I have a 2 textareas right beside each other and wanted to know how can I make it so when i scroll one the other one scrolls?
This needs to work no matter if both textareas are the same size or not. It is for comparing code.

Figured it out
everything you scroll textarea file_content it will take cnum to the same place
$(document).ready(function(){
$('#file_content').scroll(function(){
$('#cnum').animate({scrollTop: $('#file_content').scrollTop()});
});
});
