New Plugin Repository

Posted on by

jQuery Plugin Repository

One of the great aspects of jQuery is its extensibility, as evidenced by the many excellent plugins that have been developed for it. The jQuery team, and the Web team in particular, have been working hard behind the scenes to put together a repository to showcase these plugins.

The new repository comes with a few features that are sure to help users to find what they’re looking for and determine which plugins will best suit their needs. There’s the (jQuery-based) ratings widget to let you know how highly others value each plugin. The ratings are viewable by all, and you can rate them yourself by simply registering on the site with a user name and email address. You’ll also have easier access to change logs, demos, and documentation, as well as bug reporting and feature requests.

There are still a few rough edges to be smoothed out, and the list of plugins on the site is admittedly small so far. We’re requesting that plugin authors post their work to the new plugin repository in the next couple weeks, as we’ll be gradually phasing out the plugins wiki page.

Special thanks to Mike Hostetler for the hours of work he put in to get the repository off to a great start.

New Command-Line jQuery Tool

Posted on by

Update: I have completely refactored jcheat and added substantial new functionality, including a ton of filters that can be used in any combination. Do a gem update and run jcheat -h for full usage details.

I released a new tool, jquery-cheat, that allows you to get information about the jQuery API directly from the command-line. You can get the description of a function, a list of functions in each module, search the list of all function descriptions for a string, get a list of all functions whose name match a string, and some other cool tricks.

Some examples:

# jcheat desc clearForm
--------------------------------------------------------------------------------
Name:         clearForm()
Description:  Clears the form data.
              
Details:      Clears the form data.  Takes the following actions on the
              form's input fields:  - input text fields will have their
              'value' property set to the empty string  - select elements
              will have their 'selectedIndex' property set to -1  - checkbox
              and radio inputs will have their 'checked' property set to
              false  - inputs of type submit, button, reset, and hidden will
              *not* be effected  - button elements will *not* be effected
              
Returns:      jQuery
--------------------------------------------------------------------------------
|                                   EXAMPLES                                   |
--------------------------------------------------------------------------------
---------------
| Description |
---------------
Clears all forms on the page.

--------
| Code |
--------
$('form').clearForm();

# jcheat namelike $.ajax
$.ajaxTimeout(time) in Ajax
$.ajaxSetup(settings) in Ajax
$.ajax(properties) in Ajax

# jcheat like clear field
clearForm() in Plugins/Form
clearFields() in Plugins/Form

You can grab the tool by doing:

gem install jquery-cheat -y

The -y is so that it automatically includes hpricot, a required dependency.

jQuery Dashboard Widget

Posted on by

jQuery Widget

Ryan Dunphey has just released a brand new jQuery Dashboard Widget that you can use to browse the jQuery API, even when you’re not connected to the Internet. You can download the, sharply designed, widget from jQuery SVN.

If you’re interested in doing some dashboard development (and especially widget development using jQuery), you can learn from this widget, as the full source code of it is in the jQuery SVN repository.

This fantastic work (and the subsequent open source release of the widget) was sponsored by Ryan’s employer, Medallia. Incidentally, if you’re interested in getting paid to do some jQuery coding, Medallia has a Front-End Developer position open.

Servers, servers, and donations

Posted on by

The jQuery services are mostly back to normal now, John has since moved the jQuery SVN to Google Code and is working to move the remaining mailing lists to Google Groups. So, the most important parts have weathered the recent server move, no problem.

Of course, moving providers when a dedicated server is required usually brings with it a significant investment of capital. With that, we wanted to thank the jQuery community for springing to life and donating generously to help with the transition. In fact, the donations completely cover the initial cost of the new server.

Obviously, we don’t really push for donations around here, so it’s great to see so many lend a helping hand. Thank you all.

And now for some extra-good news!

MT hearts jQuery

Media Temple has stepped up to donate a great hosting package, to jQuery, complete with the industry-recognized support reputation preceding them. We anticipate being fully up-and-running on their hardware in the coming months, and welcome this new partnership and the benefits it will bring the jQuery community.

Help Test jQuery 1.1.3

Posted on by

A test build of the upcoming 1.1.3 release is ready for everyone to try. We need to be super-sure that there haven’t been any regressions in this release, and in order to do that we’d like you to download this alpha release and try it in place of jQuery 1.1.2 (wherever you may be using it).

Download the test release:


Here’s what you can do to help:

  1. Download the test release of jQuery 1.1.3
  2. Temporarily replace your copy of jQuery 1.1.2 with this test release in some of your web pages
  3. If something is now broken, please submit a ticket letting us know what happened. The more specific you can be, the better (demos or test cases are highly desired).

Note Pay special attention to Events, Selectors, and Animations; significant changes happened in all three of those areas, so if there’s any place where a regression is possible, it would be more likely to occur in there.

Once we’re confident that there’s no new bugs, we’ll be releasing jQuery 1.1.3 fully (hopefully some time this week).

jQuery Session at RailsConf

Posted on by

RailsConf 2007

I’m happy to announce that my proposal for a Birds of a Feather session about “jQuery on Rails” at RailsConf has been accepted!

If you’re at RailsConf, please come by room c125 on Thursday night at 9:30pm and join in the discussion. I’ll be chatting about my ongoing work on jQuery on Rails, and should have some code to demo if anyone would be interested.

