Description:

MaskerJS is a Pure JavaScript input mask library which can be used to force user met a custom pattern into input fields.

How to use it:

Download and put the MaskerJS library right before the closing body tag.

<script src="src/masker.js"></script>

Create a new Masker object and add your own mask patterns.

var myMask = new Masker(
    [

      '(___) ___-____',
      '+_-___-___-____',  
    ]
);

You can also apply the filters as the second parameter to the Masker object.

var myMask = new Masker(
    [
      '___-____',     
      '(___) ___-____',
      '+_-___-___-____',  
    ],
    /^[0-9]$/ // allowed chars
);

Apply the Masker to a specific input field.

var myInput = document.getElementById('input');
telMask.bind(telInput);
