Closing SweetAlert After an AJAX Request: A Simple Guide

Problem: You're using SweetAlert to display a loading indicator while an AJAX request is in progress, but you want to automatically close the alert after the request completes (successfully or unsuccessfully).

Solution: This can be achieved by leveraging the complete callback function within your AJAX call, which is triggered regardless of success or failure.

Scenario:

Imagine you have a button that, when clicked, sends an AJAX request to update a user's profile. You want to display a loading indicator with SweetAlert while the request is being processed and then close it when the request is finished.

Original Code:

$('#update-profile-button').click(function() {
  Swal.fire({
    title: 'Updating Profile...',
    text: 'Please wait...',
    showConfirmButton: false,
    allowOutsideClick: false,
    onBeforeOpen: () => {
      Swal.showLoading();
    }
  });

  $.ajax({
    url: '/profile/update',
    type: 'POST',
    data: $('#profile-form').serialize(),
    success: function(response) {
      // Handle success response
    },
    error: function(error) {
      // Handle error response
    }
  });
});

Explanation:

The above code shows a basic setup with a button triggering an AJAX call to update the profile. It uses SweetAlert to display a loading indicator while the request is being processed. However, it lacks the functionality to close the SweetAlert upon request completion.

Solution with complete Callback:

$('#update-profile-button').click(function() {
  Swal.fire({
    title: 'Updating Profile...',
    text: 'Please wait...',
    showConfirmButton: false,
    allowOutsideClick: false,
    onBeforeOpen: () => {
      Swal.showLoading();
    }
  });

  $.ajax({
    url: '/profile/update',
    type: 'POST',
    data: $('#profile-form').serialize(),
    success: function(response) {
      // Handle success response
    },
    error: function(error) {
      // Handle error response
    },
    complete: function() {
      // Close SweetAlert on request completion
      Swal.close();
    }
  });
});

Analysis:

  1. complete callback: The complete callback in the AJAX call executes after both success and error callbacks, ensuring the SweetAlert is closed regardless of the request outcome.
  2. Swal.close(): This function gracefully closes the SweetAlert instance, removing the loading indicator from the screen.

Additional Considerations:

  • Error handling: You might want to display different SweetAlert messages based on success or error scenarios. For instance, you could show a success message upon successful profile update, or a failure message if an error occurs.
  • User experience: Consider providing a more informative message within the SweetAlert, like "Updating your profile..." or "Processing your request...". This makes the user experience more engaging and provides context about what is happening.

Conclusion:

By using the complete callback in your AJAX request, you can automatically close the SweetAlert upon request completion. This ensures a seamless user experience, eliminating the need for manual intervention to dismiss the loading indicator. Always remember to customize your SweetAlert messages to provide clear and informative feedback to your users.
