我是网络开发新手，我正在使用不同的在线平台(YouTube、Udemy、StackSkills 等)自学。
现在我正努力专注于学习 HTML、CSS 和 JavaScript/JQuery 的基础知识。
我为一个自定义网站创建了这个汉堡菜单，我正在开发这个网站来帮助我学习，我想尝试让弹跳汉堡菜单在经过一定时间阈值后停止。
我尝试使用 JQuery 创建一个类，然后我可以使用 CSS 动画持续时间属性，但它完全停止了反弹。
这就是我使用 JQuery 和 CSS 尝试获得我想要的效果，完全停止弹跳动画效果，而不是让它在 5 秒后停止:
JQuery
function bounceDuration() {
document.querySelector('.hamburger-menu').classList.toggle('bounce-duration');
};
CSS
.hamburger-menu.bounce-duration {
animation-duration: 5s;
}
下面您将找到我当前的完整工作代码(HTML、CSS 和 JQuery)。正如您所看到的，汉堡菜单无限期地弹跳，我想以某种方式给它一个超时或某种持续时间。非常感谢任何对此的帮助。

document.querySelector(".hamburger-menu").addEventListener("click", () => {

将迭代计数设置为2(或任何其他数字)而不是无限:
function sidebarToggle() {
document.querySelector(".hamburger-menu").addEventListener("click", () => {
document.querySelector('.hamburger-menu').classList.toggle('bounce-stop');
document.querySelector(".container").classList.toggle("sidebar-toggle");
});
}
sidebarToggle()* {
margin: 0;
padding: 0;
outline: none;
box-sizing: border-box;
list-style: none;
text-decoration: none;
}
.hamburger-menu {
width: 3rem;
height: 3rem;
position: fixed;
top: 5rem;
right: 5rem;
z-index: 200;
display: flex;
flex-direction: column;
justify-content: space-evenly;
cursor: pointer;
transition: 0.7s;
}
.hamburger-menu.bounce-stop {
animation-name: none;
}
.line {
width: 100%;
height: 0.2rem;
background-color: #fff;
box-shadow: 0 0.1rem 0.2rem rgba(0, 0, 0, 0.2);
