如何在不刷新页面的情况下发布URL参数更改

var newUrl = window.location.pathname + '?param1=value1';
window.history.pushState({}, '', newUrl);

var searchParams = new URLSearchParams(window.location.search);
searchParams.set('param1', 'value1');
var newUrl = window.location.pathname + '?' + searchParams.toString();
window.history.pushState({}, '', newUrl);

var param1Value = 'value1';
var url = 'update-url.php?param1=' + param1Value;

var xhr = new XMLHttpRequest();
xhr.open('GET', url, true);
xhr.onreadystatechange = function() {
  if (xhr.readyState === 4 && xhr.status === 200) {
    // 处理服务器响应
    var response = xhr.responseText;
    // 更新页面的特定部分
    document.getElementById('result').innerHTML = response;
  }
};
xhr.send();
