javascript - 导航栏和 THead 固定顶部

标签 javascript jquery html twitter-bootstrap

我正在创建一个简单的站点，它将显示计算机列表及其一些信息。到目前为止，我已经让所有功能都按照我想要的方式运行，除了我无法在滚动时让 thead 保持固定在导航栏上。我对这一切还很陌生，但我将在下面列出我尝试过的一些事情以及我的网页的简化版本。

  1. 通过 thead 在导航栏/表格周围放置一个 div:不滚动
  2. 使 tbody 可滚动并固定 navbar/thead 的位置: 格式损坏
  3. 只对 thead 应用固定位置:也会破坏格式

非常感谢任何帮助!

JS

$(function() {
  $("#myTable").tablesorter();
});

    $(document).ready(function(){
      $("#myInput").on("keyup", function() {
        var value = $(this).val().toLowerCase();
        $("#myTableSearch tr").filter(function() {
          $(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
        });
      });
});

最佳答案

我们可以使用提供的答案 here作为以下修改的起点:

.table-fixed {
  width: 100%;
}

.table-fixed thead th {
    position: sticky;
    position: -webkit-sticky;
    /*top: 0;*/
    top:55px; /* the height of the fixed nav-bar */
    z-index: 999;
    background-color: #000;
    color: #fff;
}

现在删除 <br>在 nav-bar 之后在你的HTML . 

<nav class="navbar fixed-top navbar-expand-lg navbar-dark bg-dark">
  <a class="navbar-brand" href="#">Navbar</a>
  <button class="navbar-toggler" 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>

  <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="#">Link</a>
      </li>
    </ul>
    <form class="form-inline my-2 my-lg-0">
      <input id="myInput" onkeyup="myFunction()" class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
    </form>
  </div>
</nav>
<!-- remove the br from here, we will tackle this with the top:55px -->
