Do skip links work in Chrome? I have one of our developers saying that he can't get skip links to work correctly within Chrome. If you click the skip link, it appears to move focus to the internal anchor on the page, but if you tab then it acts as though the keyboard focus is still on the skip link at the top of the page.

Thanks!

What is the syntax your developer is using?

I have found that the following syntax (with tabindex="-1") works the
best:

<a href="#main">Skip to main</a>
...
<a name="main" id="main" tabindex="-1">

The example Jason gave works on Chrome for Windows. I recently competed in an accessible web design competition and did a lot of cross-browser, OS, and mobile device testing.

I found a skip link that works for Safari and Chrome on Mac. Requires JavaScript though. It will display on those browsers the visible text "Start of Content" so you may not like this but I think it could be placed off the page with CSS positioning. The live example is at http://pauljadam.com/bluemistband

<p><a href="#contentstart" id="skiplink">Skip to Content</a></p>


<p><a id="contentstart" tabindex="-1"></a></p>

<!-- This is the skiplink javascript. This makes the skip link work for WebKit browsers (e.g. Safari and Chrome. It must appear after both the skip link and skip target, so the bottom of the page is best -->
<script type="text/javascript">
//<![CDATA[
var is_webkit = navigator.userAgent.toLowerCase().indexOf('webkit') > -1;
var is_opera = navigator.userAgent.toLowerCase().indexOf('opera') > -1;
if(is_webkit || is_opera)
{
var target = document.getElementById('contentstart');
target.href="#contentstart";
target.innerText="Start of Content";
target.setAttribute("tabindex" , "0");
document.getElementById('skiplink').setAttribute("onclick" , "document.getElementById('contentstart').focus();");
}

More: tabindex isn't an attribute that can be applied to a div, so if a
skip nav is anchored to a div id, the tabindexs="-1" solution isn't
available.

W3C specs:

Elements that may receive focus should be navigated by user agents
according to the following rules:

Those elements that support the tabindex attribute and assign a positive
value to it are navigated first. Navigation proceeds from the element with
the lowest tabindex value to the element with the highest value. Values
need not be sequential nor must they begin with any particular value.
Elements that have identical tabindex values should be navigated in the
order they appear in the character stream.
Those elements that do not support the tabindex attribute or support it
and assign it a value of "0" are navigated next. These elements are
navigated in the order they appear in the character stream.
Elements that are disabled do not participate in the tabbing order.
The following elements support the tabindex attribute: A, AREA, BUTTON,
INPUT, OBJECT, SELECT, and TEXTAREA.


So, actually, the -1 is out of spec. And it would seem that tabindex=0
would do the trick. However, in Safari 5 under OSX 10.6 , neither
tabindex="-1 or tabindex="0" applied to a named anchor moves the keyboard
focus for me when I test it Š wish it would!

This is puzzling and raises a fundamental question: Do links that
point to content within the same Web page not work on these browsers?
What's so special about a skip nav link... apart from the fact that it
aids keyboard navigation and may or may not be visible? It is a link
with its target set to some other part of the page and should work
without a hitch without any extra JS code.
So do all same-page links fail on these browsers?

That's according to HTML 4. ARIA overrides this rule to allow tabindex
on any element and allow values of 0 or -1
(http://www.w3.org/TR/2010/WD-wai-aria-practices-20100916/#kbd_focus).

Indeed tabindex of 0 or -1 doesn't really make sense on elements that
are already keyboard navigable. I guess you could use tabindex=-1 to
remove an element from the natural taborder, though I can think of no
situation where this would be a good idea.

Of note is that these values have been supported for this behavior in
all major browsers starting with IE5.

Yep. As Paul noted, this is a significant oversight/bug that is
currently being addressed in Safari, thus the JavaScript enhancement
that sets explicit focus to these elements (which, again, is only
possible with tabindex=-1).

Yes.

More accurately, Safari (even with VoiceOver enabled) and Chrome on
Mac set visual focus (scroll the browser viewport), but do not change
the tab focus to that position in the page (if you press Tab again,
tab focus is set back to the next link after the same-page link).

This is a failure an not a bug. Firefox and IE are the only two
browsers on the Windows platform that provide visual focus with
keyboard focus when selecting an in-page anchor.

It's a UAAG issue and not a WCAG issue.
