Add support for :nth-of-type()

[wenz]

The :nth-of-type CSS selector has been removed in jQuery 1.0. Given that recent browsers do support querySelector() and thus also support :nth-of-type(), I believe it would be a good idea to add :nth-of-type for legacy browsers. For instance, the example at ​http://jsfiddle.net/Kr5yN/3/ works in all current browsers and IE9+, but fails in IE6-8.

Nothing has changed since it was removed. A fallback for legacy browsers is still needed, and it's still a pretty obscure selector, and not worth the extra bloat. In most cases nth-child can be used instead.

If you really need it with jQuery, you can use this plugin: ​https://github.com/keithclark/JQuery-Extended-Selectors or this: ​http://css-tricks.com/snippets/jquery/add-nth-of-type-to-jquery/

Seems like a rare selector need to me. If you're in a situation where all the platforms you support provide querySelectorAll you can use it.

Since this is really a Sizzle issue, I'll leave it open for timmywil's call.

I'm ok with adding it, but I think we should do some voting. There wouldn't be much extra bloat since we can reuse :nth-child's argument parsing, which has the same syntax.

I'm okay with it if it's only a few bytes, since it's a cross-browser issue.

This issue has been ported to a more widespread sizzle issue: ​https://github.com/jquery/sizzle/issues/44
