Way back in the day, I use to always set up my event triggering anchor tags a certain way to prevent their default behaviour of having to click-through to a URL or named anchor:
Usually, a more simple approach was to use a simple hash:
<a href="#" class="trigger">Trigger</a>
That’s the way I should’ve been doing it, but I really hated how it always made the browser window jump to the top.
Solving that wasn’t too complicated. It just took a bit of jQuery.
With that code in place, the browser no longer jumps to the top when using a hashed anchor tag.
