javascript - Angular如何检查模态是否打开

Question

我正在处理我的 Angular 应用程序的翻译任务并且我正在使用 ngx translate，在检查当前语言是否为阿拉伯语时，我想将模块的文本向右对齐，所以我想检查是否打开了模式我的角度分量，

import { Component, OnInit } from '@angular/core';
import { Router } from '@angular/router';
import { LangChangeEvent, TranslateService } from '@ngx-translate/core';

@Component({
  selector: 'app-plaintes',
  templateUrl: './plaintes.component.html',
  styleUrls: ['./plaintes.component.css']
})
export class PlaintesComponent implements OnInit {


  constructor(public router: Router, public translate: TranslateService, ) { }

  ngOnInit() {
    alert($('#modal-how').hasClass('in'));
    if (localStorage.getItem('defaultLanguage') === "ar") {
      $('#modal-how').css("text-align", "right")
    }
  }



}

<div class="col-4">

        </p>

        {{'procedure.detailemplacement' | translate}}.<br><br>
        <h4><span class="text-gradient-02">{{'procedure.etape2' | translate}}</span> {{'procedure.Choisirletypedeplainte' | translate}}</h4>
        {{'procedure.detailtypeplainte' | translate}}<br><br>

        <i class="la la-check-square-o" style="color: green"></i>
        {{'procedure.garantie' | translate}}
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-primary" data-dismiss="modal">{{'procedure.ok' | translate}}</button>
      </div>
    </div>
  </div>
</div>

我试图提醒模态是否有类（'in'）但它不起作用！有没有办法检查它是否打开！
