如何通过单击按钮隐藏某些 div？

Question

我正在寻找一种方法，通过使用按钮 onclick 事件来隐藏一定数量的 div。

我知道它可能与 .toggleClass('.AddCSSClassHere') 有关，但我不太确定...我可以隐藏/显示一个 div，但不能父 div 中的特定 div。 jquery 来自我之前想要使用的代码片段。 单击“显示列”按钮时，需要显示或隐藏所有具有 hidethis 类“”的 div

$('button').click(function() {
  $(this).siblings('div').toggleClass('hidethis ');
});

您需要上一级才能找到目标元素作为同级元素。缩进块级元素的内容有助于更好地可视化。

如果您想切换所有容器中的所有此类元素，则需要引入一个新类以在删除该类时跟踪它们，或者将它们全部选中并使用该元素列表。 p>

$(function() {
  const elsToToggle = $('.hidethis');

  $('.show-this-data').click(function() {
    $(this).parent().siblings('div').toggleClass('hidethis ');
  });

  $('.show-all-data').click(function() {
    elsToToggle.toggleClass('hidethis');
  });
});
