从Navbar Link移至Div / ID

标签： javascript jquery html css twitter-bootstrap

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＆＃34;关于＆＃34;链接时，页面移动到关于部分的页面）。

有问题的守则JSFiddle：

有问题的HTML：

<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>

计划是添加与我想去的页面部分的id名称相匹配的类。

这是我到目前为止的JS：

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

注意，我使用的是Bootstrap 4.0。非常感谢任何帮助。谢谢！

您错过了ID，只需在部分容器中添加ID，就您的情况而言：

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

因为在你的主播中你跳到#About

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

这是一个平滑滚动的解决方案（jquery slim libs不支持animate属性）

下面的代码段

＆＃13;
＆＃13; 
$('a[href^="#"]').on('click', function(event) {
  var target = $(this.getAttribute('href'));
  if (target.length) {
    event.preventDefault();
    $('html, body').animate({
      scrollTop: target.offset().top
    }, 1000);
  }
});
＆＃13; 
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;
}
