.modal('dispose') 有什么作用？引导程序 4

Question

根据文档，.modal('dispose') 会破坏模态。

.modal('dispose')

销毁一个元素的模态。

但是当我使用创建eventListener 时

$('#myModal').on('hidden.bs.modal', function (event) {
    // Destroy modal
    $('#myModal').modal('dispose');
});

模态仍然是文档的一部分。文档让我很困惑，这个方法不是用来从文档中删除模态的吗？这种方法的目的是什么？

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

$('#myModal').on('hidden.bs.modal', function (event) {
  console.log('Destroy modal');
  $('#myModal').modal('dispose');
});

它会破坏 Bootstrap 的 Modal 组件的 jQuery 实例。它不会从 DOM 中删除模态标记。
