Highlights

Fix an XSS attack vector: User ma.la reported a common pattern that many sites are using to select elements using location.hash that allows someone to inject script into the page. This practice seemed widespread enough that we decided to modify the selector recognition to prevent script injection for the most common case. Any string passed to $() cannot contain HTML tags (and thus no script) if it has a “#” character preceding them. See the ticket linked above for more information and a test case.

No more animation “worm holes”: We had high hopes for the browser’s requestAnimationFrame API when we added support into version 1.6. However, one of the highest-volume complaints we’ve received since then relates to the way requestAnimationFrame acts when a tab is not visible. All the animations initiated when the tab is invisible “stack” and are not executed until the tab is brought back into focus. Then they all animate at warp speed! We’ve removed support for this API (which has no impact on the way you call jQuery’s animation features) and plan to incorporate it into a future version of jQuery.

Better handling of HTML5 data attribute names: The $().data() API serves double-duty, handling data for the internal use of jQuery and plugins in addition to reading initial values of HTML5 data- attributes. We’ve improved the ability to use HTML5 conventions such as converting camel-case to camelCase when needed. Remember, however, that the $().data() API only reads the HTML5 data- attributes initially, and does not keep subsequent data changes in sync with attributes for performance reasons. To update the actual attributes in the HTML markup, use .attr().

Back in 2007 we released the jQuery Color Plugin, and it has been providing you with color-based animations ever since. We are now preparing a second version of this plugin which adds an API, RGBA, HSLA, and many other features. It is time for a beta! The repository for this plugin can be found at github.com/jquery/jquery-color.  There are also uncompressed and minified versions available on code.jquery.com.

New Feature Overview:

RGBA

We now support RGBA color values. In browsers that don’t support RGBA, the nearest backgroundColor to the element will be used to calculate a “blended” approximation of the color. Although this isn’t “true” alpha, it will at least provide the illusion of alpha when dealing with solid background colors.  This is a screenshot of Opera 10, Chrome 10, Firefox 3.6, and IE 6 all running this demonstration of alpha blending:

HSLA

We also now support using HSLA color values across all browsers, with the execption of alpha, which uses the same techniques described above.

Easy-to-use API

Instead of a simple group of private utility methods, $.Color() now creates a new Color object. The new Color object can be initialized in a few different ways: color names, hexidecimal color codes, css style rgba/hsla, an array of rgba values, or an object with the color properties. There are now helper methods for each color property, like .red() and .hue() that can get or set the particular value. Combined with helper functions like .toRgbString(), .transition() and .is(), $.Color can now handle whatever color needs you might have. Refer to the README on github.com/jquery/jquery-color for an overview of all the new functions available. No longer is jQuery.Color just providing you with animation of simple colors, you can now use its API to do complex color calculations and animations!

Quick Examples:

// Create a red Color object:
var red = $.Color( 'rgba(255,0,0,1)' ); // using a css string

// Create a red Color object, then make orange:
var orange = $.Color( '#FF0000' ).green( 153 );

// Get the color halfway between red and blue:
var between = $.Color([ 255, 0, 0 ]).transition( "blue", 0.5 );

Animating Partial Colors

We have added support for only defining one or two properties of a color object so that you can animate using a partial color like this:

// desaturate the background of this element
elem.animate({
    backgroundColor: $.Color({ saturation: 0 })
}, 1000);

Reporting Problems / Requesting Features:

If you find any problems with the new color plugin, or would like to request a feature, please create a github issue.

Also, we’d love to see and showcase some excellent uses of the new $.Color beta, so please be sure to share it with us in the comments.
