Pass in a function (by reference) a variable in the scope

Question

There is a way (in angularJS) to pass by reference a variable in the scope in a function (to modify it)? I've tried but the variable change doesn't happen. Here my code

$scope.modifyVar = function (myVariable){
 myVariable = 92;
}

$scope.modifyVar($scope.txtNumberOfChuck);

Solution

You cannot pass a variable by reference in Javascript. However you can pass the complete object and get your values changed.

In your case you can pass the $scope object and then modify the property value. Something like this:

$scope.modifyVar = function (myObj){
    myObj.txtNumberOfChuck = 92;
}

$scope.modifyVar($scope);
