How can I use JavaScript and AJAX to validate an edit form?

To validate a form for editing clients, modals can be used instead of directly editing a record from the table. The current issue is that validation works only for the first record. When editing a different record, validation no longer works. The form code for the modals is given below. JavaScript code can be added to validate the form entries for each record. Please note the link provided for a better understanding of how it works.

It seems like you are trying to validate form entries for each record in modals. You can add individual validation checks for each input element by using methods of the Validation helper. To check for required fields, use Validation.RequireField (field, [error message]) (for an individual field) or Validation.RequireFields (field1, field2,...)) (for a list of fields). You can also restrict data input by using validation rules. I hope this helps. Let me know if you have any other questions.

The issue might be that the JavaScript code is only targeting the #rfcEdit input element and not the specific modal being opened. When a different modal is opened, the script is still referencing the previous modal's #rfcEdit element and not the current one being edited. One solution could be to add a unique class to the #rfcEdit element in each modal, and modify the JavaScript code to target that specific class instead of just the ID. This way, the script will only be working with the correct #rfcEdit element for the current modal being edited. Here's an example of how you can modify the code: 1. In the input element, add a unique class that corresponds to the modal ID:
<input class="form-control form__input rfc-edit-modal{{ $c->id }}" type="text" name="rfcEdit" id="rfcEdit" value="{{ $c->RFC }}" maxlength="14" minlength="10">
2. In the JavaScript code, adjust the selector to target the current modal's .rfc-edit-modal instead of just #rfcEdit:
$('.rfc-edit-modal').on('keyup', function() {

  // Get the current modal's ID
  var modalId = $(this).closest('.modal').attr('id');

  // Use the modal ID to find the specific input element to validate
  var rfc = $('#' + modalId + ' .rfc-edit-modal').val();

  // Rest of the code remains the same...
By doing this, the JavaScript code should now properly target only the #rfcEdit element within the currently opened modal and perform the validation as expected.
