Zepto.js 0.1.1: JS-based inheritance, .load, .is, $(document).ready, $.os

November 1st, 2010

We just pushed the next beta release of Zepto.js, and we’ve added a lot of stuff, and fixed some bugs on the way:

- Switch to JavaScript inheritance-based extension mechanism; this makes Zepto faster and allows plugins to be loaded lazily
– Add .load(url [, callback]) and .load('url #fragment-selector' [, callback]) to load HTML fragments with an Ajax call
– Add $(document).ready(callback) for calling methods when the DOMContentLoaded event fires
– Add .is(selector) for testing if the first element in the Zepto object matches a given selector

For most cases, these work like the corresponding function calls in jQuery.

Also new:

- Add a $.os object for info on which browser/platform is used. For example, on an iPad, $.os.ipad and $.os.ios is true, plus the current iOS version will be found in the $.os.version property

Thanks to the contributors and the community feedback for Zepto.js.

We’re still early into development of Zepto.js, but got a cool shout out from Ars Technica here (they’re rolling their own micro-framework for their iPad Reader app, but mention Zepto.js as a great option!).

Have you build anything way cool with Zepto.js? We’d love to showcase/link to your demos and apps from the Zepto.js site!
