javascript - Angularjs 类确认按钮

Question

我正在尝试为我的网站用户创建一个“确认”按钮，以便他们在单击按钮时看到，并且我正在使用 angularJS 类。我的代码如下:

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
  }
}

但是每次我单击调用“Clear()”函数的按钮时，都会收到错误

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

有谁知道为什么会发生这种情况，以及如何解决这个问题？

只需将 this.$scope 从 this.$scope.confirm 中删除即可:

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
  }
}
