Dependencies

ng2-bs4-modal depends on bootstrap which depends on jquery, you'll need to include both scripts before ng2-bs4-modal:

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.0/jquery.js"></script>
<script src="https://cdn.rawgit.com/twbs/bootstrap/v4-dev/dist/js/bootstrap.js"></script>

Or, if you're using SystemJS, configure it to load them. And import them in your typscript.

Install

> npm install --save ng2-bs4-modal

Include a reference to the bundle in your html:

<script src="node_modules/ng2-bs4-modal/bundles/ng2-bs4-modal.js"></script>

Or, if you're using SystemJS, add a mapping to your System.config:

System.config({
    defaultJSExtensions: true,
    map: {
        'ng2-bs4-modal': 'node_modules/ng2-bs4-modal'
    }
});

Then import into your application or component's module:

import {ModalModule} from 'ng2-bs4-modal/ng2-bs4-modal';

@NgModule({
    imports: [
        ...
        ModalModule,
    ]
    ...
})
export class AppModule {
}

See examples for npm, SystemJS, jspm, and angular-cli.

API

ModalComponent

Inputs

• animation: boolean, default: true

  Specify false to simply show the modal rather than having it fade in/out of view.

• backdrop: string | boolean, default: true

  Specify 'static' for a backdrop which doesn't close the modal on click or false for no backdrop.

• keyboard: boolean, default: true

  Closes the modal when escape key is pressed. Specify false to disable.

• size: string, default: undefined

  Specify 'sm' for small and 'lg' for large.

  Emits when ModalComponent.close() is called.

• onDismiss: EventEmitter

  Emits when ModalComponent.dismiss() is called, or when the modal is dismissed with the keyboard or backdrop.

• onOpen: EventEmitter

  Emits when ModalComponent.open() is called.

Methods

• open(size?: string): Promise

  Opens the modal. Size is optional. Specify 'sm' for small and 'lg' for large to override size. Returns a promise that resolves when the modal is completely shown.

• close(): Promise

  Closes the modal. Causes onClose to be emitted. Returns a promise that resolves when the modal is completely hidden.

  Dismisses the modal. Causes onDismiss to be emitted. Returns a promise that resolves when the modal is completely hidden.

ModalHeaderComponent

  Show or hide the close button in the header. Specify true to show.

ModalFooterComponent

Examples

Default modal

<button type="button" class="btn btn-default" (click)="modal.open()">Open me!</button>

<modal #modal>
    <modal-header [show-close]="true">
        <h4 class="modal-title">I'm a modal!</h4>
    </modal-header>
    <modal-body>
        Hello World!
    </modal-body>
    <modal-footer [show-default-buttons]="true"></modal-footer>
</modal>

Static modal

This will create a modal that cannot be closed with the escape key or by clicking outside of the modal.

<modal #modal [keyboard]="false" [backdrop]="'static'">
    <modal-header [show-close]="false">
        <h4 class="modal-title">I'm a modal!</h4>
    </modal-header>
    <modal-body>
        Hello World!
    </modal-body>
    <modal-footer [show-default-buttons]="true"></modal-footer>
</modal>

Use custom buttons in footer

<modal #modal>
    <modal-header>
        <h4 class="modal-title">I'm a modal!</h4>
    </modal-header>
    <modal-body>
        Hello World!
    </modal-body>
    <modal-footer>
        <button type="button" class="btn btn-default" data-dismiss="modal" (click)="modal.dismiss()">Cancel</button>
        <button type="button" class="btn btn-primary" (click)="modal.close()">Ok</button>
    </modal-footer>
</modal>

Opening and closing the modal from the host/parent component

import { Component, ViewChild } from 'angular/core';
import { ModalComponent } from 'ng2-bs4-modal/ng2-bs4-modal';

@Component({
    selector: 'parent-component',
    template: `
        <modal #myModal>
            ...
        </modal>
    `
})
export class ParentComponent {
    @ViewChild('myModal')
    modal: ModalComponent;

    close() {
        this.modal.close();
    }
    
    open() {
        this.modal.open();
    }
}

Autofocus on a textbox when modal is opened

<modal #modal>
    <modal-header>
        <h4 class="modal-title">I'm a modal!</h4>
    </modal-header>
    <modal-body>
        <div class="form-group">
            <label for="textbox">I'm a textbox!</label>
            <input autofocus type="text" class="form-control" id="textbox">
        </div>
