モバイルAngularUI-スクロール可能な領域

固定配置要素の一部のデバイスで直面する問題があります。スクロール可能な領域を操作するために、Mobile Angular UIはoverflow：autoを利用します。

スクロール可能領域のテンプレートは次のとおりです-

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

スクロール可能な領域にヘッダーとフッターを追加する

cssクラス.scrollable-header / .scrollable-footerを追加すると、必要なスクロール可能領域に固定ヘッダー/フッターが追加されます。高さや位置を気にする必要はありません。cssがすべてを処理します。

ヘッダー/フッターのテンプレートを以下に示します-

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

スクロール可能な領域のディレクティブ

以下は、スクロール可能な領域を操作するときに非常に役立つディレクティブです-

uiScrollTop−スクロールが一番上に達したときに何かをしたいときに使用します。たとえば、ui-scroll-top = "callyourfunc（）"です。

uiScrollBottom−スクロールが一番下に達したときに何かをしたいときに使用します。たとえば、ui-scroll-bottom = "callyourfunc（）"です。

uiScrollableHeader−スクロールがヘッダーに到達したときに何かをしたいときに使用します。たとえば、ui-scroll-header = "callyourfunc（）"です。

uiScrollableFooter−スクロールがフッターに達したときに何かをしたいときに使用します。たとえば、ui-scroll-footer = "callyourfunc（）"です。

uiScrollBottomディレクティブの例-

<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>

これは、スクロール可能な領域の実際の例です。
