Location: host - Web API 接口参考 编辑

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

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

anchor.href = "/wiki/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"
