Simple input mask for AngularJS. Demo

With Bower:

bower install --save ng-blackmask

1. Include the module blackMask in your angular app.

2. Include the directive bm-numbers-mask with max-length param in your form:

<input type="text" name="field" ng-model="field" bm-numbers-mask max-length="9">

3. You can set the placeholder character (the default is _):

<input type="text" name="field" ng-model="field" bm-numbers-mask max-length="9" placeholder="*">

IE8+, Chrome, Firefox, iOS 7 Safari/Chrome. Unfortunately Android browsers don't work with this mask correctly so be careful if you want to support them
