jQuery not triggering .focus() event on dynamically created input fields within a modal

jquery bootstrap modal focus JavaScript

I'm getting frustrated with I'm trying to figure out I'm sure I'm missing something obvious here, but I'm having trouble with triggering the `.focus()` event on input fields that are created dynamically within a Bootstrap modal. The modal is generated after the user clicks a button, and once the modal is shown, I attempt to set focus on an input field inside it. However, the `.focus()` event doesn’t seem to work as expected. Here’s the relevant part of my code: ```javascript $('#myButton').on('click', function() { $('#myModal').modal('show'); setTimeout(function() { $('#myModal input[name="myInput"]').focus(); }, 100); }); ``` The modal is properly displayed, and I can see the input field. However, it doesn’t receive focus when I expect it to. I also tried wrapping the `.focus()` call within a `.on('shown.bs.modal', function() { ... })` handler, but that did not yield any results either. Here’s that attempt: ```javascript $('#myModal').on('shown.bs.modal', function () { $('#myModal input[name="myInput"]').focus(); }); ``` Despite these attempts, the input field remains unfocused. I verified that the input field is not disabled and that there are no console errors. Additionally, I checked that the jQuery and Bootstrap versions I’m using are compatible (jQuery 3.6.0 and Bootstrap 5.1.0). I even tried adding a slight delay before calling `.focus()`, but it still doesn’t work. What could be the reason for this behavior? Are there any known issues with dynamically added content and focus events in jQuery or Bootstrap? Any help or suggestions would be appreciated! How would you solve this?
