如何在ajax响应中获取数组到另一个字段

Question

我有一个类似的数组

[{"id_pelanggan":"1","id_tipe":"5","nama_pelanggan":"ASD","alamat_jalan":"DS","alamat_kota":"1","alamat_provinsi":"ATA","kontak_pelanggan":"45454"}]

还有我的 ajax

$(function() {
  $("#autocomplete").change(function(){
    var namaagen = $("#autocomplete").val();
    $.ajax({
      url: '<?php echo site_url('Pelanggan/tampil_where'); ?>',
      type: 'POST',
      dataType: 'json',
      data: {
        'namaagen': namaagen
      },
      success: function (agen) {
        $("#napem").val(agen['nama_pelanggan']);
      }
    });
  });
});
  });
});

控制器：

public function tampil_where(){  
$nama = $this->input->post('namaagen');
$query = $this->pelanggan_m->tampilwhere($nama);
echo json_encode($query);}

型号：

public function tampilwhere($nama){
$this->db->select('*');
$this->db->from('nm_pelanggan');
$this->db->where('nama_pelanggan',$nama);
$this->db->order_by('id_pelanggan', 'ASC');
$query = $this->db->get()->result_array();
return $query;
}

但什么也没发生，我已经添加 alert(agen['nama_pelanggan']); 以响应成功并显示警报未定义请帮助，谢谢提前

请更改您的警报代码，现在您没有以正确的方式访问响应数组：-

alert(agen[0]['nama_pelanggan']);

代替：-

alert(agen['nama_pelanggan']);

谢谢
