Bulma导航栏汉堡菜单不展开。

我复制了Bulma的基础模板和基础导航栏。但是，当我点击汉堡菜单时，什么也没有发生:(。我漏掉了什么吗？你可以在我的jsfiddle中尝试一下：

“Bulma套件不带有任何JavaScript。这里提供一个示例实现，使用纯Javascript在导航栏汉堡包按钮和目标导航菜单之间切换is-active类。”

添加一些js：

document.addEventListener('DOMContentLoaded', () => {

  // Get all "navbar-burger" elements
  const $navbarBurgers = Array.prototype.slice.call(document.querySelectorAll('.navbar-burger'), 0);

  // Check if there are any navbar burgers
  if ($navbarBurgers.length > 0) {

    // Add a click event on each of them
    $navbarBurgers.forEach( el => {
      el.addEventListener('click', () => {

        // Get the target from the "data-target" attribute
        const target = el.dataset.target;
        const $target = document.getElementById(target);

        // Toggle the "is-active" class on both the "navbar-burger" and the "navbar-menu"
        el.classList.toggle('is-active');
        $target.classList.toggle('is-active');

      });
    });
  }

});
