Ionic Framework Popover JQuery addClass

Question

我正在尝试将 class 添加到弹出窗口：

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

我已经在文档中试过了准备好并通过onclick="myfunction();"发送..

但它不会将 class 添加到模板中将在打开弹出窗口时调用的按钮。

我在想这是因为弹出窗口还没有打开所以我可以在显示弹出窗口后执行此操作吗？

如何在加载弹出窗口后立即将其发送到运行一些 jquery？

控制器代码如下：

$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：在 modal.shown 事件处理程序上设置一个变量，并使用 ng-class 应用基于该值的特定 class。

请参阅下面的代码段：

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;
}
