I've been working on this all day and I've been struggling with this for a few days now and could really use some help. I'm having trouble with the `.slideToggle()` method in jQuery when used inside a table that is generated dynamically. I create the table rows and cells with JavaScript, and when I try to toggle a detail row beneath each main row, it doesn't toggle as expected. The detail rows are not being shown or hidden when the main row is clicked. Hereโ€™s a simplified version of my code: ```html <table id='myTable'> <thead> <tr> <th>Name</th> <th>Details</th> </tr> </thead> <tbody> <tr class='main-row'> <td>Item 1</td> <td><button class='toggle-details'>Toggle Details</button></td> </tr> <tr class='detail-row' style='display:none;'> <td colspan='2'>Details about Item 1</td> </tr> <tr class='main-row'> <td>Item 2</td> <td><button class='toggle-details'>Toggle Details</button></td> </tr> <tr class='detail-row' style='display:none;'> <td colspan='2'>Details about Item 2</td> </tr> </tbody> </table> ``` Iโ€™m using jQuery 3.6.0 and I have this script to handle the click event: ```javascript $(document).on('click', '.toggle-details', function() { $(this).closest('tr').next('.detail-row').slideToggle(); }); ``` When I click the toggle button, nothing happens. I initially thought it might be an scenario with event delegation since the rows are generated dynamically, but I'm using `$(document).on()` for event binding. I have also checked to ensure that the class names match correctly, which they do. The console doesn't show any errors, but the expected behavior isnโ€™t happening. I even tried replacing `.next()` with `.siblings()`, but that did not work either. Is there something Iโ€™m missing, or a better way to achieve this? Any hints would be greatly appreciated! For context: I'm using Javascript on Linux. I recently upgraded to Javascript 3.9. I appreciate any insights! I'm using Javascript 3.9 in this project.
