What's this

It's a pure JavaScript mask input. Now you can use a simple and pure javascript lib to mask your input elements, without need to load jQuery or Zepto to do it.

Let's live a lightweight client-side world using micro libraries as VanillaMasker is! Don't worry about where this will work, because this is a cross-browser and cross-device library. And if you find any bug, please let us know about it reporting an issue.

If you wanna see how this lib works, click to test this demo page.

How to install

Download script

development version (6.2 Kbytes);
minified version (3.24 Kbytes);

Bower

You can install it via bower too, using this command: bower install --save vanilla-masker

Meteor

And you can install inside your meteor projects with this command: meteor add bankfacil:vanilla-masker

How to use

Loading the lib

Like I said, you need to download and put this lib in your own site, using this tag below:

<html>
   <head></head>
   <body>
      <input type="text">
      <!-- Loading the vanilla-masker lib -->
      <script src="vanilla-masker.min.js"></script>
   </body>
</html>

Common uses

Money format

// Masking input element to money.
VMasker(document.querySelector("data-js-input")).maskMoney();

// Masking input element to money with options.
VMasker(document.querySelector("data-js-input")).maskMoney({
  // Decimal precision -> "90"
  precision: 2,
  // Decimal separator -> ",90"
  separator: ',',
  // Number delimiter -> "12.345.678"
  delimiter: '.',
  // Money unit -> "R$ 12.345.678,90"
  unit: 'R$',
  // Money unit -> "12.345.678,90 R$"
  suffixUnit: 'R$',
  // Force type only number instead decimal,
  // masking decimals with ",00"
  // Zero cents -> "R$ 1.234.567.890,00"
  zeroCents: true
});

// Masking an array of input elements to money.
VMasker(document.querySelectorAll("data-js-input")).maskMoney();

// Converts number to money string
VMasker.toMoney(1234); // -> R$ 1.234,00

Only numbers

// Masking input element to number.
VMasker(document.querySelector("data-js-input")).maskNumber();

// Converts any string to number
VMasker.toNumber("123ac34"); // -> 12334
VMasker.toNumber("-123ac34"); // -> -12334

Custom pattern

// Listen the input element masking it to format with pattern.
VMasker(document.querySelector("input")).maskPattern("(99) 9999-9999");

// Converts value to masked phone
VMasker.toPattern(1099911111, "(99) 9999-9999"); // -> (10) 9991-1111
// Converts value to masked date
VMasker.toPattern(12122000, "99/99/9999"); // -> 12/12/2000
// Converts value to masked document
VMasker.toPattern(99911111101, "999.999.999-99"); // -> 999.111.111-01
// Converts value to masked car plate
VMasker.toPattern('ABC1234', "AAA-9999"); // -> ABC-1234
// Converts value to masked vehicle identification
VMasker.toPattern('9BGRD08X04G117974', "SS.SS.SSSSS.S.S.SSSSSS"); // -> 9B.GR.D08X0.4.G.117974

// Pass in an optional placeholder option to represent remaining characters to be entered
VMasker.toPattern('4', {pattern: "(999) 999-9999", placeholder: "x"}); // -> (4xx) xxx-xxxx

Undoing a mask

var el = document.querySelector("input")
VMasker(el).maskPattern("(99) 9999-9999"); // masking the input
VMasker(el).unMask(); // unmask!

Dynamic mask

Sometimes you need swap the mask according with value. You can see the sample below on codepen.io

function inputHandler(masks, max, event) {
  var c = event.target;
  var v = c.value.replace(/\D/g, '');
  var m = c.value.length > max ? 1 : 0;
  VMasker(c).unMask();
  VMasker(c).maskPattern(masks[m]);
  c.value = VMasker.toPattern(v, masks[m]);
}

var telMask = ['(99) 9999-99999', '(99) 99999-9999'];
var tel = document.querySelector('#tel');
VMasker(tel).maskPattern(telMask[0]);
tel.addEventListener('input', inputHandler.bind(undefined, telMask, 14), false);

var docMask = ['999.999.999-999', '99.999.999/9999-99'];
var doc = document.querySelector('#doc');
VMasker(doc).maskPattern(docMask[0]);
doc.addEventListener('input', inputHandler.bind(undefined, docMask, 14), false);

Meteor uses

If your app is built on top of Meteor framework, you can use the lib in this way...

<body>
  <h1>Welcome to Meteor!</h1>
  {{> myTemplate}}
</body>

<template name="myTemplate">
  <input type="text" placeholder="Money" data-vm-mask-money>
  <input type="text" placeholder="Number" data-vm-mask-number>
  <input type="text" placeholder="Date" data-vm-mask-date>
</template>

You just need to bind the elements into the template rendered function...

if (Meteor.isClient) {
  Template.myTemplate.rendered = function() {
    VMasker(this.find("[data-vm-mask-money]")).maskMoney();
    VMasker(this.find("[data-vm-mask-number]")).maskNumber();
    VMasker(this.find("[data-vm-mask-date]")).maskPattern("99/99/9999");
  };
}
