Reusing recurrent function in AngularJS

Question

I have a function that keeps repeating itself in my controller.
It looks like this:

//FUNCTION 1



$scope.selectedage = [];

$scope.pushage = function (age) {

    age.chosen = true;

    $scope.selectedage.push(age);

    console.log($scope.selectedage);

};

$scope.unpushage = function (age) {

    age.chosen = false;

    var index=$scope.selectedage.indexOf(age)

    $scope.selectedage.splice(index,1);     

    console.log($scope.selectedage);

}





//FUNCTION 2



$scope.selectedgender = [];

$scope.pushgender = function (gender) {

    gender.chosen = true;

    $scope.selectedgender.push(gender);

    console.log($scope.selectedgender);

}; 

$scope.unpushgender = function (gender) {

    gender.chosen = false;

    var index=$scope.selectedgender.indexOf(gender)

    $scope.selectedgender.splice(index,1);     

    console.log($scope.selectedgender);

}

I have it like 8 times for 8 different arrays.

Is there any way to write it once and reuse it just changing some values?

Answer 1

You can make a generic function that accepts a value (container) where it needs to write the "value". Like:

$scope.push = function(container, value){
    value.chosen = true;
    container.push(value);
    console.log(container);
}

$scope.unpush = function(container, value){
    value.chosen = false;
    var index = container.indexOf(value)
    container.splice(index, 1);     
    console.log(container);
}

//sample
$scope.push($scope.selectedage, 10);
$scope.push($scope.selectedgender, "Male");
