在《Sample XHTML 1.0 document》里看到图像热区也可以跟链接关联到一起，即点热区和点链接是一样的地址。看下具体的玩法。
正常的玩法：
=========================HTML===================================
<img src="dot.png" alt="image" usemap="#map" height="40″ width="40″ />
<div> <map xml:lang="en" dir="ltr" id="map" class="map" title="map" name="map" lang="en"> <area href="#grouping.heading" id="area" class="area" title="area" xml:lang="en" dir="ltr" shape="rect" coords="0,0,19,19″ alt="Grouping elements: div and span" tabindex="5″ lang="en" /> <area href="#" shape="rect" coords="20,0,39,20″ alt="Headings: h1, h2, h3, h4, h5, h6″ tabindex="6″ /> <area href="#" shape="rect" coords="0,20,20,39″ alt="Address: address" tabindex="7″ /> <area shape="rect" coords="20,20,39,39″ nohref="nohref" /> </map></div>
===============================================================
关联链接：
=========================HTML===================================
<img src="dot.png" alt="image" usemap="#map2″ height="40″ width="40″ />
<div> <map xml:lang="en" dir="ltr" id="map2″ class="map" title="map" name="map2″ lang="en">
<ul>
<li><a href="#" shape="rect" coords="0,0,19,19″>Grouping elements: div and span</a></li>
<li><a href="#" shape="rect" coords="20,0,39,20″>Headings: h1, h2, h3, h4, h5, h6</a></li>
<li><a href="#" shape="rect" coords="0,20,20,39″>Address: address</a></li>
</ul>
</map></div>
===============================================================
