单击 link 关闭导航

Question

我的导航会在用户单击“X”或按 esc 键时关闭，我希望它也能在用户单击 link 时关闭。导航是这样构造的；

<div class="top-bar">
        <button class="top-bar__nav-toggle hamburger" id="top-nav-toggle">
          <span></span>
          <span></span>
          <span></span>
        </button>
        <nav class="top-bar__nav collapsed" id="top-bar__nav">
          <ul class="top-bar__nav-list nav-ul">
            <li>
              <a class="navlink" href="#">Home</a>
            </li>
            <li>
              <a class="navlink" href="#Portfolio">Work</a>
            </li>
            <li>
              <a class="navlink" href="#About">About</a>
            </li>
            <li>
              <a class="navlink" href="#Contact">Contact</a>
            </li>
          </ul>
        </nav>
      </div>

样式如此；

  }

  .nav-ul li a {
    color: gray;
  }

  .top-bar__nav-toggle {
    display: inline-block;
  }

其功能来自这段代码；

(function () {
  if (document.querySelector("#top-nav-toggle")) {
    var navToggle = document.querySelector("#top-nav-toggle");

    function watchNavClose(e) {
      var topNav = document.querySelector(".top-bar");
      if (!e.path.includes(topNav)) {
        openCloseNav();
        document.documentElement.removeEventListener("click", watchNavClose);
      }
    }

    function openCloseNav() {
      var navToggle = document.querySelector("#top-nav-toggle");

      if (!navToggle.classList.contains("closed")) {
        navToggle.classList.add("closed");
        document.querySelector("#top-bar__nav").classList.remove("collapsed");
        document.querySelector("html").addEventListener("click", watchNavClose);
        document.body.style.overflowY = 'hidden';
      } else {
        document.querySelector("#top-bar__nav").classList.add("collapsed");
        document.documentElement.removeEventListener("click", watchNavClose);
        document.body.style.overflowY = "scroll";
        navToggle.classList.remove("closed");
        }
      }

      document.addEventListener('keydown', e => {
        if ( e.keyCode === 27 ) {
          document.documentElement.removeEventListener("click", watchNavClose);
          document.body.style.overflowY = "scroll";
          navToggle.classList.remove("closed");
          document.querySelector("#top-bar__nav").classList.add("collapsed");
        }
      })

      navToggle.addEventListener("click", openCloseNav);
  }
})

();

我主要是通过教程等进行构建，我已经尝试通过此处的类似问题来解决这个问题，但我对此并不陌生，无法弄清楚如何将其转换为我的代码。感谢任何帮助。

使用 querySelectorAll 和运行函数为 <a> 标签添加了单独的事件监听器，该函数在监听点击事件时关闭 nav

(function() {
  if (document.querySelector("#top-nav-toggle")) {
    var navToggle = document.querySelector("#top-nav-toggle");

    function watchNavClose(e) {
      var topNav = document.querySelector(".top-bar");
      if (!e.path.includes(topNav)) {
        openCloseNav();
        document.documentElement.removeEventListener("click", watchNavClose);
      }
    }

    function openCloseNav() {
      var navToggle = document.querySelector("#top-nav-toggle");

      if (!navToggle.classList.contains("closed")) {
        navToggle.classList.add("closed");
        document.querySelector("#top-bar__nav").classList.remove("collapsed");
        document.querySelector("html").addEventListener("click", watchNavClose);
        document.body.style.overflowY = 'hidden';
      } else {
        document.querySelector("#top-bar__nav").classList.add("collapsed");
        document.documentElement.removeEventListener("click", watchNavClose);
        document.body.style.overflowY = "scroll";
        navToggle.classList.remove("closed");
      }
    }

    document.addEventListener('keydown', e => {
      if (e.keyCode === 27) {
        document.documentElement.removeEventListener("click", watchNavClose);
        document.body.style.overflowY = "scroll";
        navToggle.classList.remove("closed");
        document.querySelector("#top-bar__nav").classList.add("collapsed");
      }
    })

    navToggle.addEventListener("click", openCloseNav);

    document.querySelectorAll(".navlink")[0].addEventListener("click", closeNav);
    document.querySelectorAll(".navlink")[1].addEventListener("click", closeNav);
    document.querySelectorAll(".navlink")[2].addEventListener("click", closeNav);
    document.querySelectorAll(".navlink")[3].addEventListener("click", closeNav);

    function closeNav() {
      var navToggle = document.querySelector("#top-nav-toggle");
      document.querySelector("#top-bar__nav").classList.add("collapsed");
      document.documentElement.removeEventListener("click", watchNavClose);
      document.body.style.overflowY = "scroll";
      navToggle.classList.remove("closed");
    }

  }
})
