angular - 为表单控件禁用属性删除数据

Question

我创建了一个包含 FormControl 的 FormGroup 并且我想要一些值应用属性“禁用：真/假”但是如果我编辑其中一个值，另一个是空的......

return this.formBuilder.group({
  civilite: new FormControl({value: personne.civilite || '', disabled: personne.civilite }),
  situationfamiliale: new FormControl({value: personne.situationfamiliale || '', disabled: personne.situationfamiliale }),
});

<div class="col-md-6 col-xl">
        <div class="form-group"> 
            <label for="situationFamiliale">{{'situation' | translate}}</label>
            <ngx-select id="situationFamiliale" [items]="familyStatus" formControlName="situationFamiliale"
                [allowClear]="true" placeholder="{{'CHOOSE_LBL' | translate}}"
                noResultsFound="{{'NO_RESULTS_FOUND_LBL' | translate}}" > 
                <ng-template ngx-select-option-selected ngx-select-option let-option let-text="text" >
                    {{option.data.text | translate}}
                </ng-template>
            </ngx-select>
        </div>
    </div> 
    <div class="col-md-6 col-xl">
        <div class="form-group">
            <label for="civilite">{{'civilite' | translate}}</label>
            <ngx-select id="civilite" [items]="civilities" formControlName="civilite" [allowClear]="true"
                placeholder="{{'CHOOSE_LBL' | translate}}" noResultsFound="{{'NO_RESULTS_FOUND_LBL' | translate}}" >
                <ng-template ngx-select-option-selected ngx-select-option let-option let-text="text" >
                    {{option.data.text | translate}}
                </ng-template>
            </ngx-select>
        </div>
    </div>
