格式化input输入内容（金额）

项目中要用到格式化金额输入框，要求每三个数字用逗号分割开。

添加一个directive

angular.module('myApp.directives', [])
.directive('filterInput',['$filter', function ($filter){
            return {
                restrict: 'A',
                require: 'ngModel',
                link: function(scope, element, attr, ngModel) {

                    ngModel.$parsers.push(function fromUser(text) {
                        return parseInt(text.replace(",",""));
                    });

                    ngModel.$formatters.push(function toUser(text) {
                        console.log($filter('number')(text));
                        return ($filter('number')(text || ''));
                    });

                }
            };
        }]);
