cara kondisi jquery codeigniter view (implement condition jquery codeigniter view)

-------------------------------------------------------------------------------------------------------------
data yang akan dikirim oleh post ajax :
<script>
function searchFilter(page_num, sortBy1) {
    page_num = page_num?page_num:0;
    var keywords = $('#keywords').val();
    var rowPage = $('#rowPage').val();
    var typeKomoditas = $('#typeKomoditas').val();
    var sortBy = $('#sortBy').val();
    var data_value = '';
 
    if(sortBy1 === undefined){
    data_value = 'page='+page_num+'&keywords='+keywords+'&rowPage='+rowPage+'&typeKomoditas='+typeKomoditas+'&sortBy='+sortBy;
    }
    else{
    data_value = 'page='+page_num+'&keywords='+keywords+'&rowPage='+rowPage+'&typeKomoditas='+typeKomoditas+'&sortBy='+sortBy+'&sortBy1='+sortBy1;
    }

    $.ajax({
        type: 'POST',
        url: '<?php echo base_url(); ?>produk/produk_pagination/produk_terlaris/'+page_num,
        data: data_value,
        beforeSend: function () {
            $('.loading').show();
        },
        success: function (html) {
            $('#postList').html(html);
            $('.loading').fadeOut("slow");
        }
    });
    if (sortBy==1) {
    condition = 'atas benar';
    }else{
    condition = 'bawah salah';
}


    console.log(condition);
}
</script>
-----------------------------------------------------------------------------------------------------------------------
kita ambil data di atas oleh controller sesuai arahan nya :
-> kita ambil satu array untuk kondisi

$data['get_tipe_produk_terlaris'] = $data['posts'][0];
----------------------------------------------------------------------------------------------------------------------
<?php
  if($get_tipe_produk_terlaris['tipe_produk_terlaris']==1):
?>
<th style="text-align: center">
Masukan Benar
</th>
<?php
else :
?>
<th style="text-align: center">
Masukan Salah
</th>
<?php
endif;
?>
