The useMap property on the HTMLImageElement interface reflects the value of the HTML usemap attribute, which is a string providing the name of the client-side image map to apply to the image.


htmlImageElement.useMap = imageMapAnchor;
let imageMapAnchor = htmlImageElement.useMap;


A USVString providing the page-local URL (that is, a URL that begins with the hash or pound symbol, "#") of the <map> element which defines the image map to apply to the image.

You can learn more about client-side image maps in our learning article Add a hitmap on top of an image.

Usage notes

The string value of useMap must be a valid anchor for a <map> element. In other words, this string should be the value of the appropriate <map>'s name attribute with a pound or hash symbol prepended to it.

Consider a <map> that looks like this:

<map name="mainmenu-map">
  <area shape="circle" coords="25, 25, 75" href="/index.html" alt="Return to home page">
  <area shape="rect" coords="25, 25, 100, 150" href="/index.html" alt="Shop">

Given the image map named mainmenu-map, the image which uses it should look something like the following:

<img src="menubox.png" usemap="#mainmenu-map">

For additional examples (including interactive ones), see the articles about the <map> and <area> elements, as well as the guide to using image maps.
