Question

问：有没有办法让子弹分隔每个导航项目？我的用户有大屏幕，所以我不关心崩溃菜单会发生什么。运行此代码段时，请确保使用整页。

如果有帮助，我也会使用fontawesome。如果你想使用fa-ul类。

只需添加：

const menu = (function Menu() {
  // this state is privately scoped
  const courses = {
    appetizers: [],
    main: [],
    dessert: []
  };

  // these functions are privately scoped, unless revealed (see below)
  function addDish(course, name, price) {
    courses[course].push({ name, price });
  }

  function getDishesByCourse(course) {
    return courses[course];
  }

  // this is what you are revealing to the outside
  return { addDish, getDishesByCourse };
})();


menu.addDish('appetizers', 'pepperoni', 5.43);
console.log(menu.getDishesByCourse('appetizers'));
