Current behavior

Now InputMask is not possible to be used in calendar input.

Expected behavior

Will be great if calendar will have option that will allow to use InputMask based on the dateFormat option.

What is the motivation / use case for changing the behavior?

That feature will improve user experience when he inputs data from the keyboard.

[yfain]

After this issue will be resolved, we'll consider switching from Wijmo to PrimeNG. As of now we use both.

[Da13Harris]

In our enterprise environment, we currently use another third-party mask plugin (angular2-text-mask) in tandem with the PrimeNG calendar control. While we've managed to make this work, the solution is not ideal and often introduces bugs that are difficult to resolve.

An option on the PrimeNG calendar to apply an input mask would be much appreciated. It might be even more ideal if the PrimeNG input mask was just a dynamic directive that could be applied to either native inputs or other PrimeNG components, including the calendar/datepicker.

@Da13Harris I added a issue that describe your request. Change InputMask component to a directive

[vinothbabu]

Is this planned for any release?

[thenninger]

I'm already getting negative feedback from my company about the calendars' lack of an input mask. Please add this feature!

[UlricW]

Is it possible to have a feedback to know if this "new feature" is planned or not ? cause it's an important feature for a lot of people..

[icarodebarros]

I did a paleative solution without a third-party mask plugin using the event the component send. My code is fresh, so it needs to be worked out. I did the algoritm by intercepting the input element (event.path[0]):

<p-calendar
    ...
    dateFormat="dd/mm/yy"
    (onInput)="onInputDate($event)" (onBlur)="onBlurDate()"
    placeholder="dd/mm/aaaa" [locale]="ptBR"
    ...
></p-calendar>

    onInputDate(event): void {
        let cursorPosition = event.path[0].selectionEnd;

        if (event.inputType === 'deleteContentBackward' && (cursorPosition === 2 || cursorPosition === 5)) {
            event.path[0].value = event.path[0].value.substring(0, cursorPosition - 1) + event.path[0].value.substring(cursorPosition);
            cursorPosition --;
        }
        if (event.inputType === 'insertText' && (event.path[0].value.length > 10)) {
            event.path[0].value = event.path[0].value.substring(0, event.path[0].value.length - 1);
        }

        this.dateMask = event.path[0].value.toString();
        this.dateMask = this.dateMask.replace(/\D/g, '');

        let mask = '';
        for (let i = 0; i < this.dateMask.length; i++) {
            mask += this.dateMask[i];
            if (i === 1 || i === 3) {
                mask += '/';
                if (cursorPosition === 2 || cursorPosition === 5) { cursorPosition++; }
            }
        }
        event.path[0].value = mask.toString();
        event.path[0].selectionStart = cursorPosition;
        event.path[0].selectionEnd = cursorPosition;

        if (event.path[0].value.length === 10) {
            const dt = this.stringToDate(event.path[0].value);
            if (this.isValidDate(dt)) {
                this.value = dt;
            }
        }
    }

    onBlurDate(): void {
        if (!!this.value && !this.isValidDate(this.value)) {
            this.value = null;
        }
    }

I know that is not a good looking solution, but maybe it could help some one.

@icarodebarros This did help me - I just had to change event.path[0] to event.target because only Chrome supports path currently as it is not standard. I also did not need to use the blur event.

[ghost]

Any news about this?

[mikaelboff]

Nothing about this yet??

[tayloraharry]

this is so annoying. should be a standard.

[edumrodrigues]

I'm missing this feature. It really needs to be standard.

[shogogan]

found out why it's so hard to set a calendar mask. got to build a directive based on the inputMask to use on the pCalendar. One of the main problems to solve this problem is the DateFormat options, and the possible functionalities(range, multiple and whatsoever functionality). If set just for numeric values. the mask can be pretty simple to make.

[leonetosoft]

Many users find it impractical to have to select a date in the calendar, they want to type on the keyboard when using the mouse, and this is really true. I think it would be a question of usability to think (@cagataycivici), for now I have created a method to use the inputMask with the validation of the user input:

Component:

import { Component, OnInit, Input, forwardRef, ChangeDetectorRef, Output, EventEmitter, Directive } from '@angular/core';
import { NG_VALUE_ACCESSOR, ControlValueAccessor, NG_VALIDATORS, Validator, AbstractControl } from '@angular/forms';
import * as moment from 'moment';

export const LNDATE_VALUE_ACCESSOR: any = {
  provide: NG_VALUE_ACCESSOR,
  useExisting: forwardRef(() => AppLnDateComponent),
  multi: true
};

@Component({
  selector: 'app-app-ln-date',
  templateUrl: './app-ln-date.component.html',
  styleUrls: ['./app-ln-date.component.css'],
  providers: [LNDATE_VALUE_ACCESSOR]
})
export class AppLnDateComponent implements OnInit, ControlValueAccessor {
  @Input()
  mask = '99/99/9999';
  @Input()
  inputMask = 'YYYY-MM-DD';
  @Input()
  displayMask = 'DD/MM/YYYY';

