我从未在我的项目中使用过scrollspy而且我需要知道它是如何工作的。我已经看到了bootstrap页面上的文档,一些其他stackoverflow问题和youtube视频。
我有这段代码:
导航:
<!-- Start nav -->
<nav class="navbar navbar-default navbar-fixed-top">
<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" aria-expanded="false">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#"><img id="logo" src="images/logo.png" alt="Brand"></a>
</div>
<!-- Collect the nav links, forms, and other content for toggling -->
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<li class="active"><a href="#">Link <span class="sr-only">(current)</span></a></li>
<li><a href="#">Link</a></li>
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Dropdown <span class="caret"></span></a>
<ul class="dropdown-menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li role="separator" class="divider"></li>
<li><a href="#">Separated link</a></li>
<li role="separator" class="divider"></li>
<li><a href="#">One more separated link</a></li>
</ul>
</li>
</ul>
<!--<form class="navbar-form navbar-left" role="search">
<div class="form-group">
<input type="text" class="form-control" placeholder="Search">
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>-->
<ul class="nav navbar-nav navbar-right" id="navbar">
<li><a href="#Inicio">Incio</a></li>
<li><a href="#NuestrosServicios">Nuestros Servicios</a></li>
<li><a href="#Portafolio">Portafolio</a></li>
<!--<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Dropdown <span class="caret"></span></a>
<ul class="dropdown-menu">
<li><a href="#Inicio">Action</a></li>
<li><a href="#NuestrosServicios">Another action</a></li>
<li><a href="#Portafolio">Something else here</a></li>
<li role="separator" class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</li>-->
</ul>
</div><!-- /.navbar-collapse -->
</div><!-- /.container-fluid -->
</nav>
<!-- End nav -->
身体:
<!-- Body container -->
<div class="container-fluid">
<div class="row">
<div class="col-md-12 menu-1" id="Inicio"></div>
<div class="col-md-12 menu-2" id="NuestrosServicios"></div>
<div class="col-md-12 menu-3" id="Portafolio"></div>
</div>
</div>
<!-- End Body container -->
JavaScript方面:
$(function() {
$("body").scrollspy({target: "#navbar"});
});
jsbin中的完整示例:
答案 0 :(得分:0)
目标应指示元素id。在您的navbar元素中,我没有看到id属性。尝试将ID添加到导航栏。
同时将position: relative;
css添加到您的body元素。
如果以上内容没有解决问题,请使用body标签中的data-spy="scroll" data-target="#navbar-example"
数据属性而不是javascript,并且不要忘记导航栏元素的id属性。
