Example
The ismap
attribute is set as follows:
<img src="giant-prawn.jpg" alt="The Giant Prawn at Ballina" ismap="ismap" />
Description
The ismap
attribute is rarely seen or used, and is used to indicate that the user’s
mouse actions over the image should be processed using a server-side image
map. When an area is clicked on with the mouse pointer (it cannot be
activated by keyboard controls), the co-ordinates are sent back to the
server in the form of a query string in the URI.
It is far more
common to see this handled client-side with the usemap
attribute.
