如何使用Angular5 / 6显示下拉列表选择的项目？

Question

I want to display selected item in Dropdown list based on id.

<div class="formrow" *ngFor='let a of applicantName'>
  <label>Status Selection :</label>
  <select id="AStatus" formControlName="AStatus" class="form-control">
    <option value="0">All</option>
    <option *ngFor="let apt of applicantStatus" [value]="apt.ApplicantStatusID" [selected]="apt.ApplicantStatusID === a.Status">
      {{ apt.ApplicantStatus }}
    </option>
  </select>
</div>

This code is not working and not showing selected option.

Answer 1

value should be set for select not for option.

<div class="formrow" *ngFor='let a of applicantName'>
  <label>Status Selection :</label>
  <select id="AStatus" [value]="apt.ApplicantStatusID" formControlName="AStatus" class="form-control">
    <option value="0">All</option>
    <option *ngFor="let apt of applicantStatus" [value]="apt.ApplicantStatusID">
      {{ apt.ApplicantStatus }}
    </option>
  </select>
</div>
