Question

how would you disable the usage of the enter key on a text area until a character is entered?

this is for a form i’m building – purely for aesthetic reasons 🙂

a bit like the facebook news feed page where you can’t press enter until entering a single character?

many thanks in advance!

Using jQuery:

$("textarea").live("keydown", function(e){
    if(e.which === 13 && $(this).val() === "")
        e.preventDefault();
});

Note that if your goal is to avoid any new line characters at the top of a textarea, this won’t prevent someone from pasting in new lines.
