[jQuery] How to access contents of frames/iframes with jQuery?

[Kynn Jones]

Hi again!

(Second question in as many days...  I guess I'm the overeager noob.  :) )

Last night I watched John Resig's screencast "Hacking Digg with Firebug and
jQuery" ( highly recommended, BTW:
http://ejohn.org/blog/hacking-digg-with-firebug-and-jquery/ ) and I
immediately went to one of my favorite webapps and tried to put to use the
ideas he presented, but right out of the gate I crashed against frames.

Or at least I think that's what the problem was.  For example, when I tried
to evaluate jQuery expressions like $("div"), the result printed by Firebug
was [ ], even though, according to Firebug's inspector, the page I was
trying to dissect had plenty of divs.  (BTW, this seemed odd to me, since it
seems somehow to go against the "find things, do stuff" philosophy.)

Anyway, I did get reasonable-looking results when I tried $("frameset") and
$("frame"), but I can't figure out how to get past this point.

(BTW, I did try Firefox's "Show only this frame" command, but the server
basically vetoes the request and sends all the frames anyway.)

So my question is, can jQuery handle frames?  More specifically, what jQuery
functions would one use to find and manipulate the contents of a frame?

And what about iframes?

Thanks in advance!

PS: I scanned the documentation in http://docs.jquery.com/DOM/Traversing ,
but I didn't find an answer.

Thanks, John.  And thanks for jQuery.  Beautiful piece of work.

Hi Kynn -

Documentation on $.extend can be found here:
http://docs.jquery.com/JavaScript

and information on using $.fn.extend can be found here:
http://docs.jquery.com/Plugins/Authoring

In jQuery $.fn.extend is used in plugin authoring, adding new methods to
jQuery.

The relationship in jQuery is like this:
jQuery and $ are identical.
jQuery.fn and $.fn are identical.
jQuery.fn and jQuery.prototype are identical.
jQuery.extend and jQuery.fn.extend are nearly identical, but when you
pass in a single object of properties, jQuery.extend will extend the
jQuery object with properties whereas jQuery.fn.extend will extend the
jQuery.fn object (and thus add new methods to the jQuery core).

All of that being said, if you're just getting started with jQuery,
you're probably not going to have to worry about any of this.

[jQuery] ISO docs for $.fn ?

[Kynn Jones]

Hi.  I'm just learning about jQuery and finding my way around its
documentation.

I have not been able to find any documentation on $.fn.

In fact in some of the rest of the documentation (e.g. the example code for
$.extend given at  http://visualjquery.com/1.1.1.html, $.fn (or rather
jQuery.fn ) without explanation.

Actually, the examples given there raise many questions in my mind, for
example: what's the difference between $.fn and jQuery.fn?  And, what's the
difference between calling jQuery.fn.extend and jQuery.extend?

Are the answers to these questions in the documentation?  If so, please
point me to them.

Any help would be much appreciated.

TIA!
