Framework7 - 手風琴

描述

手風琴是一個圖形控制元件元素，顯示為一個堆疊的專案列表。每個手風琴可以展開或拉伸以顯示與該手風琴關聯的內容。

可摺疊佈局

當您使用單個獨立的可摺疊元素時，您需要省略accordion-list包裝器元素。

以下是可摺疊佈局的結構 -

<!-- Single collapsible element ------>
<div class = "accordion-item">
   <div class = "accordion-item-toggle"></div>
   <div class = "accordion-item-content"></div>
</div>

<!-- Separate collapsible element -->
<div class = "accordion-item">
   <div class = "accordion-item-toggle"></div>
   <div class = "accordion-item-content"></div>
</div>

以下類用於 Framework7 中的手風琴 -

序號	類 & 描述
1	accordion-list 這是一個可選類，包含一組手風琴專案列表。
2	accordion-item 這是單個手風琴專案所需的類。
3	accordion-item-toggle 這是用於展開手風琴專案內容的必需類。
4	accordion-item-content 這是用於隱藏的手風琴專案內容的必需類。
5	accordion-item-expanded 它是一個展開的手風琴專案。

手風琴 JavaScript API

JavaScript API 方法用於以程式設計方式開啟和關閉手風琴。

它包含以下 JavaScript API 方法 -

myApp.accordionOpen(item) - 用於開啟手風琴。
myApp.accordionClose(item) - 用於關閉手風琴。
myApp.accordionToggle(item) - 用於切換手風琴。

所有方法都包含名為item的引數，它是 accordion-item 的 HTML 或字串元素。

手風琴事件

手風琴包含四個事件，如以下表格中列出 -

序號	事件	目標 & 描述
1	open	手風琴專案當您開啟動畫時，將觸發此事件。
2	opened	手風琴專案當動畫開啟完成時，將觸發此事件。
3	close	手風琴專案當您關閉動畫時，將觸發此事件。
4	closed	手風琴專案當動畫關閉完成時，將觸發此事件。

手風琴列表檢視

在手風琴列表檢視中，您可以使用item-link元素代替accordion-toggle。

<div class = "list-block accordion-list">
   <ul>
      <li class = "accordion-item">
         <a href = "" class = "item-link item-content">
            <div class = "item-inner">
               <div class = "item-title">1st Item</div>
            </div>
         </a>
         <div class = "accordion-item-content">Content for 1st Item...</div>
      </li>
      
      <li class = "accordion-item">
         <a href = "" class = "item-link item-content">
            <div class = "item-inner">
               <div class = "item-title">2nd Item</div>
            </div>
         </a>
         <div class = "accordion-item-content">Content for 2nd Item...</div>
      </li>
   </ul>
</div>
