当我们从数据库中获取json数组时，此代码在codeigniter中不起作用。我们如何使用ajax

从数据库中获取数据

select to_char(hire_date,'month'),count(employee_id)
from employees
group by to_char(hire_date,'month')


TO_CHAR(HIRE_DATE,'MONTH')           COUNT(EMPLOYEE_ID)
------------------------------------ ------------------
march                                                17

november                                              5

Answer 1

这就是你所需要的

1.Controller：

var csv = "118.0000000000,102.6666666666,110.6666666666,97.5000000000,82.5000000000,86.6666666666";
var csv35 = substr(csv, 0, 35);
var nums = csv35.split(",");
nums.length--;

2。型号：

class Ajax extends CI_Controller
{
    public function Users($id)
    {
        $this->load->model('User_mdel');
        echo json_encode($this->User_mdel->list());
    }
}

3。查看

class User_mdel extends CI_Model
{
    public function list()
    {
        return $this->db->get('users')->result();
    }
}

和END

使用CodeIgniter中的AJAX从数据库中获取数据
