Announcing the JavaScript Master Class: Virtual Edition, June 24!

We've been doing the legwork. We've learned what it takes to put on a kick-ass live, online class. (Don't call it a "webinar" -- or I'll be forced to show you the error of your ways!) The maiden voyage of the JavaScript Master Class: Virtual Edition will take place on June 24 2010, from 10am to 5pm London (GMT) time.

All you need is a reasonably snappy computer, good solid broadband, the latest version of Flash (sorry!), and your fine self. Our class schedule will include snack/pee breaks, and a lunch break. Our voices and screen presentations will come at you live! We'll take questions and solve problems. You will have a few exercises to work on, and we'll help you debug them if the need arises! And, because the online dynamic's a bit different, we'll be sending you the class materials in advance so you can peruse & prepare.

Previous attendees have described our workshops as "worth every penny" and "extremely good" and "I learned a lot and slowly started to feel my brain dribble out of my ears... in a good way." You will learn absolute gobs of stuff about JavaScript: The Language that will help you every day, no matter whether you use Prototype, jQuery, Node.js, or any other library -- or none at all.

See http://javascriptmasterclass.com/ for details &emdash; but don't book until you've read the bit about your discount!

This version is recommended for all users.

• Update to Prototype 1.6.0.3
• Make sure InPlaceEditor converts HTML entities to text. [Sean Kirby]
• Fix that Builder.node did not return extended elements on IE. Closes #71 and #77.
• Fix a bug in Sortable.destroy to make sure it's called on the referenced Sortable only, which allows for the correct intialization of nested Sortables. Closes Trac #8615. [Leon Chevalier]
• Change Effect.Base#render not to use eval(), so certain JavaScript runtime environments (like Adobe AIR) that do not support eval() work. [King Maxemilian, John-David Dalton]
• Fixed a calculation error in Effect.Transitions.pulse that could lead to flickering, add easing and change it to be a normal 0 to 1 transition that can be used with any effects; Effect.Pulsate now uses its own implementation. [Thomas Fuchs]
• Fixed Effect.ScrollTo. Changeset 8686 had a typo, document.viewport.getScrollOffsets[0] is always undefined. Removed the max check as it is not a cross-browser way to get scroll height and breaks the effect. Depending on scrollTo to do the right thing. Closes #11306. [Nick Stakenburg]
• Update version check so all Prototype versions can be required, not just x.x.x. Closes #10966. [Nick Stakenburg]
• Using $$ in the loader instead of getElementsByTagName to prevent limitations. Closes #9032. [Nick Stakenburg]
• Fix some missing semicolons. [jdalton]
• Fix an issue with Effect.ScrollTo that caused Firefox to scroll to the wrong offset in some situations. Closes #10245. [nik.wakelin]
• Fixes an issue with IE ghosting on non-absolute elements. Closes #10423. [Tanrikut, tdd]

Why git instead of Subversion? Well, it simply rules supreme, and makes working with many distributed developers with lots of branches a snap. You can find a good intro book on Git on Peepcode.

script.aculo.us 1.xx development will focus on bug fixes only, while I’m working on the next version of scripty (post on that coming up soon!).

Bug tracker http://prototype.lighthouseapp.com/projects/8887-script-aculo-us

Repository for script.aculo.us 1.xx http://github.com/madrobby/scriptaculous

Note that if you’re just using the library, this change won’t really affect you.

If you have open bugs on the old Trac please port them over to lighthouse yourself!

I’m also working on a replacement for the documentation wiki (which, quite honestly, sucks); so stay tuned for some updates in the near future. If you want to help out with the documentation effort, please contact me. :)

Mainly, this release contains some important bug fixes and optimizations in Prototype, fixes cursor keys in autocompleting text fields for IE and Safari plus fixes an issue with Effect.Morph on IE.

Download at http://script.aculo.us/downloads!

The included final 1.6.0 version of Prototype brings the latest and greatest awesome new features -- be sure to check it out on the Prototype site.

See the announcement for more information and a download link!

