New method: $.fn.classlist()

[Rick Waldron]

Essentially, a jQuery method that wraps the brains of classList where available and provides a fallback where it isn't available. I'll provide more details via jsfiddle's when I get a chance.

I guess you mean the HTML 5 classList.

For reference:

​HTML5: classList and ​HTML5: DOMTokenList

​Mozilla element.classList

​Webkit svn

[Rick Waldron]

yes, thats what I'm thinking. Thanks for posting the resource info

Additionally, I put together these minimal requirements:

Should: feature detect (adds a test for classList to jQuery.support), normalize functionality for both native and non-native, support classList functionality

I spent the morning writing a draft of this and will have a repo available soon. Its very tight so far and offers: item(), add(), remove(), contains() and toggle() - using jQuery's own methods

Additionally, I have 59 unit tests written. Will start writing an api doc asap so it can be use tested.

Since addClass/removeClass etc is the abstraction jQuery provides for classes, why wouldn't those methods just use elem.classList if available for the added perf?

Changing the API for class manipulation as a sort of polyfill seems like its not really jquery's style.

I should've updated this ticket some time ago. Yes - thats the direction I've taken - no new api, but perf boosts where possible.
