jquery html event-handling JavaScript

I'm working on a personal project and This might be a silly question, but I've been struggling with this for a few days now and could really use some help... I'm experiencing an issue where the value of an input field is not updating correctly after a `.change()` event is triggered in jQuery v3.6.0. I have a select dropdown that should update a hidden input field based on the selected value. However, the hidden input does not reflect the new value until I manually focus and blur the input again, which is not the intended behavior. Here's the relevant HTML: ```html <select id="mySelect"> <option value="1">Option 1</option> <option value="2">Option 2</option> <option value="3">Option 3</option> </select> <input type="hidden" id="myHiddenInput" value="" /> ``` And the jQuery code I'm using: ```javascript $(document).ready(function() { $('#mySelect').on('change', function() { var selectedValue = $(this).val(); $('#myHiddenInput').val(selectedValue); console.log('Hidden input value set to: ' + selectedValue); }); }); ``` When I select a different option from the dropdown, the console logs the correct value, but the hidden input field remains empty until I click on it. I've also tried using `.trigger('change')` after setting the value, but that didn’t make any difference. I've checked for any conflicting scripts or CSS that might be interfering, but nothing stands out. Is there a known issue with jQuery's event handling in this scenario, or am I missing something? Any suggestions for ensuring the hidden input updates immediately without additional user interaction would be greatly appreciated! My development environment is Windows. I'd really appreciate any guidance on this. Am I missing something obvious? The stack includes Javascript and several other technologies. I'm working in a Windows 11 environment.
