从Navbar链接移动到Div/ID

Question

好的，所以我有一个导航栏，当点击一个链接时，我希望它移动到一个特定的div（即当点击“关于”链接时，页面移动到页面的关于部分）。

守则的问题上JSFiddle：

HTML的问题：

<nav class="navbar navbar-toggleable-lg sticky-top navbar-inverse bg-inverse"> 
    <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation"> 
    <span class="navbar-toggler-icon"></span> 
    </button> 
    <a class="navbar-brand" href="#">David Madrigal's Portfolio</a> 

    <div class="collapse navbar-collapse" id="navbarSupportedContent"> 
    <ul class="navbar-nav mr-auto"> 
     <li class="nav-item active"> 
     <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a> 
     </li> 
     <li class="nav-item"> 
     <a class="nav-link" href="#About">About</a> 
     </li> 
     <li class="nav-item"> 
     <a href="#" class="nav-link projects">Projects</a> 
     </li> 
     <li class="nav-item"> 
      <a class="nav-link" href="#">Contact</a> 
     </li> 
    </ul> 
    </div> 
</nav> 

该计划是添加将匹配的页面的部分的ID名字，我要去上课。

这里是JS我到目前为止：

function main() { 
$ 
$('.nav-item').on('click', function() { 
    $(this).toggleClass('active'); 
}); 
} 
$(document).ready(main); 

请注意，我用的引导4.0。任何帮助非常感谢。提前感谢！

这里是一个平滑滚动的解决方案（jQuery的苗条库不支持动画属性） 下面的代码片段

$('a[href^="#"]').on('click', function(event) { 
 
    var target = $(this.getAttribute('href')); 
 
    if (target.length) { 
 
    event.preventDefault(); 
 
    $('html, body').animate({ 
 
     scrollTop: target.offset().top 
 
    }, 1000); 
 
    } 
 
});

body { 
 
    background: #f5f5dc; 
 
} 
 

 
.jumbotron { 
 
    text-align: center; 
 
    background: url(imgs/los-angeles-skyline.jpg); 
 
    background-size: cover; 
 
    background-repeat: no-repeat; 
 
    color: white; 
 
    border-radius: 0; 
 
} 
 

 
#bootstrap-link { 
 
    text-decoration: none; 
 
    color: white; 
 
} 
 

 
#bootstrap-link:hover { 
 
    text-decoration: underline; 
 
    color: #014c8c; 
 
} 
 

 
#info-cards { 
 
    margin-bottom: 20px; 
 
    padding-bottom: 5px; 
 
} 
 

 
#card-blocks { 
 
    padding-bottom: 20px; 
 
    margin-bottom: 20px; 
 
} 
 

 
.card-button { 
 
    margin-left: 5px; 
 
    margin-right: 5px; 
 
} 
 

 
#form-container { 
 
    border: 5px solid rgba(220, 220, 220, 0.4); 
 
    margin-top: 10px; 
 
    padding: 30px; 
 
    padding-bottom: 25px; 
 
    background: #ffffff; 
 
} 
 

 
.form-button { 
 
    margin-top: 20px; 
 
} 
 

 
.footer { 
 
    text-align: center; 
 
    background-color: #292b2c !important; 
 
    padding-bottom: 5px; 
 
    padding-top: 20px; 
 
    margin-top: 5px; 
 
    margin-bottom: 0; 
 
}

Answer 2

你错过了身份证，只需要加一个标识在部分容器中，你的情况：

<div class="container-fluid" id="About">

，因为在你的锚你跳转到#About

<a class="nav-link" href="#About">About</a>
