如何通过表单控件验证输入类型为time的字段?二手角材料 [英] How to validate field with input type=time via form control? Used Angular Material
问题描述
输入类型为time的字段无法通过表单控件进行验证. 我收到错误消息:
Field with input type=time can't validate via form control. I get error:
错误错误:名称为'thirdCtrl'的表单控件没有值访问器
ERROR Error: No value accessor for form control with name: 'thirdCtrl'
部分代码无法通过Vaildator处理
Part of code, which don't handle via Vaildator
<mat-step [stepControl]="thirdFormGroup">
<form [formGroup]="thirdFormGroup">
<mat-form-field formControlName="thirdCtrl">
<input matInput type="time">
</mat-form-field>
<button mat-button matStepperNext>Next</button>
</form>
</mat-step>
上述表单的简单FormGroup
Simple FormGroup for above form
this.thirdFormGroup = this._formBuilder.group({
thirdCtrl: ['', Validators.required]
});
我怀疑发生错误是因为FormControl尝试处理类型为time的输入字段,但我不知道如何针对我的情况更改此FormControl.
I suspect error occurs because FormControl try to handle input field with type time, but I don't know how to change this FormControl for my case.
推荐答案
尝试将formControlName="thirdCtrl"
绑定从<mat-form-field>
移到<input>
,例如:
Try to move formControlName="thirdCtrl"
binding from <mat-form-field>
to <input>
, like:
<mat-step [stepControl]="thirdFormGroup">
<form [formGroup]="thirdFormGroup">
<mat-form-field>
<input matInput type="time" formControlName="thirdCtrl">
</mat-form-field>
<button mat-button matStepperNext>Next</button>
</form>
</mat-step>
