jquery event-handling ajax javascript

Hey everyone, I'm running into an issue that's driving me crazy. I'm optimizing some code but I'm relatively new to this, so bear with me... I'm facing an issue where the `.hover()` event is not consistently triggering for elements that are dynamically added to the DOM. I'm using jQuery version 3.6.0 and trying to implement a tooltip feature for a list of items that are fetched via an AJAX call. The initial items respond to the hover event correctly, but when I add new items after the page loads, the hover event doesnโ€™t seem to work. Hereโ€™s the relevant code snippet: ```javascript $(document).ready(function() { // Function to fetch items function fetchItems() { $.ajax({ url: 'https://api.example.com/items', method: 'GET', success: function(data) { data.forEach(function(item) { $('#itemList').append(`<li class='item'>${item.name}</li>`); }); bindHoverEvents(); // Bind hover events after adding items }, error: function(xhr) { console.error('Error fetching items:', xhr); } }); } function bindHoverEvents() { $('.item').hover(function() { $(this).css('background-color', 'yellow'); }, function() { $(this).css('background-color', ''); }); } fetchItems(); }); ``` After running this code, the hover event works for the items loaded initially, but not for the ones added later. I tried calling `bindHoverEvents()` after each item is appended, but it seems ineffective. I even added a console log inside the hover function to see if itโ€™s being called, but it never prints for the new items. Is there a better way to handle events for dynamically added elements? Should I be using event delegation instead? If so, how can I implement that in this case? Any help would be appreciated! My development environment is Windows. What am I doing wrong? I'd really appreciate any guidance on this. I'm coming from a different tech stack and learning Javascript. I'm developing on Windows 11 with Javascript. Am I approaching this the right way?
