Sticky Navbar脚本失效求助：滚动时导航栏无法固定

Hey there! Glad you’ve already narrowed down the problem to a specific script segment—this will make debugging much easier. To help pinpoint the exact fault, could you share:

• The specific JavaScript snippet you suspect is causing the issue
• A quick note on how your CSS is set up for the navbar (e.g., are you using position: sticky natively, or toggling a custom class with fixed positioning?)

In the meantime, here are some common script-related pitfalls that often break sticky navbar behavior:

• Incorrect scroll position checks: For example, using window.scrollY without comparing it to the navbar’s actual offset top (navbar.offsetTop)
• Failing to toggle the sticky class properly: Maybe your condition for adding/removing the class is reversed, or you’re targeting the wrong element
• Missing or misattached scroll event listeners: Double-check that you’re listening to the scroll event on the window object, not a parent container that doesn’t scroll
• Not accounting for dynamic content: If your navbar’s height or position changes after page load, your initial offset calculation might be outdated

Once you share the relevant code snippets, we can dive right into fixing the issue!
