Angular JS is failing to update views when passing dynamic IDs

I have implemented a method in my controller where I pass a dynamic id using the ng-init function, fetch a response through ajax calls, and try to print the response. However, I am facing an issue as the response is not getting printed. I am using ng-repeat to iterate over a list and calling ng-init for each element in the list. Despite this, the view does not get updated with the response.

Here is the HTML code snippet:

<div class="col-xs-12 chalg-list" ng-repeat="element in elements">
 <div class="col-sm-10 col-xs-9 pzero" ng-init="getActivity(element.id)">               
 <p><span>Activity Names</span> <span>{{names._element.id}}</span></p> 
 </div>
 </div>



And here is the corresponding Javascript code:

$scope.getActivity(_id){
//getting response through ajax calls    
            $scope.names._id = data; //every time a dynamic id will come but the view doesn't update
        console.log($scope.activities._id)     
  }

If anyone could kindly assist me, it would be greatly appreciated as I am running out of time.

Answer №1

Is Angular's $digest cycle not being triggered? How can you fetch AJAX content, either using the $http service or another method? Trying out $scope.$applyAsync() might be a solution.

Update: Keep in mind that if possible, it's best to let Angular handle this process for you. Angular's $http service, for instance, automatically initiates the $digest cycle for you.

Answer №2

It appears that the elements are already present in your controller. Is there a specific reason for calling the getActivity function from the view? It might be more efficient to handle all of this logic within the controller and simply use ng-repeat to display the data.

You could implement something similar to the following in your controller:

var arrElements = [1,2,3]; // include your id's here
$scope.elements =[]; 
arrElements.forEach(function(item){
   // retrieve data for each id using $http .... 
   // add it to the elements array
   $scope.elements.push( .... );
});

Then, in your view:

<div class="col-xs-12 chalg-list" ng-repeat="element in elements">
     <!-- display your data here -->
     {{element}}
</div>
