As described in ng-bootstrap NgbModal "A service to open modal windows" and it has no properties to open modal window in new browser window.

I've created the same app as you:

angular 4.1.0-beta.0
bootstrap 4.0.0-alpha.6
ng-bootstrap 1.0.0-alpha.22

And modal windows works as expected, here is content of my app

app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { NgbModule } from '@ng-bootstrap/ng-bootstrap';

import { AppComponent } from './app.component';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    NgbModule.forRoot()
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

index.html (I use Bootstrap CDN)

</html>

app.component.ts

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

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})

export class AppComponent {
  closeResult: string;

  constructor(private modalService: NgbModal) {}

  open(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}`;
    }
  }
}

app.component.html

<template #content let-c="close" let-d="dismiss">
  <div class="modal-header">
    <h4 class="modal-title">Modal title</h4>
    <button type="button" class="close" aria-label="Close" (click)="d('Cross click')">
      <span aria-hidden="true">&times;</span>
    </button>
  </div>
  <div class="modal-body">
    <p>One fine body&hellip;</p>
  </div>
  <div class="modal-footer">
    <button type="button" class="btn btn-secondary" (click)="c('Close click')">Close</button>
  </div>
</template>

<button class="btn btn-lg btn-outline-primary" (click)="open(content)">Launch demo modal</button>

<hr>

<pre>{{closeResult}}</pre>

Solution 2

//1. The modal component has to be registered in entryComponents (angualr 8 and prev)

//1. The modal component has to be registered in entryComponents (angualr 8 and prev)

 entryComponents: [
    YourModalComponent
  ],
  providers: [
   ...]

//2. also the model directly inputted in the open:
  openConfirmUpdateModal() {
 this.modalService.open( YourModalComponent);
 }

I'm new with Angular, and i have a problem while trying the simple example with ng-bootstrap modal. I just tried to have a window open and instead it appears in my application. I'd like to have a new window open as it is explained in the ng-bootstrap example.

I am using: - Angular 4.0.0 - Bootstrap 4.0.0-alpha.6 - @ng-bootstrap/ng-bootstrap 1.0.0-alpha.22

I have in my file.html :

<template #content let-c="close" let-d="dismiss">
        <div class="modal-header">
            <h4 class="modal-title">Modal title</h4>
            <button type="button" class="close" aria-label="Close" (click)="d('Cross click')">
                <span aria-hidden="true">&times;</span>
            </button>
        </div>    
        <div class="modal-body">
            <p>One fine body&hellip;</p>
        </div>
        <div class="modal-footer">
            <button type="button" class="btn btn-secondary" (click)="c('Close click')">Close</button>
        </div>
    </template>

    <button class="btn btn-lg btn-outline-primary" (click)="open(content)">Launch demo modal</button>

    <pre>{{closeResult}}</pre>

and in my file.ts :

import { Component, Input, Output, EventEmitter, ViewContainerRef } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { NgbModal, NgbActiveModal, NgbModalOptions, NgbModalRef, ModalDismissReasons, NgbModalModule } from '@ng-bootstrap/ng-bootstrap';


@Component( {
    selector: 'app-stagiaires',
    templateUrl: './stagiaires.component.html',
    styleUrls: ['./stagiaires.component.css'],
} )


export class StagiairesComponent {

    closeResult: string;

    constructor(private modalService: NgbModal) { }

    open(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}`;
        }
    }
}

I don't have any error showing, it just open the modal in my app instead of a new window and i really don't understand why.

Edit: Here is a screen of my problem : Problem

I have the button "launch demo modal" and when i click on it the "modal title" "one fine body..." appear underneath the button instead of in a modal
