Mask

Create your masks easily

Mask comes with three basic implementations MaskDefault, MaskNumber and MaskDate, but you can use MaskCore to do your own masks implementation easily.

Quick start

Choose your favorite option below:

Install with NPM

npm i @ionited/mask

Get from UNPKG

https://unpkg.com/@ionited/mask@latest/dist/mask.js

---

Usage

To basic usage you can simply call:

Mask(document.querySelector('#input1'), { mask: '(99) 9999-9999' }); // To use MaskDefault
Mask(document.querySelector('#input2'), { number: true }); // To use MaskNumber
Mask(document.querySelector('#input3'), { date: 'DD/MM/YYYY' }); // To use MaskDate

MaskDefault

A mask that receives a regex or a string with numbers, letters or other symbols

Mask(el: HTMLElement, { mask: RegExp | string | MaskDefaultOptions });

interface MaskDefaultOptions {
  allowEmpty?: boolean;
  mask: RegExp | string;
}

Symbol	Pattern	Description
9	/^[0-9]$/	Only numbers
A	/^[A-Za-zÀ-ÿ]$/	Only letters

Any other symbol is fixed.

MaskNumber

A mask for monetary and decimal values

Mask(el: HTMLElement, { number: true | MaskNumberOptions });

interface MaskNumberOptions {
  allowEmpty: boolean;
  allowNegative: boolean;
  decimal: number;
  decimalPoint: string;
  end: boolean;
  prefix: string;
  suffix: string;
  thousandPoint: string;
}

MaskDate

A mask for date and time values

Mask(el: HTMLElement, { date: string | MaskDateOptions });

interface MaskDateOptions {
  format: string;
  placeholders: { [key: string]: string };
}

Format	Pattern	Description
YYYY	0000-∞	Year
MM	01-12	Month
DD	01-31	Day
hh	00-23	Hour
mm	00-59	Minutes
ss	00-59	Seconds

Any other symbol is fixed.

MaskCore

You can create your own mask logic easily, you only need register a mask and use:

Mask.register(name: string, mask: any): void;

The recommended way to do a new mask is writing a class that extends MaskOptions

interface MaskOptions {
  instance: MaskCore;
  init?(data: MaskData): void;
  input?(data: MaskData): void;
  format(data: MaskData): void;
  focus?(data: MaskData): void;
  blur?(data: MaskData): void;
  mouseover?(data: MaskData): void;
  mouseout?(data: MaskData): void;
}

interface MaskData {
  cursorPosition: number;
  delete: boolean;
  focus: boolean;
  input: string;
  output: string;
  outputRaw: any;
}

MyMask example (only accept numbers):

import { MaskData, MaskCore, MaskOptions } from '@ionited/mask/core';

export class MyMask implements MaskOptions {
  instance: MaskCore;

  constructor(el: HTMLInputElement) {
    this.instance = new MaskCore(el, this);
  }

  init(data: MaskData) {
    this.format(data);
  }

  format(data: MaskData) {
    data.output = data.input.replace(/[^0-9]/g, ''); 
  }
}

Register and use:

Mask.register('myMask', MyMask); // Register

Mask(document.querySelector('#myMask'), { myMask: true }); // Enjoy your own mask!
