单击页面链接一次时，导航/汉堡图标消失

Question

我正在设计一个单页滚动网站。当我在屏幕宽度小于 780 像素（出现汉堡图标时）的导航栏中单击页面链接时，汉堡图标消失。除非我刷新页面，否则我无法取回它。单击页面链接一次后，导航栏也会以全屏宽度消失。我想始终保持汉堡图标和顶部导航可见。我用来折叠以 780px 显示的全屏菜单的 javascript 导致了这个问题，但我需要它，否则单击链接时菜单不会消失。感谢任何可以提供帮助的人！

$(document).ready(function() {
    $('a').click(function() {
        $('#menu').slideToggle();
    });
});

@media screen and (max-width: 780px) {

    nav {
        width: 100%;
        margin: 0;
        padding: 0;
        position: relative;
        left: 0;
        display: block;
        opacity: 1.0 !important;
        filter: alpha(opacity=100); /* For IE8 and earlier */
    }

    nav ul {
        width: 100%;
        margin: 0 auto;
        padding: 0;
        display: none;
        float: none;
    }

    nav ul li {
        font-size: 1.3em;
        font-weight: normal;
        line-height: 40px;
        width: 100% !important;
        margin: 0;
        padding: 0;
    }

    nav ul li:nth-of-type(1) { margin-top: 20%; }

    nav ul li:hover { background: #565758; }
    
    nav ul li a {
        color: white !important;
        font-family: "Lato", sans-serif;
        border-bottom: none !important;
        display: inline-block;
    }

    nav ul li a.active-link {
        color: white !important;
        font-size: 1.3em;
    }

    nav ul li a:hover {
        color: white;
        width: 100%;
    }
        
    /*Display 'show menu' link*/
    .show-menu {
        margin: 0 !important;
        padding: 1em !important;
        text-align: right;
        display: block;
        float: right;
    }

    /*Show menu when invisible checkbox is checked*/
    input[type=checkbox]:checked ~ #menu { background-color: #747475 !important; display: block; height: 100vh; }
}​

    <nav>
        <label for="show-menu" class="show-menu"><img src="hamburger.png" alt="Hamburger Menu Icon" style="width: 15%;"></label>
        <input type="checkbox" id="show-menu" role="button">

您还需要将切换按钮添加到复选框。它是一个 jQuery 函数，使用特定的动画和样式。

$('#show-menu').click(function() {
    $('#menu').slideToggle();
});

我添加了一个工作示例。为了更好的设计，我没有在这里使用切换开关。现在菜单也可以通过单击复选框来切换:-)

$(document).ready(function() {
    $('a').click(function() {
        $('#menu').slideToggle();
    });
  $('#show-menu').change(function() {
      if(this.checked)
        $('#menu').slideDown();
      else
        $('#menu').slideUp();
  });
});

@media screen and (max-width: 780px) {

    nav {
        width: 100%;
        margin: 0;
        padding: 0;
        position: relative;
        left: 0;
        display: block;
        opacity: 1.0 !important;
        filter: alpha(opacity=100); /* For IE8 and earlier */
    }

    nav ul {
        width: 100%;
        margin: 0 auto;
        padding: 0;
        display: none;
        float: none;
    }

    nav ul li {
        font-size: 1.3em;
        font-weight: normal;
        line-height: 40px;
        width: 100% !important;
        margin: 0;
        padding: 0;
    }

    nav ul li:nth-of-type(1) { margin-top: 20%; }

    nav ul li:hover { background: #565758; }
    
    nav ul li a {
        color: white !important;
        font-family: "Lato", sans-serif;
        border-bottom: none !important;
        display: inline-block;
    }

    nav ul li a.active-link {
        color: white !important;
        font-size: 1.3em;
    }

    nav ul li a:hover {
        color: white;
        width: 100%;
    }
        
    /*Display 'show menu' link*/
    .show-menu {
        margin: 0 !important;
        padding: 1em !important;
        text-align: right;
        display: block;
        float: right;
    }

    /*Show menu when invisible checkbox is checked*/
    input[type=checkbox]:checked ~ #menu { background-color: #747475 !important; display: block; height: 100vh; }
}​
