主菜单 JS 在 IE 和 Firefox 中不起作用（其他菜单起作用）

Question

当单击按钮时，我有从左侧滑动的主菜单和用户菜单。我还有一个向上滑动的搜索区域。一切都在 Chrome 中运行，但主菜单在 IE 和 Firefox 中不起作用，尽管其他人可以。

当我尝试在 IE 和 Firefox 中调试页面时，没有任何反应。

编辑：我在工作中再次尝试了它，它有时会起作用。

这是一段带有触发动作的选择器的 JS。

// MAIN MENU XS    
var mainMenu = document.getElementById( 'main-menu' ),
mainMenuTrigger = document.getElementById( 'main-menu-trigger' ),
body = document.body;

mainMenuTrigger.onclick = function() {
    alert('hlavní menu');
    ...
};

// USER MENU XS    
var userMenu = document.getElementById( 'user-menu' ),
userMenuTrigger = document.getElementById( 'user-menu-trigger' ),
body = document.body;

userMenuTrigger.onclick = function() {
   ...
};

这是 HTML 页面的一部分。
