HTMLAreaElement: port property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The port
property of the HTMLAreaElement
interface is a string containing the port number of the <area>
element's href
. If the port is the default for the protocol (80
for ws:
and http:
, 443
for wss:
and https:
, and 21
for ftp:
), this property contains an empty string, ""
.
This property can be set to change the port of the URL. If the URL has no host
or its scheme is file:
, then setting this property has no effect. It also silently ignores invalid port numbers.
See URL.port
for more information.
Value
A string.
Examples
Getting the port from an area link
// An <area id="myArea" href="https://developer.mozilla.org:443/en-US/docs/HTMLAreaElement"> element is in the document
