在 Web 開發方面，我對 Javascript 還很陌生。我正在使用引導程序來構建導航欄。我的導航欄在展開時看起來不錯，但在折疊時，設計就亂七八糟了。我的代碼看起來像這樣 <!DOCTYPE html><html><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>E-Commerce</title> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous"><link rel="stylesheet" href="css/main.css"></head><body> <nav class="navbar navbar-expand-lg navbar-dark bg-dark"> <a class="navbar-brand" href="">E-Commerce</a> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse" id="navbarSupportedContent"> <ul class="navbar-nav mr-auto"> <li class="nav-item active"> <a class="nav-link" href="">Home <span class="sr-only">(current)</span></a> </li> </ul> <div class='form-inline my-2 my-lg-0'> <a href="" class="btn btn-warning change-style" style="margin-right:5px;">SignUp</a> <a href="" class="btn btn-warning change-style">Login</a> <a href=""><img id="cart-icon" src="" alt="cart"></a> <p id="cart-total">0</p> </div> </div> </nav></body></html>當導航欄折疊我的登錄時，注冊按鈕出現在折疊的導航欄菜單內的一行中，但我希望它們顯示為單獨的導航欄鏈接，就像主頁鏈接一樣，并松開 btn 類。我試過編寫以下js腳本，但沒有產生預期的效果。var toggleButton = document.getElementsByClassName("navbar-toggler");toggleButton[0].addEventListener("click", () => { var buttons = document.getElementsByClassName("change-style"); for (i = 0; i < buttons.length; i++) { buttons[i].className = "nav-link"; }});有人可以幫忙嗎？
導航欄折疊時如何更改類？
