ui-mask

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

Requirements

• AngularJS

Usage

Bower

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, ...]);

Customizing

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 five 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']
• addDefaultPlaceholder - default: true
• escChar - default: '\\'
• allowInvalidValue - default: false

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

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.

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.

If the escChar (\ by default) is encountered in a mask, the next character will be treated as a literal and not a mask definition key. To disable the escChar feature completely, set escChar to null.

When allowInvalidValue is set to true, apply value to $modelValue even if it isn't valid. By default, if you write an invalid value, the model will stay undefined.

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]/});
  uiMaskConfigProvider.clearOnBlur(false);
  uiMaskConfigProvider.eventsToHandle(['input', 'keyup', 'click']);
}

maskDefinitions

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.

modelViewValue

If this is set to true, then the model value bound with ng-model will be the same as the $viewValue meaning it will contain any static mask characters present in the mask definition. This will not set the model value to a $viewValue that is considered invalid.

uiMaskPlaceholder

Allows customizing the mask placeholder when a user has focused the input element and while typing in their value

uiMaskPlaceholderChar

Allows customizing the mask placeholder character. The default mask placeholder is _.

Set this attribute to the word space if you want the placeholder character to be whitespace.

addDefaultPlaceholder

The default placeholder is constructed from the ui-mask definition so a mask of 999-9999 would have a default placeholder of ___-____; unless you have overridden the default placeholder character.

Testing

Most of the testing is done using Karma to run the tests and SauceLabs to provide the different browser environments to test against.

Mobile testing and debugging uses BrowserStack for its abilities to remotely debug mobile devices from a browser.

Development

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
gulp

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.
