js读取当前url

console.log(window.location.href); // 输出: https://www.example.com:8080/path/to/page.html?query=string#fragment
console.log(window.location.protocol); // 输出: https:
console.log(window.location.host); // 输出: www.example.com:8080
console.log(window.location.hostname); // 输出: www.example.com
console.log(window.location.port); // 输出: 8080
console.log(window.location.pathname); // 输出: /path/to/page.html
console.log(window.location.search); // 输出: ?query=string
console.log(window.location.hash); // 输出: #fragment

function getQueryStringParameters() {
  const query = window.location.search.substring(1); // 去除问号
  const params = new URLSearchParams(query);
  const result = {};
  for (const [key, value] of params.entries()) {
    result[key] = value;
  }
  return result;
}

// 使用示例
const queryParams = getQueryStringParameters();
console.log(queryParams); // 如果URL是"https://www.example.com?param1=value1&param2=value2"，则输出: { param1: "value1", param2: "value2" }
