Angular：無法綁定選擇選項

Question

我想綁定選擇框的選項值。

<select class="form-control" required name="status" id="status" [ngModel]="status" #status="ngModel">
    <option value="ONE"  [ngValue]="status">Active</option>
    <option value="ZERO"  [ngValue]="status">Deactive</option>
</select>

我從 API 收到的值如下：

{id: 1, genreName: "Action", genreDescription: "", status: "ZERO"}

另外，當我提交表單時，我看到了控制台日志：

{genre_name: "Action", status: NgModel}

Answer 2

嘗試這個：

<select class="form-control" required name="status" id="status" 
    [ngModel]="data.status" (ngModelChange)="onChange($event)" >
    <option [value]="'ONE'"  >Active</option>
    <option [value]="'ZERO'"  >Deactive</option>
</select>

TS：

 data = {id: 1, genreName: "Action", genreDescription: "", status: "ZERO"}
 onChange(e){
   console.log(e)

 }
