我的控制器代码

app.controller('RoleViewCtrlq',['$scope','$modalInstance','$modal',function ($scope,$modalInstance,$modal) {


    $scope.open = function () {
        debugger;
        var modalInstance = $modal.open({
            templateUrl: 'myModalContent.html',});


        $scope.ok = function () {
            $modalInstance.close();
        };

        $scope.cancel = function () {
            $modalInstance.dismiss('cancel');
        };


    }
}
]);

在这里,我创建了样本
