jquery css-selectors dom-manipulation JavaScript

I'm maintaining legacy code that I need help solving I've been banging my head against this for hours..... I'm currently working with an scenario where jQuery's `.each()` method isn't iterating over elements as expected within a complex DOM structure. I have a nested list where each `li` has a corresponding `div` that I want to access. For some reason, the callback function receives the wrong elements in the iteration. Here's a simplified version of my HTML: ```html <ul class="parent"> <li class="item"> Item 1 <div class="details">Details 1</div> </li> <li class="item"> Item 2 <div class="details">Details 2</div> </li> </ul> ``` And here’s the jQuery code I'm using: ```javascript $('.item').each(function(index) { console.log($(this).find('.details').text()); // I expect to see 'Details 1' and 'Details 2' }); ``` However, instead of printing the correct details, I get `undefined` for both iterations. I have verified that the `.details` class exists within each `li`, but it always seems to return `undefined`. I've also tried wrapping the `each()` call in a document ready function: ```javascript $(document).ready(function() { $('.item').each(function(index) { console.log($(this).find('.details').text()); }); }); ``` This still doesn't resolve the scenario. I suspect it might be due to some CSS or visibility styles affecting the `div` elements, but I need to pinpoint the question. The jQuery version I'm using is 3.6.0. Any insights on how I can resolve this scenario or debugging tips would be greatly appreciated. I'm working on a web app that needs to handle this. I'd really appreciate any guidance on this. This is part of a larger service I'm building. Is there a better approach? I'm coming from a different tech stack and learning Javascript.
