php – Submit textarea form without a submit button with Enter key press

Background:

I\’m making a facebook wall-alike page, which will have many posts and you should be able to comment every post. So in this one page there are many forms (of course). And I only need to submit one of them.

So yes, I have found answers to this question , but none of them work, so asking here:

I got a form like this:

    <form enctype=\"text/plain\" action=\"submitcomment.php\" method=\"post\" target=\"output_frame\" id=\"comment<?php echo $prepare_data[\'post_id\']; ?>\">
    <textarea name=\"comment\" id=\"comment\" onkeypress=\"return submitViaEnter(event)\" value=\"\" autocomplete=\"off\"></textarea>
    <input type=\"hidden\" name=\"hiddenid\" id=\"hiddenid\" value=\"<?php echo $prepare_data[\'post_id\']; ?>\" />
    </form>

and my JavaScript function looks like this:

function submitViaEnter(evt) {
    evt = (evt) ? evt : event;
    var target = (evt.target) ? evt.target : evt.srcElement;
    var form = target.form;
    var charCode = (evt.charCode) ? evt.charCode : ((evt.which) ? evt.which : evt.keyCode);
    if (charCode == 13) {
        document.forms[this.form.id].submit();
        alert(\"sent!\");
        return false;
    }
    return true;
}

If I use a textbox, it works, but when I use textarea, it is not working. Trying to press enter does nothing.
