基于类别动态自动完成

Question

i have a problem when i am trying to create a autocomplete with dynamic value that based on combobox using codeigniter, i have tried using ajax and no success.

here is my ajax code for calling item in category

<script type="text/javascript">
$(document).ready(function() {  
    $("#jenis").change(function(){              
        $.ajax({
            type : "POST",
            url: "<?php echo base_url(); ?>whz/admin/get_item",
            dataType: "html",
            data : "item=" + $("#jenis").val(),
            success: function(data)
            { 
                $("#showitem").text(data);  
            }
        });
    });
});
</script>

this is my autocomplete jquery code

<div id="showitem">
    <script>
     $(function() {
        var availableTags = [
        <?php foreach ($item as $row){
                echo '"'.$row->item_name.'",';}?>
        ];
        $( "#autotags" ).autocomplete({
        source: availableTags
        });
     });
    </script>
</div>

and here is my controller

public function get_item()
    {
        $this->load->model('whz_model');
        $category = $this->input->post('item');
        $item=$this->whz_model->get_item_by_cat($category);
        $script = '
          $(function() {
            var availableTags = [';
            foreach ($item as $row)
            {
                $script .= '"'.$row->item_name.'",';
            }

        $script .= '];
            $( "#autotags" ).autocomplete({
              source: availableTags
            });
          });';

        echo $script;
    }

i am considering using json as another option, but i still don't have enough experience using it.

sorry for bad english, thanks for your help
