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