js如何给地址栏添加参数

// 假设当前URL是 http://example.com
window.location.href += '?param1=value1&param2=value2';

// 获取当前URL
let currentUrl = new URL(window.location.href);

// 添加参数
currentUrl.searchParams.append('param1', 'value1');
currentUrl.searchParams.append('param2', 'value2');

// 更新地址栏
window.location.href = currentUrl.toString();

// 获取当前URL
let currentUrl = window.location.href;

// 检查是否已经有参数
let separator = currentUrl.includes('?') ? '&' : '?';

// 拼接新参数
currentUrl += separator + 'param1=value1&param2=value2';

// 更新地址栏
window.location.href = currentUrl;

let encodedValue = encodeURIComponent('value with spaces');
