Ngx-Bootstrap has given a package for an open-source tool that contains all core components powered by Angular. In this article, we will learn about the Modal component, which is a cool feature of Ngx-bootstrap.
What Is a Modal Popup?
A modal is a component that is displayed as a popup dialog box over the page.
Prerequisites
- Basic knowledge of Angular.
- Visual Studio Code must be installed.
- Angular CLI must be installed.
- Node must be installed.
Step 1
Let's create a new Angular project using the following NPM command:
ng new modal-example
Step 2
Now, let's create a new component using the following command:
xxxxxxxxxx
ng g c ngx-bootstrap-modal
Step 3
Install ngx-bootstrap from npm using the following command:
xxxxxxxxxx
npm install ngx-bootstrap --save
Or
xxxxxxxxxx
ng add ngx-bootstrap --component modal
This will be added to our root module
Step 4
Now, let's add Bootstrap styles in our index.html file.
For Bootstrap 3
xxxxxxxxxx
<linkhref="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"rel="stylesheet">
For Bootstrap 4
xxxxxxxxxx
<linkhref="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css"rel="stylesheet">
Step 5
Let's add the template in our ngx-bootstrap-modal.component.html.
xxxxxxxxxx
<h2 style="text-align: center;">Example of Ngx-Bootstrap Modal</h2>
<div style="width: fit-content;margin: auto;margin-top: 18px;">
<button type="button" class="btn btn-primary" (click)="openModalWithClass(template)">Open modal</button>
</div>
<br>
<ng-template #template>
<div class="modal-header">
<h4 class="modal-title pull-left">Modal</h4>
<button type="button" class="close pull-right" aria-label="Close" (click)="modalRef.hide()">

</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" (click)="modalRef.hide()">Close</button>
</div>
</ng-template>
Step 6
Now, open the ngx-bootstrap-modal.component.ts file and add the following code in this file:
xxxxxxxxxx
import { Component, OnInit, TemplateRef } from '@angular/core';
import { BsModalService, BsModalRef } from 'ngx-bootstrap/modal';
@Component({
selector: 'app-modal-popup',
templateUrl: './modal-popup.component.html',
styleUrls: ['./modal-popup.component.css']
})
export class ModalPopupComponent implements OnInit {
modalRef: BsModalRef;
constructor(private modalService: BsModalService) { }
ngOnInit() {
}
openModalWithClass(template: TemplateRef<any>) {
this.modalRef = this.modalService.show(
template,
Object.assign({}, { class: 'gray modal-lg' })
);
}
}
The below code is opening the modal popup:
xxxxxxxxxx
this.modalRef = this.modalService.show(template)
And the below code is to hide the opened modal:
xxxxxxxxxx
this.modalRef.hide();
Here, #template is the template reference that works like a trigger for the modal popup. With that, the template reference name modal is popping up.
Step 7
Now, open the app.component.html file and add the following code:
xxxxxxxxxx
<app-modal-popup></app-modal-popup>
Step 8
Let's open the app.module.ts file and add the following code:
xxxxxxxxxx
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
import { ModalPopupComponent } from './modal-popup/modal-popup.component';
import { ModalModule } from 'ngx-bootstrap/modal';
@NgModule({
declarations: [
AppComponent,
ModalPopupComponent
],
imports: [
BrowserModule,
ModalModule.forRoot(),
FormsModule,
ReactiveFormsModule,
],
bootstrap: [AppComponent]
})
export class AppModule { }
Now its time for the Output:
