ionic 列表操作

发布于 2018-05-30 05:53:38 字数 5288 浏览 1153 评论 0 收藏 0

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"
           >

    <img ng-src="{{item.img}}">
    <h2>{{item.title}}</h2>
    <p>{{item.description}}</p>
    <ion-option-button
                       ng-click="share(item)">
      分享
    </ion-option-button>
    <ion-option-button
                       ng-click="edit(item)">
      编辑
    </ion-option-button>
    <ion-delete-button
                       ng-click="items.splice($index, 1)">
    </ion-delete-button>
    <ion-reorder-button
                        on-reorder="reorderItem(item, $fromIndex, $toIndex)">
    </ion-reorder-button>

  </ion-item>
</ion-list>
