I was wondering if this is possible to be done with jquery. Please see following code.

HTML

<table id="order">
    <tr>
        <td class="order_items"></td>
        <td class="order_items"></td>
        <td class="order_items"></td>
        <td class="order_items"></td>
        <td class="order_items"></td>
        <td class="order_items"></td>
    </tr>
    <tr>
        <td class="order_items"></td>
        <td class="order_items"></td>
        <td class="order_items"></td>
        <td class="order_items"></td>
        <td class="order_items"></td>
        <td class="order_items"></td>
    </tr>
    <tr>
        <td class="order_items"></td>
        <td class="order_items"></td>
        <td class="order_items"></td>
        <td class="order_items"></td>
        <td class="order_items"></td>
        <td class="order_items"></td>
    </tr>
</table>

javascript

$(document).ready(function(){
    $("td.load_ads").each(function(){
        $(this).html("Place a New Ad Free!");
    });
    var count=$("td.load_ads").length;  //18
    $.post('/fetch_orders.php',{count:count},function(data){
        var data_arr=data.split('/end');
        for(index=0;index < data_arr.length;index++){  //for each of the array values got back from fetch orders.php
            .
            ..
            ... Stuck here. How to make each data_arr(ie: each data_arr[index]) go into each td?

.POST script

$count =$_POST['count'];
$query="SELECT * FROM orders1_manager_orders ORDER BY RAND() LIMIT $count";
$db->setQuery($query);
$ads=$db->loadRowList();

foreach($ads as $ads_to_display){
    echo $orders_to_display[9].'/';
    echo $orders_to_display[10].'/end';
}

As explained in the title, i need each order to go into each empty td slot in the above html table. But if i were to put a .each function after my .post All of my tds will turn into the first data gotten from the script, meaning data_arr[1].
