        </div>
        <button type="button"  (click)="validateUser(user)" class="btn btn-success" >Submit</button>
      </form>
    </div>

我对Angle 2还是陌生的，我在输入标签中尝试了必填属性，但无法正常工作。我也想改变输入错误时的颜色。我试过了，但是我不知道该怎么做。这是代码。

Answer 1

为您的输入字段输入名称，例如name="name"，然后尝试使用此user.name.errors.required而不是user.name.errors

输入字段的必填属性不起作用，输入字段的颜色未更改
