我有一个导航菜单。这个菜单,我用bootstrap构建它,我想让它在向下滚动时隐藏,并在向上滚动时显示。我只使用vanilla JavaScript获得了它的要求。
这是我的HTML代码:
<nav class="navbar navbar-default navbar-fixed-top custom-header" >
<div class="container-fluid">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
<span class="sr-only">Menu</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="" style="color:#FFF">
<img src="img/header-logo.png" alt="Happy Tour" />
</a>
</div>
<!-- This section contains all link buttons in the header -->
<div class="collapse navbar-collapse pull-right mybtn" id="bs-example-navbar-collapse-1" style="margin-top:9px;">
<button class="btn btn-primary btn-md"><i class="glyphicon glyphicon-bookmark"></i> Destinations</button>
<button class="btn btn-success btn-md"><i class="glyphicon glyphicon-th"></i> Tour Package</button>
<button class="btn btn-danger btn-md"><i class="glyphicon glyphicon-file"></i> Book Ticket</button>
<button class="btn btn-info btn-md"><i class="glyphicon glyphicon-search"></i> Find Hotel</button>
<button class="btn btn-success btn-md"><i class="glyphicon glyphicon-user"></i> Register</button>
<button class="btn btn-primary btn-md"><i class="glyphicon glyphicon-fire"></i> Login</button>
</div>
</div>
</nav>
这是一个css:
.custom-header{
padding: 0;
height: 120px;
line-height: 120px;
background: url(../img/top_head_bg.jpg) repeat-x;
border:none;
}
答案 0 :(得分:0)
与本文Auto-Hide Sticky Header建议一样(我也使用这4个字在 Google 中立即找到解决方案),您可以将标题设置为固定< / p>
.header {
width: 100%;
height: 7.5em;
position: fixed;
z-index: 1000;
top: 0;
left: 0;
}
然后对滚动做出反应,使用 JS 更改top
属性。
祝你好运&#39;
