Question

Okey所以当我试图制作下拉式响应导航栏时，它只是不起作用，所以如果有人可以帮助我，这将是很好的:)）

有关我的问题的更多信息。

当我按下此按钮时，菜单应该打开 picture of navbar

通常我改变的时候标题导航ul高度为0它关闭它但当我将其更改为自动;它打开菜单，但它不会关闭它，所以我试图制作脚本，当你点击该图片时，它会将其转为自动;但我似乎没有工作。所以我的问题是我无法打开它或关闭它。

fa-bars是来自awesomefont的图片，只是为了清楚说明。

这里有一些代码。

$(document).ready(function() {
  $(".fa-bars").on("click", function() {
    $("header nav ul").toggleClass("open");
  });
});

/* MOBILES */

@media screen and (max-width: 480px){
  #logo {
    width: 80px;
    margin-left: 30px;
    margin-top: 15px;
  }
  header nav {
    margin: 0;
    float: none;
  }
  .fa-bars {
    font-size: 24px;
    display: inline-block;
    width: 100%;
    cursor: pointer;
    text-align: right;
    float: right;
    margin: 13px 35px 0 0;
  }
  .fa-bars:hover {
    opacity: 0.5;
  }
  header nav ul {
    height: 0;
    overflow: hidden;
    margin: 0;
    padding: 0;
    width: 100%;
  }
  header nav ul.open {
    height: auto;
  }
  header nav ul li {
    width: 100%;
    padding: 5px 0;
    margin: 0;
    font-size: 17px;
    border-top: 1px solid #dddddd;
  }

  header nav ul li:hover {
    background-color: #eeeeee;
  }

您尚未加载脚本文件。

尝试使用我在此处进行的修正。

$(document).ready(function() {
 $('.fa-bars').on('click', function() {
  $('header nav ul').toggleClass('open');
 });
});

@media screen and (max-width: 480px) {
  

#logo {
    width: 80px;
    margin-left: 30px;
    margin-top: 15px;
  }
}

header nav {
  margin: 0;
  float: none;
}

.fa-bars {
  font-size: 24px;
  display: inline-block;
  width: 100%;
  cursor: pointer;
  text-align: right;
  float: right;
  margin: 13px 35px 0 0;
}

.fa-bars:hover {
  opacity: 0.5;
}

header nav ul {
  height: 0;
  overflow: hidden;
  margin: 0;
  padding: 0;
  width: 100%;
}

header nav ul.open {
  height: auto;
}

header nav ul li {
  width: 100%;
  padding: 5px 0;
  margin: 0;
  font-size: 17px;
  border-top: 1px solid #dddddd;
}

header nav ul li:hover {
  background-color: #eeeeee;
}
