Image useMap Property

Image Object

Definition and Usage

The useMap property sets or returns the value of the usemap attribute of an image.

The usemap attribute specifies an image as a client-side image-map (an image-map is an image with clickable areas).

The usemap attribute is associated with a map element's name attribute, and creates a relationship between the image and the map.

Syntax

imageObject.useMap=value

The useMap property can have the following value:

Value	Description
#mapname	A hash character ("#") plus the name of the map element to use

Browser Support

The useMap property is supported in all major browsers.

Example

Return the value of the usemap attribute of a client-side image-map:

<html>
<body>

<img id="planets" src="planets.gif"
width="145" height="126"
usemap="#planetmap">

<map name="planetmap">
<area id="venus" shape="circle"
coords="124,58,8"
alt="The planet Venus"
href="venus.htm">
</map>

<p>The value of the usemap attribute is:
<script>
document.write(document.getElementById("planets").useMap);
</script>
</p>

</body>
</html>