  @Output() onChange: EventEmitter<any> = new EventEmitter();
  @Input() disabled: boolean;
  @Input() url: boolean;
  onModelChange: Function = () => { };

  onModelTouched: Function = () => { };
  focused: boolean = false;
  value: string;
  valueAcessor: string;
  keySelected: number;

  completed = false;

  constructor(private cd: ChangeDetectorRef) { }

  ngOnInit() {
  }

  writeValue(obj: any): void {
    if (obj && !moment(obj, this.inputMask, true).isValid()) {
      throw new Error(`Data inválida deve estar no formato correto, ${obj}`);
    }
    this.value = moment(obj).format(this.inputMask);
    this.valueAcessor = moment(this.value, this.inputMask).format(this.displayMask);
    this.cd.markForCheck();
  }

  registerOnChange(fn: any): void {
    this.onModelChange = fn;
  }

  registerOnTouched(fn: any): void {
    this.onModelTouched = fn;
  }

  setDisabledState?(val: boolean): void {
    this.disabled = val;
  }

  onFocus(event: Event) {
    this.focused = true;
  }

  onBlur(event: Event) {
    this.focused = false;
    if(!this.isValidDate()) {
     /* this.valueAcessor = moment(this.value, this.inputMask).format(this.displayMask);*/
     setTimeout(() => { 
     /*  this.valueAcessor = moment(this.value, this.inputMask).format(this.displayMask);*/
     this.valueAcessor = '';
     this.value = undefined;
     this.updateModel(event, undefined);
     }, 100);
    }
  }

  isValidDate() {
    return moment(this.valueAcessor, this.displayMask, true).isValid();
  }

  onIputKey(evt) {
    this.value = evt;
    this.updateModel(evt, String(this.value));
  }

  onInputChange() {
    //console.log('digito');

    // let val = (<HTMLInputElement>event.target).value;
    let setVal = moment(this.valueAcessor, this.displayMask).format(this.inputMask);
    if (setVal !== 'Invalid date') {
      this.updateModel(event, setVal);
    }
  }

  onInput(event: KeyboardEvent) {
    this.value = (<HTMLInputElement>event.target).value;
    this.onModelChange(this.value);
  }

  updateModel(event: Event, value: string) {
    this.value = value;
    this.onModelChange(this.value);
    this.onChange.emit({
      originalEvent: event,
      value: value
    });
  }


}

@Directive({
  selector: '[appCheckDate]',
  providers: [{ provide: NG_VALIDATORS, useExisting: DateValidatorDirective, multi: true }]
})
export class DateValidatorDirective implements Validator {
  @Input('dateValue') dateValue: string;
  @Input('dateFormat') dateFormat: string;

  validate(control: AbstractControl): { [key: string]: any } | null {
    return this.dateValue && moment(control.value, this.dateFormat, true).isValid() ?
      null : {
        invalidDate: {
          valid: false
        }
      };
  }
}

HTML:

<p-inputMask [mask]="mask" (onFocus)="onFocus($event)" (onBlur)="onBlur($event)" appCheckDate (onComplete)="onInputChange()" [dateValue]="valueAcessor" [(ngModel)]="valueAcessor" [dateFormat]="displayMask" placeholder="DD/MM/YYYYY"></p-inputMask>

IN FORM OR USE NGMODULE:

<app-app-ln-date mask="99/99/9999" inputMask="YYYY-MM-DD" displayMask="DD/MM/YYYY" formControlName="data_internacao"></app-app-ln-date>

obs: use moment.js to format and valid dates ...

I've made one lib for masking, one of the first things that i built was a directive for primeng calendar. https://www.npmjs.com/package/racoon-mask

it's quite simple and solve most of the directive problems, if anyone find anything that could improve it, this is the github link :)

https://github.com/shogogan/racoon-mask

it has two directives, but the main one here is the [rPCalendarMask], no inputs, no outputs, it just gets the dateformat and builds a mask on it (with time included if wanted)

usage: HTML: <p-calendar rPCalendarMask></p-calendar>

[shogogan]

Just informing that i changed the mask lib name (racoon-lib to racoon-mask). And now it can show the placeholder like __/__/____

and it is working pretty better (with a early stage of a showcase to try on while testing)

And I put it on version 1.0.0 right now. 😄

still needs some improvements, but by now it's working on android/ios chrome/ie10

Any issue just report or open a PR :)

Thank you so much for your work. I'm using the rPCalendarMask directive but cannot get __/__/____ to show while the user is inputting the date.

As this sample shows for phone number, when the user selects the input, I would like for the __/__/____ to be in place of ___-___-____, but for p-calendar element.

I'm using racoon-mask-primeng version 1.1.11. It would be very helpful if you can create a demo of this.

Thank you again.

[shogogan]

Hey @iwashungry1992, to show the placeholder, just set [showPlaceholder]="true" it should work correctly then, it will pick the dateformat informed on the p-calendar and set the placeholder accordingly.

If not then it may be a bug, and i need to fix it

This made it work, thank you!

[iwashungry1992]

@shogogan One thing I noticed that may be a bug - when the user deletes, they can only delete to the closest "/". Then they cannot delete anymore unless they move the mouse cursor manually into the next set of "/". Also, when this happens, the placement of the cursor isn't in the correct spot.

See below:

Just another workaround suggestion...

It seems it is possible to use Cleave alongside the Calendar component.

After

npm i --save cleave.js @types/cleave.js

you can configure your component something like this:

import Cleave from 'cleave.js';
import { Calendar } from 'primeng/calendar';

@ViewChild('calendarDataInicio')
calendarDataInicio: Calendar;

cleaveDataInicio: Cleave;

ngAfterViewInit() {
  this.cleaveDataInicio = new Cleave(this.calendarDataInicio.inputfieldViewChild.nativeElement,
    {
      date: true,
      datePattern: ['d', 'm', 'Y'],
    }
  );
}

Any official solution? Or official response from primeng?