The included final 1.5.1 version of Prototype brings the latest and greatest in new cool features and performance gains, so be sure not miss this one. :)

Beta warning: Things might not work as you might expect, though they really should—if you hit any problems, please use the bug tracker and give reports. The same that applies to Prototype applies for script.aculo.us too, so read the how to contribute page to see how you can help out!

The most important change is the update to Prototype 1.5.1 which yields major performance improvements, slick new JSON support and various fixes all around. Note that the version of Prototype that comes with script.aculo.us 1.7.1 beta 1 is actually a few steps ahead of the 1.5.1_rc1 release and already incorporates a few additional fixes, so please use the version that comes with the script.aculo.us download.

The other important feature is experimental sound support for those little .mp3-based sound effects, which works natively in IE, and relies on whatever mp3 plugins are available on other browsers (for Macs, this means quicktime). It’s thought as an alternative to flash-based mp3 playback for sounds effects (not music!). Kudos to Jules Gravinese for coming up with the initial implementation of this!

The effects engine has seen some performance overhaul, and together with the new Prototype performance goodnees is screaming fast. Also, a memory leak in the morph code was found and fixed on Firefox. More changes and features added include a new “failure” option to Draggables, and onDropped callback, more customization for in-place editing, and nesting single nodes in the DOM builder.

See the complete announcement for more information and a download link!

* Update to Prototype 1.5.0 final

* Change the default setting for effects to support up to 60fps, if renderable by the browser. Add performance info to effects unit test.

* Add hash and CSS className support to Effect.Morph, fixes #6674 [Tobie]
    Examples:
      $(element).morph('myClass')
      // will morph to all the properties specified
      // in .className (in your external stylesheet).
      // All properties which cannot be morphed (such as font-style)
      // will be applied AfterFinish
      $(element).morph('font-size: 10px')  // or
      $(element).morph({fontSize: '10px'}) // will morph the font-size to 10px
      
* Add Element.morph() and Element.Methods.morph() as a shortcut to Effect.Morph
    Example:
      // basic Effect.Morph
      $('error_message').morph('color:#f00;font-size:17px');
      // fade out after a while
      $('error_message').show().morph('font-size:17px').morph('opacity:0',{delay:4});

* Add Effect.Transform that generates parallel executing Effect.Morph sets
    Example:
      // set up transformation
      var transformation = new Effect.Transform([
        { 'div.morphing': 'font-size:20px;padding-left:40em' },
        { 'blah'        : 'width:480px;border-width:10px;border-right-width:20px;margin:200px;margin-bottom:-20px;font-size:30px' }
      ],{ duration: 0.5 });
      // play transformation (can be called more than once)
      transformation.play();

* Add Effect.Morph core effect that morphs to a given CSS style rule. Effect.Morph does take orginal styles given by CSS style rules or the style attribute into consideration when calculating the transforms. It works with all length and color based CSS properties, including margins, paddings, borders, opacity and text/background colors.
    Example:
      new Effect.Morph('mydiv',{
        style: 'font-size:3em;color:#f00;border-width:2em',
        duration: 2.0
      });
      
* New option keepBackgroundImage: true for Effect.Highlight, fixes #5037 [docwhat, tomg]

* Minor tweaks for issues with application/xhtml+xml documents on Firefox, fixes #6836 [sjinks]

* Fix a possible exception with Sortables, fixes #6828 [craiggwilson]
      
* Add a paramName option to the inplace editor for overriding the default parameter name of "value"

            

Bugs in beta 1 where also addressed, especially Opera compatibility.

As always, kudos to the community for supplying patches, bug reports and tests—keep it coming!

script.aculo.us 1.6.4, which marks the inclusion of the new release candidate of Prototype 1.5, is out now.

(For those of you missing the 1.6.3 version: that version was out yesterday but had a issue with IE that is now fixed in 1.6.4)

This release comes with the brand-new Prototype V1.5.0_rc1 version, adds several new features and options to drag and drop, features a whole new (experimental) way of doing testing, and adds some other goodies here and there. Also, thanks to the contributors for identifying and squishing bugs!
