如何在单击时隐藏可折叠的Bootstrap 4导航栏
我使用Bootstrap 4很好地创建了这个可折叠的导航栏,但是我希望当用户单击链接时将其关闭。有什么办法吗?谢谢
html导航栏:
<nav class="navbar navbar-toggleable-md fixed-top"><button id="nav-btn"class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarDiv" aria-expanded="false" aria-label="Toggle navigation">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<div class="container">
<a class="navbar-brand" href="#"><img src="Images/logo.png" width="60px"></a>
<div class="collapse navbar-collapse" id="navbarDiv">
<ul class="navbar-nav mr-auto">
<li class="nav-item active">
<a class="nav-link" href="#home">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#about-us">About</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#pricing">Pricing</a>
</li>
</ul>
</div>
</div>
</nav>
.icon-bar的css,因为Bootstrap 4不使用icon-bar类。
.navbar-toggler .icon-bar { margin: 7px;
display: block;
width: 22px;
height: 1px;
background-color: #cccccc;
border-radius: 1px;
}
回答:
您可以collapse
像这样将组件添加到链接。
<ul class="navbar-nav mr-auto"> <li class="nav-item active">
<a class="nav-link" href="#home" data-toggle="collapse" data-target=".navbar-collapse.show">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#about-us" data-toggle="collapse" data-target=".navbar-collapse.show">About</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#pricing" data-toggle="collapse" data-target=".navbar-collapse.show">Pricing</a>
</li>
</ul>
,(也许是一种更好的方法)像这样使用jQuery。
$('.navbar-nav>li>a').on('click', function(){ $('.navbar-collapse').collapse('hide');
});
