Value

A string containing the hash # symbol followed by the name of the <map> element which defines the image map to apply to the image.

Examples

Using useMap

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" />
</map>

Given the image map named mainmenu-map, you can dynamically construct images that reference the image map as follows:

const image = new Image();
image.src = "menu-box.png";
image.alt = "";
image.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.
