The concept of "lines" is not that highly implemented in JavaScript
in general. If you have free text, you would need font information
and a lot more for finding out how many lines your text will use. So,
there is no general way to determine the number of lines your text
has.
However, if your users use manual line breaks, it is possible. You
then evaluate the field value of such a field and count the new line
characters (\r), which then gives you the number of lines...
Hope, this can help.
