是否以及如何从Angular 2+模板中的对象中删除键?

伪代码:

    <span 
          (click)="delete objectName.keyName"> cancel 
   </span>

这是一个StackBlitz

https://stackblitz.com/edit/angular-6h5sob?file=src%2Fapp%2Fapp.component.html

<a (click)="delete()">Delete in component</a>

然后

delete() {
  delete this.objectName.keyName
}

在您的模板中

如果我尝试获取(click)=“ delete objectName.keyName”

模板解析错误: 解析器错误:在ng:///AppModule/AppComponent.html@0:12(“] delete objectName.keyName”>删除模板中的[delete objectName.keyName]中的第8列中出现意外的标记'objectName'
