Question

下午好

我正在使用一个菜单，该菜单在我的站点上带有铃声，但是此菜单在站点加载时打开。我试图用javascript切换代码，但没有成功。菜单仅在单击按钮后才能打开。

我将所有菜单代码（CSS）留在此处，以便更轻松地查看问题。

（对不起我的英语不好）预先感谢。

toggle = document.querySelectorAll(".toggle")[0];
nav = document.querySelectorAll("nav")[0];
toggle_open_text = '&#9776;';
toggle_close_text = '&#10006;';

nav.classList.toggle('open');

toggle.addEventListener('click', function() {
	nav.classList.toggle('open');
	
  if (nav.classList.contains('open')) {
    toggle.innerHTML = toggle_close_text;
  } else {
    toggle.innerHTML = toggle_open_text;
  }
}, false);

setTimeout(function(){
	nav.classList.toggle('open');	
}, 800);

Answer 1

只需将其删除：

setTimeout(function(){
    nav.classList.toggle('open');   
}, 800);

Answer 2

问题是您要在类.open中添加setTimeout。

删除setTimeout，一切都会好起来
