Pregunta uno (formato del número de teléfono):
Tengo que formatear un número de teléfono en AngularJS pero no hay ningún filtro para ello.¿Hay alguna manera de usar filtro o moneda para formatear 10 dígitos? (555) 555-5255?¿Y aún conservar el tipo de datos del campo como entero?
Pregunta dos (enmascarar el número de tarjeta de crédito):
Tengo un campo de tarjeta de crédito asignado a AngularJS, como:
<input type="text" ng-model="customer.creditCardNumber">
que devuelve el número entero (4111111111111111).Me gustaría enmascararlo con xxx los primeros 12 dígitos y mostrar solo los últimos 4.Estaba pensando en usar filtro:límite para esto, pero no tengo claro cómo.¿Algunas ideas?¿Hay alguna manera de formatear también el número con guiones pero aún así conservar el tipo de datos como entero?algo así como 4111-1111-1111-1111.
Solución
Además, si necesita formatear el número de teléfono solo en la salida, puede usar un filtro personalizado como este:
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();
};
});
Luego, puede usar este filtro en su plantilla:
{{ phoneNumber | tel }}
<span ng-bind="phoneNumber | tel"></span>
Otros consejos
He creado un módulo angularJS para manejar este problema con respecto a los fonenos para mí con una directiva personalizada y un filtro acompañante.
jsfiddle Ejemplo: http://jsfiddle.net/aberke/s0xpkgmq/
Filtro de uso Ejemplo:
<p>{{ phonenumberValue | phonenumber }}</p>
Código de filtro:
.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;
};
});
Ejemplo de uso de la directiva:
<phonenumber-directive placeholder="'Input phonenumber here'" model='myModel.phonenumber'></phonenumber-directive>
Código de directiva:
.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)">',
};
}])
código completo con módulo y cómo usarlo: https://gist.github.com/aberke/042eef0f37dba1138f9e
Como sugirió Shailbenq, telefeformat es increíble.
Incluye formato de teléfono en su sitio web.Cree un filtro para el módulo angular o su aplicación.
angular.module('ng')
.filter('tel', function () {
return function (phoneNumber) {
if (!phoneNumber)
return phoneNumber;
return formatLocal('US', phoneNumber);
}
});
Luego, puede usar el filtro en su HTML.
{{phone|tel}}
OR
<span ng-bind="phone|tel"></span>
Si desea utilizar el filtro en su controlador.
var number = '5553219876';
var newNumber = $filter('tel')(number);
También encontré ese complemento JQuery que es fácil de incluir en tu aplicación Angular (también con Bower :D) y que verifica todos los códigos de país posibles con sus respectivas máscaras:entrada-tel-intl
Luego puedes usar el validationScript opción para comprobar la validez del valor de entrada.
angular-ui tiene una directiva para la entrada de enmascaramiento.Tal vez esto sea lo que desea para enmascarar (desafortunadamente, la documentación no es tan grande):
No creo que esto lo ayudará a ofuscar el número de tarjeta de crédito, sin embargo.
También puede verificar de la máscara de entrada .
Esta es una directiva y se llama ui-mask y también es parte de angular-ui.utils biblioteca.
Aquí está funcionando: Ejemplo en vivo
Por el momento de escribir este post no hay ejemplos de usar esta directiva, por lo que he hecho un ejemplo muy simple
para demostrar cómo funciona esta cosa en la práctica.
Esta es la forma sencilla.Como básico, lo tomé de http://codepen.io/rpdasilva/pen/dpbff , yhecho algunos cambios.Porque el código ahora es más simplemente. Y puede obtener: en el controlador - " 4124561232 ", en la vista " (412) 456-1232 "
Filtro:
myApp.filter 'tel', ->
(tel) ->
if !tel
return ''
value = tel.toString().trim().replace(/^\+/, '')
city = undefined
number = undefined
res = null
switch value.length
when 1, 2, 3
city = value
else
city = value.slice(0, 3)
number = value.slice(3)
if number
if number.length > 3
number = number.slice(0, 3) + '-' + number.slice(3, 7)
else
number = number
res = ('(' + city + ') ' + number).trim()
else
res = '(' + city
return res
y directiva:
myApp.directive 'phoneInput', ($filter, $browser) ->
require: 'ngModel'
scope:
phone: '=ngModel'
link: ($scope, $element, $attrs) ->
$scope.$watch "phone", (newVal, oldVal) ->
value = newVal.toString().replace(/[^0-9]/g, '').slice 0, 10
$scope.phone = value
$element.val $filter('tel')(value, false)
return

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.
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,,,,
I took aberke's solution and modified it to suit my taste.
- It produces a single input element
- It optionally accepts extensions
- For US numbers it skips the leading country code
- Standard naming conventions
- Uses class from using code; doesn't make up a class
- Allows use of any other attributes allowed on an input element
My Code Pen
var myApp = angular.module('myApp', []);
myApp.controller('exampleController',
function exampleController($scope) {
$scope.user = { profile: {HomePhone: '(719) 465-0001 x1234'}};
$scope.homePhonePrompt = "Home Phone";
});
myApp

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.
Simple filter something like this (use numeric class on input end filter charchter in []):
<script type="text/javascript">
// Only allow number input
$('.numeric').keyup(function () {
this.value = this.value.replace(/[^0-9+-\.\,\;\:\s()]/g, ''); // this is filter for telefon number !!!
});
Here is the way I created ssn directive which checks for the the pattern and I have used RobinHerbots jquery.inputmask
angular.module('SocialSecurityNumberDirective', [])
.directive('socialSecurityNumber', socialSecurityNumber);
function socialSecurityNumber() {
var jquery = require('jquery');
var inputmask = require("jquery.inputmask");
return {
require: 'ngModel',
restrict: 'A',
priority: 1000,
link: function(scope,element, attr, ctrl) {
var jquery_element = jquery(element);
jquery_element.inputmask({mask:"***-**-****",autoUnmask:true});
jquery_element.on('keyup paste focus blur', function() {
var val = element.val();
ctrl.$setViewValue(val);
ctrl.$render();
});
var pattern = /^\d{9}$/;
var newValue = null;
ctrl.$validators.ssnDigits = function(value) {
newValue = element.val();
return newValue === '' ? true : pattern.test(newValue);
};
}
};
}
I solved this problem with a custom Angular filter as well, but mine takes advantage of regex capturing groups and so the code is really short. I pair it with a separate stripNonNumeric filter to sanitize the input:
app.filter('stripNonNumeric', function() {
return function(input) {
return (input == null) ? null : input.toString().replace(/\D/g, '');
}
});
The phoneFormat filter properly formats a phone number with or without the area code. (I did not need international number support.)
app.filter('phoneFormat', function() {
//this establishes 3 capture groups: the first has 3 digits, the second has 3 digits, the third has 4 digits. Strings which are not 7 or 10 digits numeric will fail.
var phoneFormat = /^(\d{3})?(\d{3})(\d{4})$/;
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.

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>
