                                $scope.role.responsibilities.push({name : ""});
                                $scope.role.responsibilities.push({name : ""});
                                $scope.role.responsibilities.push({name : ""});
                                currentDepartment = "";
                                console.log($scope.role.responsibilities.name);
                                $scope.role.responsibilities.splice(index, 1);


                            //$scope.save();
                        }

i want to remove empty value of object and how can do it? give me some suggestions..

Answer 1

do you mean remove a property of an object ?

like -

var a = {
    b : 1 
};

delete a.b; // a.b === undefined now 

Answer 2

You need to delete the property of the object using the following:

delete object.property

Here in this case, you can simply delete the properties as:

delete $scope.role.responsibilities.name;

Refer : https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete

Answer 3

You have to use angular custom filter for it.
