拖放值更改

Question

在Codeigniter中，我尝试从包表中更改packageValue的值。首先，我根据packageValue从包表中获取列表包。 packageValue，例如1,2,3等。如果packageValue具有1，则必须在顶部查看。之后，2,3等。当我使用drap＆drop时，我想更改这些值。我想显示这个packageValue的值。我怎样才能做到这一点？

拖放视图：

<!-- Default items sorting -->
                <div class="card card-body border-top-info">
                    <div class="text-center">
                        <h6 class="font-weight-semibold mb-0">Drag & Drop</h6>
                        <p class="mb-3 text-muted">Drag the package you want to level up on other packages. This will take the package you are dragging from the other packages to the next level.</p>
                    </div>

                    <div class="dropdown-menu dropdown-menu-sortable" style="display: block; position: static; width: 100%; margin-top: 0; float: none;">
                        <?php foreach($all_packs as $get) { ?>
                        <li class="dropdown-item"><?php  echo $get->packageNameEn; ?> <?php echo '#'. ' ' ?><span><?php echo $get->packageValue; ?></span></li>
                        <?php } ?>
                    </div>
                </div>
                <!-- /default items sorting -->

Javascript：

<script>
    $(function () {
        $(".dropdown-menu-sortable").sortable({
            onDrop: function ($item, container, _super, event) {
                $('.dropdown-menu-sortable li').removeClass('dragged');
                $("body").removeClass('dragging');
                $('.dropdown-item span').each(function (i) {
                    var humanNum = i + 1;
                    $(this).html(humanNum + '');
                });
            }
        });
    });



</script>
