Answer 1

I modified the code to output phone in this format Value: +38 (095) 411-22-23 Here you can check it enter link description here

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

myApp.controller('MyCtrl', function($scope) {
  $scope.currencyVal;
});

myApp.directive('phoneInput', function($filter, $browser) {
    return {
        require: 'ngModel',
        link: function($scope, $element, $attrs, ngModelCtrl) {
            var listener = function() {
                var value = $element.val().replace(/[^0-9]/g, '');
                $element.val($filter('tel')(value, false));
            };

            // This runs when we update the text field
            ngModelCtrl.$parsers.push(function(viewValue) {
                return viewValue.replace(/[^0-9]/g, '').slice(0,12);
            });

            // This runs when the model gets updated on the scope directly and keeps our view in sync
            ngModelCtrl.$render = function() {
                $element.val($filter('tel')(ngModelCtrl.$viewValue, false));
            };

            $element.bind('change', listener);
            $element.bind('keydown', function(event) {
                var key = event.keyCode;
                // If the keys include the CTRL, SHIFT, ALT, or META keys, or the arrow keys, do nothing.
                // This lets us support copy and paste too
                if (key == 91 || (15 < key && key < 19) || (37 <= key && key <= 40)){
                    return;
                }
                $browser.defer(listener); // Have to do this or changes don't get picked up properly
            });

            $element.bind('paste cut', function() {
                $browser.defer(listener);
            });
        }

    };
});
myApp.filter('tel', function () {
    return function (tel) {
        console.log(tel);
        if (!tel) { return ''; }

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

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

        var country, city, num1, num2, num3;

        switch (value.length) {
            case 1:
            case 2:
            case 3:
                city = value;
                break;

            default:
                country = value.slice(0, 2);
                city = value.slice(2, 5);
                num1 = value.slice(5,8);
                num2 = value.slice(8,10);
                num3 = value.slice(10,12);            
        }

        if(country && city && num1 && num2 && num3){
            return ("+" + country+" (" + city + ") " + num1 +"-" + num2 + "-" + num3).trim();
        }
        else if(country && city && num1 && num2) {
            return ("+" + country+" (" + city + ") " + num1 +"-" + num2).trim();
        }else if(country && city && num1) {
            return ("+" + country+" (" + city + ") " + num1).trim();
        }else if(country && city) {
            return ("+" + country+" (" + city ).trim();
        }else if(country ) {
            return ("+" + country).trim();
        }

    };
});

I created an AngularJS module to handle this issue regarding phonenumbers for myself with a custom directive and accompanying filter.

jsfiddle example: http://jsfiddle.net/aberke/s0xpkgmq/

Filter use example: <p>{{ phonenumberValue | phonenumber }}</p>

Filter code:

.filter('phonenumber', function() {
    /* 
    Format phonenumber as: c (xxx) xxx-xxxx
        or as close as possible if phonenumber length is not 10
        if c is not '1' (country code not USA), does not use country code
    */

    return function (number) {
        /* 
        @param {Number | String} number - Number that will be formatted as telephone number
        Returns formatted number: (###) ###-####
            if number.length < 4: ###
            else if number.length < 7: (###) ###

        Does not handle country codes that are not '1' (USA)
        */
        if (!number) { return ''; }

        number = String(number);

        // Will return formattedNumber. 
        // If phonenumber isn't longer than an area code, just show number
        var formattedNumber = number;

        // if the first character is '1', strip it out and add it back
        var c = (number[0] == '1') ? '1 ' : '';
        number = number[0] == '1' ? number.slice(1) : number;

        // # (###) ###-#### as c (area) front-end
        var area = number.substring(0,3);
        var front = number.substring(3, 6);
        var end = number.substring(6, 10);

        if (front) {
            formattedNumber = (c + "(" + area + ") " + front);  
        }
        if (end) {
            formattedNumber += ("-" + end);
        }
        return formattedNumber;
    };
});

Directive use example:

<phonenumber-directive placeholder="'Input phonenumber here'" model='myModel.phonenumber'></phonenumber-directive>

Directive code:

.directive('phonenumberDirective', ['$filter', function($filter) {
    /*
    Intended use:
        <phonenumber-directive placeholder='prompt' model='someModel.phonenumber'></phonenumber-directive>
    Where:
        someModel.phonenumber: {String} value which to bind only the numeric characters [0-9] entered
            ie, if user enters 617-2223333, value of 6172223333 will be bound to model
        prompt: {String} text to keep in placeholder when no numeric input entered
    */

    function link(scope, element, attributes) {

        // scope.inputValue is the value of input element used in template
        scope.inputValue = scope.phonenumberModel;

        scope.$watch('inputValue', function(value, oldValue) {

            value = String(value);
            var number = value.replace(/[^0-9]+/g, '');
            scope.phonenumberModel = number;
            scope.inputValue = $filter('phonenumber')(number);
        });
    }

    return {
        link: link,
        restrict: 'E',
        scope: {
            phonenumberPlaceholder: '=placeholder',
            phonenumberModel: '=model',
        },
        // templateUrl: '/static/phonenumberModule/template.html',
        template: '<input ng-model="inputValue" type="tel" class="phonenumber" placeholder="{{phonenumberPlaceholder}}" title="Phonenumber (Format: (999) 9999-9999)">',
    };
}])

Try using phoneformat.js (http://www.phoneformat.com/), you can not only format phone number based on user locales (en-US, ja-JP, fr-FR, de-DE etc) but it also validates the phone number. Its very robust library based on googles libphonenumber project.

Answer 4

You will need to create custom form controls (as directives) for the phone number and the credit card. See section "Implementing custom form control (using ngModel)" on the forms page.

As Narretz already mentioned, Angular-ui's Mask directive should help get you started.

Answer 5

I solved this problem with a custom Angular filter as well, but mine takes advantage of regex capturing groups and so the code is really short. I pair it with a separate stripNonNumeric filter to sanitize the input:

app.filter('stripNonNumeric', function() {
    return function(input) {
        return (input == null) ? null : input.toString().replace(/\D/g, '');
    }
});

The phoneFormat filter properly formats a phone number with or without the area code. (I did not need international number support.)

app.filter('phoneFormat', function() {
    //this establishes 3 capture groups: the first has 3 digits, the second has 3 digits, the third has 4 digits. Strings which are not 7 or 10 digits numeric will fail.
    var phoneFormat = /^(\d{3})?(\d{3})(\d{4})$/;

    return function(input) {
        var parsed = phoneFormat.exec(input);

        //if input isn't either 7 or 10 characters numeric, just return input
        return (!parsed) ? input : ((parsed[1]) ? '(' + parsed[1] + ') ' : '') + parsed[2] + '-' + parsed[3];
    }
});

Use them simply:

<p>{{customer.phone | stripNonNumeric | phoneFormat}}</p>

The regex for the stripNonNumeric filter came from here.

Find Plunker for Formatting Credit Card Numbers using angularjs directive. Format Card Numbers in xxxxxxxxxxxx3456 Fromat.

angular.module('myApp', [])

   .directive('maskInput', function() {
    return {
