Question

我有一个这方面的JSON对象：

我希望能够对键值执行绑定，也就是说，能够执行array.company（并显示值的内容，例如：＆＃34; Anonymous 3 Company S.A＆＃34）。这可能吗？我只是设法立刻打印整个对象：

<div *ngFor="let sa of serverAttributes">
    {{ sa.key}}
    {{sa.value}}
</div>

这是我的.ts文件：

this.subscriptions = this.cbank.getAssetServerAttributes(this.localCustomer, data[indexx]).subscribe(vres => {
    this.serverAttributes.push(vres[indexx]);
    indexx++;
});

非常感谢！

create a custom pipe to return the list of key and value You could also return an entry containing both key and value:

@Pipe({name: 'keys'})
export class KeysPipe implements PipeTransform {
  transform(value, args:string[]) : any {
    let keys = [];
    for (let key in value) {
      keys.push({key: key, value: value[key]});
    }
    return keys;
  }
}
and use it like that:

<span *ngFor="let entry of content | keys">           
  Key: {{entry.key}}, value: {{entry.value}}
</span>
