Ionic Framework Popover JQuery addClass

我正在尝试使用以下方法将类添加到弹出窗口中：

$('#popoverbutton').addClass('someclass');

我已经准备好在文档中尝试过它，并通过 onclick="myfunction（）;" ..

但它只是不会将类添加到模板中的按钮，该按钮将在打开弹出框时调用。

我想这是因为弹出框仍然没有打开，那么我可以在显示弹出框后执行此操作吗？

如何让它在加载弹出窗口后立即运行一些 jquery？

下面是控制器的代码：

$scope.usefulData = {};
  $ionicModal.fromTemplateUrl('templates/mypopover.html', {
    scope: $scope
  }).then(function(modal) {
    $scope.modalMypopover = modal;
  });
  $scope.closeMypopover = function() {
    $scope.modalMypopover.hide();
  };
  $scope.mypopover = function() {
    $scope.modalMypopover.show();
  };
  $scope.doMypopover = function() {
    console.log('Doing mypopover');
    $timeout(function() {
      $scope.closeMypopover();
    }, 1000);
  };

为什么不采用 Angular 绑定？我的意思是：modal.shown事件处理程序上设置一个变量，并使用ng-class根据该值应用特定的类。

请参阅下面的代码片段：

angular.module('ionicApp', ['ionic'])
.controller('AppCtrl', function($scope, $ionicModal, $timeout) {
  
  $scope.btnClass = 'button-positive';
  
  $ionicModal.fromTemplateUrl('templates/mypopover.html', {
    scope: $scope
  }).then(function(modal) {
    $scope.modalMypopover = modal;
  });
  
  $scope.$on('modal.shown', function() {
     $scope.btnClass = 'button-assertive myClass';
  });
  $scope.closeMypopover = function() {
    $scope.modalMypopover.hide();
    $scope.btnClass = 'button-positive';
  };
  $scope.mypopover = function() {
    $scope.modalMypopover.show();
  };
  $scope.doMypopover = function() {
    console.log('Doing mypopover');
    $timeout(function() {
      $scope.closeMypopover();
    }, 1000);
  };
});
.myClass {
  font-weight: bold;
  font-style: italic;
  color: blue !important;
}
