Mobile Angular UI - 可滾動區域

某些裝置上，固定定位元素存在問題。為了處理可滾動區域，Mobile Angular UI 使用了overflow:auto。

可滾動區域的模板如下：

<div class="scrollable">
   <div class="scrollable-content">...</div>
</div>

在可滾動區域中新增頁首和頁尾

新增css類.scrollable-header/.scrollable-footer，我們將固定頁首/頁尾新增到您想要的可滾動區域。您無需擔心高度和定位，css 將處理所有內容。

頁首/頁尾模板如下所示：

<div class="scrollable">
   <div class="scrollable-header"><!-- ... --></div>
   <div class="scrollable-content"><!-- ... --></div>
   <div class="scrollable-footer"><!-- ... --></div>
</div>

可滾動區域中的指令

以下是使用可滾動區域時非常有用的指令：

uiScrollTop - 當滾動到達頂部時要執行某些操作時使用。例如 ui-scroll-top="callyourfunc()"。

uiScrollBottom - 當滾動到達底部時要執行某些操作時使用。例如 ui-scroll-bottom="callyourfunc()"。

uiScrollableHeader - 當滾動到達頁首時要執行某些操作時使用。例如 ui-scroll-header="callyourfunc()"。

uiScrollableFooter - 當滾動到達頁尾時要執行某些操作時使用。例如 ui-scroll-footer="callyourfunc()"。

uiScrollBottom 指令示例：

<div class="scrollable">
   <div class="scrollable-content section" ui-scroll-bottom="callyourfunc()">
      <ul>
         <li ng-repeat="a in lists">
            {{a.name}}
         </li>
      </ul>
   </div>
</div>

這是一個可滾動區域的工作示例。
