var textarea_height = $(this).scrollHeight();
Wht does this zero index mean? It has been confusing me for a long tym?
And what is the difference between innerHeight And ScrollHeight In Jquery! Thx in advance…
It appears that the  is only used when trying to return scrollHeight. I have no idea what scrollHeight is, as I’ve never used it.

innerHeight is the height of an element, including its padding but not including its border.
thx, I am still confused y it’s used with scrollheight… :/
