ionic2 离子列表，带有一个按钮，都有(点击)事件 [英] ionic2 ion-list with a button both having (click) event

问题描述

我想要实现的是，当我点击下载按钮时，它应该做其他事情，当点击该项目时，它应该打开一个新窗口

What I am trying to achieve is when I click on the download button it should do somthing else and when clicking on the item it should open a new window

<ion-list>
    <ion-item *ngFor="let reading_material of reading_materials" (click)="gotoReadingMaterial(reading_material)">
        {{reading_material.title}}
        <ion-icon item-right name="download" (click)="downloadMaterial(reading_material)"></ion-icon>
    </ion-item>
</ion-list>

但是当我点击下载按钮时，这两个事件都被点击了.有没有办法在我点击下载按钮时抑制项目事件??

But when I click on the download button, both the events gets hit. Is there a way i can suppress the item event when i click on the download button ??

推荐答案

您可以使用event.stopPropagation();来解决这个问题.

You can solve this issue by using event.stopPropagation();.

请查看这个plunker.

就像你在那里看到的那样，我还将 $event 对象发送给两个方法

like you can see there, I also send the $event object to both methods

<ion-list>
    <ion-item *ngFor="let item of items" (click)="open($event, item)">
        {{ item }}
        <ion-icon (click)="download($event, item)" item-right name="download"></ion-icon>
    </ion-item>
</ion-list>

然后我使用该信息来停止事件的传播，因此单击下载图标时只会执行下载方法

And then I use that information to stop the propagation of the event, so only the download method will be executed when clicking the download icon

  public open(event, item) {
    event.stopPropagation();
    alert('Open ' + item);
  }

  public download(event, item) {
    event.stopPropagation();
    alert('Download ' + item);
  }
