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";
