intercept carriage return in a textarea

Question

How do you catch a carriage-return in a textarea and do a form post instead of a newline in the textarea?

Answer 1

Capture the keystroke, verify if it is enter, and then look for the parent form element and submit it:

$('#textAreaId').keydown(function (e) {
  var keyCode = e.keyCode || e.which;

  if (keyCode == 13) {
    $(this).parents('form').submit();
    return false;
  }
});
