Finding the maximum bottom value of scrollTop on a div?

In vanilla JS:

var maxScrollTop = el.scrollHeight - el.offsetHeight

Here's a version that accounts for padding and uses prop instead of accessing the DOM element directly.

$('#box').prop('scrollHeight') - $('#box').innerHeight();

here you go:

var trueDivHeight = $('.someclass')[0].scrollHeight;
var divHeight = $('.someclass').height();
var scrollLeft = trueDivHeight - divHeight;
alert(scrollLeft);
