<p>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。</p> <p>我知道它可能与 <code>.toggleClass('.AddCSSClassHere')</code> 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</p> <p> <pre class="brush:js;toolbar:false;">$('button').click(function() { $(this).siblings('div').toggleClass('hidethis '); });</pre> <pre class="brush:css;toolbar:false;">* { margin: 0; padding: 0; } html, body { height: 100%; } body { background: #fff; padding: 0; margin: 0; font-family: Myriad-Pro, Arial, 'Varela Round', sans-serif; font-size: 16px; } .quotation { height: 100%; overflow: auto; } .main-div { position: sticky; top: 0; } .header-div { display: flex; padding: 5px 0; background-color: #fff; } .titles { display: flex; width: 100%; align-items: center; } .currencyinfo { width: fit-content; max-width: 100px; min-width: 100px; text-align: center; padding: 0; } .info { width: fit-content; max-width: 100px; min-width: 100px; text-align: center; padding: 10px 0; } .currency { max-width: 70px; min-width: 70px; } .table-info { display: flex; flex-direction: row; flex-wrap: wrap; width: 100%; overflow-y: scroll; } .main-div-info { display: flex; text-align: center; flex-direction: row; flex-wrap: wrap; width: 100%; } .div-info { display: flex; flex-direction: row; flex-wrap: wrap; width: 100%; padding: 10px 0; align-items: center; } .hidethis { display: none; }</pre> <pre class="brush:html;toolbar:false;"><script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.7.0/jquery.min.js" integrity="sha512-3gJwYpMe3QewGELv8k/BX9vcqhryRdzRMxVfq6ngyWXwo03GFEzjsUm8Q7RZcHPHksttq7/GFoxjCVUjkjvPdw==" crossorigin="anonymous" referrerpolicy="no-referrer"></script> <section class="quotation"> <div class="main-div"> <div class="header-div"> <div class="titles"> <div class="currencyinfo product-title"> <button class="show-this-data">show columns</button> </div> <div class="currencyinfo"></div> <div class="currencyinfo"></div> <div class="currencyinfo"></div>

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');
  });
});
