输入框中的AngularJS货币格式

Question

Hi! I have the following input box :

<div ng-repeat="item in items"
    <input ng-model="item.cost" />
</div>

I am trying to figure out how to apply "currency" filter to the input box. So that when value is displayed it displays with $ sign and proper currency notations. I can do with span using {{item.cost | currency }} {{item.cost | currency }} but I need the box to be editable to change the value if needed. Please let me know how I can apply currency filter to the input box. Thanks

Try this

.directive('currencyFormatter', ['$filter', function ($filter) {


            formatter = function (num) {
              return $filter('currency')(num);
            };

        return {
          restrict: 'A',
          require: 'ngModel',
          link: function (scope, element, attr, ngModel) {
            ngModel.$parsers.push(function (str) {
             return str ? Number(str) : '';
            });
            ngModel.$formatters.push(formatter);

            element.bind('blur', function() {
              element.val(formatter(ngModel.$modelValue))
            });
            element.bind('focus', function () {
              element.val(ngModel.$modelValue);
            });
          }
        };
      }]);

And the html

<div ng-repeat="item in items">
    <input ng-model="item.cost" currency-formatter/>
  </div>
 <div ng-repeat="item in items">
    {{item.cost}}
  </div>
