HTMLAreaElement: port property - Web APIs | MDN (original) (raw)
Baseline
Widely available
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
