    Apply a mask on an input field so the user can only type pre-determined pattern.


    • AngularJS



    You can get it from Bower

    bower install angular-ui-mask

    Load the script files in your application:

    <script type="text/javascript" src="bower_components/angular/angular.js"></script>
    <script type="text/javascript" src="bower_components/angular-ui-mask/dist/mask.js"></script>

    Add the specific module to your dependencies:

    angular.module('myApp', ['ui.mask', ...])

    NPM (CommonJS, ES6 module)

    Also you can use it as CommonJS or ES6 module with any build system that supports those type of modules (Webpack, SystemJS, JSPM etc):

    npm install angular-ui-mask

    And then include it with

    // CommonJS
    var uiMask = require('angular-ui-mask');
    angular.module('myApp', [uiMask, ...]);
    // ES6 module
    import uiMask from 'angular-ui-mask';
    angular.module('myApp', [uiMask, ...]);


    You can customize several behaviors of ui-mask by taking advantage of the ui-options object. Declare ui-options as an additional attribute on the same element where you declare ui-mask.

    Inside of ui-options, you can customize these four properties:

    • maskDefinitions - default: { '9': /\d/, 'A': /[a-zA-Z]/, '*': /[a-zA-Z0-9]/ },
    • clearOnBlur - default: true,
    • clearOnBlurPlaceholder - default: false,
    • eventsToHandle - default: ['input', 'keyup', 'click', 'focus']

    When customizing eventsToHandle or clearOnBlur, the value you supply will replace the default. To customize eventsToHandle, be sure to replace the entire array.

    When setting clearOnBlurPlaceholder to true, it will show the placeholder text instead of the empty mask. It requires the ui-mask-placeholder attribute to be set on the input to display properly.

    Whereas, maskDefinitions is an object, so any custom object you supply will be merged together with the defaults using angular.extend(). This allows you to override the defaults selectively, if you wish.

    Global customization

    In addition to customizing behaviors for a specific element, you can also customize the behaviors globally. To do this, simply use the uiMaskConfig provider in your app configuration. Example:

    app.config(['uiMask.ConfigProvider', function(uiMaskConfigProvider) {
      uiMaskConfigProvider.maskDefinitions({'A': /[a-z], '*': /[a-zA-Z0-9]/});


    The keys in maskDefinitions represent the special tokens/characters used in your mask declaration to delimit acceptable ranges of inputs. For example, we use '9' here to accept any numeric values for a phone number: ui-mask="(999) 999-9999". The values associated with each token are regexen. Each regex defines the ranges of values that will be acceptable as inputs in the position of that token.


    We use Karma and jshint to ensure the quality of the code. The easiest way to run these checks is to use gulp:

    npm install -g gulp-cli
    npm install && bower install

    The karma task will try to open Firefox and Chrome as browser in which to run the tests. Make sure this is available or change the configuration in karma.conf.js

    Gulp watch

    gulp watch will automatically test your code and build a release whenever source files change.

    How to release

    Use gulp to bump version, build and create a tag. Then push to GitHub:

    gulp release [--patch|--minor|--major]
    git push --tags origin master # push everything to GitHub 

    Travis will take care of testing and publishing to npm's registry (bower will pick up the change automatically). Finally create a release on GitHub from the tag created by Travis.
