jQuery not triggering custom events after AJAX call - need insights on event delegation

jquery ajax events JavaScript

Quick question that's been bugging me - I've searched everywhere and can't find a clear answer. I'm trying to figure out I've looked through the documentation and I'm still confused about I've been banging my head against this for hours..... During development of a code review tool, I've integrated jQuery to manage user interactions and notifications. My goal is to trigger custom events upon the successful completion of AJAX calls. However, events aren’t firing as expected after data is loaded dynamically. I've structured my code like this: ```javascript $.ajax({ url: 'https://api.example.com/data', method: 'GET', success: function(response) { $('#content').html(response); $('#content').trigger('dataLoaded'); // Custom event }, error: function() { console.error('Failed to load data.'); } }); ``` The custom event `dataLoaded` should notify other components that they can react accordingly. To ensure that the event is bound correctly, I've tried adding the event listener both before and after the AJAX call: ```javascript $(document).on('dataLoaded', function() { console.log('Data has been loaded successfully!'); }); ``` Despite this, the event listener doesn’t seem to catch the `dataLoaded` event when the content is inserted into the DOM. I’ve also verified that my jQuery version is 3.6.0, which should support event delegation. Because the content is loaded dynamically, I must consider whether the binding approach is appropriate. I’ve looked into `$(document).on('dataLoaded', ...)` as a way to capture the event. However, switching to this didn’t change the outcome. Additionally, I’ve read that using native JavaScript event handling might be an alternative. However, I prefer sticking to jQuery for consistency across the codebase. Is there a recommended approach to ensure custom events are captured correctly in a scenario like this? Any suggestions or insights into what I might be overlooking? This implementation is critical to my research, and any help would be greatly appreciated. This is part of a larger web app I'm building. I'd really appreciate any guidance on this. This is happening in both development and production on macOS. Thanks, I really appreciate it! Thanks in advance! Any advice would be much appreciated.
