Make selectors work across iframes

[paul]

I propose to add navigating through iframes for the immediate next version of jQuery. That would basically allow you to do stuff like $("iframe div") and fail gracefully on iframes you're not allowed to access.

Although I never worked on the selector engine, implementation seems quite easy - a initial test showed that adding something like

if(ret[i].nodeName.toLowerCase() == "iframe") ret[i] = ret[i].contentDocument

ret[i].document;

at line 232 in selector.js would do the job (probably not in all cases though). I personally think it would be a very valuable addition, and I can see quite a few usecases in jQuery UI.

I can add that some people asked me how to scroll (using scrollTo/localScroll) to items in iframes when links on parent win are clicked. This would do the trick.

There are some restrictions with cross domain iframes, right ? that needs to be taken into account.

Since it's not possible to navigate through cross-domain iframes, jQuery would simply return a empty collection in that case.

The standard querySelectorAll selector syntax tdoesn't support this so I'm closing it.
