Overview:

This plugin provides a minimal, lightweight, and customizable notification API for showing unobtrusive announcements in various styles. It's flexible enough to mold to your application's existing stylesheet and markup.

Features:

• Simple syntax:
  • $.announce.info('Hello there!')
  • $.announce.danger('Delete this?')
  • $.announce.success('All done?')
  • $.announce.warning('Are you sure?')
• Minimal default styles; easy to customize or write your own.
• Show/hide hooks for adding custom animation (works well with Velocity.js).
• Responsive
• Works well with Bootstrap and other frameworks
• Compact! (about 110 lines)

Demo

A quick demo can be found on CodePen: http://codepen.io/claviska/pen/EZrrZz

Installing

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

npm install --save @claviska/jquery-announce 

Using the plugin

// Minimal example $.announce.info('Hi there!');  // Example with options $.announce.info({   message: 'Well <em>hello</em> there!',   duration: 2000,   hideOnClick: true,   html: true });

Methods

The following announcements are included by default:

• $.announce.info(options)
• $.announce.danger(options)
• $.announce.success(options)
• $.announce.warning(options)

There is also a method to create custom announcements:

• $.announce.say('your-custom-type', options)

In this case, the resulting announcement will be assigned the following classes that you can use for styling purposes: announce announce-your-custom-type

Note: By design, only one announcement will ever be shown at a time. Multiple notifications (i.e. stacking or growl-style) are outside the scope of this micro-plugin.

Options

If options is a string, it will be used as the message. If options is an object, it will be merged with $.announce.defaults.

Available options:

• className: The class name to assign to the announcement.
• duration: The length of time in milliseconds to show the announcement.
• hideOnClick: If true, the announcement will be hidden when the user clicks on it.
• html: If true, HTML will not be escaped when setting the message.
• show: Function for showing the announcement. Use this to reference the announcement element. Must return a promise-compatible object that resolves when the promise is completely visible. (This promise is currently not used, but is included for future enhancements.) Default value:

  function() {   var defer = $.Deferred();   $(this).fadeIn(250, function() {     defer.resolve();   });   return defer; }

• hide: Function for hiding the announcement. Use this to reference the announcement element. Must return a promise-compatible object that resolves when the announcement is completely hidden. Default value:

  function() {   var defer = $.Deferred();   $(this).fadeOut(250, function() {     $(this).remove();     defer.resolve();   });   return defer; }

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

$.announce.defaults.optionName = yourValue;

Promises

All announcements return a promise-compatible (jQuery-deferred) object that will resolve once the announcement is completely hidden:

$.announce.info('Hi there!').then(function() {   console.log('Dismissed!'); });
