                            <th>Insert</th>
                          </tr>
                        </thead>
                        <tbody class="list">
                        </tbody>
                      </table>
            </div>
            <div class="modal-footer">
                
            </div>
        </div>
    </div>
</div>

this is the jquery code

var args = {
        autoBrightnessValue: 100,
        resultFunction: function(res) {
            [].forEach.call(scannerLaser, function(el) {
                $(el).fadeOut(300, function() {
                    $(el).fadeIn(300);
                });
            });
            scannedImg.attr("src", res.imgData);
            scannedQR.text(res.format + ": " + res.code);
            console.log(res.code);
            document.getElementsByName('qrcode')[0].value = res.code;
            var kode= res.code;
            $('#kode_barang').text(': '+kode);
            $.ajax({
                url:"{{ route('daftar_produk.scan') }}",
                method:'GET',
                data:{kode:kode},
                dataType:'json',
                success:function(data)
                  {
                    $('.list').html(data.table_data)
                  }
              });
            $('#myModal').modal('show');
        },

this is the controller

public function cekScan(Request $req)
    {
        $id = $req->get('kode');
        $output='';
        $produk = Produk::findOrFail($id)
        ->where('kode_barang', '=', $id)
        ->select('produks.*')
        ->first();

        $no = 0;
        $data = array();
        foreach ($produk as $list) {
            $no ++;
            $output .= '<tr><td>'.$no.'</td><td>'.$list->nama_barang.'</td><td>'."Rp.".format_uang($list->harga_jual).'</td><td>'.$list->stok.'</td><td><a type="button" data-stok=(('.$list->stok.')) data-id=(('.$list->id.')) data-nama=(('.$list->nama_barang.')) data-kode=(('.$list->kode_barang.')) data-harga=(('.$list->harga_jual.')) class="btn btn-primary btn-pilih" role="button">Insert</a></td></tr>';
        }
        $data = array(
            'table_data' =>  $output
        );
        return json_encode($data);
    }

this is the route

 Route::get('transaksi/scan', 'AppHttpControllersProdukController@cekScan')->name('daftar_produk.scan');

what should i do the error said “jquery.min.js:2 GET http://localhost:8080/rezkastore1/%7B%7B%20route(‘daftar_produk.scan’)%20%7D%7D?kode=2135758676 404 (Not Found)”

Answer

I have no idea wether you write your Javascript section, in Laravel Blade View or in separate JS file. If you write it within Laravel Blade Template, you may use

    $.ajax({
        url:"{{ route('daftar_produk.scan') }}",

but I recommend you to write complete URL within your AJAX call. Make your AJAX call like this :

$.ajax({
    url:"/transaksi/scan",
    method:'GET',
    data:{kode:kode},
    dataType:'json',
    success:function(data) {
        $('.list').html(data.table_data)
    }
});

Instead of using findOrFail(), you can use find() or regular where() with error handler, because findOrFail() will returns 404 not found if it can’t find any records, here is the cekScan function

public function cekScan(Request $req)
{
    $id = $req->get('kode');
    $output='';
    $produk = Produk::where('kode_barang', '=', $id)->first();

    if (!$produk) {
        return json_encode(['table_data' => 'Barang Tidak Ditemukan']);
    }

    $no = 0;
    $data = array();
    foreach ($produk as $list) {
        $no ++;
        $output .= '<tr><td>'.$no.'</td><td>'.$list->nama_barang.'</td><td>'."Rp.".format_uang($list->harga_jual).'</td><td>'.$list->stok.'</td><td><a type="button" data-stok=(('.$list->stok.')) data-id=(('.$list->id.')) data-nama=(('.$list->nama_barang.')) data-kode=(('.$list->kode_barang.')) data-harga=(('.$list->harga_jual.')) class="btn btn-primary btn-pilih" role="button">Insert</a></td></tr>';
    }
    $data = array(
        'table_data' =>  $output
    );
    return json_encode($data);
}
