Позвольте мне показать пример модального диалога подтверждения
ПРОВЕРКА РАБОЧИЙ СТЕКБЛИЦ
Я использую сервис для обмена данными из модального с родительским компонентом
Ваш app.module.ts
что-то вроде: ~
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { ModalModule } from 'ngx-bootstrap/modal';
import { MessageService } from './message.service';
import { ConfirmDialogComponent } from './confirm-dialog/confirm-dialog.component';
@NgModule({
declarations: [
AppComponent,
ConfirmDialogComponent,
],
imports: [
BrowserModule,
ModalModule.forRoot(),
],
providers: [
MessageService,
],
bootstrap: [AppComponent],
entryComponents: [
ConfirmDialogComponent,
]
})
export class AppModule { }
service.ts
может выглядеть примерно так: ~
import { Injectable } from '@angular/core';
import { Observable } from 'rxjs/Observable';
import { BsModalService, BsModalRef } from 'ngx-bootstrap/modal';
import { ConfirmDialogComponent } from './confirm-dialog/confirm-dialog.component';
@Injectable()
export class MessageService {
bsModalRef: BsModalRef;
constructor(
private bsModalService: BsModalService,
) { }
confirm(title: string, message: string, options: string[]): Observable<string> {
const initialState = {
title: title,
message: message,
options: options,
answer: "",
};
this.bsModalRef = this.bsModalService.show(ConfirmDialogComponent, { initialState });
return new Observable<string>(this.getConfirmSubscriber());
}
private getConfirmSubscriber() {
return (observer) => {
const subscription = this.bsModalService.onHidden.subscribe((reason: string) => {
observer.next(this.bsModalRef.content.answer);
observer.complete();
});
return {
unsubscribe() {
subscription.unsubscribe();
}
};
}
}
}
confirm-dialog.component
что-то вроде ниже: ~
export class ConfirmDialogComponent {
title: string;
message: string;
options: string[];
answer: string = "";
constructor(
public bsModalRef: BsModalRef,
) { }
respond(answer: string) {
this.answer = answer;
this.bsModalRef.hide();
}
}
parent.component.ts примерно так: ~
import { Component } from '@angular/core';
import { MessageService } from './message.service';
@Component({
selector: 'my-app',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
answers: string[] = [];
constructor(
private messageService: MessageService,
) {
}
confirm() {
this.messageService.confirm(
"Confirmation dialog box",
"Are you sure you want to proceed?",
["Yes", "No"])
.subscribe((answer) => {
this.answers.push(answer);
});
}
}
