在AngularJS中格式化电话和信用卡号码

时间:2012-10-02 23:59:40

标签: angularjs number-formatting

问题一(格式化电话号码):

我不得不格式化AngularJS中的电话号码,但没有过滤器。有没有办法使用过滤器或货币格式化10位到(555) 555-5255?并仍然将字段的数据类型保留为整数?

问题二(屏蔽信用卡号):

我有一个映射到AngularJS的信用卡字段,例如:

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

返回整数(4111111111111111)。我想用xxx掩盖它的前12位数字,只显示最后的4位。我正在考虑使用filter:limit for this但是我不清楚如何。有任何想法吗?有没有办法用破折号格式化数字但仍保留数据类型为整数?有点4111-1111-1111-1111

此外,如果您只需要在输出上格式化电话号码,您可以使用这样的自定义过滤器:

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();
    };
});

然后您可以在模板中使用此过滤器:

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

我创建了一个AngularJS模块,通过自定义指令和附带的过滤器来处理有关我自己的语音问题。

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

过滤器使用示例:     <p>{{ phonenumberValue | phonenumber }}</p>

过滤代码:

.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;
    };
});

指令使用示例:

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

指令代码:

.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)">',
    };
}])

答案 2 :(得分:13)

正如shailbenq所说,phoneformat非常棒。

在您的网站中包含电话格式。为角度模块或应用程序创建过滤器。

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

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

然后您可以在HTML中使用过滤器。

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

如果要在控制器中使用过滤器。

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

我还发现JQuery插件很容易包含在你的Angular App(也有bower:D)中,并使用各自的掩码检查所有可能的国家代码: intl-tel-input

然后,您可以使用validationScript选项来检查输入值的有效性。

答案 4 :(得分:5)

Angular-ui有一个屏蔽输入的指令。也许这就是你想要掩盖的东西(不幸的是,文档并不那么棒):

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

但是,我认为这不会有助于模糊信用卡号码。

答案 5 :(得分:5)

您还可以检查输入掩码格式化程序

这是一个指令,它被称为ui-mask,它也是angular-ui.utils库的一部分。

此处有效: Live example

  

在写这篇文章的时候,没有任何使用这个指令的例子,所以我做了一个非常简单的例子来演示这个东西在实践中如何运作。

答案 6 :(得分:5)

这是一种简单的方法。基本上我从http://codepen.io/rpdasilva/pen/DpbFf获取了它,并做了一些改变。现在代码更简单。 你可以得到:在控制器中 - “ 4124561232 ”,在视图中“(412)456-1232

过滤器:

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

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

答案 7 :(得分:2)

尝试使用phoneformat.js(http://www.phoneformat.com/),您不仅可以根据用户区域设置(en-US,ja-JP,fr-FR,de-DE等)格式化电话号码,还可以验证电话号码。它非常强大的库基于googles libphonenumber项目。

我采用了艾博克的解决方案,并根据自己的喜好对其进行了修改。

  • 它生成一个输入元素
  • 可选择接受扩展程序
  • 对于美国号码,它会跳过主要国家/地区代码
  • 标准命名约定
  • 使用类来使用代码;没有组成一个班级
  • 允许使用输入元素上允许的任何其他属性

我也使用自定义角度过滤器解决了这个问题,但是我利用了正则表达式捕获组,因此代码非常简短。我将它与单独的stripNonNumeric过滤器配对以清理输入:

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

phoneFormat过滤器正确格式化带有或不带区号的电话号码。 (我不需要国际号码支持。)

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];
    }
});

简单地使用它们:

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