我想用If条件更新我的FormGroup

Question

这是我的FormGroup

subcomponents

}）

我想在If条件中将此分支更新为必需的分支。我试图喜欢这个

repairFacilityForm = new FormGroup({

languageTypeId: new FormControl("", Validators.required),
repairFacilityId: new FormControl(""),
timeZone: new FormControl("", Validators.required),
name: new FormControl("", Validators.required),
address: new FormControl("", Validators.required),
branch: new FormControl(""),

}

但它无效

Answer 1

您可以使用setValidators添加验证器

this.repairFacilityForm.controls["branch"].setValidators(Validators.required);

Answer 2

尝试这样

languageTypeId: new FormControl("", [Validators.required]),

在数组块中添加验证
