我正在设计一个类似手风琴的布局，并希望在我点击div时切换我显示的箭头图标。我能够切换div的内容。我想用箭头图标做同样的事情。
这是我到目前为止所尝试过的。
$(document).ready(function() {
$(this).on("click", ".koh-faq-question", function() {
$(this).parent().find(".koh-faq-answer").toggle();
});
});.koh-faqs-page-title {
font-family: Nexa W01 Heavy;
font-size: 30px;
color: #04202E;
font-weight: 700;
}
.koh-faq-question-span {
font-family: Helvetica Neue LT Pro Roman !important;
font-size: 16px !important;
color: #000 !important;
font-weight: 700 !important;
display: inline-block;
}
.koh-faq-answer {
font-family: Helvetica Neue LT Pro Roman;
color: #000;
font-weight: 400;
display: none;
}
.icon {
font-size: 10px;
padding-right: 5px;
}<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="koh-tab-content">
<div class="koh-tab-content-body">
<div class="koh-faq">
<div class="koh-faq-question">
<i class="fa fa-chevron-right" aria-hidden="true"></i>
<span class="koh-faq-question-span"> Test Question 1 </span>
</div>
<div class="koh-faq-answer">
Test Answer 1
</div>
</div>
</div>
</div>
我希望右键图标在点击问题时切换到向下图标。当我再次点击时，它应该切换回左图标。由于它是一个FAQ页面，我将有多个问题和答案。所以我想为每个人做这件事。

您可以在.fa上切换活动课程以旋转动画图标。
$(document).ready(function() {
$(this).on("click", ".koh-faq-question", function() {
$(this).parent().find(".koh-faq-answer").toggle();
$(this).find(".fa").toggleClass('active');
});
});.koh-faqs-page-title {

只需将fa-chevron-right班级切换为fa-chevron-down班级即可。
我已将$('#chevron').toggleClass( "fa-chevron-right" ).toggleClass( "fa-chevron-down" );此行和chevron ID添加到i代码。
$(document).ready(function() {
$(this).on("click", ".koh-faq-question", function() {
$('#chevron').toggleClass( "fa-chevron-right" ).toggleClass( "fa-chevron-down" );
$(this).parent().find(".koh-faq-answer").toggle();
});

虽然到目前为止所有的答案都很好，并且会完成工作，但我建议你只使用one css state class来完成所有的样式。此外，我们应该尽可能地概括事物，以便解决方案可以轻松应用于其他所有项目，因为手风琴很常见。
您可以使用BEM标准，但不要求 - ＆gt; http://getbem.com/introduction/
步骤如下：
有一个className＆＃39;有效＆＃39; || ＆＃39;开放＆＃39; ||任何和样式（隐藏，显示，旋转等）文本和使用该类切换btn，如下所示：.accordion-item.active .toggle-btn {
your stlyes here
}
使用JS在父（.accordion-item）上添加切换类名，方法是单击切换btn。
