問題描述

我正在嘗試創建一個手風琴菜單，允許我隱藏我的答案，只出現在問題的點擊。 出於某種原因，當您點擊該問題時，沒有任何反應。

我的代碼： 

 .accordion-Section { background: #fdfdfd; min-height: 100vh; padding: 10vh 0 0; } .accordion-Title { position: relative; margin-bottom: 45px; display: block; font-weight: 600; line-height: 1; } .accordion-Title h2::before { content: ""; position: absolute; left: 50%; width: 60px; height: 2px; background: #E91E63; bottom: -25px; margin-left: -30px; } .accordion-Title p { padding: 0 190px; margin-bottom: 10px; } .faq { background: #FFFFFF; box-shadow: 0 2px 48px 0 rgba(0, 0, 0, 0.06); border-radius: 4px; } .faq .accordion { border: none; background: none; border-bottom: 1px dashed #CEE1F8; } .faq .card .accordionCardHeader { padding: 0px; border: none; background: none; -webkit-transition: all 0.3s ease 0s; -moz-transition: all 0.3s ease 0s; -o-transition: all 0.3s ease 0s; transition: all 0.3s ease 0s; } .faq .card .accordionCardHeader:hover { background: rgba(233, 30, 99, 0.1); padding-left: 10px; } .faq .card .accordionCardHeader .accordion-Title { width: 100%; text-align: left; padding: 0px; padding-left: 30px; padding-right: 30px; font-weight: 400; font-size: 15px; letter-spacing: 1px; color: #3B566E; text-decoration: none !important; -webkit-transition: all 0.3s ease 0s; -moz-transition: all 0.3s ease 0s; -o-transition: all 0.3s ease 0s; transition: all 0.3s ease 0s; cursor: pointer; padding-top: 20px; padding-bottom: 20px; } .faq .card .accordionCardHeader .accordion-Title .badge { display: inline-block; width: 20px; height: 20px; line-height: 14px; float: left; -webkit-border-radius: 100px; -moz-border-radius: 100px; border-radius: 100px; text-align: center; background: #E91E63; color: #fff; font-size: 12px; margin-right: 20px; } .faq .card .card-body { padding: 30px; padding-left: 35px; padding-bottom: 16px; font-weight: 400; font-size: 16px; color: #6F8BA4; line-height: 28px; letter-spacing: 1px; border-top: 1px solid #F3F8FF; } .faq .card .card-body p { margin-bottom: 14px; } @media (max-width: 991px) { .faq { margin-bottom: 30px; } .faq .card .accordionCardHeader .accordion-Title { line-height: 26px; margin-top: 10px; } } 
 <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css"> <body> <section class="accordian-Section"> <div class="container"> <div class="row"> <div class="col-md-6 offset-md-3"> <div class="accordion-Title text-center pb-3"> <h2> About </h2> </div> </div> <div class="col-md-6 offset-md-3"> <div class="faq" id="accordion"> <div class="card"> <div class="accordionCardHeader" id="accordionHeading-1"> <div class="mb-0"> <h5 class="accordion-Title" data-toggle="collapse" data-target="accordionCollapse-1" data-area-expanded="true" data-aria-controls="accordionCollapse-1"> <span class="badge">1</span> What is Lorem Ipsum? </h5> </div> </div> <div id="accordionCollapse-1" class="collapse" aria-labelledby="accordionHeading-1" data-parent="#accordion"> <div class="card-body"> <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. </p> </div> </div> </div> </div> </div> </div> </div> </section> <script src='https://code.jquery.com/jquery-2.1.0.js'></script> <script src='https://maxcdn.bootstrapcdn.com/bootstrap/4.1.3/js/bootstrap.min.js'></script> </body>

預期：單擊問題時，應顯示和折疊折疊式菜單。

實際：當你點擊這個問題時沒有任何反應。

如果聲明data-target它必須是普通的CSS選擇器，那么將data-target="accordionCollapse-1"更改為data-target="#accordionCollapse-1"因為您嘗試打開具有id屬性的div 。

