Add new line character to textarea instead of submitting form

Question

I have a form with a text area and hitting the enter key submits my form. How can I make it to add a new line character instead of a form submit.

Answer 1

$(document).ready(function() {
  $('textarea').keydown(function(event){
    if (event.keyCode == 13) {
      event.preventDefault();
      var s = $(this).val();
      $(this).val(s+"\n");
    }
  });
});
