Problem with Request via GET

I'm successfully using the script below to open in the Visual DIV the products for the selected brand:

Trademark Link:

<a class="marca" style="cursor:pointer;" id="'.$res['codigo'].'">'.$res['nome_marca'].'</a>

Script for Marks:

<script language="javascript">
////// Visualiza o produto da Marca selecionada //////
$(document).ready(function(){
    $('.marca').click(function(){
        var cod = $(this).attr('id');
        $.ajax({url:"prod_index_marca.php?codmarca="+cod,success:function(data){
            $('#visual').html(data);
            }
        });
    });
});
</script>

In the sequence, I would like to open the details of each selected Brand product within the Visual DIV for itself.

I used the same method to open the Tags, so:

Link to Product Details:

<a class="detalhe_5" style="cursor:pointer;" id="<?php echo $res['codigo']; ?>">
    <img style="width:100%; max-width:100px;" src="img_produtos/<?php echo $res['img01']; ?>" />
</a>

Script for Details:

<script language="javascript">
////// Para visualizar o item selecionado //////
$(document).ready(function(){
    $(".detalhe_5").click(function(){
        var cod = $(this).attr("id");
        $.ajax({
            url:"prod_detalhe_5.php?codigo="+cod,success:function(data){
            $("#visual").html(data);
            }
        });
    });
});
</script>

But I'm not getting an answer, when I click on the link, the page stays static, or nothing happens.

Can I rely on friends to solve this problem?

I can not figure out why it does not work.
