Как скрыть меню при нажатии # ссылок (ссылок на одну и ту же страницу)?

Question

Может кто-нибудь, пожалуйста, скажите мне, как я могу заставить мое гамбургер-меню снова исчезнуть, если нажата какая-либо из #links (ссылка на ту же страницу) или кто-то щелкнет за пределами области меню? Я думаю, что мне нужно что-то добавить в мой код сценария JS, но я не могу найти правильную вещь, чтобы изменить или добавить. Я новичок, когда дело касается JavaScript.

const menuBtn = document.querySelector('.menu-btn');
let menuOpen = false;
menuBtn.addEventListener('click', () => {
  if (!menuOpen) {
    menuBtn.classList.add('open');
    document.getElementById("mymobilemenu").style.display = "block";
    menuOpen = true;
  } else {
    menuBtn.classList.remove('open');
    document.getElementById("mymobilemenu").style.display = "none";
    menuOpen = false;
  }
});

Answer 1

Попытка добавить это в ваш js скрипт:

const a = document.querySelectorAll('.a');
a.forEach(element => {
  element.addEventListener('click', () => {
    menuBtn.classList.remove('open');
    document.getElementById("mymobilemenu").style.display = "none";
    console.log("removed");
  })

});

Answer 2

Здравствуйте, вы можете сделать это, добавив foreach в <li>, поэтому каждый раз, когда кто-нибудь щелкает по нему, скрипт удаляет открытый класс в меню.

const menuBtn = document.querySelector('.menu-btn');
let menuOpen = false;
menuBtn.addEventListener('click', () => {
  if (!menuOpen) {
    menuBtn.classList.add('open');
    document.getElementById("mymobilemenu").style.display = "block";
    menuOpen = true;
  } else {
    menuBtn.classList.remove('open');
    document.getElementById("mymobilemenu").style.display = "none";
    menuOpen = false;
  }
});
let  menuli = document.querySelectorAll('#mymobilemenu li');
menuli.forEach((item, index) => {
 item.addEventListener('click', () => {
 menuBtn.classList.remove('open');
    document.getElementById("mymobilemenu").style.display = "none";
    menuOpen = false;
 
});

});

.menu-btn {
