cannot access links in an iframe

oscar1martin

The property document.links seems to access links inside a frame, but
not an iframe. For instance, the following code displays a "4": 2
links in main page, 2 links in frame1.
<body onload="fn()">
<script type="text/javascript">
function fn()
{
alert(document. links.length)
}
</script>

<a href="http://somewhere1">aaa </a>
<a href="http://somewhere2">bbb </a>

<frameset>
<frame name="frame1" id="frame1">
<a href="http://somewhere3">ccc </a>
<a href="http://somewhere4">ddd </a>
</frame>
<iframe name="frame2" id="frame2" src="http://somewhere5">
</iframe>
</frameset>

</body>
Is there a way to access the links in the iframe?

Thanks in advance.

It reports exactly what is found. Now, whether or not you understand
your markup is an entirely different thing.

<a href="http://somewhere1">aaa </a>
<a href="http://somewhere2">bbb </a>

<frameset>
<frame name="frame1" id="frame1">
<a href="http://somewhere3">ccc </a>
<a href="http://somewhere4">ddd </a>
</frame>
<iframe name="frame2" id="frame2" src="http://somewhere5">
</iframe>
</frameset>

</body>

How do you expect JavaScript to behave the way you want it to if you do
not provide it valid HTML?

Yes. You must first however embed it properly in a page. For example,
in a frame, in a frameset.

Well, yes, I guessed I could be doing something wrong, but what is it?

I have skimmed trhough hundreds of examples on the net and they all
seem like mine to me.
Also, the page displays correctly.

Some more help, please?

Start with valid HTML: http://validator.w3.org/

Avoid frames: http://allmyfaqs.net/faq.pl?Problems_with_using_frames

In you insist on using frames, use them according to the standard:
http://www.w3.org/TR/html4/present/frames.html

Now, this is a helpful answer. And a proof that there are a few things
I have to learn.

Thanks to both of you.

I've seen warnings on Google's site about indexing problems when using frames.
Although Google does seem to index pages using iframes without any problems as long
as you provide non-iframe support information.

Browser manufacturers, browsers and browser versions do not skimmed
through hundreds of examples on the web. What they do is read the HTML
4.01 spec and then try to follow and comply with the HTML 4.01 spec.

HTML 4.01 technical recommendation
http://www.w3.org/TR/html4/cover.html

The frameset element can only have <frame>(s), <frameset>(s) or
<noframeselemen ts. The frameset element can not have an <iframe>, like
in your posted code. That's what the HTML 4.01 spec says.

http://www.w3.org/TR/html4/present/frames.html#h-16.2.1

And this chunk of markup code (taken from your original post):
<frame name="frame1" id="frame1">
<a href="http://somewhere3">ccc </a>
<a href="http://somewhere4">ddd </a>
</frame>
is invalid.

Some more help, please?

Don't use <frame>s, don't use <framesetand don't use <iframeas these
are bad for accessibility, search/indexing, bookmarking.

With people now upgrading to newer browsers or newer browser versions
which can support position: fixed, there is no good reason anymore to
use frames. If we knew exactly what you are trying to do along with an
url, we could be able to better help you.
