ngx-formly:如何为自定义控件(如 dateTimePicker)以形式触发模糊事件?

ngx-formly: How to trigger blur event in formly for a custom control like dateTimePicker?

angular 中的自定义控件未正式触发模糊事件。如何为自定义组件绑定模糊事件?我已经为 dateTimePicker 创建了自定义控件,并使用 Material UI 和 angular 版本 9,正式版本 5.5

export class AppComponent {
  form = new FormGroup({});
  model: any = {};
  options: FormlyFormOptions = {};
  fields: FormlyFieldConfig[] = [
    {
      key: "DateTimePicker",
      type: "dateTime",
      templateOptions: {
        label: "Accept terms",
        description: "In order to proceed, please accept terms",
        pattern: "true",
        required: true,
        blur: () => {
          console.log("blur called");
        }
      },
      validation: {
        messages: {
          pattern: "Please accept the terms"
        }
      }
    }
  ];
}

formlyAttributes 指令处理模糊事件,因此请确保它在我们的文档 https://formly.dev/guide/custom-formly-field

中提到的自定义类型中定义
<input type="input"
 [formControl]="formControl"
 [formlyAttributes]="field"
/>

如果它不起作用或您的组件对模糊事件使用不同的输出名称,您必须声明它:

<input type="input"
 (blur)="to.blur ? this.to.blur(this.field, $event): ''"
/>
