javascript - How do I call a function within ajax using codeigniter to update -

i want call model function within ajax update data should in database.

my main function controller:

function m_addr(){     $this->load->view('m_add_view'); } 

this other function in controller 1 want call m_add_view edit data in database ajax while remaining in m_add_view.

what thinking should execute function m_update without leaving m_add_view view not have reload page.

function m_update($id, $text, $column_name){     $data = array('text'=>$text);     $this->db->where('id', $id);     $this->db->update($column_name, $data); } 

this code have far update is:

function edit_data(id, text, column_name){     $.ajax({         url:"<?php echo base_url(); ?>control/m_update",         method:"post",         data:{             id:id,             text:text,             column_name:column_name         },         datatype:"text",         success:function(data){             /*alert(data);*/             $('#infomsg').show();         }     }); } 

i want know how send id, text , colum_name m_update function update database behind scenes.

figured out how update it.

function m_update(){     $id = $this->input->post('id');     $text = $this->input->post('text');     $column_name = $this->input->post('column_name');     $data = array($column_name => $text);     $this->db->where('id', $id);     $this->db->update('table_name', $data); }
