An Area object is created by an <AREA> tag within a client-side image map:
<MAP NAME="map_name"> <AREA SHAPE="area_shape" COORDS=coordinates HREF="url" the destination of the link [ TARGET="window_name" ] where the new document should be displayed [ onClick="handler" ] invoked when area is clicked [ onMouseOver="handler" ] invoked when mouse is over area [ onMouseOut="handler" ] invoked when mouse leaves area > ... </MAP>
There are only two differences between hypertext links created with the <AREA> tag and those created with the <A> tag. The first is that links in image maps are not recognized by Navigator 2.0 and Internet Explorer--those browsers only recognize links created with the <A> tag. The second difference is simply a bug: the onClick() event handler of the <AREA> tag doesn't work on Windows platforms in Navigator 3.0.
See Link for a listing and description of the properties and event handlers of hypertext links.
