ionic Listenoperationen

Listen sind Schnittstellenelemente, die in fast allen mobilen Apps weit verbreitet sind. Die Direktiven ionList und ionItem unterstützen auch verschiedene Interaktionsmodi, wie das Entfernen eines Elements, Ziehen zum Neuordnen, Wischen zum Bearbeiten und so weiter.

Nutzung

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

Erweiterte Nutzung: Miniaturansichten, Lösch-Schaltflächen, Neuordnen, Wischen

<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}}.html">
    <h2>{{item.title}}</h2>
    <p>{{item.description}}</p>
    <ion-option-button class="button-positive"
                       ng-click="share(item)">

    <ion-delete-button class="ion-minus-circled"
                       ng-click="items.splice($index, 1)">
    </ion-delete-button>
    <ion-reorder-button class="ion-navicon"
