$.each($('textarea[name=source]').val().split('\n'), function(e){
    alert(this);
 });

how can i convert it so it read the text in reverse order

Answer 1

Use .reverse() and loop.

var myArray = $('textarea[name=source]').val().split('\n');
myArray.reverse();

$.each(myArray, function(){
    alert(this);
});

Answer 2

you can use reverse() directly instead of using a temporary variable to hold your array data.

jsfiddle demo

$.each($('textarea[name=source]').val().split('\n').reverse(), function(e){
    alert(this);
 });
