ionic 列表操作

列表是一个应用广泛在几乎所有移动app中的界面元素。ionList 和 ionItem 这两个指令还支持多种多样的交互模式，比如移除其中的某一项，拖动重新排序，滑动编辑等等。

用法

 <ion-list>   <ion-item ng-repeat="item in items">     Hello, {{item}}!   </ion-item> </ion-list>

高级用法: 缩略图，删除按钮，重新排序，滑动

 <ion-list ng-controller="MyCtrl"           show-delete="shouldShowDelete"           show-reorder="shouldShowReorder"           can-swipe="listCanSwipe">   <ion-item ng-repeat="item in items"             class="item-thumbnail-left">      <img ng-src="{{item.img}}">     <h2>{{item.title}}</h2>     <p>{{item.description}}</p>     <ion-option-button class="button-positive"                        ng-click="share(item)">       分享     </ion-option-button>     <ion-option-button class="button-info"                        ng-click="edit(item)">       编辑     </ion-option-button>     <ion-delete-button class="ion-minus-circled"                        ng-click="items.splice($index, 1)">     </ion-delete-button>     <ion-reorder-button class="ion-navicon"                         on-reorder="reorderItem(item, $fromIndex, $toIndex)">     </ion-reorder-button>    </ion-item> </ion-list>
