USEMAP Attribute | useMap Property

---

Sets or retrieves the URL, often with a bookmark extension (#name), to use as a client-side image map.

Syntax

HTML	<IMG USEMAP = sURL ... >
Scripting	img.useMap [ = sURL ]

Possible Values

sURL	String that specifies the URL of the image map.

The property is read/write with no default value.

Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. For more information, see Dynamic Properties.

Remarks

The useMap property identifies the image as a client-side image map by associating a MAP object with the image. This MAP object contains AREA objects that define regions within the image. The user can click these regions to navigate to a designated URL.

You can dynamically assign the maps to the image through the useMap property.

Example

This example specifies map1 as the image map underlying image.gif. The map can be changed to another map, map2, by clicking the button.

<MAP NAME="map1">
<AREA NAME="area1" COORDS="0,0,40,40" HREF="doc1.htm"
