Question

我正在使用ng-pattern来验证号码（逗号分隔输入字段仅允许号码）。但它在控制台中抛出以下错误，尽管它工作正常。谁能告诉我我做错了什么。

错误：SyntaxError：无效的正则表达式：/ ^ \ d + $ + \，/：无需重复在新的RegExp（）

＆＃13;

barapp.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.$parsers.unshift(function (viewValue) {
                var plainNumber = viewValue.replace(/[^\d|\-+|\.+]/g, '');
                elem.val($filter(attrs.format)(plainNumber));
                return plainNumber;
            });
        }
    };
}]);

<input type="text" name="money" class="form-control text-center" placeholder="Money" ng-model="money" ng-pattern="/^\d+$+\,/" required format="number">

你必须在模块中声明barapp。在行

之前尝试这个

var app = angular.module('barapp',[]);

barapp.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.$parsers.unshift(function (viewValue) {
                var plainNumber = viewValue.replace(/[^\d|\-+|\.+]/g, '');
                elem.val($filter(attrs.format)(plainNumber));
                return plainNumber;
            });
        }
    };
}]);

ng-pattern regex throw error
