// 获取协议（如http:或https:）
var protocol = window.location.protocol;

// 获取主机名（如www.example.com）
var hostname = window.location.hostname;

// 获取端口号（如8080）
var port = window.location.port;

// 获取路径（如/path/to/page.html）
var pathname = window.location.pathname;

// 获取查询字符串（如?key=value）
var search = window.location.search;

// 获取哈希值（如#section）
var hash = window.location.hash;

console.log("Full URL: " + fullUrl);
console.log("Protocol: " + protocol);
console.log("Hostname: " + hostname);
console.log("Port: " + port);
console.log("Pathname: " + pathname);
