How to get the value of the usemap attribute in JavaScript?

To get the value of the usemap attribute of a link in JavaScript, use the useMap property. The usemap attribute is used to tell that the document is html (text/html) or css (text/css), etc.

Client-side image maps are enabled by the usemap attribute for the <img /> tag and defined by special <map> and <area> extension tags. The image that is going to form the map is inserted into the page using the <img /> element as normal, except that it carries an extra attribute called usemap.

Example

You can try to run the following code to get the value of the usemap attribute of a link −
