Question

I’ve found several jQuery syntaxes for nullifying the enter on a form.

First one:

$("form input[@type=text]").bind("keypress", function(e) {
  var code=e.charCode || e.keyCode;
  return (code==13)?false:true;
});

Second one:

$("form").bind("keypress", function(e) {
   if (e.keyCode == 13) return false;
});

My version:

$('form').keypress(function(e) {
   if (e.which == 13) return false;
});

My question is:

Q: Is my version ok to use, or is there a best practice for defeating the enter key from doing a form submit?

Answer 1

I think your method is probably fine. Capturing the form’s submit event won’t really help for your situation, because there’s no way (that I can think of at least) to know how the form was submitted.

The only suggestion I would make is to change return false; to e.preventDefault();
