Problem in function delete CodeIgniter with AJAX

Question

I want to delete a register in a table instrumentos, I'm using codeignite with AJAX and I have this function in my controller

public function deleteInstrument(){
    $id = $this->input->get('id');
    $sql = $this->db->where('id',$id)->delete('instrumentos');
    $r['response'] = 2;
    $r['content'] = 'deleted';
    echo json_encode($r);
}

And I have in my JavaScript the next function to delete:

function confirmarEliminar(){
    $("body").on("click","#tablaInstrumentos button",function(event){
        idseleccion=$(this).attr("value");
        alertify.confirm('Eliminar Registro',
                 'Esta seguro de eliminar el registro?',
                  function(idseleccion){
                    $.ajax({
                        url: base_url+'admin_ajax/deleteInstrument',
                        type: 'GET',
                        data:{id:idseleccion},
                        beforeSend:function(){
                        },
                        success:function(r){
                           if(r==2 ){
                               alert(id)

                           }
                        },
                        error:function(xhr, status, msg){
                            console.log(xhr.responseText);
                        }
                    });
                   }

            , function(){ alertify.error(idseleccion)});

    });}

I have this error in the console output

Uncaught TypeError: Illegal invocation

without seeing your mark-up I can only guess: `idseleccion=$(this).attr("value");` should be `idseleccion=$(this).val();` see here: https://stackoverflow.com/questions/8312820/jquery-val-vs-attrvalue AND the variable base_url? is it defined? I can't see how? — Vickel, Feb 17 '19 at 19:44

Please try this code in js: function confirmarEliminar(id) {

            $.post(base_url + "admin_ajax/deleteInstrument", {id: id}, function (data) {
                if (data.code == '1') {
                    bootbox.alert(data.message, function () {
                        $("#your row id" + id).remove();


                    });
                } else {
                    bootbox.alert('Something went wrong');
                }
                $(window).unblock();
            });

}

Controller Code:

public function deleteInstrument($id){ }
