解除/关闭时的嵌套NgbModal问题

import { NgbModal, ModalDismissReasons } from '@ng-bootstrap/ng-bootstrap';

activeModal: any;

openFirstModal(content: any) {
  this.activeModal = this.modalService.open(content);
}

openSecondModal(content: any) {
  this.activeModal.close(); // 关闭第一个弹窗
  this.activeModal = this.modalService.open(content);
}

closeModal() {
  this.activeModal.dismiss(ModalDismissReasons.BACKDROP_CLICK); // 关闭弹窗并设置关闭原因
}

// 在组件初始化时监听关闭事件
ngOnInit() {
  this.activeModal.result.then((result: any) => {
    if (result === ModalDismissReasons.BACKDROP_CLICK) {
      // 处理关闭原因为点击背景的情况
    } else if (result === ModalDismissReasons.ESC) {
      // 处理关闭原因为按下ESC键的情况
    } else {
      // 处理其他关闭原因
    }
  });
}
