Try This. It's working-
HTML Form-

               

               Select Menu
                   
                    -- Select Menu --
                    
                      menu_name?>
                    
                    
                
               

               Select Sub Menu
                   
                       --Select Sub Menu--
                    
               
              

                  Image Title
                  
                
               

                        

                            Upload Photo:
                            
                            

                        
               
               Submit
           
  

Ajax -

$('#submit').submit(function(e){
    e.preventDefault(); 
         $.ajax({
             url:'Your path',
             type:"post",
             data:new FormData(this),
             processData:false,
             contentType:false,
             cache:false,
             async:false,
              success: function(data){
                  alert(data);
           }
         });
    });  

Just set url in ajax, It would work perfectly.
Controller function-

public function do_upload(){
        $config['upload_path']="./upload";
        $config['allowed_types']='gif|jpg|png';
        $this->load->library('upload',$config);
        if($this->upload->do_upload("file")){
        $data = array('upload_data' => $this->upload->data());
        $data1 = array(
        'menu_id' => $this->input->post('selectmenuid'),
        'submenu_id' => $this->input->post('selectsubmenu'),
        'imagetitle' => $this->input->post('imagetitle'),
        'imgpath' => $data['upload_data']['file_name']
        );  
        $result= $this->Admin_model->save_imagepath($data1);
        if ($result == TRUE) {
            echo "true";
        }
        }

     }
