Location: hostname 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 hostname
property of the Location
interface is a string containing either the domain name or IP address of the location URL. If the URL does not have a hostname, this property contains an empty string, ""
. IPv4 and IPv6 addresses are normalized, such as stripping leading zeros, and domain names are converted to IDN.
See URL.hostname
for more information.
Value
A string.
Examples
js
console.log(window.location.hostname);
// developer.mozilla.org
const anchor = document.createElement("a");
anchor.href = "https://developer.mozilla.org:4097/";
console.log(anchor.hostname === "developer.mozilla.org");
// The port number is not included in hostname
