Location: host

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.

Location 接口的 host 属性是包含了主机的一段 USVString，其中包含：主机名，如果 URL 的端口号是非空的，还会跟上一个 ':' ，最后是 URL 的端口号。

Syntax

string = object.host;
object.host = string;

Examples

js
var anchor = document.createElement("a");

anchor.href = "https://developer.mozilla.org/en-US/Location.host";
anchor.host == "developer.mozilla.org";

anchor.href = "https://developer.mozilla.org:443/en-US/Location.host";
anchor.host == "developer.mozilla.org";
// 这里 host 中没有包含端口号，因为 443 是 https 协议的默认端口号

anchor.href = "https://developer.mozilla.org:4097/en-US/Location.host";
anchor.host == "developer.mozilla.org:4097";
