How to Close Dialog in Angular using ng Matero Extension?

Are you tired of struggling with dialog boxes in your Angular application? Do you want to learn how to close them with ease using the ng Matero extension? Look no further! In this comprehensive guide, we’ll take you through the step-by-step process of closing dialog boxes in Angular using ng Matero.

What is ng Matero?

Before we dive into the tutorial, let’s quickly cover what ng Matero is. ng Matero is a popular extension for Angular Material that provides a set of reusable UI components, including dialog boxes. It’s built on top of Angular Material and provides a more comprehensive set of features and customizations.

Why Close Dialog Boxes?

Dialog boxes are an essential part of any application. They provide a way to display important information, ask for user input, or prompt the user to take an action. However, they can also be annoying if not closed properly. Imagine a scenario where a user clicks on a button to open a dialog box, and then the dialog box remains open even after the user has taken the desired action. It’s frustrating, right? That’s where closing dialog boxes comes into play.

Closing Dialog Boxes in Angular

Closing dialog boxes in Angular can be achieved using various methods. We’ll cover three common methods: using the dialogRef, using a button, and using a keyboard shortcut.

Method 1: Using the dialogRef

The dialogRef is a reference to the dialog object that can be used to close the dialog box programmatically. Here’s an example:

import { MatDialog, MatDialogRef } from '@angular/material/dialog';

export class MyComponent {
  constructor(private dialog: MatDialog) { }

  openDialog() {
    const dialogRef = this.dialog.open(MyDialogComponent, {
      width: '250px',
      data: {}
    });

    dialogRef.afterClosed().subscribe(result => {
      console.log('Dialog closed');
    });
  }
}

In the above example, we’re using the MatDialog service to open a dialog box. The dialogRef object is returned by the open method, which can be used to close the dialog box programmatically.

Method 2: Using a Button

Another way to close a dialog box is by using a button. You can add a button to your dialog box and bind a click event to it. Here’s an example:

<button mat-button (click)="dialogRef.close()">Close</button>

In the above example, we’re using the dialogRef.close() method to close the dialog box when the button is clicked.

Method 3: Using a Keyboard Shortcut

You can also close a dialog box using a keyboard shortcut. For example, you can use the Esc key to close the dialog box. Here’s an example:

<mat-dialog-actions>
  <button mat-button (click)="dialogRef.close()">Close</button>
  </mat-dialog-actions>

<button style="display: none;" (click)="dialogRef.close()" id="close-btn"></button>

<script>
  document.addEventListener('keydown', event => {
    if (event.key === 'Escape') {
      document.getElementById('close-btn').click();
    }
  });
</script>

In the above example, we’re using JavaScript to bind the Esc key to the close button. When the Esc key is pressed, the close button is clicked programmatically, which closes the dialog box.

Closing Dialog Boxes using ng Matero

Now that we’ve covered the basics of closing dialog boxes in Angular, let’s see how to do it using ng Matero.

Method 1: Using the close method

ng Matero provides a close method that can be used to close the dialog box programmatically. Here’s an example:

<mat-matero-dialog #dialog>
  <mat-matero-dialog-header>
    <mat-matero-header>Dialog Header</mat-matero-header>
  </mat-matero-dialog-header>
  <mat-matero-dialog-content>
    <p>This is the dialog content</p>
  </mat-matero-dialog-content>
  <mat-matero-dialog-actions>
    <button mat-button (click)="dialog.close()">Close</button>
  </mat-matero-dialog-actions>
</mat-matero-dialog>

In the above example, we’re using the close method provided by ng Matero to close the dialog box when the button is clicked.

Method 2: Using the dismiss method

ng Matero also provides a dismiss method that can be used to close the dialog box programmatically. Here’s an example:

<mat-matero-dialog #dialog>
  <mat-matero-dialog-header>
    <mat-matero-header>Dialog Header</mat-matero-header>
  </mat-matero-dialog-header>
  <mat-matero-dialog-content>
    <p>This is the dialog content</p>
  </mat-matero-dialog-content>
  <mat-matero-dialog-actions>
    <button mat-button (click)="dialog.dismiss()">Dismiss</button>
  </mat-matero-dialog-actions>
</mat-matero-dialog>

In the above example, we’re using the dismiss method provided by ng Matero to close the dialog box when the button is clicked.

Conclusion

Closing dialog boxes in Angular can be achieved using various methods. ng Matero provides a set of features that make it easy to close dialog boxes programmatically. By using the dialogRef, buttons, and keyboard shortcuts, you can create a seamless user experience in your Angular application.
