如何在打开的模态组件中访问`BsModalRef`? [英] How to get access to `BsModalRef` in opened modal component?

问题描述

我对Angular 4还是很陌生.我一直在研究Angular 1.5.x，现在使用ngUpgrade混合方法在Angular 4中转换了相同的应用程序. 我在混合应用程序中使用ngx-bootstrap模态组件，以替换现有的模态服务.

I'm quite new to Angular 4.I have been working on Angular 1.5.x and now converting same application in Angular 4 with ngUpgrade hybrid approach. I'm using ngx-bootstrap modal component in my hybrid application in order to replace existing modal service.

我在以下指南 ngx-bootstrap-modal与服务.

此语句If you passed a component to .show() you can get access to opened modal by injecting BsModalRef

我在这里复制相同的示例，

I'm copying same example here,

export class ModalContentComponent {
  public title: string;
  public list: any[] = [];
  constructor(public bsModalRef: BsModalRef) {}  // How do you get bsModalRef here
}

我尝试运行此示例，但是在打开的模式中我从未得到bsModalRef.

I try running this example, but I never get bsModalRef in opened modal.

我也尝试通过content传递bsModalRef，但是它只能用于一种模式，而不能用于嵌套模式.

I also try passing bsModalRef through content, but it work with one modal and failed to work with nested modal.

还有其他方法可以在ModalContentComponent中传递bsModalRef吗?

Is there any other way to pass bsModalRef in ModalContentComponent ?

在此处找到完整的示例，

Find complete example here,

import { Component } from '@angular/core';
import { BsModalService } from 'ngx-bootstrap/modal';
import { BsModalRef } from 'ngx-bootstrap/modal/modal-options.class';

@Component({
 selector: 'demo-modal-service-component',
 templateUrl: './service-component.html'
})
export class DemoModalServiceFromComponent {
 bsModalRef: BsModalRef;
constructor(private modalService: BsModalService) {}

public openModalWithComponent() {
let list = ['Open a modal with component', 'Pass your data', 'Do something else', '...'];
this.bsModalRef = this.modalService.show(ModalContentComponent);
this.bsModalRef.content.title = 'Modal with component';
this.bsModalRef.content.list = list;
setTimeout(() => {
  list.push('PROFIT!!!');
}, 2000);
}
}

/* This is a component which we pass in modal*/

@Component({
 selector: 'modal-content',
 template: `
<div class="modal-header">
  <h4 class="modal-title pull-left">{{title}}</h4>
  <button type="button" class="close pull-right" aria-label="Close" (click)="bsModalRef.hide()">
    <span aria-hidden="true">&times;</span>
  </button>
</div>
<div class="modal-body">
  <ul *ngIf="list.length">
    <li *ngFor="let item of list">{{item}}</li>
  </ul>
</div>
<div class="modal-footer">
  <button type="button" class="btn btn-default" (click)="bsModalRef.hide()">Close</button>
</div>
 `
})
 export class ModalContentComponent {
  public title: string;
  public list: any[] = [];
  constructor(public bsModalRef: BsModalRef) {} // How do you get bsModalRef here

 }

推荐答案

通过使用

从'ngx-bootstrap'导入{BsModalRef};

import { BsModalRef } from 'ngx-bootstrap';
