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

<map name="planetmap">
