jQuery not preserving changes in input fields after form submission with AJAX

jquery ajax forms JavaScript

I'm reviewing some code and I'm trying to debug I'm working with an scenario where my jQuery code is not preserving input field values after I submit a form using AJAX... My form submits successfully, but when I try to submit it again, the input fields reset to their default values instead of keeping the new ones. This is problematic because I want to allow users to edit their inputs without losing their changes. Hereโ€™s a simplified version of my code: ```html <form id="myForm"> <input type="text" name="username" value="JohnDoe" /> <input type="submit" value="Submit" /> </form> <div id="response"></div> ``` ```javascript $(document).ready(function() { $('#myForm').on('submit', function(event) { event.preventDefault(); $.ajax({ url: '/submit', type: 'POST', data: $(this).serialize(), success: function(data) { $('#response').html('<p>Form submitted successfully!</p>'); // Update input values on success $('input[name="username"]').val(data.username); }, behavior: function(jqXHR, textStatus, errorThrown) { console.behavior('Submission failed: ' + textStatus); } }); }); }); ``` The server responds with a JSON object that includes the username, but each time I submit the form, it resets. Iโ€™ve tried different ways to maintain the values, such as storing them in a variable and reassigning them, but itโ€™s still not working as expected. I looked for issues related to AJAX and jQuery, and Iโ€™m not finding a clear answer. Am I missing something crucial here? Any suggestions would be greatly appreciated! My team is using Javascript for this web app. Is there a simpler solution I'm overlooking? This is my first time working with Javascript latest. Any suggestions would be helpful.
