单击后关闭下拉菜单

Question

我为我的网页创建了一个汉堡包下拉菜单。 但是我发现在点击其中一个链接后，下拉菜单没有关闭。 我确实试图在网上找到解决方案，但没有一个能奏效。 请帮忙！

 .header { margin-top: 60px; /* only to clear the 'Full page' button in the snippet */ background-color: #000; box-shadow: 1px 1px 4px 0 rgba(0, 0, 0, .1); width: 100%; z-index: 3; } .header ul { margin: 0; padding: 0; list-style: none; overflow: hidden; } .header li a { display: block; padding: 20px 20px; /*border-right: 1px solid #f4f4f4;*/ text-decoration: none; } #rmb_call { display: block; padding: 20px 20px; /*border-right: 1px solid #f4f4f4;*/ text-decoration: none; } #rmb_call:hover { background-color: gray; } .header li a:hover { background-color: gray; } .header .logo { display: block; float: left; font-size: 2em; padding: 10px 20px; text-decoration: none; } .header .menu { clear: both; max-height: 0; transition: max-height .2s ease-out; } .header .menu-icon { cursor: pointer; display: inline-block; float: right; padding: 28px 20px; position: relative; user-select: none; } .header .menu-icon .navicon { background: #fff; display: block; height: 2px; position: relative; transition: background .2s ease-out; width: 18px; } .header .menu-icon .navicon:before, .header .menu-icon .navicon:after { background: #fff; content: ''; display: block; height: 100%; position: absolute; transition: all .2s ease-out; width: 100%; } .header .menu-icon .navicon:before { top: 5px; } .header .menu-icon .navicon:after { top: -5px; } .header .menu-btn { display: none; } .header .menu-btn:checked ~ .menu { max-height: 410px; } .header .menu-btn:checked ~ .menu-icon .navicon { background: transparent; } .header .menu-btn:checked ~ .menu-icon .navicon:before { transform: rotate(-45deg); } .header .menu-btn:checked ~ .menu-icon .navicon:after { transform: rotate(45deg); } .header .menu-btn:checked ~ .menu-icon:not(.steps) .navicon:before, .header .menu-btn:checked ~ .menu-icon:not(.steps) .navicon:after { top: 0; } @media (min-width: 994px) { .header li { float: left; } .header li a { padding: 20px 30px; } #rmb_call { float: left; } #rmb_call:hover { padding: 20px 30px; } .header .menu { clear: none; float: right; max-height: none; } .header .menu-icon { display: none; } }

因为你用JavaScript和jQuery标记了这个问题....

您可以通过在单击菜单项时触发关闭按钮上的单击事件来执行此操作：

$('.menu').on('click', 'li', function(){
    $('#menu-btn').trigger('click');
});

 $('.menu').on('click', 'li', function(){ $('#menu-btn').trigger('click'); }); 

 .header { margin-top: 60px; /* only to clear the 'Full page' button in the snippet */ background-color: #000; box-shadow: 1px 1px 4px 0 rgba(0, 0, 0, .1); width: 100%; z-index: 3; } .header ul { margin: 0; padding: 0; list-style: none; overflow: hidden; } .header li a { display: block; padding: 20px 20px; /*border-right: 1px solid #f4f4f4;*/ text-decoration: none; } #rmb_call { display: block; padding: 20px 20px; /*border-right: 1px solid #f4f4f4;*/ text-decoration: none; } #rmb_call:hover { background-color: gray; } .header li a:hover { background-color: gray; } .header .logo { display: block; float: left; font-size: 2em; padding: 10px 20px; text-decoration: none; } .header .menu { clear: both; max-height: 0; transition: max-height .2s ease-out; } .header .menu-icon { cursor: pointer; display: inline-block; float: right; padding: 28px 20px; position: relative; user-select: none; } .header .menu-icon .navicon { background: #fff; display: block; height: 2px; position: relative; transition: background .2s ease-out; width: 18px; } .header .menu-icon .navicon:before, .header .menu-icon .navicon:after { background: #fff; content: ''; display: block; height: 100%; position: absolute; transition: all .2s ease-out; width: 100%; } .header .menu-icon .navicon:before { top: 5px; } .header .menu-icon .navicon:after { top: -5px; } .header .menu-btn { display: none; } .header .menu-btn:checked ~ .menu { max-height: 410px; } .header .menu-btn:checked ~ .menu-icon .navicon { background: transparent; } .header .menu-btn:checked ~ .menu-icon .navicon:before { transform: rotate(-45deg); } .header .menu-btn:checked ~ .menu-icon .navicon:after { transform: rotate(45deg); } .header .menu-btn:checked ~ .menu-icon:not(.steps) .navicon:before, .header .menu-btn:checked ~ .menu-icon:not(.steps) .navicon:after { top: 0; } @media (min-width: 994px) { .header li { float: left; } .header li a { padding: 20px 30px; } #rmb_call { float: left; } #rmb_call:hover { padding: 20px 30px; } .header .menu { clear: none; float: right; max-height: none; } .header .menu-icon { display: none; } }
