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";
