我想用角(2/4)的方式来做这个，下面是我所做的:

<div [class.show]="visible" [class.in]="visible" class="modal fade" id="confirm-dialog-modal" role="dialog">
..
</div>`

需要注意的重要事项:

Visible是组件中的一个变量(布尔值)，它控制模态的可见性。 Show和in是引导类。

一个组件& html示例

组件

@ViewChild('rsvpModal', { static: false }) rsvpModal: ElementRef;
..
@HostListener('document:keydown.escape', ['$event'])
  onEscapeKey(event: KeyboardEvent) {
    this.hideRsvpModal();
  }
..
  hideRsvpModal(event?: Event) {
    if (!event || (event.target as Element).classList.contains('modal')) {
      this.renderer.setStyle(this.rsvpModal.nativeElement, 'display', 'none');
      this.renderer.removeClass(this.rsvpModal.nativeElement, 'show');
      this.renderer.addClass(document.body, 'modal-open');
    }
  }
  showRsvpModal() {
    this.renderer.setStyle(this.rsvpModal.nativeElement, 'display', 'block');
    this.renderer.addClass(this.rsvpModal.nativeElement, 'show');
    this.renderer.removeClass(document.body, 'modal-open');
  }

Html

<!--S:RSVP-->
<div class="modal fade" #rsvpModal role="dialog" aria-labelledby="niviteRsvpModalTitle" (click)="hideRsvpModal($event)">
    <div class="modal-dialog modal-dialog-centered modal-dialog-scrollable" role="document">
        <div class="modal-content">
            <div class="modal-header">
                <h5 class="modal-title" id="niviteRsvpModalTitle">

                </h5>
                <button type="button" class="close" (click)="hideRsvpModal()" aria-label="Close">
                    <span aria-hidden="true">&times;</span>
                </button>
            </div>
            <div class="modal-body">

            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-secondary bg-white text-dark"
                    (click)="hideRsvpModal()">Close</button>
            </div>
        </div>
    </div>
</div>
<!--E:RSVP-->

下面的代码用于在openModal()函数上打开modal，在closemmodal()上关闭modal:

      function openModal() {
          $(document).ready(function(){
             $("#myModal").modal();
          });
      }

     function closeModal () {
          $(document).ready(function(){
             $("#myModal").modal('hide');
          });  
      }

/* #myModal是modal弹出窗口的id */

HTML

<!-- Button trigger modal -->
<button type="button" class="btn btn-primary btn-lg">
  Launch demo modal
</button>

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>

JS

$('button').click(function(){
$('#myModal').modal('show');
});

演示JSFIDDLE

你不应该在触发模式的元素(比如按钮)中写入data-toggle="modal"，你可以手动显示模式:

$('#myModal').modal('show');

和藏在一起:

$('#myModal').modal('hide');

同样的事情也发生在我身上。我想通过单击表行打开Bootstrap模式，并获得关于每行的更多详细信息。我用了一个技巧来做到这一点，我称之为虚拟按钮!与Bootstrap的最新版本(v5.0.0-alpha2)兼容。这可能对其他人也有用。

查看此代码片段预览: https://gist.github.com/alireza-rezaee/c60da1429c36351ef4f071dec0ea9aba

简介:

let exampleButton = document.createElement("button");
exampleButton.classList.add("d-none");
document.body.appendChild(exampleButton);
exampleButton.dataset.toggle = "modal";
exampleButton.dataset.target = "#exampleModal";

//AddEventListener to all rows
document.querySelectorAll('#exampleTable tr').forEach(row => {
    row.addEventListener('click', e => {
        //Set parameteres (clone row dataset)
        exampleButton.dataset.whatever = e.target.closest('tr').dataset.whatever;
        //Button click simulation
        //Now we can use relatedTarget
        exampleButton.click();
    })
});

所有这些都是使用relatedTarget属性。(见Bootstrap文档)

尽管Bootstrap的modal提供了一种javascript方式来创建modal，你仍然需要先编写modal的html标记。
