"Enhancing User Interaction with AngularJS: Leveraging ng-click and ng

Currently, I have a map with markers that trigger an overlay-div to open when clicked.

 <div class="map" ng-init="loadall()">
            <a ng-click="details.show=!details.show" href="#/dealer/{{marker.id}}" class="marker" style="left:{{marker.coordleft}}px;top:{{marker.coordtop}}px" ng-repeat="marker in dealer"></a>    
        </div>

This is the div that opens:

<div ng-show="details.show">      
    <div ng-view></div>
</div>

Issue at Hand:
My customer has noticed that when one marker's div is already open (details.show == true) and another marker is clicked, the div closes before reopening.

Desired Outcome:
I would like for the new content to load into the ng-view without closing and reopening the div if it is already open.

Can this functionality be achieved?

EDIT:

Details of My Routes:

app.config(['$routeProvider', function($routeProvider) {
  $routeProvider.
      when('/dealer/:id', {templateUrl: 'files/tpl/dealer-details.html?20', controller: 'DealerDetailsCtrl', activetab: 'details'}).
      when('/dealermessage/:id', {templateUrl: 'files/tpl/dealer-message.html?124', controller: 'DealerMessageCtrl', activetab: 'message'}).
      when('/dealersendmessage/:id', {templateUrl: 'files/tpl/dealer-details.html?8', controller: 'DealerDetailsCtrl', activetab: 'details'}).
      otherwise({redirectTo: '/dealer'});
}]);

When a marker is clicked, the respective route and controller are loaded. Could this information help resolve the issue?

Second Edit:
The toggle between "marker/div" now works, but there is a strange behavior with the opened overlay.

For Example:
Opening "Marker 1" displays the div correctly. However, when the div for "Marker 1" is open and I click on "Marker 2," the div refreshes with the content of "Marker 2." But then, clicking back on "Marker 1" suddenly closes the div.
How can this unexpected behavior be prevented?

Answer №1

Although it may seem confusing at first, the concept here is to use a single model to control multiple markers. By doing this, clicking on one marker will open it while simultaneously closing another marker, as the state of each marker is not stored individually. To achieve this functionality, consider implementing the following code:

<div ng-repeat="marker in locations">
   <a ng-click="details.show=toggle(marker)" href="#/location/{{marker.id}}" 
      class="marker" style="left:{{marker.coordleft}}px;top:{{marker.coordtop}}px"></a>
</div>

In your controller, define the toggle function as follows:

$scope.toggle = function(marker) {
   marker.show = !marker.show;

   return marker.show;
};

It is important to add more logic to your ng-click handler, as demonstrated in @asgoth's answer.

Alternatively, you can consider another solution that involves passing $event into your ng-click handler:

<a ng-click="handleOverlay($event)" ... ></a>

Afterwards, store the srcElement on $scope (

$scope.openMarker = ev.srcElement

). This way, handleOverlay() can determine whether the click is occurring on the already open element or on a new one for each click event.

Without knowledge of how you are reloading ng-view, it may be necessary to review additional code. For example, are different controllers being loaded for each new view? If so, storing the srcElement on a service or rootScope could be beneficial to ensure its availability during view/controller changes.

After studying asgoth's approach and addressing Marek123's feedback, I have come up with an improved version of the code:

$scope.selectedMarker = {};
$scope.toggle = function(marker) {
  //assuming each dealer has a unique "id"
  if (marker.id !== $scope.selectedMarker.id) {
      _.each($scope.delear, function(value, index) {
        $scope.delear[index].show = false;
      });
    }
   marker.show = !marker.show;
   return marker.show;
};
