Angular 2 - 打开/关闭默认引导模式

Question

我不想使用 angular2-bootstrap或 ng2-bs3-modal正如问题/答案中所建议的那样 Angular 2 Bootstrap Modal和 Angular 2.0 and Modal Dialog

现在。我知道什么打开和关闭引导模式。

• 显示在 display: none; 和 display: block;
之间切换
• div 上的一个属性在 aria-hidden="true" 和 aria-hidden="false
之间切换

所以，我很自然地认为，如果我像 [aria-hidden]="true" 这样绑定(bind)到 aria-hidden 属性，我就可以操纵它。遗憾的是，我无法绑定(bind)到 aria-hidden，因为它不是 div 的已知属性。 (注意，attr.aria-hidden 不存在)

我知道这可以通过带有 $('#myModal').modal() 的 JQuery 实现，如问题 How to open a Bootstrap modal window using jQuery? 所示。

所以我的问题是，是否有一个 TypeScript 功能与 JQuery 中的 modal() 做同样的事情，或者是否有一种方法可以将函数/变量绑定(bind)到 aria-hidden ?

我当前的 html:

<div id="createAccountModal" class="modal fade customForm" role="dialog" [aria-hidden]="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <h4>Create account</h4>
            </div>
            <div class="modal-body">
               <p>Lorem ipsum</P>
            </div>
            <div class="modal-footer align-left">
                My custom footer
            </div>
        </div>
    </div>
</div

您可以尝试这样的操作，创建 myModal.html:

<div class="modal-backdrop fade in" [style.display]="showModal ? 'block' : 'none'"></div>
  <div class="modal" tabindex="-1" role="dialog" style="display: block" [style.display]="showModal ? 'block' : 'none'">
     <div class="modal-dialog">
        <div class="modal-popup">
          <div class="popup-title">
            <span>{{title}} </span>
            <i class="icon-cancel fr" data-dismiss="modal" aria-label="Close" (click)="cancelAction()"></i>
            <p *ngIf="subTitle">{{subTitle}}</p>
          </div>
        <ng-content></ng-content>
      </div>
  </div>
</div>

然后，创建myModal.component.ts:

import { Component, Input, Output, EventEmitter, OnInit } from '@angular/core';

const template: string = require('./myModal.html');

@Component({
   selector: 'modal',
   template
})

export class Modal implements OnInit {
  @Input('show-modal') showModal: boolean;
  @Input('title') title: string;
  @Input('sub-title') subTitle: string;
  @Input('cancel-label') cancelLabel: string;
  @Input('positive-label') positiveLabel: string;

  @Output('closed') closeEmitter: EventEmitter < ModalResult > = new EventEmitter < ModalResult > ();
  @Output('loaded') loadedEmitter: EventEmitter < Modal > = new EventEmitter < Modal > ();
  @Output() positiveLabelAction = new EventEmitter();

  constructor() {}

  ngOnInit() {
    this.loadedEmitter.next(this);
  }

  show() {
    this.showModal = true;
  }

  hide() {
    this.showModal = false;
    this.closeEmitter.next({
      action: ModalAction.POSITIVE
    });
  }

  positiveAction() {
    this.positiveLabelAction.next(this);
    return false;
  }

  cancelAction() {
    this.showModal = false;
    this.closeEmitter.next({
      action: ModalAction.CANCEL
    });
    return false;
  }
}

export enum ModalAction { POSITIVE, CANCEL }

export interface ModalResult {
  action: ModalAction;
}

然后为此创建模块，这样你就可以在任何地方使用，像这样在任何地方使用它:

<modal #deleteUserModal id="deleteUser"
   [show-modal]="isModalOpen"
   [title]="'Delete'"
   >
  <div class="popup-content">
    <p>Are you sure you want to delete the user permanently?</p>
  </div>
  <div class="popup-footer">
    <button class="btn cancel"  aria-label="Close" (click)="deleteUserModal.hide()">
        Cancel
    </button>
    <button type="button" class="btn btn-primary" (click)="deleteSelectedUser(deleteUserModal)" aria-label="Close">
        Delete
    </button>
   </div>
 </modal>

你也可以增强它:)
