Ionic2如何下拉刷新和上拉加载

上拉刷新==>

Html:

  <ion-content style="background-color:white">
    <ion-refresher (ionRefresh)="doRefresh($event)">
        <ion-refresher-content pullingIcon="arrow-dropdown"  pullingText="Pull to refresh"  refreshingSpinner="circles"  refreshingText="Refreshing...">
         </ion-refresher-content>
    </ion-refresher>

TypeScript:

  
    //下拉刷新
    doRefresh(refresher) {
        //console.log('Begin async operation', refresher);
      setTimeout(() => {
          this.BindUserModule();   //绑定方法
       console.log('Async operation has ended');
      refresher.complete();
     }, 1000);
   }
