Javascript url查询字符串

const url = new URL('https://www.example.com/?name=John&age=25');
const searchParams = new URLSearchParams(url.search);
console.log(searchParams.get('name')); // 输出 "John"
console.log(searchParams.get('age')); // 输出 "25"

function getQueryParams() {
  const queryString = window.location.search.substring(1);
  const queryParams = queryString.split('&').map(param => param.split('='));
  const result = {};
  queryParams.forEach(([key, value]) => {
    result[decodeURIComponent(key)] = decodeURIComponent(value);
  });
  return result;
}

const params = getQueryParams();
console.log(params.name); // 输出 "John"
console println(params.age); // 输出 "25"
