Question

所以我想在这里实现的很简单，但我似乎无法找到答案。也许这是关键字的错误术语，但我在这里问。我的网站右侧有一个导航栏，其中列出了用户所在的每个特定页面中的所有内容。我想做的是＆＃34;跳＆＃34; /单击列表中的项目时自动滚动到页面中的部分。这是我到目前为止所拥有的。我不知道从哪里开始或开始，我对jquery的理解也是有限的。我不久前就开始学习rails了，我真的很感激一些指导。

我将所有内容分成div标签，并且我已经准备好了link_to按钮。我只是不太确定如何连接两者。

<div class="container">
  <div class="row">
    <div class="col-md-9 aquascaping-content">

      <div class="aquascape-about-intro">
        content//
      </div>

      <div class="aquascape-about-iwagumi">
        content//
      </div>

      <div class="aquascape-about-jungle">
        content//
      </div>

      <div class="aquascape-about-dutch">

      <div class="aquascape-about-parting">

    </div>

    <div class="col-md-3 side-nav">

Answer 1

您需要将ID添加到这样的部门：

<div class="aquascape-about-intro" id="intro">

然后在链接中将此id添加为href，如下所示：

<%= link_to "Intro", "#intro" %>

这会转换为：

<a href="#intro">Intro</a>
<!-- Clicking on this would directly take you to the div with id intro -->

对所有div执行此操作，如下所示。

<div class="container">
  <div class="row">
    <div class="col-md-9 aquascaping-content">

      <div class="aquascape-about-intro" id="intro">
        content//
      </div>

      <div class="aquascape-about-iwagumi" id="about">
        content//
      </div>

      <div class="aquascape-about-jungle" id="jungle">
        content//
      </div>

      <div class="aquascape-about-dutch" id="dutch">
        content//
      </div>

      <div class="aquascape-about-parting" id="parting">
        content//
      </div>

    </div>

    <div class="col-md-3 side-nav">
      <h3 class="page-title", style="padding-left: 20px">Quick Navigation</h3>
      <div class="well well-sm">
        <ul class="side-nav-well">

          <li class="side-nav-item">
            <b>
              <%= image_tag("arrow-icon.png", size: "30x30", alt: "Aquascaping image", class: "side-nav-img")%>
              <%= link_to 'Intro', "#intro" %>
            </b>
          </li>
          <hr>

          <li class="side-nav-item">

              <%= image_tag("arrow-icon.png", size: "30x30", alt: "Aquascaping image", class: "side-nav-img")%>
              <%= link_to 'Iwagumi Aquariums', "#about" %>
            </b>
          </li>
          <hr>
          <li class="side-nav-item">

          </li>
          <hr>
          <li class="side-nav-item">
            <b>
              <%= image_tag("arrow-icon.png", size: "30x30", alt: "Aquascaping image", class: "side-nav-img")%>
              <%= link_to 'Dutch Aquariums', "#dutch" %>

          </li>
          <hr>
          <li class="side-nav-item">
