How to use MatDialog Angular

Create angular project

To create an Angular project, follow these steps:

1. Install Node.js: Angular requires Node.js and npm (Node Package Manager) to be installed on your machine. Visit the official Node.js website (https://nodejs.org) and download the latest LTS version suitable for your operating system. Follow the installation instructions.

2. Install Angular CLI: Angular CLI (Command Line Interface) is a powerful tool that simplifies the process of creating and managing Angular projects. Open a terminal or command prompt and run the following command to install Angular CLI globally:


npm install -g @angular/cli

3. Create a new Angular project: Once Angular CLI is installed, you can create a new Angular project using the ng new command. Navigate to the directory where you want to create your project using the cd command, and then run the following command:

ng new my-angular-project

4. Replace my-angular-project with the name you want to give to your project. Angular CLI will generate a new project structure with all the necessary files and dependencies. Navigate to the project directory: After the project is created, navigate to the project directory using the cd command:

cd my-angular-project

5. Serve the application: To see your Angular project in action, you can use the Angular CLI's development server. Run the following command to start the server:

ng serve

This will compile the project and launch a development server. Open your web browser and visit http://localhost:4200 to see your Angular application.

Congratulations! You have successfully created an Angular project. You can now start building your application by modifying the files in the project structure, including the main HTML template (src/index.html) and the root component (src/app/app.component.ts). Refer to the official Angular documentation (https://angular.io/docs) for more information on how to work with Angular and build powerful web applications.

Angular material

1. Install required dependencies: Install the necessary dependencies for autocomplete functionality. You'll need @angular/material and @angular/cdkfor the autocomplete component. Run the following command to install them:

npm install @angular/material @angular/cdk

1. Import required modules: Open the app.module.ts file located in the autocomplete folder and import the necessary modules from @angular/material and @angular/forms. Your imports should look like this:

app.module.ts

import { CUSTOM_ELEMENTS_SCHEMA, NgModule } from '@angular/core'; import { BrowserModule } from '@angular/platform-browser'; import { AppComponent } from './app.component'; import { DialogComponent } from './dialog/dialog.component'; import { MatDialogModule } from '@angular/material/dialog'; import {MatDividerModule} from '@angular/material/divider'; import {MatListModule} from '@angular/material/list'; import {MatButtonModule} from '@angular/material/button'; @NgModule({ declarations: [ AppComponent, DialogComponent ], imports: [ BrowserModule, MatDialogModule, MatListModule, MatDividerModule, MatButtonModule ], providers: [], bootstrap: [AppComponent], schemas: [CUSTOM_ELEMENTS_SCHEMA] }) export class AppModule { }

Generate component

To generate a component in Angular, you can use the Angular CLI (Command Line Interface) tool. Here are the steps to generate a component:

1. Open a terminal or command prompt.
2. Navigate to the root directory of your Angular project.
3. Run the following command:


ng generate component dialog

4. The Angular CLI will generate the necessary files and folders for your component in the appropriate location within your project's file structure.

5. Once the process is complete, you can start using your newly generated component in other parts of your Angular application.

The Angular CLI will generate several files for your component, including the component's TypeScript (.ts), HTML (.html), CSS or SCSS (.css or .scss), and a test file for the component.

MatDialog

To use MatDialog in Angular, you need to follow these steps:
1. Inject MatDialog into your component:
In the constructor of your component, inject MatDialog:

Open the dialog:
To open the dialog, you can use the open method of the MatDialog service. Pass the component you want to display in the dialog as the first argument:

app.component.ts

import { Component } from '@angular/core'; import { DialogComponent } from './dialog/dialog.component'; import { MatDialog } from '@angular/material/dialog'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { constructor(private dialog: MatDialog) { } openDialog(enterAnimationDuration: string, exitAnimationDuration: string): void { const dialogRef = this.dialog.open(DialogComponent, { width: '400px', enterAnimationDuration, exitAnimationDuration, data: { name: 'John', age: 30, address: "1 Paris street", phone: "0989452028", email: "email@gmail.com" } }); dialogRef.afterClosed().subscribe(result => { console.log('The dialog was closed'); console.log('Result:', result); }); } }

Open dialog

Add the dialog opener:
In your template, add a button or any other trigger element to open the dialog:

app.component.html

<div class="content" role="main"> <button mat-stroked-button style="color: #fff !important; background: #d35400;" (click)="openDialog('2000ms', '1000ms')">Open Dialog</button> </div>

DialogComponent

In the above code, DialogComponent is the component that will be displayed inside the dialog. You can pass optional configuration options as the second argument, such as the width and initial data for the dialog component.

Create the dialog component:
Create a new component that will be displayed inside the dialog. This component should have its own template and logic. For example:

dialog.component.html

<h1 style="margin-left: 20px;">Dialog</h1> <div mat-dialog-content> <h2>Received data:</h2> <mat-list> <mat-divider></mat-divider> <mat-list-item>Name: {{data.name}}</mat-list-item> <mat-divider></mat-divider> <mat-list-item>Age: {{data.age}}</mat-list-item> <mat-divider></mat-divider> <mat-list-item>Phone: {{data.phone}}</mat-list-item> <mat-divider></mat-divider> <mat-list-item>Email: {{data.email}}</mat-list-item> <mat-divider></mat-divider> <mat-list-item>Address: {{data.address}}</mat-list-item> <mat-divider></mat-divider> </mat-list> </div> <div mat-dialog-actions> <button mat-raised-button style="color: #fff !important; background: #e74c3c;" (click)="onClose()">Close</button> </div>

MAT_DIALOG_DATA

In the above example, MAT_DIALOG_DATA is used to inject the data passed to the dialog into the component.

dialog.component.ts

import { Component, Inject } from '@angular/core'; import { MatDialogRef, MAT_DIALOG_DATA } from '@angular/material/dialog'; @Component({ selector: 'app-dialog', templateUrl: './dialog.component.html', styleUrls: ['./dialog.component.css'] }) export class DialogComponent { constructor( public dialogRef: MatDialogRef<DialogComponent>, @Inject(MAT_DIALOG_DATA) public data: any ) { } onClose(): void { this.dialogRef.close('Dialog closed'); } }

That's it! You've successfully used MatDialog to open a dialog in Angular. Remember to import the necessary MatDialogModule and other required modules in your app module file.
