Issue with JavaScript ScrollTop

Simply put, I am trying to determine the total scroll size for a text area in a unit that scrollTop can align with. However, I am at a loss on how to do so.

I've tried scrollHeight and various other methods without success. Any advice or suggestions would be greatly welcomed. Essentially, I need to adjust the scroll bar of a text area with variable dimensions and content length to be positioned precisely in the middle.

Just for clarification, I am working with Chrome 12.

Answer №1

Here's a useful tip for you:

To scroll to the middle of an element, use this code:
element.scrollTop = element.scrollHeight - (element.clientHeight / 2);

Answer №2

The following solution is effective for me:

$('#bar').scrollTop($('#bar')[0].scrollHeight / 2);
