angular - 角度选择更改事件 - 类型“EventTarget”上不存在属性“值”

Question

<select class="form-control form-control-sm (change)='selectPartner($event.target.value)' [formControl]='toControl(itemForm.get("invoice").get("idPartner"))'>
   <option [value]="partner.partnerId" *ngFor="let partner of partners"[selected]='currentPartner&&currentPartner.partnerId==partner.partnerId'>
      {{partner.shortName}}
   </option>
</select>

我收到错误消息Property 'value' does not exist on type 'EventTarget'.我做错了什么？
