and warning
content can also be added through AJAX calls, iFrames or from inline elements (together with attached events)
easily customisable appearance by editing the CSS file
create modal or non-modal dialog boxes
easily add custom buttons
position the dialog box wherever you want - not just in the middle of the screen
callback functions can be used for further customisations
use callback functions to handle users' choice
works on mobile devices
works in pretty much any browser (Chrome, Firefox, Safari, Edge, Opera, Internet Explorer 6+)

For the classic theme, the icons used for confirmation, information, error and question dialog boxes are made by DryIcon while the warning icon is made by Function Design & Development Studio.

For the flat theme, the icons used are made by Elegant Themes

For the materialize theme theme, the icons used are taken from Google's Material Design "design language".

How to use

First, load jQuery from a CDN and provide a fallback to a local source like:

<script src="https://code.jquery.com/jquery-3.3.1.min.js"></script> <script>window.jQuery || document.write('<script src="path/to/jquery-3.3.1.js"><\/script>')</script>

Load the Zebra Dialog jQuery plugin:

<script src="path/to/zebra_dialog.min.js"></script>

Alternatively, you can load Zebra Dialog from JSDelivr CDN like this:

<!-- for the most recent version, not recommended in production --> <script src="https://cdn.jsdelivr.net/npm/zebra_dialog@latest/dist/zebra_dialog.min.js"></script>  <!-- for a specific version --> <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/zebra_dialog.min.js"></script>  <!-- replacing "min" with "src" will serve you the non-compressed version -->

Load the style sheet file from a local source

<link rel="stylesheet" href="path/to/theme/zebra_dialog.min.css">

...or from JSDelivr CDN

<!-- for the most recent version of the "flat" theme --> <link   rel="stylesheet"   href="https://cdn.jsdelivr.net/npm/zebra_dialog@latest/dist/css/flat/zebra_dialog.min.css">  <!-- for the most recent version of the "default" theme --> <link   rel="stylesheet"   href="https://cdn.jsdelivr.net/npm/zebra_dialog@latest/dist/css/default/zebra_dialog.min.css">  <!-- replacing "min" with "src" will serve you the non-compressed version -->

Now, within the DOM-ready event do

$(document).ready(function() {      // show a dialog box when clicking on an element     $('#element').on('click', function(e) {         e.preventDefault();         new $.Zebra_Dialog('The link was clicked!');     });  });

