JavaScript如何在不重新加载页面的情况下修改URL

// 当前URL: http://example.com/
const newState = {}; // 新的状态对象
const title = 'New Page Title'; // 新的页面标题
const url = '/new-page'; // 新的URL路径

window.history.pushState(newState, title, url);

// 修改后的URL: http://example.com/new-page

// 当前URL: http://example.com/
const newState = {}; // 新的状态对象
const title = 'Updated Page Title'; // 更新的页面标题
const url = '/updated-page'; // 更新的URL路径

window.history.replaceState(newState, title, url);

// 修改后的URL: http://example.com/updated-page

// 当前URL: http://example.com/
const hash = '#section1';

window.location.hash = hash;

// 修改后的URL: http://example.com/#section1

window.addEventListener('popstate', (event) => {
    console.log('URL changed:', window.location.href);
    // 根据新的URL更新页面内容
});
