No previous message | Next message →

I'm using MAP for a navigation bar, as suggested by one of the web
accessibility sites.

Here is my code:


<MAP title="Navigation Bar">
[<a href="toc.htm">Contents</a>] [<a
href="question1.htm">Question 1</a>] [<a href="question3.htm">Question
3</a>] [<a href="glossary.htm">Glossary</a>]
</map>

However, I get this error when validating the code:

<MAP title="Navigation Bar">
Error: required attribute "NAME" not specified

Where did I go wrong? Should title be NAME?

This is rather urgent as the Simplified Web Accessibility Guide goes to
print today. Help.

Cheers,
Glenda

The NAME attribute is roughly equivalent to the ID attribute, not the
TITLE attribute. ID and NAME are both computer-readable tokens used
for hypertext links and the like. TITLE is a human-readable optional
label.

NAME is used in the IMG tag when you're making an imagemap, to tell
the browser which MAP to use. You probably want something
like:

<map title="Navigation Bar" name="navbar">

I personally am doubtful of the utility of using imagemap code to
mark up navigation bars, myself, but it probably isn't harmful.

You need the attribute "name" instead of "title"..that should do it :-)

Hi Glenda,

I suggest using DIV. MAP is a tag for image maps; you have a simple text
navigation bar. I'm sure MAP probably won't hurt, but I don't think this
was the intention of the MAP tag.

You can use TITLE attribute with the DIV:

<DIV title="Navigation Bar">
[<a href="toc.htm">Contents</a>] [<a
href="question1.htm">Question 1</a>] [<a href="question3.htm">Question
3</a>] [<a href="glossary.htm">Glossary</a>]
</DIV>

What is the reason for using MAP? Which site did you find that on? I'm
curious why that was suggested.

Joel

My apologies to bobby, webaim, jimthatcher<?>.

It is on the WAI site! At
http://www.w3.org/TR/WCAG10-HTML-TECHS/#group-bypass. Glad to discover
their examples use valid HTML!

Use of MAP provides structural information that a collection of links are
related. The benefit of using MAP is that in the future browsers can
include functions for people to directly navigate (move focus to) or skip
the links contained in a MAP element. Similar to using headers.

Use NAME instead of TITLE to label the collection of links.

According to the HTML 4.01 definition of MAP, it says:

"The MAP element may be used without an associated image for general
navigation mechanisms."
http://www.w3.org/TR/html401/struct/objects.html#edef-MAP

It also says that the NAME attribute is required, and TITLE is optional.

So, on the one hand their example is valid in using MAP to markup the
navigation bar. However, their example should have included a NAME
attribute to make it technically valid, even if an image is not associated
with the MAP.

I see Jon's point. The WAI example is still technically incorrect,
according to HTML 4.01. Use NAME with or instead of TITLE, or use a DIV
with TITLE.

would a screen reader read NAME? Is using both wrong, considering the
current technology? I need to hit SEND soon.

I love how there's no one answer. And outsiders think web accessibility is
clear cut!

NAME isn't meant to be read. It's for machine (browser) use, not for
human use.

I'm not sure if any browsers currently do anything special with <map>--
all I've heard is "future browsers." So i am not sure if doing it this
way will actually have any immediate accessibility effects in existing
screenreaders.

Does anyone know more about this, regarding how screenreaders use
<map>?

So do insiders.

I don't know of any AT or main stream browsers that currently provide any
additional functionality for access to the MAP element, either navigation
or reading the NAME or TITLE attribute. The main point of using MAP now is
to get it in common usage, so that developers will see a value in providing
the additional functionality. It is also important for people to encourage
developers to provide features that support access to the MAP element.

It is important to note that both TITLE and NAME should be defined to have
both a valid and more accessible document.

1. TITLE should be used to give a label to the purpose of the links
contained within the MAP block. For example "Navigation Bar", "Site Map"
or "My Favorite Links". Since this is the main mechanism to provided
additional information about an HTML element.

2. NAME seems to be similar to the NAME attribute in the INPUT and Anchor
element. It was originally designed to be a reference to an image or as an
internal link, which has been superceded by the id element, but it is used
by authors for backward compatibility. The NAME attribute has a number of
restrictions on the types of characters that it can contain[1], so TITLE
can be used to provide a more meaningful description, since it does not
have the same restrictions on characters as NAME. But NAME is required for
the document to be valid. So if there is not image, NAME could be defined
as "links" or something that is still slightly meaningful.
