Dynamic HTML: The Definitive Reference

Name

USEMAP — NN all IE all HTML 3.2

Synopsis

USEMAP=”mapURL"

Optional

You can define a client-side image map with the help of the MAP and AREA elements. The MAP element is a named container for one or more AREA element. Each AREA element sets a “hot” area on an image and assigns a link destination (and other settings) for a response to the user clicking in that region. The purpose of the USEMAP attribute is to establish a connection between the IMG element and a named MAP element in the same document. In some respects, the MAP element’s name is treated like an anchor in that the “address” of the MAP element is the element’s name preceded by a # symbol.

Example

<IMG SRC="navbar.gif" USEMAP="#navigation" HEIGHT=90 WIDTH=120>

Value

A URL to the MAP element in the same document (a hash symbol plus the MAP name).

Default

None.
