Javascript how to split newline

Question

I\'m using jquery, and I have a textarea. When I submit by my button I will alert each text separated by newline. How to split my text when there is a newline?

Answer 1

1. Move the var ks = $('#keywords').val().split("\n"); inside the event handler
2. Use alert(ks[k]) instead of alert(k)

  (function($){
     $(document).ready(function(){
        $('#data').submit(function(e){
           e.preventDefault();
           var ks = $('#keywords').val().split("\n");
           alert(ks[0]);
           $.each(ks, function(k){
              alert(ks[k]);
           });
        });
     });
  })(jQuery);
