如何將類名（列表）替換為 Javascript？我有這個(gè)代碼：document.addEventListener("DOMContentLoaded", (e) => {    const url = window.location;    let urlReq = url.href;    if(urlReq.includes('/home')){        document.getElementById('default-sidenav-menu').className.replace('sidenav-main nav-expanded nav-lock nav-collapsible  sidenav-active-rounded  sidenav-dark', 'sidenav-main nav-collapsed nav-collapsible  sidenav-active-rounded  sidenav-dark');        console.log(document.getElementById('default-sidenav-menu').className);    }});這是我的html：<aside class="sidenav-main nav-expanded nav-lock nav-collapsible  sidenav-active-rounded  sidenav-dark" id="default-sidenav-menu">    <div class="brand-sidebar">    ...</aside>但我仍然得到默認(rèn)的 className:sidenav-main nav-expanded nav-lock nav-collapsible  sidenav-active-rounded  sidenav-dark當(dāng)我的頁(yè)面加載時(shí)。我犯了什么錯(cuò)誤？