有關詳細信息，請參閱文檔 ！ 

 .accordion-Section { background: #fdfdfd; min-height: 100vh; padding: 10vh 0 0; } .accordion-Title { position: relative; margin-bottom: 45px; display: block; font-weight: 600; line-height: 1; } .accordion-Title h2::before { content: ""; position: absolute; left: 50%; width: 60px; height: 2px; background: #E91E63; bottom: -25px; margin-left: -30px; } .accordion-Title p { padding: 0 190px; margin-bottom: 10px; } .faq { background: #FFFFFF; box-shadow: 0 2px 48px 0 rgba(0, 0, 0, 0.06); border-radius: 4px; } .faq .accordion { border: none; background: none; border-bottom: 1px dashed #CEE1F8; } .faq .card .accordionCardHeader { padding: 0px; border: none; background: none; -webkit-transition: all 0.3s ease 0s; -moz-transition: all 0.3s ease 0s; -o-transition: all 0.3s ease 0s; transition: all 0.3s ease 0s; } .faq .card .accordionCardHeader:hover { background: rgba(233, 30, 99, 0.1); padding-left: 10px; } .faq .card .accordionCardHeader .accordion-Title { width: 100%; text-align: left; padding: 0px; padding-left: 30px; padding-right: 30px; font-weight: 400; font-size: 15px; letter-spacing: 1px; color: #3B566E; text-decoration: none !important; -webkit-transition: all 0.3s ease 0s; -moz-transition: all 0.3s ease 0s; -o-transition: all 0.3s ease 0s; transition: all 0.3s ease 0s; cursor: pointer; padding-top: 20px; padding-bottom: 20px; } .faq .card .accordionCardHeader .accordion-Title .badge { display: inline-block; width: 20px; height: 20px; line-height: 14px; float: left; -webkit-border-radius: 100px; -moz-border-radius: 100px; border-radius: 100px; text-align: center; background: #E91E63; color: #fff; font-size: 12px; margin-right: 20px; } .faq .card .card-body { padding: 30px; padding-left: 35px; padding-bottom: 16px; font-weight: 400; font-size: 16px; color: #6F8BA4; line-height: 28px; letter-spacing: 1px; border-top: 1px solid #F3F8FF; } .faq .card .card-body p { margin-bottom: 14px; } @media (max-width: 991px) { .faq { margin-bottom: 30px; } .faq .card .accordionCardHeader .accordion-Title { line-height: 26px; margin-top: 10px; } } 
 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.3/js/bootstrap.min.js"></script> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css"> <section class="accordian-Section"> <div class="container"> <div class="row"> <div class="col-md-6 offset-md-3"> <div class="accordion-Title text-center pb-3"> <h2> About </h2> </div> </div> <div class="col-md-6 offset-md-3"> <div class="faq" id="accordion"> <div class="card"> <div class="accordionCardHeader" id="accordionHeading-1"> <div class="mb-0"> <h5 class="accordion-Title" data-toggle="collapse" data-target="#accordionCollapse-1" data-area-expanded="true" data-aria-controls="accordionCollapse-1"> <span class="badge">1</span> What is Lorem Ipsum? </h5> </div> </div> <div id="accordionCollapse-1" class="collapse" aria-labelledby="accordionHeading-1" data-parent="#accordion"> <div class="card-body"> <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. </p> </div> </div> </div> </div> </div> </div> </div> </section>

此外，此時data-target設置為h5標記而不是周圍容器。 要解決此問題，您必須刪除h5標記的以下屬性，並使用id="accordionHeading-1"將它們添加到div ：

  • data-target="#accordionCollapse-1"
  • data-area-expanded="true"
  • data-aria-controls="accordionCollapse-1"

我還添加了CSS給框一個pointer光標： 

.accordionCardHeader {
  cursor: pointer;
}


 .accordionCardHeader { cursor: pointer; } .accordion-Section { background: #fdfdfd; min-height: 100vh; padding: 10vh 0 0; } .accordion-Title { position: relative; margin-bottom: 45px; display: block; font-weight: 600; line-height: 1; } .accordion-Title h2::before { content: ""; position: absolute; left: 50%; width: 60px; height: 2px; background: #E91E63; bottom: -25px; margin-left: -30px; } .accordion-Title p { padding: 0 190px; margin-bottom: 10px; } .faq { background: #FFFFFF; box-shadow: 0 2px 48px 0 rgba(0, 0, 0, 0.06); border-radius: 4px; } .faq .accordion { border: none; background: none; border-bottom: 1px dashed #CEE1F8; } .faq .card .accordionCardHeader { padding: 0px; border: none; background: none; -webkit-transition: all 0.3s ease 0s; -moz-transition: all 0.3s ease 0s; -o-transition: all 0.3s ease 0s; transition: all 0.3s ease 0s; } .faq .card .accordionCardHeader:hover { background: rgba(233, 30, 99, 0.1); padding-left: 10px; } .faq .card .accordionCardHeader .accordion-Title { width: 100%; text-align: left; padding: 0px; padding-left: 30px; padding-right: 30px; font-weight: 400; font-size: 15px; letter-spacing: 1px; color: #3B566E; text-decoration: none !important; -webkit-transition: all 0.3s ease 0s; -moz-transition: all 0.3s ease 0s; -o-transition: all 0.3s ease 0s; transition: all 0.3s ease 0s; cursor: pointer; padding-top: 20px; padding-bottom: 20px; } .faq .card .accordionCardHeader .accordion-Title .badge { display: inline-block; width: 20px; height: 20px; line-height: 14px; float: left; -webkit-border-radius: 100px; -moz-border-radius: 100px; border-radius: 100px; text-align: center; background: #E91E63; color: #fff; font-size: 12px; margin-right: 20px; } .faq .card .card-body { padding: 30px; padding-left: 35px; padding-bottom: 16px; font-weight: 400; font-size: 16px; color: #6F8BA4; line-height: 28px; letter-spacing: 1px; border-top: 1px solid #F3F8FF; } .faq .card .card-body p { margin-bottom: 14px; } @media (max-width: 991px) { .faq { margin-bottom: 30px; } .faq .card .accordionCardHeader .accordion-Title { line-height: 26px; margin-top: 10px; } }
