|
||
|
|
*
|
||
|
|
* jGrowl is a jQuery plugin implementing unobtrusive userland notifications. These
|
||
|
|
* notifications function similarly to the Growl Framework available for
|
||
|
|
* Mac OS X (http://growl.info).
|
||
|
|
*
|
||
|
|
* To Do:
|
||
|
|
* - Move library settings to containers and allow them to be changed per container
|
||
|
|
*
|
||
|
|
* Changes in 1.2.4
|
||
|
|
* - Fixed IE bug with the close-all button
|
||
|
|
* - Fixed IE bug with the filter CSS attribute (special thanks to gotwic)
|
||
|
|
* - Update IE opacity CSS
|
||
|
|
* - Changed font sizes to use "em", and only set the base style
|
||
|
|
*
|
||
|
|
* Changes in 1.2.3
|
||
|
|
* - The callbacks no longer use the container as context, instead they use the actual notification
|
||
|
|
* - The callbacks now receive the container as a parameter after the options parameter
|
||
|
|
* - beforeOpen and beforeClose now check the return value, if it's false - the notification does
|
||
|
|
* not continue. The open callback will also halt execution if it returns false.
|
||
|
|
* - Fixed bug where containers would get confused
|
||
|
|
* - Expanded the pause functionality to pause an entire container.
|
||
|
|
*
|
||
|
|
* Changes in 1.2.2
|
||
|
|
* - Notification can now be theme rolled for jQuery UI, special thanks to Jeff Chan!
|
||
|
|
*
|
||
|
|
* Changes in 1.2.1
|
||
|
|
* - Fixed instance where the interval would fire the close method multiple times.
|
||
|
|
* - Added CSS to hide from print media
|
||
|
|
* - Fixed issue with closer button when div { position: relative } is set
|
||
|
|
* - Fixed leaking issue with multiple containers. Special thanks to Matthew Hanlon!
|
||
|
|
*
|
||
|
|
* Changes in 1.2.0
|
||
|
|
* - Added message pooling to limit the number of messages appearing at a given time.
|
||
|
|
* - Closing a notification is now bound to the notification object and triggered by the close button.
|
||
|
|
*
|
||
|
|
* Changes in 1.1.2
|
||
|
|
* - Added iPhone styled example
|
||
|
|
* - Fixed possible IE7 bug when determining if the ie6 class shoudl be applied.
|
||
|
|
* - Added template for the close button, so that it's content could be customized.
|
||
|
|
*
|
||
|
|
* Changes in 1.1.1
|
||
|
|
* - Fixed CSS styling bug for ie6 caused by a mispelling
|
||
|
|
* - Changes height restriction on default notifications to min-height
|
||
|
|
* - Added skinned examples using a variety of images
|
||
|
|
* - Added the ability to customize the content of the [close all] box
|
||
|
|
* - Added jTweet, an example of using jGrowl + Twitter
|
||
|
|
*
|
||
|
|
* Changes in 1.1.0
|
||
|
|
* - Multiple container and instances.
|
||
|
|
* - Standard $.jGrowl() now wraps $.fn.jGrowl() by first establishing a generic jGrowl container.
|
||
|
|
* - Instance methods of a jGrowl container can be called by $.fn.jGrowl(methodName)
|
||
|
|
* - Added glue preferenced, which allows notifications to be inserted before or after nodes in the container
|
||
|
|
* - Added new log callback which is called before anything is done for the notification
|
||
|
|
* - Corner's attribute are now applied on an individual notification basis.
|
||
|
|
*
|
||
|
|
* Changes in 1.0.4
|
||
|
|
* - Various CSS fixes so that jGrowl renders correctly in IE6.
|
||
|
|
*
|
||
|

|
||
|
|
* - Customizable animation easing.
|
||
|
|
* - Added customizable positioning (top-left, top-right, bottom-left, bottom-right, center)
|
||
|
|
*
|
||
|
|
* Changes in 1.0.2
|
||
|
|
* - All CSS styling is now external.
|
||
|
|
* - Added a theme parameter which specifies a secondary class for styling, such
|
||
|
|
* that notifications can be customized in appearance on a per message basis.
|
||
|
|
* - Notification life span is now customizable on a per message basis.
|
||
|
|
* - Added the ability to disable the global closer, enabled by default.
|
||
|
|
* - Added callbacks for when a notification is opened or closed.
|
||
|
|
* - Added callback for the global closer.
|
||
|
|
* - Customizable animation speed.
|
||
|
|
* - jGrowl now set itself up and tears itself down.
|
||
|

||
|
