为什么我的离子选择成分没有价值？

Question

我正在尝试从离子选择组件中获取值，而未获取值。当我按Submit时，submitForm会被调用，然后我会console.log记录为空白的AssignedCountry参数。我希望能用一个国家名代替。

打字稿：

      submitForm(
    assignedCountry,
    ..more parameters
  ) {
    let countries = countriesJSON; // a bunch of country names ['USA', 'China' ]
    console.log(assignedCountry); // getting a blank

  }

HTML：

      <form
    [formGroup]="employeeForm"
    (ngSubmit)="
      submitForm(
        assignedCountry.value,

      )
    "
  >
        <ion-select placeholder="Select One" #assignedCountry>
            <ion-select-option
              *ngFor="let country of countries" value="country"
              >{{ country.countryName }}</ion-select-option

          </ion-select>
        <ion-button type="submit">Submit</ion-button>
    </form>
