Question

What is the reason behind the lack of access for modal to an external controller?

Imagine having this code in your main HTML file:

<body ng-app="app" ng-controller="session as vmSession">
...
<!-- Modal content goes here -->
</body>

Inside the modal, you have a link:

<a ui-sref="siteManagement({ site: vmSession.user.site._id })" ng-click="$dismiss()">Example</a>

However, the link does not navigate to the correct page. Instead, it redirects to the root siteManagement page instead of the user-specific one. I've observed that the modal window is assigned an ng-isolate-scope class. Could this be causing the issue?

One way to specify which $scope object the modal controller's scope will be inherited from is by using the $modal.open() function:

$modal.open({
  templateUrl: 'modal.html',
  controller: 'modal',
  scope: $scope
});

If you omit the scope: parameter, it will default to $rootScope, which is the parent of the session controller's scope. This can lead to issues accessing the data you need.

If you prefer not to utilize the resolve option as recommended in one of the responses, there is an alternative method using the scope option within the open function. By utilizing the scope option, you have the ability to specify the scope that you want your modal to be based on. For instance, you can pass your controller's scope as the scope attribute and allow the modal to access all the variables that are accessible to your controller.

It is important to mention that the $modal will generate a child scope based on the provided scope (or $rootScope if none is specified) in order to avoid contaminating the original scope.

In your modal controller, you have the flexibility to pass any variable:

  $scope.launchModal = function () {
    var modalInstance = $modal.open({
      templateUrl: '/templates/modal/yourModal.html',
      controller: YourModalCtrl,
      resolve: {
        dataValues: function () {
          return {
            valueOne: 'abc',
            anotherValue: {x: 'X', y: 'Y'}
          };
        }
      }
    });

    modalInstance.result.then(function (result) {
        // handle success result
    }, function (result) {
       // handle cancel result
    });
  };


var CustomModalCtrl = function ($scope, $modalInstance, dataValues) {
   var valueOne = dataValues.valueOne;
   var anotherValue = dataValues.anotherValue;

   $scope.performAction = function () {
      console.log(valueOne);
   };

   $scope.saveChanges = function () {          
       $modalInstance.close($scope.ResultValue);
   };

   $scope.cancelModifications = function () {
      $modalInstance.dismiss($scope.ResultValue);
   };
};
