Question

这是代码

App.js

(...)

  .state('app.dishdetails', {
    url: '/menu/:id',
    views: {
      'mainContent': {
        templateUrl: 'templates/dishdetail.html',
        controller: 'DishDetailController'
      }
    }
  });

Controller.js

    .controller('DishDetailController', ['$scope', '$stateParams', 'menuFactory', 'favoriteFactory', 'baseURL','$ionicPopover', '$ionicListDelegate', '$ionicModal', function($scope, $stateParams, menuFactory, favoriteFactory, baseURL, $ionicPopover, $ionicListDelegate, $ionicModal) {

                $scope.addFavoriteMenu = function(index){
                    console.log("index is " + index);
                };

            // .fromTemplateUrl() method
            $ionicPopover.fromTemplateUrl('templates/dish-detail-popover.html', {
              scope: $scope
           }).then(function(popover) {
              $scope.popover = popover;
           });

           $scope.openPopover = function($event) {
              $scope.popover.show($event);
           };

           $scope.closePopover = function() {
              $scope.popover.hide();
           };

           //Cleanup the popover when we're done with it!
           $scope.$on('$destroy', function() {
              $scope.popover.remove();
           });

           // Execute action on hide popover
           $scope.$on('popover.hidden', function() {
              // Execute action
           });

           // Execute action on remove popover
           $scope.$on('popover.removed', function() {
              // Execute action
           });
            }])

主要HTML

    <ion-view view-title="Dish Details">
    <ion-nav-buttons side="secondary">
      <div class="buttons">
        <button class="button button-icon icon ion-more"
          ng-click="openPopover($event)"></button>
      </div>
    </ion-nav-buttons>
  <ion-content>
      (...)
  </ion-content>
</ion-view>

弹出广告HTML

<ion-popover-view>
<ion-content>
    <ul class="list">
        <li class="item" ng-click="addFavoriteMenu({{dish.id}})">
            Add to Favorites
        </li>
    </ul>
</ion-content>

db.json

"dishes": [
    {"id": 0};
    {"id": 1};
    {"id": 2};
]

我无法在controller.js中的“addFavoriteMenu（{{dish.id}}）”中获取参数，它总是以未定义的形式出现

但是，当我尝试使用Google Chrome进行检查时，ID可以在[ion-popover-view]中正确显示

我在这里创造了什么错误？还是什么？

尝试重现您的问题我注意到您的JSON错误：每行末尾都有分号（;）而不是冒号（，）。

Howevere这是一个工作片段：

angular.module('ionicApp', ['ionic'])

.controller('AppCtrl', function($scope, $ionicPopover) {

  $scope.dishes = [
    {"id": 0},
    {"id": 1},
    {"id": 2}
  ];
  
  $scope.addFavoriteMenu = function(index) {
    console.log(index);
    alert("index is "+index);
  }
  
  $ionicPopover.fromTemplateUrl('templates/popover.html', {
    scope: $scope,
  }).then(function(popover) {
    $scope.popover = popover;
  });

});

Ionic Popover无法将参数传递给控制器
