我们可以使用单个离子文本区域发表评论，同时回复评论吗？

Question

当我单击回复按钮时，我将焦点重定向到已经用于发布评论的文本字段，现在我希望该文本框也发布回复 -调用focusInput（input）时，它将聚焦到页脚中的文本区域-

  <button (click)="focusInput(input)" style="background-color:transparent">
      <p style="color:dodgerblue;font-size: 16px">Reply</p>
        </span></button>
  <ion-footer>
  <ion-list style="text-align: center">
  <ion-row>
      <ion-col>
      <ion-item text-wrap> 
            <ion-textarea  #input type="text" id="myInput1"  [(ngModel)]="body" placeholder="Write a Comment" spellcheck="true" autoComplete="true" autocorrect="true" autosize></ion-textarea>  
      </ion-item> 
      </ion-col>
      <button (click)="postComments(commentsList.id,i)" icon-only item-right class="send-chat-button" style="background-color: transparent">
      <ion-icon name="send" style="color:orange"></ion-icon>
      </button>
    </ion-row>
  </ion-list>


  //.ts file
     focusInput(input) {
      input.setFocus();
    }

    postComments() {
//console.log(this.userDetails)
let commentPost = {
  "post_id": this.commentsList.id,
  "body": this.body,
 "user" :{ "name":this.userDetails.name,"photo": {"file":this.userDetails.photo.file}},

}
this.service.postComment(commentPost)
  .subscribe(data => {
    this.returndata = data;
    console.log(this.returndata)
   //this.commentsList.comment.push(this.returndata)
  })
  this.commentsList.comment.push(commentPost);
this.body = "";

}
