Area host Property

Area Object

Definition and Usage

The host property sets or returns the hostname:port part of the href attribute value.

Syntax

areaObject.host=hostname:port

Browser Support

The host property is supported in all major browsers.

Tips and Notes

Note: If the port part is not specified in the URL, or is 80 (which is default), some browsers will not display the port part.

Example

Return the hostname:port for the "Venus" area in the image-map:

<html>
<body>

<img src="planets.gif"
width="145" height="126"
usemap="#planetmap">

<map name="planetmap">
<area id="venus" shape="circle"
coords="124,58,8"
alt="Venus"
href="venus.htm">
</map>

<p>The hostname:port for the "Venus" area is:
<script>
document.write(document.getElementById('venus').host);
</script>
</p>

</body>
</html>

The output of the code above will be:

The hostname:port for the "Venus" area is: www.w3schools.com:80
