AngularJS Question

Angular, input field with a currency mask directive for money format on the fly

I'm trying to create an input mask for a EU money field using http://jquerypriceformat.com/

So far in my directive, the input shows correctly to the user with the mask applied, but I believe there's something wrong, because the POST values are being sent with weird formatting, totally different than what we see in the input field.

I include the priceformat.js

<script src="js/jquery.price_format.1.8.min.js"></script>

<input type="text" currency-input ng-model...>


And on angular:

app.directive('currencyInput', function() {
return {
require: '?ngModel',
link: function($scope, element, attrs, controller) {
element.priceFormat({
prefix: '',
centsSeparator: ',',
thousandsSeparator: '.'
});
}
};
});


My input shows the value with the mask correctly, but on POST data (called by angular) it's a different value, what am I missing?

input > 2.200,80 | post > 22,0080

Thanks

From your example I don't see that link returns something.

I would write directive something like:

.directive('format', ['$filter', function ($filter) {
    return {
        require: '?ngModel',
        link: function (scope, elem, attrs, ctrl) {
            if (!ctrl) return;


            ctrl.$formatters.unshift(function (a) {
                return $filter(attrs.format)(ctrl.$modelValue)
            });


            ctrl.$parsers.unshift(function (viewValue) {

          elem.priceFormat({
            prefix: '',
            centsSeparator: ',',
            thousandsSeparator: '.'
        });                

                return elem[0].value;
            });
        }
    };
}]);

If you want on start fire the filter, use $formatters:

Now link is:

link: function (scope, elem, attrs, ctrl) {
            if (!ctrl) return;

            var format = {
                    prefix: '',
                    centsSeparator: ',',
                    thousandsSeparator: ''
                };

            ctrl.$parsers.unshift(function (value) {
                elem.priceFormat(format);

                return elem[0].value;
            });

            ctrl.$formatters.unshift(function (value) {
                elem[0].value = ctrl.$modelValue * 100 ;
                elem.priceFormat(format);
                return elem[0].value;
            })
        }
