jquery.alertable.js - Minimal alert, confirm, and prompt replacements.

Developed by Cory LaViska for A Beautiful Site, LLC

Overview:

This plugin provides a minimal, lightweight, and customizable alternative to window.alert() and window.confirm(). It's flexible enough to mold to your application's existing stylesheet and markup.

Features:

• Simple syntax:
  • $.alertable.alert('Howdy!')
  • $.alertable.confirm('You sure?').then(function() { ... })
  • $.alertable.prompt('How many?').then(function(data) { ... })
• Minimal default styles; easy to customize or write your own.
• Show/hide hooks for adding custom animation (works well with Velocity.js).
• Prevents focus from leaving the modal.
• Returns promise-compatible (jQuery deferred) for ok/cancel actions.
• Compact! (about 180 lines)

Installing

Include the minified version of this plugin in your project or install via NPM:

npm install --save @claviska/jquery-alertable

Using the plugin

Example alerts:

// Basic example
$.alertable.alert('Howdy!');

// Example with action when the modal is dismissed
$.alertable.alert('Howdy!').always(function() {
    // Modal was dismissed
});

Example confirmations:

// Basic example
$.alertable.confirm('You sure?').then(function() {
    // OK was selected
});

// Example with then/always
$.alertable.confirm('You sure?').then(function() {
    // OK was selected
}, function() {
    // Cancel was selected
}).always(function() {
    // Modal was dismissed
});

Example prompts:

// Basic example
$.alertable.prompt('How many?').then(function(data) {
    // Prompt was submitted
});

// Example with then/always
$.alertable.prompt('How many?').then(function(data) {
    // Prompt was submitted
}, function() {
    // Prompt was canceled
}).always(function() {
    // Modal was dismissed
});

Important: Unlike window.alert(), window.confirm(), and window.prompt(), using this plugin will not cause execution of the script to stop while the modal is open. This behavior is not possible to emulate with a plugin nor is it desirable in modern web applications.

Options

Pass options as the second argument of any method:

$.alertable.alert('Howdy!', {
    optionName: optionValue,
    ...
});

$.alertable.confirm('You sure?', {
    optionName: optionValue,
    ...
});

$.alertable.prompt('How many?', {
    optionName: optionValue,
    ...
});

Available options:

• container: The container to append the modal to. Defaults to 'body'.

• html: Whether or not your message contains HTML. Defaults to false.

• cancelButton: HTML to use for the reject button. Default value:

<button class="alertable-cancel" type="button">Cancel</button>

• okButton: HTML to use for the resolve button. Default value:

<button class="alertable-ok" type="button">OK</button>

• overlay: HTML to use for the overlay. Default value:

<div class="alertable-overlay"></div>

• prompt: HTML to use for the prompt body. All inputs contained in this HTML will be serialized and returned when the prompt is submitted. Default value:

<input class="alertable-input" type="text" name="value">

• modal: HTML to use for the modal. Default value:

<div class="alertable">
    <div class="alertable-message"></div>
    <div class="alertable-buttons"></div>
</div>

• hide: Function for hiding the modal and overlay. Use this.modal and this.overlay to reference the modal and overlay elements. Default value:

$(this.modal).add(this.overlay).fadeOut(100);

• show: Function for showing the modal and overlay. Use this.modal and this.overlay to reference the modal and overlay elements. Default value:

$(this.modal).add(this.overlay).fadeIn(100);

You may also update the default options before calling either method:

$.alertable.defaults.optionName = yourValue;

Promises

Both alert and confirm return a promise-compatible (jQuery-deferred) object. As a result, you can use any of the supported chainable methods. However, the examples above demonstrate the most appropriate ones to use.
