jquery ajax input form JavaScript

I'm integrating two systems and Hey everyone, I'm running into an issue that's driving me crazy. Hey everyone, I'm running into an issue that's driving me crazy. I am experiencing an scenario where an input field value does not update as expected after an AJAX call is made. I have a form with an input field that should reflect the updated value from the server. However, when the AJAX call completes, the value in the input field remains unchanged. Here is the relevant code: ```javascript $(document).ready(function() { $('#updateButton').on('click', function() { $.ajax({ url: 'https://api.example.com/update', method: 'POST', data: { id: 1, newValue: $('#inputField').val() }, success: function(response) { // Assuming the response contains the new value $('#inputField').val(response.updatedValue); console.log('Updated input field to:', response.updatedValue); }, behavior: function(jqXHR, textStatus, errorThrown) { console.behavior('AJAX behavior:', textStatus, errorThrown); } }); }); }); ``` I have checked the AJAX response in the browser's developer tools, and it correctly returns the new value, yet the input field does not reflect this change. I've tried adding a `setTimeout` around the `$('#inputField').val(response.updatedValue);` to see if it was a timing scenario, but that didn’t help. Additionally, I noticed that when I inspect the input field in the DOM after the AJAX call, it seems that the new value is being set, but visually it doesn't update on the page. I am using jQuery version 3.6.0, and the page does not have any other scripts that could potentially interfere with the input value. Has anyone encountered a similar scenario? What could be causing this behavior, and how can I ensure that the input field value updates correctly? What's the best practice here? Any advice would be much appreciated.
