質問

質問1（電話番号の書式）：

私はAngularjsで電話番号をフォーマットしなければなりませんが、フィルタはありません。フィルタまたは通貨を使用して(555) 555-5255に10桁をフォーマットする方法はありますか？それでもフィールドのデータ型を整数として保持しますか？

質問2（マスキングクレジットカード番号）：

AngularJSにマッピングされているクレジットカードフィールドは、次のようになります。

<input type="text" ng-model="customer.creditCardNumber">
.

これは整数（4111111111111111）を返します。私は最初の12桁のxxxで隠したいと思います、そして最後の12桁のみを表示します。私はフィルタの使用を考えていました。何か案は？ダッシュを持つ数値をフォーマットする方法はありますが、それでもデータ型を整数として保持しますか？4111-1111-1111-1111。

解決

また、出力のみの電話番号のみをフォーマットする必要がある場合は、このようなカスタムフィルタを使用できます。

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();
    };
});

テンプレートでこのフィルタを使用できます。

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

他のヒント

私は、カスタム指令と付随するフィルタを持つ自己のための音声家に関してこの問題を処理するためのAngularJSモジュールを作成しました。

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

フィルタの使用例： <p>{{ phonenumberValue | phonenumber }}</p>

フィルタコード：

.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;
    };
});

ディレクティブ使用例：

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

ディレクティブコード：

.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)">',
    };
}])

モジュール付きのフルコードとその使い方： https://gist.github.com/aberke/042eef0f37dba1138f9e

Shailbenqが提案された場合、 PhoneFormat は素晴らしいです。

あなたのウェブサイトに電話フォーマットを含めます。角モジュールまたはアプリケーション用のフィルタを作成します。

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

        return formatLocal('US', phoneNumber); 
    }
});

その後、HTMLのフィルタを使用できます。

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

コントローラ内のフィルタを使用したい場合。

var number = '5553219876';
var newNumber = $filter('tel')(number);

Enter Image説明

私はまたあなたの角度アプリに含めやすいjQueryプラグイン（Bower：D）を含み、それぞれのマスクを使ってすべての可能な国コードをチェックすることもわかりました。 intl-tel-input

入力の値の有効性を確認するために、validationScriptオプションを使用できます。

angular-uiには、入力入力の指令があります。多分これはあなたがマスキングのために欲しいものです（残念ながら、ドキュメンテーションはそれほど大きな）：

http://angular-ui.github.com/

私はこれがクレジットカード番号を難読化するのに役立つとは思わない。

入力マスクフォーマッタを確認することもできます。

これはディレクティブで、ui-maskと呼ばれ、 angular-ui.utilsの一部です。/ a>ライブラリー。

機能： live例

この記事を書く時点では、この指令を使用する例はありませんので、このことを実際にどのように機能するかを実証するために非常に簡単な例を作りました。

これは簡単な方法です。基本的に私はそれを http://codepen.io/rpdasilva/pen/dpbff 、およびいくつかの変更を完了しました。今のコードはもっと簡単です。そしてあなたは得ることができます：コントローラ - " 4124561232 "、（412）456-1232 "

フィルター：

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
.

と指令：

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 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";

                city = value;
                break;

            default:
                country = value.slice(0, 2);

        }
        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();
        }

    };
});

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>
