Refactoring legacy jQuery code to improve event handling in a complex UI

jquery event-handling refactoring JavaScript

I've hit a wall trying to I recently switched to I'm trying to configure I'm stuck on something that should probably be simple. I've looked through the documentation and I'm still confused about While refactoring some legacy jQuery code, I need to address a recurring issue with event handling in a complex user interface. The application has numerous dynamically generated elements, and I suspect that the original developer used direct event binding, which is causing inconsistent behavior. For instance, in the original code, I see this pattern: ```javascript $('.some-button').on('click', function() { // Some action }); ``` This seems problematic because elements are created dynamically, and this event binding does not apply to those added later. I've tried switching to event delegation like so: ```javascript $(document).on('click', '.some-button', function() { // Some action }); ``` However, even with this change, I'm noticing that some buttons still do not trigger the expected behavior. I also checked for any issues with event propagation, but nothing stands out. The application is built with jQuery 3.5.1, and I’m not certain if there are any conflicts or deprecated features from earlier jQuery versions affecting the new approach. I’m considering implementing a more modular approach using the `$.each()` function to attach events to elements after they are created. Does anyone have insights on the best practices for handling events in dynamically generated content with jQuery? Should I also look into potential performance impacts of binding to the document level compared to directly binding to specific parent elements? Any advice or recommendations on tools for debugging this would also be appreciated. I'd really appreciate any guidance on this. Cheers for any assistance! I've been using Javascript for about a year now. Has anyone else encountered this? I'm working on a web app that needs to handle this. Could this be a known issue?
