Callback Examples

var options =  { 
  onComplete: function(cep) {
    alert('CEP Completed!:' + cep);
  },
  onKeyPress: function(cep, event, currentField, options){
    console.log('An key was pressed!:', cep, ' event: ', event, 
                'currentField: ', currentField, ' options: ', options);
  },
  onChange: function(cep){
    console.log('cep changed! ', cep);
  }
};

$('.cep_with_callback').mask('00000-000', options);

On-the-fly mask change

var options =  {onKeyPress: function(cep){
  var masks = ['00000-000', '0-00-00-00'];
    mask = (cep.length>7) ? masks[1] : masks[0];
  $('.crazy_cep').mask(mask, this);
}};

$('.crazy_cep').mask('00000-000', options);

Mask as a function

var celphoneMask = function(phone, e, currentField, options){
  return phone.match(/^(\(?11\)? ?9(5[0-9]|6[0-9]|7[01234569]|8[0-9]|9[0-9])[0-9]{1})/g) ? 
  '(00) 00000-0000' : '(00) 0000-0000';
};

$(".sp_celphones").mask(celphoneMask);

Using HTML Notation Exemples

To get your mask applied with the data-mask attribute just use it as the same way you use with the $.mask function.

<input type="text" name="field-name" data-mask="00/00/0000" />

Activating a reversible mask

<input type="text" name="field-name" data-mask="00/00/0000" data-mask-reverse="true" />

Disabling automatic maxlength

<input type="text" name="field-name" data-mask="00/00/0000" data-mask-maxlength="false" />

Using clearIfNotMatch option

<input type="text" name="field-name" data-mask="00/00/0000" data-mask-clearifnotmatch="true" />

Customization

jQuery Mask Plugin has a few default options that you can overwrite as you like:

var custom_options = {
  byPassKeys: [8, 9, 37, 38, 39, 40],
  translation: {
                '0': {pattern: /\d/}, 
                '9': {pattern: /\d/, optional: true}, 
                '#': {pattern: /\d/, recursive: true}, 
                'A': {pattern: /[a-zA-Z0-9]/}, 
                'S': {pattern: /[a-zA-Z]/}
            };
};

byPassKeys list of keyboard's keyCode that you want to be ignored when it was pressed.
translation object with all digits that should be interpreted as a special chars and its regex representation.

Translation

Teach to jQuery Mask Plugin how to apply your mask:

// now the digit 0 on your mask pattern will be interpreted 
// as valid characters like 0,1,2,3,4,5,6,7,8,9 and *
$('.your-field').mask('00/00/0000', {'translation': {0: {pattern: /[0-9*]/}}});

By default, jQuery Mask Plugin only reconizes the logical digit A (Numbers and Letters) and S (A-Za-z) but you can extend or modify this behaviour by telling to jQuery Mask Plugin how to interpret those logical digits.

$('.your-field').mask('AA/SS/YYYY', {'translation': {
                                        A: {pattern: /[A-Za-z0-9]/}, 
                                        S: {pattern: /[A-Za-z]/},  
                                        Y: {pattern: /[0-9]/}
                                      }
                                });

Now jQuery Mask Plugin knows the logic digit Y and you can create your own pattern.

Optional digits

You can also tell to jQuery Mask which digit is optional, to create a IP mask for example:

// way 1
$('.ip_address').mask('099.099.099.099');
// way 2
$('.ip_address').mask('0ZZ.0ZZ.0ZZ.0ZZ', {translation:  {'Z': {pattern: /[0-9]/, optional: true}}});

Now, all Z digits in your masks is optional.

Recursive digits

With jQuery Mask Plugin you can also define recursive patterns inside your mask:

$('.money_example').mask('#.##0,00', {reverse: true});

With example above the mask will be placed from the right to the left (that's why reverse:true is defined). As soon as you start typing, a "0,00" will be applied followed by repeating recursively the following pattern "#.##". The result could be something like: 1.234.567,890.

You can also use that kind of feature to define what kind of data could be typed inside of a field:

$('.example').mask('0#');

Now only numbers will be allowed inside your form field and no maxlength will be set.

Removing the mask

$('.date').unmask();

Getting the unmasked typed value

$('.date').cleanVal();

Default Mask Legend

• 0: Only Numbers.
• 9: Only Numbers but optional.
• #: Only Numbers but recusive.
• A: Numbers and Letters.
• S: Only A-Z and a-z characters.
