typescript angular2 onError 图像绑定

Question

提问by jcdsr

I'm wondering if we can bind or interpolate the onError on the image tag using angular2,

我想知道我们是否可以使用 angular2 绑定或插入图像标签上的 onError，

on the app.component.ts:

在 app.component.ts 上：

imageUrl:string;

  constructor( ) {
      this.imageUrl = 'graphics/placeholder.gif';
   }

on the app.component.html:

在 app.component.html 上：

<img class="img-responsive" [src]="'graphics/image-1.jpg'" onError="imageUrl"/>

The method below works.

下面的方法有效。

<img class="img-responsive" [src]="'graphics/image-1.jpg'" onError="this.src='graphics/placeholder.gif'"/>

But as we using a many images on the app and I would like to make it a simple dynamic solution, I found this answer as well,

但是当我们在应用程序上使用许多图像并且我想让它成为一个简单的动态解决方案时，我也找到了这个答案，

but for some reason is not working, I don't know what I'm doing wrong here

但由于某种原因不起作用，我不知道我在这里做错了什么

Answer 1

It was almost complete he just forgot to change the image after the event.

几乎完成了，他只是在活动结束后忘记改变形象。

errorHandler(event) {
   console.debug(event);
   event.target.src = "https://cdn.browshot.com/static/images/not-found.png";
}
