สอบถามครับ ใช้ javascript ใน GoogleChrome แล้วไม่ส่งค่าครับแต่ใน IE,Firefox ไม่มีปัญหา

switch(true){
	case $_POST['submitt'] == "no":
		$id = $_POST['idsubmitt'];
		$update_no = "update tb_news set status_n = 'Y' where id_n = '$id'";
		mysql_select_db($database, $connection);
		$query_no = mysql_query($update_no, $connection);
		if($query_no)
		{
			echo "<script>window.location = 'admin_news.php';</script>";
		}
		break;
}
	

function dosubmit(type)
	{
		document.form2.submitt.value = type;
		document.form2.submit();
	}
function idsubmit(type)
	{
		document.form2.idsubmitt.value = type;
		document.form2.submit();
	}


<a href = "#" onclick="javascript:dosubmit('no');javascript:idsubmit('<?php echo $fetch['id_n']; ?>')"><img src="images/icon/red.png" width="20" height="20" border="0"  /></a>
