Javascript ne fonctionne pas pour certaines versions iOS d’iPhone

J’ai du code javascript sur ma page Web, cela fonctionne pour le bureau, Android,
Cependant, cela ne fonctionne pas pour certains iPhones, chaque partie de mon code, événements d’entrée, événement de clic

Fonctionne pour ces modèles et versions d’iPhone :

1. Iphone 13 safari version 16.6

2. Iphone 12 safari version 16.6

3. Iphone 13 safari version 16.5.1

4. Iphone 11 safari version 16.5

Mais mon code ne fonctionne pas pour ce type d’iPhone :

1. Iphone 11 safari version 16.1

2. Iphone 11 safari version 16.3.1

3. Iphone XS Max safari version 16.5.1

4. Safari iPhone Xr version 16.5.1

5. Safari iPhone XR version 16.3.1

**Voici mon code :**

document.addEventListener("DOMContentLoaded", function() {
    const header = document.querySelector(".header");
    const langSelect = document.querySelector("#lang_select");
    const langList = document.querySelector(".lang_list");

    header.addEventListener("click", function(event) {
      langList.style.display = langList.style.display === "none" ? "block" : "none";
      event.stopPropagation();
    });

    document.addEventListener("click", function(event) {
      if (!langSelect.contains(event.target)) {
        langList.style.display = "none";
      }
    });

    const fieldInputs = document.querySelectorAll(".field input");

fieldInputs.forEach(function(input) {
  input.addEventListener("focus", function() {
    this.parentElement.classList.add("active");
  });

  input.addEventListener("blur", function() {
    if (this.value === "") {
      this.parentElement.classList.remove("active");
    }
  });
});

let isFirstOpen = false;
  const firstBtn = document.querySelector("#firstBtn");
  const firstDrop = document.querySelector("#firstDrop");

  firstBtn.addEventListener("click", function(event) {
    isFirstOpen = !isFirstOpen;

    if (isFirstOpen) {
      firstDrop.style.display = "block";
    } else {
      firstDrop.style.display = "none";
    }

    event.stopPropagation();
  });

  document.addEventListener("click", function(event) {
  if (
    !event.target.closest("#firstBtn") &&
    !event.target.closest("#firstDrop")
  ) {
    const firstDropElement = document.querySelector("#firstDrop");
    if (firstDropElement.style.display !== "none") {
      firstDropElement.style.display = "none";
      isFirstOpen = false;
    }
  }
});

Ce que j’ai essayé :

– Je vérifiais si j’avais des erreurs de syntaxe mais je n’en ai pas
– Je pensais utiliser des fonctions avancées et j’ai refait mon code avec bubble mais ça n’a pas aidé
– Je pensais qu’il y avait un problème avec l’événement click, j’ai donc ajouté un événement touch mais cela n’a pas aidé
– J’ai essayé d’utiliser la simulation sur Mac, mais le code fonctionnait parfaitement
– J’ai utilisé la simulation dans la pile du navigateur et voilà mes problèmes
