Prevent the query from being executed by halting the AJAX call

Within my web application, I have a specific button that triggers an AJAX call upon being clicked. On the server side, I need to run a query against a database.

I am concerned about the execution time of these queries and worry that users may be impatient and wish to stop the process mid-way. Is there a way for me to incorporate an additional button that can halt the current AJAX call and query execution? And would this be a secure method to implement?

The technologies I am working with include AngularJS on the frontend and C# on the backend.

Implementing on the client side is simple

Tips for canceling/aborting jQuery AJAX requests

However, handling it on the server side is more complex compared to the client side. Check out this related post for further guidance

Answer №2

If you need to "cancel" a request on the client side, utilizing the $q service in AngularJS is an effective approach. By creating a deferred object and attaching it to your request using the "timeout" property in the $http({}) function call, you can easily handle cancellations.

function sendRequestToServer() {
  var canceler = $q.defer();

  var request = $http({
    method: "get",
    url: "/your/url",
    timeout: canceler.promise
  });

  var promise = request.then(function(response) {
    return response.data;
  });

  promise._canceler = canceler;

  return promise;
}


function cancel(requestPromise) {
  if (requestPromise && requestPromise._canceler && requestPromise._canceler.resolve) {  
    requestPromise._canceler.resolve();
  }
}

These functions are typically organized within the same angular service. Special thanks to Ben Nadel and his blog for the great tutorial and code!
