AngularJS Class Confirmation Button

I'm currently working on implementing a "confirm" button for users of my website to see after clicking a specific button, using an angularJS class. Below is the code snippet I have written:

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

However, every time I click on the button triggering the "Clear()" function, I encounter the error 

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

Could someone please explain why this issue is occurring and provide guidance on how to resolve it?

Answer №1

Simply remove this.$scope from this.$scope.confirm:

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