ajax no funciton due e.preventdefault error and no update DB

Question

few days ago I change my PHP version from 5.4 to 5.5 due to some code needed for render QR code. And today i found error in this function:

$(function changeStav() {

            $("#selPismoSet<?php echo $id;?>").change(function() {
                var del_id = $(this).attr("id");
                del_id = del_id.replace("selPismoSet","");
                var id = del_id;
                var val = $('#selPismoSet<?php echo $id;?> option:selected').val();

                $.ajax({
                    type: "GET",
                    url: "actions.php?action=changeStav",
                    data: 'id=' + id+ '&stav=' + val,
                    success: function(data){
                        e.preventDefault();
                        $('#content, #ok<?php echo $id;?>').html(data);
                        console.log();
                    }
                });

                return false;           
            });

        });

I got this error:

I dont know where is the problem. Its possible that error is due to change PHP version?

So you have error "e is not defined" and still you couldn't figure out the problem? — dfsq, Feb 23 '18 at 08:59
`e` is usually an JavaScript event object and has nothing to do with PHP, don't know what event do you want to prevent there? :) — xander, Feb 23 '18 at 09:00

Isn't it a bit late running `preventDefault()` in the success method? — RiggsFolly, Feb 23 '18 at 09:19

You are missing an argument in your function. e is not defined

$(function changeStav() {

            $("#selPismoSet<?php echo $id;?>").change(function(e) {
                var del_id = $(this).attr("id");
                del_id = del_id.replace("selPismoSet","");
                var id = del_id;
                var val = $('#selPismoSet<?php echo $id;?> option:selected').val();

                $.ajax({
                    type: "GET",
                    url: "actions.php?action=changeStav",
                    data: 'id=' + id+ '&stav=' + val,
                    success: function(data){
                        e.preventDefault();
                        $('#content, #ok<?php echo $id;?>').html(data);
                        console.log();
                    }
                });

                return false;           
            });

        });

@RiggsFolly yes i think so too. actually i dont know the reason why did op added a `preventDefault()` in his function. – jerome Feb 23 '18 at 09:22
@jerome @RiggsFolly - i dont know why but without e.preventDefault() `$('#content, #ok').html(data);` cant load the div #content – Stanley01 Feb 23 '18 at 14:21
