How to get the number of lines in a textarea?

by

The problem with using “\n” or “\r” is it only counts the number of returns, if you have a line that is long it could wrap and then it wouldn’t be counted as a new line. This is an alternative way to get the number of lines – so it may not be the best way.

Edit (thanks alex):

Script

$(document).ready(function(){
 var lht = parseInt($('textarea').css('lineHeight'),10);
 var lines = $('textarea').attr('scrollHeight') / lht;
 console.log(lines);
})
