Question

我正在使用Ionic 2。

我有一个页面，当我从另一个页面导航到该页面时，该页面完美滚动。但是，当我从Popover导航到该页面时，页面会显示，但我无法滚动。

有什么想法吗？

从Popover导航到页面，其他页面是相同的：

this.nav.push(CategoryPage, {
  employeeModel: this.employeeModel,
  fromSearch: true
});

页：

<ion-header>
  <ion-navbar>
    <ion-title>{{categoryModel.name}}</ion-title>
  </ion-navbar>
</ion-header>


<ion-content padding>

  <center>
    <ion-spinner icon="android" *ngIf="loading"></ion-spinner>

    <div class="category-text animate-show">
      <div class="select-text" *ngIf="getSelected().length === 0">Select the Roles</div>
      <p class="item-selected-row" *ngFor="let subcategory of getSelected()">
        <img class="item-stable" id="icon-image-{{subcategory.id}}" src="{{subcategory.icon}}" (click)="toggleItem(subcategory)"/>
      </p>
    </div>
  </center>

  <ion-row *ngFor="let trio of getTriples()">
    <ion-col *ngFor="let item of trio">
      <center>
        <div class="row responsive-md">
          {{ formatSubCategories(item) }}
          <img class="item-stable-large" id="icon-image-{{item.id}}" src="{{item.icon}}" (click)="toggleItem(item)"
            [class.item-selected]="isSubCategoryModelItemInArray(item) > -1" />
          <p>{{item.name}}</p>
        </div>
      </center>
    </ion-col>
  </ion-row>

  <ion-buttons>
    <button (click)="next()" block round class="form-button-text">Next</button>
  </ion-buttons>

</ion-content>

Here是解决方案。

elem.on('$destroy', function() {               
                elem.off();
                $log.info('Inside destroy..' + elem);
            });

            scope.$on('$destroy', function() {
                scope = {};                
                $log.info("In destroy of:" + scope);
            });

从Popover滚动不起作用
