You have the same problem as this asker. Your <img> tag needs a hash symbol: <img usemap="#menumap"> #8480298 – Litigant

Answer 1

I stumbled into this issue as well. It seems that Chrome will parse the img attribute usemap="mapName" without the # symbol. However, if you don't include the hash symbol '#', the map will not be associated with the image on FireFox and Internet Explorer.

Here is the correct way to do it:

<img src="images/header.jpg" id="hdr" name="hdr" usemap="#hdrMap" alt="alt string here" border="0">
    <map name="hdrMap" style="cursor:pointer;">
        <area shape="rect" coords="720,65,880,0" href="http://www.thisisthefirstlink.com" target="_blank" alt="first link alt">
        <area shape="rect" coords="882,65,1024,0" href="http://www.secondlink.com" target="_blank" alt="second link alt">
    </map>

Notice the usemap="#hrdMap" has a hash tag symbol and matches the name="hdrMap" attribute for the map tag. This can seem a little confusing because a lot of people associate the # symbol with referencing an id attribute.

Hope this helps

It's this problem, firefox is too damn standard. – Hokku

Answer 2

Another <map issue in Firefox and solution to it - make sure you're not using any anchor(<a>) elements inside <map>. If <map> has any <a> children Firefox will ignore whole <map> element.

It might be obvious not to use <a> elements because <area> has href attribute, but, for example, in Ember.js it was useful to me, to write code like that:

<map id='human-image-map' name='human-image' action='showTooltip'>
    <section class="front" title="Pokaż ćwiczenia">
      {{#link-to 'training.shoulders'}}
        <area alt="Barki" shape="poly" coords="39,74,37,75,35,77,33,78,32,76,32,73,32,71,32,68,33,65,33,63,34,61,36,58,37,56,38,54,40,53,42,52,44,51,46,51,48,51,51,50,55,49,57,48,59,47,61,47,59,50,58,52" />
        <area alt="Barki" shape="poly" coords="112,74,114,75,117,77,119,79,121,77,121,74,121,71,121,68,119,65,117,62,116,59,113,57,111,54,109,53,106,51,103,50,99,49,96,47,93,46,90,45,90,48,92,50,93,52,95,54,97,56,99,59,101,62,103,65,106,68" />
      {{/link-to}}
    </section>
</map>

I can't specify href attribute manually, it's considered best practice to leave this to link-to helper.

Solution to my specific Ember.js problem was just using another tag instead of <a>. So, adding tagName='span' to link-to helper solved my issue:

{{#link-to 'training.shoulders' tagName='span'}}
  <!-- ... -->
{{/link-to}}

Note: In Chrome <a> elements inside <map> just work fine.
