表格不发布数据

Question

JSfiddle: http://jsfiddle.net/NqaZ2/4/

I have two forms on a page, One posts fine but the other does not post anything:

<form id="comment-oa" action="" method="post">
    <input type="hidden" name="key" value="coa" />
    <input type="hidden" name="action" value="" />
    <input type="hidden" name="value" value="" />
</form>

Its being submitted through jquery:

$('a[data-role="fc-delete"]').click(function(){
    var id = $(this).parent().parent().parent().parent().attr('id'),
        spl = id.split("-");

    $('#comment-oa input[name="action"]').attr('value', "delete");
    $('#comment-oa input[name="value"]').attr('value', spl[0]);
    $('#comment-oa').submit();

});

and I'm simply just doing print_r($_POST) at the moment, but it just comes up with Array ( ).

I've checked whether jQuery puts values in and it does (firefox inspector pic):

EDIT:

The other form:

<form action="" method="post">
    <textarea name="comment"></textarea>
    <input type="hidden" name="reply-id" value="" />
    <input type="submit" value="Post comment" />
    <input type="button" value="cancel" style="display: none;" />
</form>

Update:

$('a[data-role="fc-delete"]').click(function(){
    var id = $(this).parent().parent().parent().parent().attr('id'),
        spl = id.split("-");

    $('#comment-oa input[name="action"]').attr('value', "delete");
    $('#comment-oa input[name="value"]').attr('value', spl[0]);
    $('#comment-oa').submit();

});

to

$('a[data-role="fc-delete"]').click(function(e){
e.preventDefault();
    var id = $(this).parent().parent().parent().parent().attr('id'),
        spl = id.split("-");

    $('#comment-oa input[name="action"]').attr('value', "delete");
    $('#comment-oa input[name="value"]').attr('value', spl[0]);
    $('#comment-oa').submit();

});

Your using a link without preventing it form well - linking.
