Question

我正在使用角4，火基和角度引导。我打开模态，这是一个用户表单，并且想法是在用户使用其中一种登录方法（google auth，facebook auth或email和密码auth）登录后立即关闭模式。但是我无法在需要时找到关闭模态的方法。

google auth

    export class NavComponent implements OnInit {

          @ViewChild('close') public modal: ElementRef;

          constructor() {}


          public openModal(content) {
            this.modalService.open(content).result.then((result) => {
              this.closeResult = `Closed with: ${result}`;
            }, (reason) => {
              this.closeResult = `Dismissed ${this.getDismissReason(reason)}`;
            });
          }    
          private getDismissReason(reason: any): string {
            if (reason === ModalDismissReasons.ESC) {
              return 'by pressing ESC';
            } else if (reason === ModalDismissReasons.BACKDROP_CLICK) {
              return 'by clicking on a backdrop';
            } else {
              return `with: ${reason}`;
            }
          }
         public googleLogin(content): void {
           this.auth.googleAuth().then((res: any) => {
              // close the modal in this moment.
              this.modal.nativeElement.click();
              const user = res.user;
              this.router.navigate(['/gallery']);
            });
         }}

Answer 1

一种简单的方法是隐藏按钮

  <button id="openModalButton" [hidden]="true" data-toggle="modal" data- 
   target="#myModal">Open Modal</button>
  <button id="closeModalButton" [hidden]="true" data-toggle="modal"        
   data-target="#myModal" class="btn btn-default"                          
  data-dismiss="modal">Close</button>

myModal应该是模态的ID名称。打开模式

document.getElementById("openModalButton").click();

关闭模式

document.getElementById("closeModalButton").click();

Answer 2

使用 NgbModal 类方法“dismissall()”关闭模态

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

 constructor(
    private modalService: NgbModal
  )

this.modalService.dismissAll();

Answer 3

按照此步骤

import { Component, ViewChild } from '@angular/core';
import { ModalDirective } from 'ngx-bootstrap/modal';

@Component({
  selector: 'demo-modal-child',
  templateUrl: './child.html'
})
export class DemoModalChildComponent {
@ViewChild('childModal') public childModal:ModalDirective;

public showChildModal():void {
  this.childModal.show();
}

public hideChildModal():void {
  this.childModal.hide();
 }
}

    <button type="button" class="btn btn-primary" (click)="showChildModal()">Open child modal</button>
    <div bsModal #childModal="bs-modal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel" aria-hidden="true">
    <div class="modal-dialog modal-sm">
<div class="modal-content">
  <div class="modal-header">
    <h4 class="modal-title pull-left">Child modal</h4>
    <button type="button" class="close pull-right" aria-label="Close" (click)="hideChildModal()">
      <span aria-hidden="true">&times;</span>
    </button>
  </div>
  <div class="modal-body">
    I am a child modal, opened from parent component!
  </div>
</div>

Answer 4

您可以使用ViewChild：

在你的ts：

@ViewChild('closeModal') closeModal: ElementRef


@Component({
  ...
})
export class NameComponent extends TicketActionsModal {

  @ViewChild('closeModal') closeModal: ElementRef

  ...

}

当您需要关闭模式时，请致电：this.closeModal.nativeElement.click()

例如：

public googleLogin(content): void {
   this.auth.googleAuth().then((res: any) => {
      // close the modal in this moment.
      this.closeModal.nativeElement.click() //<-- here
      const user = res.user;
      this.router.navigate(['/gallery']);
   });
}

在您的html中，将#closeModal添加到按钮：

<button #closeModal type="button" class="close" aria-label="Close" (click)="d('Cross click')">
    <span aria-hidden="true">&times;</span>
</button>

Answer 5

将ID赋予按钮（模式关闭刀口）

let elem = document.getElementById('submitBtn');

let evt = new MouseEvent('click', {
        bubbles: true,
        cancelable: true,
        view: window
    });

elem.dispatchEvent(evt);
