The BEST jQuery Modal, Alert, Popup, Lightbox Plugin

jAlert is really easy, and really powerful! See why below:

Plenty-o Sizes

Completely responsive (just under full width on small screens), but for tablets and desktops, you have a lot of control over how large the alert is.

xsm sm md lg xlg full auto 20% 600px {'height':'100px', 'width':'300px'} {'height':'400px', 'width':'300px'}

Sweet Themes

When used correctly, a user may not even need to read your message to know what it pertains to. Red alert = error. Green = success. You can use the default black background, or optional white one.

default red dark_red green dark_green blue dark_blue yellow brown gray dark_gray black
default red dark_red green dark_green blue dark_blue yellow brown gray dark_gray black

Responsive Lightbox(es)

Need to show a video, image, iframe, or something fetched via AJAX? It's dead-simple and beautiful using jAlert:

Image Image no Pad Video Video no Pad iFrame iFrame no Pad iFrame fullscreen, no Pad AJAX

Blurred Background

Popup an alert and blur all the background elements:


CSS Animations

In version 3, Animate.css was integrated.

default fade bounce flip x flip y zoom

These are just a few. Checkout Animate.css for the full list (must choose ones that hide/show the element).

Closing Options

When it comes to closing jAlert, you have a few options (all of which can be disabled)

top-right btn alt esc key anywhere auto none


Additionally: With or without the background (btnBackground: boolean)

default red green blue black
default red green blue black


In version 3, a confirmation was added with callbacks for onConfirm and onDeny.


Easy Callbacks

There are callbacks for: alert "onOpen", alert "onClose", alert "onAjaxFail", and btn "onClick".

onOpen onClose onAjaxFail onClick

MIT Licensed

Go ahead and use jAlert in any commercial project you'd like. Just leave the MIT license intact to give credit where credit's due. If you really like jAlert, consider buying me a new car! (or like...a beer or something..) Thank you in advance!

Examples & Use-Cases

Instead of just giving you more of what's on the homepage, here are some advanced examples and use-cases that show how you can take full advantage of jAlert's functionality to build awesome apps.

Shortcut Functions (requires jAlert-functions.js)

alert('For your info...', ' rock!');
alert(' rock!'); //default is to not display a title
Need to show a success message?
successAlert('Success!', 'Saved your profile.');
successAlert('Saved your profile.'); //default title is Success
How about an error?
errorAlert('Error!', 'Could not save your profile.');
errorAlert('Could not save your profile.'); //default title is Error
Info anyone?
infoAlert('Info', 'I like your shirt.');
infoAlert('I like your shirt.'); //default title is Info
warningAlert('Warning', 'Your shirt is not yellow!');
warningAlert('Your shirt is not yellow!'); //default title is Warning
Black (like your ex wife's heart)
blackAlert('Warning', 'It\'s still got that new car smell.');
blackAlert('It\'s still got that new car smell.'); //default title is Warning
Confirmation anyone?
confirm(function(e,btn){ //event + button clicked
}, function(e,btn){
errorAlert('Could not save your profile.'); //default title is Error!

Link Css

Move the plugin CSS file to your server and link to it in the head section of your document.

<link rel="stylesheet" href="jAlert-master/dist/jAlert.css" />

Link JS

Move the plugin JS file to your server and link to it before the closing body tag.

Please note that you must include jQuery (v1.7 or later) before the jAlert JS file.

<script src="jquery-1.7.1.min.js"></script>
<script src="jAlert-master/dist/jAlert.min.js"></script>
<script src="jAlert-master/dist/jAlert-functions.min.js"> //optional!!</script>

Call Plugin

Just before the closing body tag (after any JS file includes), call the plugin with code below:

$(document).ready(function () {
        'title': 'It works!',
        'content': 'YAY!',
        'theme': 'green',
        'btns': { 'text': 'close' }

To use "data-jAlert" attributes to toggle jAlerts, use the attach function

This means you can add a button like this: <a href='#' data-jAlert data-title='Hi' data-content='I opened!'>Click me</a>

$(document).ready(function () {
Warning! The attach function binds to the current DOM. If you add elements dynamically, you must run attach again!

