Don’t create ids with brackets "[" or "]" in them. They are special characters.

That would be id="item" and you never set up an autocomplete for it.

By the time your code reaches the success, counter may have changed. And, your code won’t work.

That’s just one of the problems with using "array-like" ids.

Consider changing to…

var newRow = $("<tr>").data("counter",counter);

Then whenever you need the right counter you can code

var counter = $(this).closest("tr").data("counter");

i change to

$(document).ready(function () {
    var counter = 1;

    $("#addrow").on("click", function () {
        var newRow = $("<tr>").data("counter",counter);
        var cols = "";
        cols += '<td><input type="text" style="width: 200px;" id="item' + counter + '" name="item[' + counter + ']" autocomplete="off" placeholder="Item"></td>';
        cols += '<td><input type="text" style="width: 100px;" id="harga' + counter + '" name="harga[' + counter + ']" placeholder="Harga"> </td>';
        cols += '<td><input type="text" style="width: 50px;" id="qty' + counter + '" name="qty[' + counter + ']" placeholder="Qty" onkeyup="findTotal(); findJumlah()"> </td>';
        cols += '<td><input type="text" style="width: 100px;" id="diskon' + counter + '" name="diskon[' + counter + ']" placeholder="Diskon"> </td>';
        cols += '<td><input type="text" id="total' + counter + '" name="total[' + counter + ']" placeholder="Total"></td>';
        cols += '<td><input type="button" style="width: 50px;" class="ibtnDel btn btn-md btn-danger" value="-" onclick="findJumlah()"></td>';
        newRow.append(cols);
        newRow.insertBefore("tr.isi");
        $("#item"+counter).autocomplete({
                source: function(request, response) {
                $.ajax({
                url: "<?php echo site_url('Produk/data'); ?>",
                data: { id_barang: $("#item"+counter).val()},
                dataType: "json",
                type: "POST",
                success: function(data){
                console.log(data);
                response(data);
                }
            });
        },
    });
    $("#item"+counter).change(function(){
    var nmbarang = $(this).closest("tr").data("counter");
    $.ajax({
    url: '<?php echo site_url('Produk/tampil_where'); ?>',
    type: 'POST',
    dataType: 'json',
    data: {
            'nmbarang': nmbarang
          },
    success: function (barang) {
    console.log(barang);
    $("#harga"+counter).val(barang[0]['harga_barang']);
    }
    });
    });
        counter++;
    });

    $("table.order-list").on("click", ".ibtnDel", function (event) {
        $(this).closest("tr").remove();
        counter -= 1;
    });

and check the console like this

And consider using the autocomplete change event instead of the regular one.

You can’t decrement counter. If the user creates several rows, then deletes the second row, you get a row with the same counter.

$("table.order-list").on("click", ".ibtnDel", function (event) {
$(this).closest("tr").remove();
// counter -= 1;
});

And don’t update older comments on your posts. Just add the new comment at the end.

I can’t debug over 200 lines of html mixed with php in my head. Sorry.

You had it working for the dynamic rows, now it works for the static row. Try to debug it.
