Zebra Dialog  

A small, compact 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, compact (one JavaScript file, no dependencies other than jQuery 1.7.0+) , and highly configurable jQuery plugin for creating responsive modal dialog boxes, meant to replace native JavaScript alert, confirmation 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 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".

# the "--save" argument adds the plugin as a dependency in packages.json
npm install zebra_dialog --save

Zebra Dialog is also available as a Bower package. To install it use:

# the "--save" argument adds the plugin as a dependency in bower.json

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/zebra_dialog@1.4.0/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 overlay and the dialog box will be animated when closing.
animation_speed_show	integer	0	The speed, in milliseconds, by which the overlay 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 floating them to the right
custom_class	mixed	false	An extra class to add to the dialog box's container, useful for further customizing dialog boxes 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.
height	integer	0	By default, the height of the dialog box is automatically set and it is also influenced by the max_height property. Use this to set a fixed height, in pixels, for the dialog box.
keyboard	boolean	true	When set to true, pressing the ESC key will close the dialog box.
max_height	integer	0	The maximum height, in pixels, before the content in the dialog box is scrolled. If set to 0 the dialog box's height will automatically adjust to fit the entire content.
message	string		The message in the dialog box - this is passed as argument when the plugin is called.
modal	boolean	true	When set to true there will be a semitransparent overlay behind the dialog box, preventing users from clicking the page's content.
overlay_close	boolean	true	Should the dialog box close when the overlay is clicked?
overlay_opacity	double	.9	The opacity of the overlay (between 0 and 1)
position	mixed	['center', 'middle']	Position of the dialog box. Can be either center 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 // 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	100	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: {     src: 'http://myurl.com/',     width: 480,     height: 320,     scrolling: 'no'   } } Note that you should always set the iFrame's width and height and adjust the dialog box's width property accordingly 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 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)	Width of the dialog box By default, the width of the dialog box is set in the theme file. Use this property to override the default width at run-time. Must be an integer, greater than 0. Anything else will instruct the script to use the default value, as set in the theme file. Value should be no less than 200 for optimal output.

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 overlay. 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.

Methods

close()

Call this method to manually close a dialog box.

var dialog = new $.Zebra_Dialog('This is some information');

dialog.close();

update()

Use this method to adjust the dialog box's position after content is changed dynamically, at run-time.

var dialog = new $.Zebra_Dialog('This is some information');

// change the content in the dialog box
$('.ZebraDialog_Body').html('New content');

dialog.update();