Configuration options

Properties

Property	Type	Default	Description
`animation_speed_hide`	integer	250	The speed, in milliseconds, by which the backdrop and the dialog box will be animated when closing.
`animation_speed_show`	integer	0	The speed, in milliseconds, by which the backdrop and the dialog box will be animated when appearing.
`auto_close`	mixed	false	The number of milliseconds after which to automatically close the dialog box or `false` to not automatically close the dialog box.
`auto_focus_button`	mixed	true	The index (0-based) of the button (from left to right) to place the focus on when a dialog box is first shown. Set to `false` to disable. When set to `false` the focus will be placed on the dialog box's content so that when the users presses `TAB`, the focus will be set on the first button. Setting this to `true` is equivalent to setting it to `0`. Default is TRUE
`buttons`	mixed		Use this for localization and for adding custom buttons. If set to `true`, the default buttons will be used, depending on the type of the dialog box: `['Ok', 'Cancel']` for `prompt`, `question` and `warning` types, and `['Ok']` for the other types of dialog boxes. For custom buttons, use an array containing the captions of the buttons to display: `['My button 1', 'My button 2']`. Set to `false` if you want no buttons. You can also add custom CSS classes, set which button's callback to be triggered when the user presses ENTER while inside the input box (for `prompt` dialog boxes), and/or attach callback functions to individual buttons by using objects in the form of: `[{` `caption: 'My button 1',` `custom_class: 'foo',` `default_confirmation: true,` `callback: function() { // code }` `},{` `caption: 'My button 2',` `custom_class: 'bar',` `callback: function() { // code }` `}]` For `prompt` dialog box types use the `default_confirmation` property to tell the library which button's callback to trigger when the user presses `ENTER` while inside the input box. If not set, you will have to handle user input via the `onClose` event, or you will not be able to process user input for this case. Callback functions receive as first argument the entire dialog box, as a jQuery object, and as second argument, the value entered in the input box - when the dialog box's type is `prompt`, or `undefined` for the other dialog types. A callback function attache to a button is executed as soon as the button is clicked rather than after the dialog box is closed, as it is the case with the `onClose` event. A callback function returning FALSE will prevent the dialog box from closing.
`center_buttons`	boolean	false	Setting this property to `true` will instruct the plugin to center any available buttons instead of aligning them to the right
`custom_class`	mixed	false	An extra class to add to the dialog box's container and to the backdrop (when present). For example, setting this value to `mycustom` and in the CSS file having something like `.mycustom .ZebraDialog_Title { background: red }` would set the dialog box title's background to red. Take a look into a theme's style sheet file to see what can be changed.
`default_value`	string	"" (empty string)	Default value to show in the input box when the dialog box type is `prompt`.
`disable_page_scrolling`	boolean	true	Prevents scrolling of the page behind the dialog box, when the dialog box is open. This has effect only when the `modal` property is set to `true`.
`height`	mixed	0 (automatically set)	By default, the height of the dialog box is automatically computed to fit the content (but not exceed viewport). Can be specified as a numeric value (which will be interpreted as a value in pixels) or as a percentage (of the viewport). If `max_height` is set to valid value greater than `0`, then this property will be ignored!
`keyboard`	boolean	true	When set to `true`, pressing the `ESC` key will close the dialog box.
`margin`	mixed	0	Margin of the dialog box relative to the viewport's limits (a single value, applied both horizontally and/or vertically) This is used when the dialog box is stretched 100% horizontally and/or vertically and `width` and `max_width` are not set (when stretched horizontally) and `height` and `max_height` are not set (when stretched vertically). This propery is also taken into account when using the `position` property. Can be specified as a numeric value (which will be interpreted as a value in pixels) or as a percentage (of the viewport).
`max_height`	mixed	0	The maximum height of the dialog box. Can be specified as a numeric value (which will be interpreted as a value in pixels) or as a percentage (of the viewport). If this property is set to valid value greater than `0`, then the `height` property will be ignored.
`max_width`	mixed	450	The maximum width of the dialog box. Can be specified as a numeric value (which will be interpreted as a value in pixels) or as a percentage (of the viewport). If this property is set to valid value greater than `0`, then the `width` property will be ignored.
`message`	string		The text (or HTML) to be displayed in the dialog box. See the `source` property on how to add content via AJAX, iFrames or from inline elements.
`modal`	boolean	true	When set to `true` there will be a semitransparent backdrop behind the dialog box, preventing users from clicking the page's content.
`backdrop_close`	boolean	true	Should the dialog box close when the backdrop is clicked?
`backdrop_container`	string	body	A selector indicating the DOM element to server as the backdrop's container.
`backdrop_opacity`	double	.9	The opacity of the backdrop (between `0` and `1`)
`position`	mixed	'center'	Position of the dialog box. Can be either `center` (which would center the dialog box both horizontally and vertically), or an array with 2 elements, in the form of `// notice that everything is enclosed in quotes` `['horizontal_position +/- offset',` `'vertical_position +/- offset']` where horizontal_position can be `left`, `right` or `center` vertical_position can be `top`, `bottom` or `middle` offset is optional and represents the value of pixels to add/subtract from the respective horizontal or vertical position Positions are relative to the viewport (the area of the browser that is visible to the user) and the value of the `margin` property is taken into account! Examples: `// position the dialog box in the top-left corner` `// shifted 20 pixels inside` `['left + 20', 'top + 20']` `// position the dialog box in the bottom-right corner` `// shifted 20 pixels inside` `['right - 20', 'bottom - 20']` `// position the dialog box in center-top` `// shifted 20 pixels down` `['center', 'top + 20']`
`reposition_speed`	integer	500	The duration (in milliseconds) of the animation used to reposition the dialog box when the browser window is resized.
`show_close_button`	boolean	true	When set to `true`, a close button (the little "x") will be shown in the upper right corner of the dialog box. If the dialog box has a title bar then the close button will be shown in the title bar, vertically centered and respecting the right padding. If the dialog box does not have a title bar then the close button will be shown in the upper right corner of the body of the dialog box, respecting the position related properties set in the stylesheet.
`source`	mixed	false	Add content via AJAX, iFrames or from inline elements (together with the already applied events). This property can be any of the following: `ajax: object` - where object can be an `object` with any of the properties you'd normally use to make an AJAX call in jQuery (see the description for the settings argument here), or it can be a `string` representing a valid URL whose content to be fetched via AJAX and placed inside the dialog box. `source: {ajax: 'http://myurl.com/'}` `source: {` `ajax: {` `url: 'http://myurl.com/',` `cache: false` `}` `}` Note that you cannot use the `success` property as it will always be overwritten by the library; use the `complete` property instead, if you have to `iframe: object` - where object can be an `object` where property names are valid attributes of the iframe tag, or it can be a `string` representing a valid URL to be loaded inside an iFrame and placed inside the dialog box. `source: {iframe: 'http://myurl.com/'}` `source: {` `// iFrame's width and height are automatically set` `// to fit the dialog box's width and height` `iframe: {` `src: 'http://myurl.com/'` `}` `}` `inline: selector` - where element is a jQuery element from the page; the element will be copied and placed inside the dialog box together with any attached events. If you just want the element's inner HTML, use `$('#element').html()` `source: {inline: $('#myelement')}`
`title`	string	"" (empty string, no title)	Title of the dialog box
`type`	mixed	information	Dialog box type. Can be any of the following: confirmation error information prompt question warning If you don't want an icon, set the `type` property to `false`. By default, the `warning` and `question` types have two buttons with the captions Ok and Cancel respectively, while the other types have a single button with the caption Ok.
`vcenter_short_message`	boolean		Should short messages be vertically centered?
`width`	integer	0 (uses the value defined in the theme)	By default, the width of the dialog box is automatically computed in order to fit the content (but not exceed viewport. Can be specified as a numeric value (which will be interpreted as a value in pixels) or as a percentage (of the viewport). If `max_width` is set to valid value greater than `0`, then this property will be ignored.

Events

Event Description

onClose Event fired when after the dialog box is closed.

For executing functions before the closing of the dialog box, see the buttons option.

The callback function receives as first argument the caption of the clicked button or boolean FALSE if the dialog box is closed by pressing the ESC key, by clicking the dialog box's x button, or by clicking the backdrop. The argument can also be boolean TRUE when the dialog box type is prompt and the ENTER key is pressed while inside the input box.

As second argument, the callback function receives the value entered in the input box - when the dialog box type is prompt and a button was clicked or the ENTER key was pressed while inside the input box, or undefined for any other case.

All this is important when expecting user input as you can say that you have user input only when the value of the first argument is boolean TRUEor the value it's the same as the label of the button considered as confirmation (i.e. "Ok"), and the value of the second argument is !== undefined.

See the buttons property for another way of handling user input.
