展开和折叠 HTML table

Question

免责声明：我是 HTML、javascript 和 CSS 新手。

我想要做的是 expandable/collapsible HTML table 如下所示。单击 "Values 1" 应显示 "Category 1"（还有其他类别，但为了最小化代码，我只显示了 1 个类别）。然后单击 "Category 1" 将显示更多子值。问题是单击 "Values 1" 时它仅隐藏 "Category 1" 而仍显示子值。任何想法我如何可以通过最少的代码更改轻松更改它，以便单击值 1 隐藏类别 1 和子值。请注意，还有更多类别和子值，因此也需要隐藏它们。

理想情况下，单击 "Values 1" 应该隐藏所有类别和子值，而再次单击它应该将类别和子值恢复到它们之前的任何状态，隐藏或可见。

希望这是有道理的。提前致谢

嗨，据我所知，你应该在 expandFRED 中切换隐藏 class class点击事件切换整个table下面是总代码

请申请css

$(document).ready(function() {
  $('[data-toggle="toggle"]').change(function() {
    $(this).parents().next('.hide').toggle();
  });
});

$(document).ready(function() {
  $(".expandFRED").click(function() {
    $(".expandSUB1").toggle();
  });
  $(".expandVALS").click(function() {
    $(".expandCAT1").toggle();
  });
  $(".expandFRED").click(function() {
    $(".hide").toggle();
  });
})

.imagetable {
  border: 1px solid black;
}

.label tr td label {
  display: block;
  border: 1px solid black;
}

td {
  border: 1px solid black;
}

[data-toggle='toggle'] {
  display: block;
}


/*.expandSUB1 {
            display: block;
        }

        .expandFRED {
            display: block;
        }

            .expandCAT1 {
                display: block;
            }*/

<table class='imagetable' align='center'>
  <caption><b></b></caption>
  <tbody class="labels">
    <tr>
      <td class='expandFRED' colspan='7'>

Answer 2

已编辑：

替换为以下代码：

$(".expandFRED").click(function() {
  $('.hide').toggle();  
});
$(".expandVALS").click(function() {
  $(".expandCAT1").toggle();
});

CSS 更改:

.hide {
  display: none;
}

并删除以下内容：

.expandSUB1 {
   display: none;
}

$(document).ready(function() {
    $(".expandFRED").click(function() {
      $('.hide').toggle();  
    });
    $(".expandVALS").click(function() {
      $(".expandCAT1").toggle();
    });
  })

.hide {
  display: none;
}

.expandCAT1 {
  display: none;
}
