Use .reverse() and loop.

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

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

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

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

reverse is not jquery.. it is just javascript. – Venkata Krishna Feb 11 '15 at 21:12
once you use `.val()` you are out of the jQuery chain. The `split()` returns a standard array, and `.reverse()` is a method of `Array.prototype`. – Patrick Gunderson Feb 11 '15 at 21:14
