HTMLAnchorElement: 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 HTMLAnchorElement
interface is a string containing the port number of the URL, or the empty string if the port is the default for the protocol.
Note:
If the HTMLAnchorElement
object refers to a URL that doesn't contain an explicit port number (e.g., https://localhost
) or contains a port number that's the default port number corresponding to the protocol part of the URL (e.g., https://localhost:443
), then the port
property will be the empty string: ''
.
Value
A string.
Examples
Getting the port from an anchor link
// An <a id="myAnchor" href="https://developer.mozilla.org:443/en-US/docs/HTMLAnchorElement"> element is in the document
const anchor = document.getElementByID("myAnchor");
anchor.port; // returns ''
// Another <a id="myAnchor" href="https://developer.mozilla.org:8888/en-US/docs/HTMLAnchorElement"> element is in the document
const anchor = document.getElementByID("myAnchor");
anchor.port; // Returns:'8888'
