自动刷新表不起作用

I want to refresh my table every 5 seconds..

Now I'm using this code:

<script type="text/javascript">
    $(document).ready(function(){
      refreshTable();
    });

    function refreshTable(){
        $('#content').load('refresh_data_dapur.php');
        setTimeout(refreshTable, 5000);
    }
</script>

refresh_data_dapur.php

$sql = "select t.no_meja, d.nama_menu,d.jumlah,t.status from detail_transaksi d join transaksi t on(d.id_transaksi=t.id_transaksi) where t.status ='pending' and d.status_menu = 'pending'";
$result = mysql_query($sql);
                    echo '<table cellpadding="5" cellspacing="0" border="1">';
                    echo '<tr>';
                    echo    '<th>No Meja</th>';
                    echo    '<th>Nama Menu</th>';
                    echo    '<th>Jumlah</th>';      
                    echo    '<th>Status</th>';      
                    echo '</tr>';
                    while($detail_transaksi = mysql_fetch_array($result))
                    {
                    echo    '<tr>';
                    echo    '<td>';
                    echo    $detail_transaksi['no_meja'];
                    echo'</td>';
                    echo    '<td>';
                    echo $detail_transaksi['nama_menu'];
                    echo '</td>';
                    echo    '<td>';
                    echo $detail_transaksi['jumlah'];
                    echo '</td>';
                    echo    '<td>';
                    echo $detail_transaksi['status'];
                    echo '</td>';
                    echo  '</tr>';
                    }

in my html :

<div id="content">

</div>

When I try to load the page, it doesn't show anything...

When in the html I modify into this code, it shows the data but the table still isn't refreshing...

<div id="content">
    <?php include("refresh_data_dapur.php");?>
 </div>

How can I fix this?

Everything is fine here. but you are using setTimeout(refreshTable, 5000);. It will run the refreshTable function once after 5 seconds of page load. You should be using

setInterval(refreshTable, 5000);

instead. That will run every five second and keep it outside and after refreshTable function because you are using it in setTimeout before it is declared. That might be the cause.
