I need to get the id Bairro3, I’m doing like this 

$(document).on('change', '#bairro', function(){
        var bairroID = $(this).val();

but it still doesn’t work.

You have to add a variable in the #neighborhood, for each form that opens has a different id #bairro1 #bairro2 #bairro3..., how can I do this, I imagine I would have to do this for the id #rua also #rua1 #rua2 #rua3...

$(document).ready(function(){

    $(document).on('change', '#sectionChooser', function(){
        var myID = $(this).val();
        $('.panel').each(function(){
            myID === $(this).attr('id') ? $(this).show() : $(this).hide();
            console.log("ok");
        });
    })


    $(document).on('change', '#bairro', function(){
        var bairroID = $(this).val();

        if(bairroID){
            $.ajax({
                type:'POST',
                url:'ajax_data2.php',
                data:'bairro_id='+bairroID,
                success:function(html){
                    $('#rua').html(html);
                    console.log("ok");
                }
            }); 
        }else{
            $('#rua').html('<option value="">Select categoria first</option>');

        }
    });

});

Html

    As I said in the chat, You do not need to create several ids... just create Names with arrays, type name="neighborhood[]"... and you can get the value of each one with $(document).on('change', '[name^="bairro"]', function(){ var bairroID = $(this).val();

  • Not looking too deeply into your question, growing id’s almost never (if ever) is what you want, but rather classes (all with the same), or a solution like @dvd indicated.

  • I think you could have focused on the other question which is almost the same thing as this, then you would have solved it all

  • It is obvious that if you use the selector by ID as here $(document).on('change', '#bairro' the result will always be "neighborhood". Why not make a selector by name, or tag type ( select, input, etc) or per class?

That’s the code, it worked

$(document).ready(function(){

    $(document).on('change', '#sectionChooser', function(){
        var myID = $(this).val();
        $('.panel').each(function(){
            myID === $(this).attr('id') ? $(this).show() : $(this).hide();
            console.log("ok");
        });
    })


   $(document).on('change', '[name^="bairro"]', function(){ var bairroID = $(this).val();
        console.log("ok");

        if(bairroID){
            $.ajax({
                type:'POST',
                url:'ajax_data2.php',
                data:'bairro_id='+bairroID,
                success:function(html){
                    $('#rua[name^="rua"]').html(html);

                }
            }); 
        }else{
            $('#rua').html('<option value="">Select categoria first</option>');

        }
    });

});
