如何根据收到的值检查复选框

Question

了解假设我收到值“是”和“否”。我的问题是我只想在收到“是”时选中复选框。

我试过的代码

<section class="pleft ptop" *ngFor="let item of patientPastMedicalHistoryList">
              <mat-checkbox color="primary"
              (change)="patientPastHistoryForm.get('substanceAbuseAlcohol').setValue(
                $event.checked ? 'Yes' : 'No')" 
                checked="{{item.substanceAbuseAlcohol ==='Yes'}}" 
               >Alcohol</mat-checkbox><br>
              </mat-form-field>
</section>

我试过了 这没有帮助。下面的代码始终选中复选框，即使收到的值为“NO”

[checked]="patientPastHistoryForm.get('substanceAbuseAlcohol').value=='Yes'"

 checked="{{item.substanceAbuseAlcohol ==='Yes'}}"

形式

this.patientPastHistoryForm = new FormGroup({
      patientId: new FormControl(this.clientId),
      substanceAbuseAlcohol: new FormControl(''),})

数据

 patientPastMedicalHistoryList: Array<PatientPastMedicalHistoryModel>=[];

这就是我获取值的方式

  getPatientPastHistoryList() {
    debugger
    this.clientsService.getPatientPastHistoryList(this.clientId)
      .subscribe(
        (response: ResponseModel) => {
          if (response.statusCode === 200) {
            this.patientPastMedicalHistoryList = response.data;                                
          } else {
            this.patientPastMedicalHistoryList = [] ;           
          }
          this.patientPastHistoryForm.patchValue({
            ...response.data,
          })
        });
  }

收到数据

{
  "expires_in": 0,
  "data": [
    {
      "id": 0,
      "patientId": 2143,
      "substanceAbuseAlcohol": "No",
      "substanceAbuseMarijuana": "Yes",
}

response.data是一个数组

你想要this.patientPastHistoryForm.patchValue({ ...response.data[0], })
