HTML <object> usemap Attribute

The usemap attribute on an <object> tag binds the image resource to an image-map. This image-map partitions the image into clickable areas.

Example

#

A usemap attribute on an <object> element.
The image has a map with 3 clickable areas: screen, keyboard, and mouse.

Monitor Keyboard Mouse
<object data="/img/html/computer-map.png" alt="Computer" type="image/png" usemap="#computer"></object>

<map name="computer">
  <area shape="rect" coords="253,142,16,2" alt="Monitor" href="javascript:alert('Computer monitor was clicked');">
  <area shape="rect" coords="262,218,0,156" alt="Keyboard" href="javascript:alert('Computer keyboard was clicked');">
  <area shape="circle" coords="267,234,22" alt="Mouse" href="javascript:alert('Computer mouse was clicked');">
</map>

Note:  There is only limited browser support for usemap on the <object> element.
