AngularJSディレクティブを使用して入力フィールドに数値を自動的にフォーマットする方法を疑問に思いましたか？入力フィールドに入力すると6042919283私は604-291-9283として表示されています。
ありがとう

ui utils mask を使用できます。 Allowd Input Formatを定義でき、フォーマット
の検証を処理できます。他のヒント
あなたの電話番号が一律であるならば、私はすべての番号が桁10のものです10は働く
app.directive('formatPhone', [
function() {
return {
require: 'ngModel',
restrict: 'A',
link: function(scope, elem, attrs, ctrl, ngModel) {
elem.add(phonenumber).on('keyup', function() {
var origVal = elem.val().replace(/[^\w\s]/gi, '');
if(origVal.length === 10) {
var str = origVal.replace(/(.{3})/g,"$1-");
var phone = str.slice(0, -2) + str.slice(-1);
jQuery("#phonenumber").val(phone);
}
});
}
};
}
]);
とあなたのHTML;
<input type="text" id="phonenumber" ng-model="phonenumber" format-phone>
これは私がカスタム指令でそれをした方法です。
CustomDirective.js
demoApp.directive('phoneInput', [ '$filter', '$browser', function($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.$parsers.push(function(viewValue) {
return viewValue.replace(/[^0-9]/g, '').slice(0,10);
});
// This runs when the model gets updated on the scope directly and keeps our view in sync
ngModelCtrl.$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() {
$browser.defer(listener);
});
}
};
}]);
とこのカスタムフィルタの使用モデルをフィルタリングできます。
customfilter.js
demoApp.filter('tel', function () {
return function (tel) {
console.log(tel);
if (!tel) { return ''; }
var value = tel.toString().trim().replace(/^\+/, '');
if (value.match(/[^0-9]/)) {
return tel;
}
var country, city, number;
switch (value.length) {
case 1:
case 2:
case 3:
city = value;
break;
default:
city = value.slice(0, 3);
number = value.slice(3);
}
if(number){
if(number.length>3){
number = number.slice(0, 3) + '-' + number.slice(3,7);
}
else{
number = number;
}
return ("(" + city + ") " + number).trim();
}
else{
return "(" + city;
}
};
});
html
<input type = "text" id="phonenumber" phone-input ng-model="USPhone" >
<p>{{USPhone | tel}}</p>
これを書いて、かなりうまく機能します。唯一のキャッチは、ダッシュ " - "を番号に削除することはできません。このコードは、そのために考慮に簡単に変更できます。
さらに、私は、電話番号が無効な場合にカスタムメッセージを設定できることをユーザーが設定できることをユーザーが設定できるようにすることができます。
app.directive("phoneNumberValidator", function () {
return {
require: "ngModel",
restrict: "A",
link: function (scope, elem, attrs, ctrl) {
var domElement = elem[0]; // Get DOM element
var phoneNumberRegex = new RegExp("\\d{3}\\-\\d{3}\\-\\d{4}"); // Phone number regex
var cursorIndex; // Index where the cursor should be
// Create a parser to alter and validate if our
// value is a valid phone number
ctrl.$parsers.push(function (value) {
// If our value is non-existent, we return undefined
// WHY?: an angular model value should be undefined if it is empty
if (typeof value === "undefined" || value === null || value == "") {
ctrl.$setValidity('invalidFormat', true); // No invalid format if the value of the phone number is empty
return undefined;
}
// PARSER LOGIC
// =compare our value to a modified value after it has
// been transformed into a "nice" phone number. If these
// values are different, we set the viewValue to
// the "nice" phone number. If these values are the same,
// we render the viewValue (aka. "nice" phone number)
var prevValue, nextValue;
prevValue = value;
nextValue = value.replace(/[\D]/gi, ""); // Strip all non-digits
// Make the "nice" phone number
if (nextValue.length >= 4 && nextValue.length <= 6) {
nextValue = nextValue.replace(/(\d{3})(\d{3})?/, "$1-$2");
} else if (nextValue.length >= 7 && nextValue.length <= 10) {
nextValue = nextValue.replace(/(\d{3})(\d{3})(\d{4})?/, "$1-$2-$3");
}
// Save the correct index where the custor should be
// WHY?: we do this here because "ctrl.$render()" shifts
// the cursor index to the end of the phone number
cursorIndex = domElement.selectionStart;
if (prevValue != nextValue) {
ctrl.$setViewValue(nextValue); // *Calling this function will run all functions in ctrl.$parsers!
} else {
ctrl.$render(); // Render the new, "nice" phone number
}
// If our cursor lands on an index where a dash "-" is,
// move it up by one
if (cursorIndex == 4 || cursorIndex == 8) {
cursorIndex = cursorIndex + 1;
}
var valid = phoneNumberRegex.test(value); // Test the validity of our phone number
ctrl.$setValidity('invalidFormat', valid); // Set the validity of the phone number field
domElement.setSelectionRange(cursorIndex, cursorIndex); // Assign the cursor to the correct index
return value; // Return the updated value
});
}
}
});
バリデータを置くための最良の場所は、ここで見つかった証拠からの私の答えを見つけました。 http://radify.io/blog/underStanding-ngmodelController-By-example-part-/a>。これが私の答えが他の人とは少し違う理由です。
<input type="tel" class="form-control" id="PhoneNumber" name="PhoneNumber" ng-model="PhoneNumber" placeholder="Phone" maxlength="12" ng-value="PhoneNumber" required phone-number-validator server-validation>
<p class="help-block" ng-if="PhoneNumber.$error.invalidFormat">Phone Number is invalid</p>
Custom directive for telephone format using angularjs
The field change format as user typing
Restricts the input to numbers only
Auto formats the input (541) 754-3010
app.directive("phoneNumberValidator", function () {
return {
restrict: 'A',
link: function (scope, elem, attrs, ctrl, ngModel) {
elem.add(phonenumber).on('keyup', function () {
var input = elem.val();
// Strip all characters from the input except digits
input = input.replace(/\D/g, '');
// Trim the remaining input to ten characters, to preserve phone number format
input = input.substring(0, 10);
// Based upon the length of the string, we add formatting as necessary
var size = input.length;
if (size == 0) {
input = input;
} else if (size < 4) {
input = '(' + input;
} else if (size < 7) {
input = '(' + input.substring(0, 3) + ') ' + input.substring(3, 6);
} else {
input = '(' + input.substring(0, 3) + ') ' + input.substring(3, 6) + ' - ' + input.substring(6, 10);
}
jQuery("#phonenumber").val(input);
});
}
}

Wasn't a big fan of any of the answers here so came up with a directive of my own. It formats number with white space. Doesn't use jquery and you don't have to track key strokes.
.directive('reformatPhoneNumber', function() {
return {
require: 'ngModel',
link: function(scope, element, attrs, modelCtrl) {
modelCtrl.$parsers.push(function(number) {
var transformedNumber = number;
if (number.match(/^\d{4}$/)) {
transformedNumber = number.slice(0, 3) + " " + number.slice(3);
}
if(number.match(/^[\d\s]{8}$/)){
transformedNumber = number.slice(0, 7) + " " + number.slice(7);
}
if (number.length > 12) {
transformedNumber = number.slice(0, 12);
}
if (transformedNumber !== number) {
modelCtrl.$setViewValue(transformedNumber);
modelCtrl.$render();
}
return transformedNumber;
});
}
};
});