If you’re interested in hearing about how others have solved problems regarding the integration of jQuery with Rails, or just want to share something cool you’ve done, swing on by. See you there!

More Details

Yehuda has just posted more details on how jQuery on Rails works:

Since I last publicly discussed jQuery on Rails, I’ve gone down a lot of avenues, and written a lot of code, and came to some conclusions:

  • jQuery and Unobtrusive JavaScript are fundamentally incompatible with an attempt to describe behavior inside markup, as Rails does via “JavaScript helpers.”
  • Attempts to fix the problem, specifically UJS for Rails, still require that you include your JS behaviors in your views, which are then marshalled into JavaScript files on the fly (and cached as appropriate). If you wanted to include the same JS behavior in multiple pages, you’d need to create custom helpers and call out to them.
  • jQuery is already the perfect mechanism for unobtrusive JavaScript, baked right into the library
  • The biggest problem faced by jQuery developers is not simplicity (which, again, you get for free in the library), but difficulty in including the correct jQuery “modules” in the Rails views that require them.

The most common problem with using jQuery with Rails in an app of moderate or higher complexity is the trade-off between including everything in a single application.js (which can lead to serious slowdowns in larger apps) and having multiple, modular files (which are a serious pain to include correctly as needed).

This is a problem for jQuery users who want to use Rails more than Rails users who are used to Prototype helpers and want to be able to use the jQuery library as a drop-in replacement. In the first release of jQuery on Rails, I will be targeting jQuery developers who want to work with Rails. In other words, jQuery on Rails is for you if you know jQuery or are willing to use jQuery.

This release of jQuery is not for you if you don’t want to learn jQuery, and want to program purely in Ruby. There will be a future release that will include some features for pure-Ruby developers, but I maintain that Unobtrusive JavaScript is fundamentally incompatible with that mode of thinking.

With all that said, what does jQuery on Rails actually do?

First up, it’s a Rails plugin, which you activate by adding <%= include_jquery %> in your application.rhtml. When your server is started, it’ll parse all of your JavaScript files, and identify selectors in those files. When include_jquery is called in your layout, it’ll get the rendered HTML and use Hpricot (which shares syntax with jQuery) to determine whether any instances of the selectors identified on server startup are present.

The JavaScript files that have selectors that are also present in your HTML will be loaded, and run as expected.

So in short:

  • Create your JavaScript files, using selectors as usual
  • Use include_jquery in your layout
  • You’re done

Fisheye Dock Menu

Fisheye Dock Menu

With a little bit of nice theming, the Fisheye component from Interface has been adapted to build a beautiful “CSS dock menu“. It’s currently making all the rounds on design blogs and on Digg.

Some more information about what this menu was designed for can be found on the developer’s site:

If you are a big Mac fan, you will love this CSS dock menu that I designed. It is using jQuery JavaScript library and Fisheye component from Interface and some of my icons. It comes with two dock styles – top and bottom. This CSS dock menu is perfect to add on to my WordPress iTheme. Here I will show you how to implement it to your web page.

Learning jQuery Book Details

Posted on by

This week Jonathan Chaffer and I finished the book’s first draft and sent the last chapter to the publisher, so I thought I’d take this opportunity before the revisions start rolling in to provide some more details. The book’s full title is Learning jQuery: Better Interaction Design and Web Development with Simple JavaScript Techniques. Learning jQuery bookAs the subtitle suggests, we’ve written the book to be accessible to those with a web-design background who haven’t had much, if any experience, with coding. But we think it will provide plenty of useful information for intermediate-level scripters as well.

The book is being published by PACKT Publishing, based in Manchester Birmingham, UK. They’re a relative newcomer to the publishing world, but already they’ve managed to put together a pretty impressive group of books, many of which explore open-source software projects. They seem passionate about supporting these projects beyond publishing books about them. In fact, they’ve introduced a royalty scheme that gives a percentage of sales to the open-source project that a book is written about. So, if you buy this book, you’ll be directly supporting the jQuery project. :)

The expected publication date is sometime this July, and the book is already available for pre-order at a 20% discount. The publisher plans to sell a PDF-version of the book, too, but they haven’t set it up for pre-order just yet.

Barring the unlikely major structural change during our revision phase, the (concise) table of contents should look like something like this:

  1. Introducing jQuery
    1. Getting Started
  2. Exploring jQuery
    1. Selectors, or How to Get Anything You Want
    2. Events, or How to Pull the Trigger
    3. Effects, or How to Add Flair to Your Actions
    4. DOM Manipulation, or How to Change Your Page on Command
    5. AJAX, or How to Make Your Site Buzzword Compliant
  3. Using jQuery
    1. Table Manipulation
    2. Forms with Function
    3. Shufflers and Rotators
  4. Examining jQuery
    1. Selector Expressions
    2. DOM Traversal Methods
    3. DOM Manipulation Methods
    4. Event Methods
    5. Effect Methods
    6. AJAX Methods
    7. Miscellaneous Methods
    8. Plug-ins
  5. Appendices
    1. Online Resources
    2. Development Tools
    3. JavaScript Closures

Update:

We’re making good progress on the revisions, and it looks like we’re going to hit our target publication date of July. The publisher has just made the PDF version of the book available for pre-order at a 15% discount. Also, they have a “Book and eBook Bundle” at an enormously discounted price (US $36.79).
