动态 jquery ui 可排序块的索引/位置

不幸的是，我无法在jsfiddle中使用它，但也许我忽略了一些东西（http://jsfiddle.net/bJpyU/46/）。我动态创建了块，需要保存它们的下单。由于设置的动态方式，我无法获取索引（它始终为 0，并且无论拖动到何处，首先开始的块始终显示为第一个索引）。toArray 和序列化显示为空白。我什至尝试过数第n个孩子。知道如何获得订单吗？

简讯

var sortdiv = "Graphs"
var blockClasses = "col-lg-4";
    $(".sortable_portlet_" + sortdiv[2] + "_column").sortable({
        connectWith: ".sortable_portlet_" + sortdiv[2] + "_column",
        handle: ".portlet-title",
        //placeholder: "dragColumn",
        forceHelperSize: true,
        forcePlaceholderSize: true,
        start: function (e, ui) {
            ui.placeholder.height(ui.helper.outerHeight());
            ui.placeholder.width(ui.helper.outerWidth());
            // get original block size
            blockClasses = ui.item.parent().attr('class');
        },
        stop: function (e, ui) {
            var parent = ui.item.parent();
            blockWidth = blockClasses.split(" ");
            parent.attr('class', function (i, c) {
                return c.replace(/(^|'s)col-lg-'S+/g, blockWidth[0]);
            });
            //console.log(ui.position)
            SavePortletDrop(sortdiv[2]);
        }
    });
