tinymask

A js mask simple like killing zombies =).

Usage

Install it from npm using npm install --save tinymask

var TinyMask = require('tinymask')
var maskInstance = TinyMask('9999-9999');
 
var result = maskInstance.mask('12345678');
 
console.log(result); //1234-5678

By default, we use this translation:

• 9 -> Accept numbers
• A -> Accept alpha
• S -> Accept alphanumerics
• * -> Accept all

Options

You can pass options for the mask. We use the defaults:

var maskInstance = TinyMask('9999-9999', {
    translation: {
        '9': function (val) {
            return val.replace(/[^0-9]+/g, '');
        },
        'A': function (val) {
            return val.replace(/[^a-zA-Z]+/g, '');
        },
        'S': function (val) {
            return val.replace(/[^a-zA-Z0-9]+/g, '');
        },
        '*': function (val) {
            return val;
        }
    },
    invalidValues: [null, undefined, '']
});

translation (Object | optional)

You can add or override any of the translation keys. Ex:

var maskInstance = TinyMask('9999-9999', {
    translation: {
        // in this case, we add new # translation that allow
        // blank spaces.
        '#': function (val) {
            if (val === ' ') {
                return val;
            }
 
            return null;
        },
        // here we override the * translation to accept only
        // some characters instead all characters.
        '*': function (val) {
            if (['*', '!', '?'].indexOf(val) >= 0) {
                return val;
            }
            return null;
        }
    }
});

invalidValues (Array | optional)

You can set ignored value. If any translation result on one of this values, that will be ignored.

var maskInstance = TinyMask('9999-9999', {
    // in this case, all null, undefined, empty string or blanck spaces returned from translation will be ignored.
    invalidValues: [null, undefined, '', ' ']
});
