Angularjs Class Confirm button

Question

I am trying to create a "confirm" button for users of my website to see when they click on a button, and I am using an angularJS class. My code is as follows:

class TodosListCtrl {
  constructor($scope, $window){
    $scope.viewModel(this);
    this.$scope = $scope;
  }
//... a bunch of functions
  Clear(){
    var delete = this.$scope.confirm("Are you sure you want to clear the text?");
    if(delete){
      //delete stuff
  }
}

But every time I click on the button that calls the "Clear()" function, I get the error

"this.$scope.confirm is not a function at TodosListCtrl.Clear"

Does anyone know why this is happening, and how I can fix this?

Answer 1

Just take this.$scope off of this.$scope.confirm:

class TodosListCtrl {
  constructor($scope, $window){
    $scope.viewModel(this);
    this.$scope = $scope;
  }
//... a bunch of functions
  Clear(){
    var delete = confirm("Are you sure you want to clear the text?");
    if(delete){
      //delete stuff
  }
}
