Lottie Hamburger 菜单在响应式页面中的使用

Question

单击 link 之一时，菜单消失。

同时，当点击 link 时，lottie 动画返回到汉堡图标状态（它保持在 X 状态）这是 link https://codepen.io/OralYildiz/pen/abwvazw

Answer 1

以下工作：

用所有 3 个菜单的数组定义一个变量-link:

// querySelectorAll gets you all 3 menu-links
const menuLink = document.querySelectorAll(".nav__link");

定义一个函数()关闭菜单并向后播放乐透播放器:

function closeMenu() {
  // pageHeader.classList.toggle(menuOpenedClass); // would also work;
  pageHeader.classList.remove("menu-open");

  // play lottie player segment backwards
  player.getLottie().playSegments([45, 0], true);
}

添加事件侦听器到所有 3 个菜单-links:

menuLink.forEach(function (element) {
  element.addEventListener("click", function () {
    closeMenu();
  })
});