jAlert Settings

How to set options when calling jAlert:
  'title': 'Set It',
  'content': 'Set',
  'theme': 'green',
  'size': 'md',
  'showAnimation': 'fadeInUp',
  'hideAnimation': 'fadeOutDown'
If you're using the data-jAlert attributes (every options can be set this way, however, some (like callbacks) may not work):
<a href='#' data-jAlert data-title="Set It" data-content="Set" data-theme="green" data-size="md" data-showAnimation="fadeInUp" data-hideAnimation="fadeOutDown">
   Click Me
How to get the current top-most visible jAlert:
var currentAlert = $.jAlert('current');
//now that you've got it, you can get it's properties, or close it.
How to override defaults:
$.fn.jAlert.defaults.size = 'lg';
$.fn.jAlert.defaults.theme = 'blue';
$.fn.jAlert.defaults.showAnimation = 'fadeInUp';
$.fn.jAlert.defaults.hideAnimation = 'fadeOutDown';
Full list of available options
Property Default Options Description
title false string, false This is the title of the modal. If false, a title bar isn't shown.
content false string, false Content is ignored if you're using image, iframe, ajax, or video. If content is false and you don't provide one of those, an error will be console logged.
noPadContent false boolean By default, the content of an alert has padding. You may choose to remove this by setting this param to true. This is useful in situations where you want something like an Iframe to be the full size without padding.
fullscreen false boolean This option makes jAlert stretch to the full height and width of the current window. Useful for fullscreen iframes, images, or other content.
image false string (url), false Displays an image centered with a max-width: 100% (of the alert's width). Shows a loader until the image has loaded.
imageWidth 'auto' string (include % or px) Defines the width of the image. max-width is always 100%.
ajax false string (url), false Does a $.get request and puts the content in the alert. Shows a loader until the content has been put in the DOM. onOpen is called AFTER the content is retrieved.
onAjaxFail function(alert, errorThrown){ alert.closeAlert(); errorAlert(errorThrown); }; function What to do if the $.get request fails for ajax. Default closes the alert and displays the ajax error.
iframe false string (url), false Displays a full width iframe with no border. Show a loader until the iframe has loaded.
iframeHeight false string (px, %), false Controls the height of the iframe. False will calculate 90% of the viewport height.

id false string, false Sets an ID for div.jAlert
showAnimation 'fadeInUp' string, false Controls how to animate the entrance of the alert. Uses Animate.css (included in the CSS file).
hideAnimation 'fadeOutDown' string, false Controls how to animate the closing of the alert. Uses Animate.css (included in the CSS file).
animationTimeout 500 int Approx. how long the hide/show animation takes so that the background can wait and then hide. Since the animation is in CSS, there is no callback to rely on. If you change the animation speed in the CSS, you should change this to match.
theme 'default' string ('default', 'red', 'dark_red', 'green',' dark_green', 'blue', 'dark_blue', 'brown', 'gray', 'dark_gray', 'black') Controls the color of the title background, the border of the entire alert, and the font color of the title.
backgroundColor 'black' string ('black', 'white') Controls the color of the background behind the alert (the color that covers up the rest of the page).

size (width is an alias) 'sm' string ('xsm', 'xsmall', 'sm', 'small', 'md', 'medium', 'lg', 'large', 'xlg', 'xlarge', 'full', 'auto', {'height': '300px', 'width': '300px'}, 'npx', 'n%') If you need to know exact pixel sizes of each, they're in the CSS file. All sizes are max-width of just smaller than the viewport (aka..responsive). Auto adjusts to the size of the content. You can also pass an object with height and width OR just a width (px or %)
replaceOtherAlerts false boolean When opening an alert/this alert, should other alerts be removed first? (true = yes)
closeOnClick false boolean Whether or not to hide the alert when you click anywhere on the page (true = yes). This is disabled if you include buttons in your alert.

A btn object can contain the following properties:
Property Default Options Description
text '' string Required. This is the label for the button
href '' string (url) Where the button should navigate to. Not required if you plan to use the onClick callback and do something else.
target '_self' string ('_self', '_blank', '_parent', etc) The target window/tab for the link to open in.

denyBtnText 'No' string The deny button's text for type: 'confirm'.
confirmAutofocus '.confirmBtn' string ('.confirmBtn', '.denyBtn', dom selector) Autofocuses on the confirm button by default. You may pass any selector for a DOM element in the alert, or one of the two classes shown here. For type: 'confirm'.
