javascript - Angularjs类确认按钮

我正在尝试为我网站的用户创建一个“确认”按钮，以查看他们何时单击按钮，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，都会收到错误消息

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

有谁知道为什么会这样，我该如何解决？

最佳答案

只需从this.$scope中删除​​this.$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
  }
}
