The host
property of the URL
interface is a string containing the host, which is the hostname
, and then, if the port of the URL is nonempty, a ":"
, followed by the port
of the URL. If the URL does not have a hostname
, this property contains an empty string, ""
.
This property can be set to change both the hostname and the port of the URL. If the URL's scheme is not hierarchical (which the URL standard calls "special schemes"), then it has no concept of a host and setting this property has no effect.
Note: If the given value for the host
setter lacks a port
, the URL's port
will not change. This can be unexpected as the host
getter does return a URL-port string, so one might have assumed the setter to always "reset" both.
A string.
Exampleslet url = new URL("https://developer.mozilla.org/en-US/docs/Web/API/URL/host");
console.log(url.host); // "developer.mozilla.org"
url = new URL("https://developer.mozilla.org:443/en-US/docs/Web/API/URL/host");
console.log(url.host); // "developer.mozilla.org"
// The port number is not included because 443 is the scheme's default port
url = new URL("https://developer.mozilla.org:4097/en-US/docs/Web/API/URL/host");
console.log(url.host); // "developer.mozilla.org:4097"
