jQuery 1.7 Release

jQuery 1.7 is out. The official blog post has great coverage of this release, with some intriguing statistics on delegated event performance:

To optimize the code for the most commonly used forms of selectors, we examined a cross-section of code from Google Code Search… By parsing those simple selectors in JavaScript at the time the event was attached, we were able to outperform even the browser’s native-code implementations of matchesSelector during event delivery.


Doubletake (License: WTFPL) by Graham Bird changes the src of image elements based on the browser’s width. To control which images are requested, “breakpoints” are used to correctly match the file name:

  'breakpoints': [480,960],
  'pattern': '/images/foobar.jpg?width=([0-9]+)'

Graham’s example includes the use of Sencha Src to automatically resize images.

ThemeRoller for Mobile

ThemeRoller for Mobile has been released, which is a version of jQuery UI’s ThemeRoller for jQuery Mobile.

It also includes Adobe Kuler support for easily creating a colour palette for your apps.

Although themes can be shared, the links to shared themes are only saved for 30 days to “keep our server from getting stuffed with themes”.
