Is there a way to alter the date format for input elements within formGroups using Angular 7?

When the input is of type 'Date', the date format is dd/MM/yyyy.
I need to convert the date format from MM/dd/yyyy to dd/MM/yyyy (Turkish Format and Turkish Calendar).

Below is the code snippet.

<form [formGroup]="opportunityForm" (ngSubmit)="updateData(opportunityForm.value)">
 <div class="form-group">
          <label>Creation Date</label>
          <input  type="date"  class="form-control"  formControlName="createDate" required>
          <div class="alert-danger" *ngIf="!opportunityForm.controls['createDate'].valid && (opportunityForm.controls['createDate'].touched)">
            <div [hidden]="!opportunityForm.controls['createDate'].errors.required">
              Date field is required
            </div>
          </div>
        </div>
 <button type="submit" class="btn btn-primary" [disabled]="!opportunityForm.valid">Update</button>
</form>



constructor(private http: HttpClient,private fb: FormBuilder,private router: Router,private actRoute: ActivatedRoute, private service:OpportunityService) {
    this.opportunityForm=this.fb.group({
      title:['',Validators.required],
      description:['',Validators.required],
      createDate:['',Validators.required],
      expirationDate:['',Validators.required],
      file: new FormControl(null)  
    });

Please provide suggestions and solutions. Thank you!

Answer №1

If you want to customize the 'createDate' field in your formControl, you can do so easily.

To change the date into any desired format, use the DatePipe provided by Angular.

Start by importing the DatePipe in your component's TypeScript file:

import { DatePipe } from '@angular/common';

Add the DatePipe to the providers array:

styleUrls: ['component.css'];
providers: [DatePipe] // this is how you inject pipes and services

Then declare it in the constructor:

 constructor(
    private datePipe: DatePipe
  ) { } 

You can create a function to manipulate the date and call it within the updateData(formValue), or directly manipulate the date inside the updateData(formValue) method.

// Example of date manipulation using DatePipe

const formattedDate = this.datePipe.transform(this.opportunityForm.get('createDate').value, 'dd-MM-yyyy')

Answer №2

If you're looking to change the appearance of the format in the HTML, there are various approaches you can take. However, if simplicity is your goal, I recommend using formatDate instead of datePipe. It's a much easier option in my opinion.

To implement this in your .ts file, follow these steps:

import { formatDate } from '@angular/common';
this.opportunityForm.value.createDate = formatDate(this.opportunityForm.value.createDate, 'yyyy/MM/dd', 'en');
// Replace 'yyyy/MM/dd' with your desired format

Answer №3

To resolve the problem, I utilized DatePipe to customize the format as needed on the server-side. Additionally, I adjusted the browser language so that users can view the desired date format.
