How to Add a “Today” Button to Angular Material Datepicker and Handle Date Changes?

Are you tired of scrolling through the calendar to select today’s date in your Angular Material Datepicker? Do you want to provide a convenient way for your users to quickly select the current date? Well, you’re in luck! In this article, we’ll show you how to add a “Today” button to your Angular Material Datepicker and handle date changes like a pro.

Step 1: Setting Up the Angular Material Datepicker

Before we dive into adding the “Today” button, let’s make sure we have the Angular Material Datepicker set up correctly. If you’re new to Angular Material, you can follow these steps to get started:

• Install Angular Material using the following command: ng add @angular/material
• Import the necessary modules in your component module:

  import { MatDatepickerModule } from '@angular/material/datepicker';
  import { MatInputModule } from '@angular/material/input';
  
  @NgModule({
    imports: [MatDatepickerModule, MatInputModule],
    ...
  })
  export class AppModule {}
  

• Add the datepicker component to your HTML template:

  <input matInput [matDatepicker]="picker">
  <mat-datepicker #picker></mat-datepicker>
  

Step 2: Adding the “Today” Button

Now that we have the datepicker set up, let’s add the “Today” button. We’ll create a custom button that will set the date to today’s date when clicked.

<button mat-button (click)="selectToday()">Today</button>
<input matInput [matDatepicker]="picker">
<mat-datepicker #picker></mat-datepicker>

In our component, we’ll add a method to handle the click event:

import { Component } from '@angular/core';
import { MatDatepicker } from '@angular/material/datepicker';

@Component({
  selector: 'app-datepicker-example',
  templateUrl: './datepicker-example.html',
  styleUrls: ['./datepicker-example.css']
})
export class DatepickerExampleComponent {
  constructor(private picker: MatDatepicker) { }

  selectToday(): void {
    this.picker.select(new Date());
  }
}

Step 3: Handling Date Changes

Now that we have the “Today” button working, let’s handle date changes. We’ll use the `(dateChange)` event emitted by the datepicker to detect when the user selects a new date.

<input matInput [matDatepicker]="picker" (dateChange)="handleDateChange($event)">
<mat-datepicker #picker></mat-datepicker>

In our component, we’ll add a method to handle the date change event:

import { Component } from '@angular/core';
import { MatDatepicker } from '@angular/material/datepicker';

@Component({
  selector: 'app-datepicker-example',
  templateUrl: './datepicker-example.html',
  styleUrls: ['./datepicker-example.css']
})
export class DatepickerExampleComponent {
  constructor(private picker: MatDatepicker) { }

  selectToday(): void {
    this.picker.select(new Date());
  }

  handleDateChange(event: MatDatepickerDateChange): void {
    console.log('Date changed to:', event.value);
    // Perform any additional logic here, such as updating a database or sending a request
  }
}

Step 4: Customizing the “Today” Button

Now that we have the “Today” button working, let’s customize it to fit our application’s style. We can add icons, change the text, or even use a custom template.

<button mat-button [mattooltip]="todayTooltip" (click)="selectToday()">
  <mat-icon>today</mat-icon> Today
</button>

In our component, we’ll add a property for the tooltip:

import { Component } from '@angular/core';
import { MatDatepicker } from '@angular/material/datepicker';

@Component({
  selector: 'app-datepicker-example',
  templateUrl: './datepicker-example.html',
  styleUrls: ['./datepicker-example.css']
})
export class DatepickerExampleComponent {
  todayTooltip = 'Select today\'s date';

  constructor(private picker: MatDatepicker) { }

  selectToday(): void {
    this.picker.select(new Date());
  }

  handleDateChange(event: MatDatepickerDateChange): void {
    console.log('Date changed to:', event.value);
    // Perform any additional logic here, such as updating a database or sending a request
  }
}

Conclusion

In this article, we’ve shown you how to add a “Today” button to your Angular Material Datepicker and handle date changes. By following these steps, you can provide a convenient way for your users to quickly select the current date and handle date changes with ease.

Tips and Variations

Here are some additional tips and variations to consider:

• Use a custom template for the “Today” button to match your application’s style.
• Add a keyboard shortcut to select today’s date, such as pressing the “T” key.
• Use the `(dateInput)` event to handle manual date inputs, such as when the user types a date instead of selecting it from the calendar.
• Implement a custom date range validator to restrict the date range to a specific period, such as a week or a month.

Event	Description
(dateChange)	Emitted when the user selects a new date from the calendar.
(dateInput)	Emitted when the user manually inputs a date, such as by typing it.
(opened)	Emitted when the datepicker is opened.
(closed)	Emitted when the datepicker is closed.

By using the Angular Material Datepicker and handling date changes correctly, you can create a seamless and user-friendly experience for your users. Happy coding!
