Angularjs类确认按钮

Question

我正在努力创建一个＆＃34;确认＆＃34;我的网站用户按钮，看他们点击按钮，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
  }
}

但每次我点击调用＆＃34; Clear（）＆＃34;功能，我收到错误

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

有谁知道为什么会这样，以及我如何解决这个问题？

Answer 1

从this.$scope开始this.$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
  }
}
