我怎样才能折叠所有表格行

Question

我在表内有表行，在每行内还有另一个嵌套表行，我的问题是我可以在嵌套表行中折叠和展开，但是当我尝试在主表中展开时，只有第一行展开当我启动程序时，其余部分默认展开，我该如何修复它。这是我的代码tbody.collapse.in {  display: table-row-group;}.tigray {  background-color: darkcyan;}.zoba {  background-color: forestgreen;}<!-- Latest compiled and minified CSS --><link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"><!-- jQuery library --><script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script><!-- Latest compiled JavaScript --><script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script><table class="table table-bordered table-sm ">  <thead class="thead-dark">    <tr>      <th></th>      <th>head1</th>      <th>head2</th>    </tr>  </thead>  <tbody>    <tr class="clickable" data-toggle="collapse" data-target="#group-of-rows-1" aria-expanded="false" aria-controls="group-of-rows-1">      <td class="tigray">title1</td>      <td class="tigray">35</td>      <td class="tigray">35</td>    </tr>  </tbody>  <tbody id="group-of-rows-1" class="collapse">    <tr class="clickable" data-toggle="collapse" data-target="#group-of-rows-2" aria-expanded="false" aria-controls="group-of-rows-2">      <td class="zoba">nested 1</td>      <td class="zoba">29</td>      <td class="zoba">29</td>      <tbody id="group-of-rows-2" class="collapse">        <tr class="table-warning">          <td>nested title1</td>          <td>13</td>          <td>13</td>        </tr>        <tr class="table-warning">          <td>nested title2</td>          <td>18</td>          <td>13</td>        </tr>        <tr class="table-warning">          <td>nested title 3</td>          <td>32</td>          <td>13</td>        </tr>      </tbody>    </tr>

Answer 1

您不能在另一个 tbody 中使用 tbody， 它不是合法的 HTML。

按照这个代码 ↓↓

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">

<!-- jQuery library -->

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>

<table class="table table-bordered table-sm ">

  <thead class="thead-dark">

    <tr>

      <th></th>

      <th>head1</th>

      <th>head2</th>

    </tr>

  </thead>

  <tbody>

    <tr class="clickable" data-toggle="collapse" data-target=".group-of-rows-1" aria-expanded="false" aria-controls="group-of-rows-1">

      <td class="tigray">title1</td>

      <td class="tigray">35</td>

      <td class="tigray">35</td>

    </tr>

  </tbody>

  <tbody id="" class="collapse group-of-rows-1">

    <tr class="clickable" data-toggle="collapse" data-target="#group-of-rows-2" aria-expanded="false" aria-controls="group-of-rows-2">

      <td class="zoba">nested 1</td>

      <td class="zoba">29</td>

      <td class="zoba">29</td>

      

    </tr>

  </tbody>

  <tbody id="group-of-rows-2" class="collapse">

      <tr class="table-warning">

        <td>nested title1</td>

        <td>13</td>

        <td>13</td>

      </tr>

      <tr class="table-warning">

        <td>nested title2</td>

        <td>18</td>

        <td>13</td>

      </tr>

      <tr class="table-warning">

        <td>nested title 3</td>

        <td>32</td>

        <td>13</td>

      </tr>

    </tbody>

  <tbody id="" class="collapse group-of-rows-1">

    <tr class="clickable" data-toggle="collapse" data-target="#group-of-rows-3" aria-expanded="false" aria-controls="group-of-rows-3">

      <td class="zoba">nested 2</td>

      <td class="zoba">29</td>

      <td class="zoba">29</td>

      

    </tr>

    </tbody>

  <tbody id="group-of-rows-3" class="collapse">

      <tr class="table-warning">

        <td>nested title4</td>

        <td>13</td>

        <td>13</td>

      </tr>

      <tr class="table-warning">

        <td>nested title5</td>

        <td>18</td>

        <td>13</td>

      </tr>

      <tr class="table-warning">

        <td>nested title 6</td>

        <td>32</td>

        <td>13</td>

      </tr>

    </tbody>

</table>

但是，您可以在单个 TABLE 元素中拥有多个 TBODY 元素，因此您可以执行以下操作：

<table> 

  <tbody> 

    <tr> 

      <td>...</td> 

      <td>...</td> 

    </tr> 

  </tbody>

  <tbody > 

    <tr> 

      <td>...</td> 

      <td>...</td> 

    </tr> 

  </tbody>

  <tbody> 

    <tr> 

      <td>...</td> 

      <td>...</td> 

    </tr> 

  </tbody>

</table>
