javascript - 手风琴遇到 jQuery 问题

Question

我目前正在使用 Accordion 和 jQuery 制作 HTML 下拉菜单。例如，在下面的片段中，我有不同级别的 AU 控件。我想用级别等级组织父行，然后在每个级别父行下组织适当的控件。

$(document).ready(function() {
  $('.ui.accordion').accordion();

  /* Alternative way to change color of accordion */
  //$(".drop").css("color", "yellow");
});

/* this doesn't work*/

.ui.styled.accordion .accordion .title,
.ui.styled.accordion .title {
  color: black;
  background-color: #eee;
  cursor: pointer;
  padding: 18px;
  width: 100%;
  height: auto;
  border: none;
  text-align: left;
  outline: none;
  font-size: 15px;
  transition: 0.5s;
}

.ui.styled.accordion .accordion .title,
.ui.styled.accordion .title:hover {
  color: #f2711c;
}

更新： 我已经解决了嵌套问题并且能够解决这个问题。现在我遇到的问题是我认为与 jQuery 相关的问题。当我在 JSFiddle 中运行我的测试用例时，父行打开，并包含我想要的所有正确子行。当我尝试打开子行时，它们会打开半秒钟，然后立即折叠。

好的，在测试并阅读文档后，我发现了问题。您将多个嵌套的 div 与accordion

现在让我们看看您的 html 并尝试找出问题所在。

这是您的原始 Html

<div class="ui stackable grid container">
                    <div class="one column row">
                        <div class="column">
                            <div class="ui styled accordion"> <!-- Accordion parent -->
                                <div class="title"><i class="dropdown icon"></i>Level 2</div>       
                                <div class="content">
                                    <div class="ui divider"></div>
                                    <div class="">
                                        <div class="three column row">
                                            <div class="column">
                                                <div class="ui styled accordion">
                                                    <div class="title drop"><i class="dropdown icon"></i>AU.2.041 Ensure that the actions of individual system users can be uniquely traced to those users so they can be held accountable for their actions.</div>
                                                    <div class="content">
                                                        hi
                                                    </div>
                                                </div>
                                            </div>
                                        </div>
                                    </div>
                                </div>
                            </div>
                        </div>
                    </div> 

现在，如果您仔细观察，您会看到不止一个包含.ui.accordion 触发问题的 div。

最好的解决方案是给 div( ui stackable grid container) 一个新的类或 ID，并尝试将它与这个 ID 绑定。

这是结果

$(document).ready(function(){
    $('.retro').accordion();
  
  /* Alternative way to change color of accordion */
  //$(".drop").css("color", "yellow");
});

/* this doesn't work*/
.ui.styled.accordion .accordion .title, .ui.styled.accordion .title {
    color: black;
  background-color: #eee;
  cursor: pointer;
  padding: 18px;
  width: 100%;
  height: auto;
  border: none;
  text-align: left;
  outline: none;
  font-size: 15px;
  transition: 0.5s;
}

.ui.styled.accordion .accordion .title, .ui.styled.accordion .title:hover {
    color: #f2711c;
}
