jquery - 响应式导航在响应模式下激活时搞砸了，然后再次调整大小

Question

我正在尝试构建一个响应式导航，但当我执行以下步骤时，它似乎会变得一团糟:1.调整导航到小于940px2.激活菜单3.然后我再次调整浏览器大小超过940px。4.现在菜单不再内联。一切都搞砸了。

这是我构建的代码。同样在代码笔上:https://codepen.io/rezasan/pen/YqjNMgHTML:

<header>
  <nav class="clearfix">
    <div class="pullmenu">
    </div>
    <ul class="clearfix">
      <li><a>About</a></li>
      <li><a>Services</a></li>
      <li><a>Products</a></li>
    </ul>
    <div class="logo">
      <a><img src="img/site_assets/logo_nav.png"></a>
    </div>
    <ul>
      <li><a>Media</a></li>
      <li><a>News</a></li>
      <li><a>Contact</a></li>
    </ul>
  </nav>
</header>

CSS:

    header {
      position: fixed;
      z-index: 1;
      width: 100%;
    }

    .logo {
      display: inline-block;
      vertical-align: top;
    }

    .logo img {
      width: 145px;
    }

    .pullmenu {
      display: none;
    }

    nav {
      height: 110px;
      width: 100%;
      background: #fff;
      letter-spacing: 0.2em;
      font-family: 'brandon-grotesque';
      font-weight: 500;
      position: relative;
      text-transform: uppercase;
    }

    nav ul {
      padding: 0;
      margin: 0 auto;
      display: inline-block;
    }

    nav li {
      display: inline;
      float: left;
    }

    nav a {
      display: inline-block;
      text-align: center;
      line-height: 110px;
      padding: 0px 20px;
      font-size: 8pt;
    }

    nav a:hover {
      text-decoration: underline;
    }

    @media screen and (max-width: 940px) {
      .logo {
        display: none;
      }
      nav {
        height: auto;
      }
      nav ul {
        width: 100%;
        display: none;
        height: auto;
      }
      nav li {
        width: 100%;
        float: none;
        position: relative;
      }
      nav li a {
        border-bottom: 1px solid #576979;
      }
      nav ul:last-child li:last-child a {
        border-bottom: none;
      }
      nav a {
        width: 100%;
        text-indent: 25px;
      }
      .pullmenu {
        display: block;
        background: gray;
        height: 110px;
        width: 100%;
        position: relative;
      }
    }

JQuery:

$(function() {
  var pull = $('.pullmenu');
  menu = $('nav ul');
  menuHeight = menu.height();
  $(pull).on('click', function(e) {
    e.preventDefault();
    menu.slideToggle();
  });
});

$(window).resize(function() {
  var w = $(window).width();
  if (w > 940 && menu.is(':hidden')) {
    menu.removeAttr('style');
  }
});

请参阅附件中的困惑对齐。

Answer 1

找到解决方案。这是由于 slideToggle 在调整回正常屏幕时将两个 ul 更改为显示为一个 block 。解决方案是创建一个将两个 ul 包装在一起的 div，并将该 div 用作要控制的目标。然后媒体查询将在浏览器宽度较短时隐藏该类。最后滑动切换 div。
