Answer 1

Here is the way I created ssn directive which checks for the the pattern and I have used RobinHerbots jquery.inputmask

angular.module('SocialSecurityNumberDirective', [])
       .directive('socialSecurityNumber', socialSecurityNumber);

function socialSecurityNumber() {
    var jquery = require('jquery');
    var inputmask = require("jquery.inputmask");
    return {
        require: 'ngModel',
        restrict: 'A',
        priority: 1000,
        link: function(scope,element, attr, ctrl) {

            var jquery_element = jquery(element);
            jquery_element.inputmask({mask:"***-**-****",autoUnmask:true});
            jquery_element.on('keyup paste focus blur', function() {
                var val = element.val();    
                ctrl.$setViewValue(val);
                ctrl.$render();

             });

            var pattern = /^\d{9}$/;

            var newValue = null;

            ctrl.$validators.ssnDigits = function(value) {
                 newValue = element.val();
                return newValue === '' ? true : pattern.test(newValue);    
            };
        }
    };
}

You also can check input mask formatter.

This is a directive and it's called ui-mask and also it's a part of angular-ui.utils library.

Here is working: Live example

For the time of writing this post there aren't any examples of using this directive, so I've made a very simple example to demonstrate how this thing works in practice.

I also found that JQuery plugin that is easy to include in your Angular App (also with bower :D ) and which check all possible country codes with their respective masks : intl-tel-input

You can then use the validationScript option in order to check the validity of the input's value.

Answer 4

Inject 'xeditable' module in your angular app(freely available):

var App = angular.module('App', ['xeditable']);

And then use its built in feature in your HTML code as follows:

<div>{{ value|number:2 }}</div>

Also, if you need to format telephone number on output only, you can use a custom filter like this one:

angular.module('ng').filter('tel', function () {
    return function (tel) {
        if (!tel) { return ''; }

        var value = tel.toString().trim().replace(/^\+/, '');

        if (value.match(/[^0-9]/)) {
            return tel;
        }

        var country, city, number;

        switch (value.length) {
            case 10: // +1PPP####### -> C (PPP) ###-####
                country = 1;
                city = value.slice(0, 3);
                number = value.slice(3);
                break;

            case 11: // +CPPP####### -> CCC (PP) ###-####
                country = value[0];
                city = value.slice(1, 4);
                number = value.slice(4);
                break;

            case 12: // +CCCPP####### -> CCC (PP) ###-####
                country = value.slice(0, 3);
                city = value.slice(3, 5);
                number = value.slice(5);
                break;

            default:
                return tel;
        }

        if (country == 1) {
            country = "";
        }

        number = number.slice(0, 3) + '-' + number.slice(3);

        return (country + " (" + city + ") " + number).trim();
    };
});

Then you can use this filter in your template:

{{ phoneNumber | tel }}
<span ng-bind="phoneNumber | tel"></span>

You can use ng-pattern which is more easy and more light. http://tutorialzine.com/2014/12/learn-regular-expressions-in-20-minutes/. Here u can know about it,,,just some meaningful words,,,not needs any directive or filter,,,,
