# What's this
[](https://travis-ci.org/vanilla-masker/vanilla-masker)
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](https://github.com/vanilla-masker/vanilla-masker/issues).
If you wanna see how this lib works, click to test this [demo page](http://fleury.io/vanilla-masker/demo.html).

# 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
```
### Common uses
#### Money format
``` javascript
// 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
``` javascript
// 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
``` javascript
// 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
``` javascript
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](http://codepen.io/lagden/pen/meemqG)
```javascript
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...
