　　這個(gè)是js代碼主要在js代碼中紅色代碼部分設(shè)置了可以拖動(dòng)進(jìn)入時(shí)就排序，橙色代碼部分不太理解，好像沒(méi)用的樣子

復(fù)制代碼代碼如下:

$(function () {

    $("#catalog").accordion();

    $("#catalog li").draggable({

        appendTo: "body",

        helper: "clone",

        connectToSortable: "#cart ol"

    });

    $("#cart ol").sortable({

        items: "li:not(.placeholder)",

        connectWith: "li",

        sort: function () {

            $(this).removeClass("ui-state-default");

        },

        over: function () {

            //hides the placeholder when the item is over the sortable

            $(".placeholder").hide(); 

        },

        out: function () {

            if ($(this).children(":not(.placeholder)").length == 0) {

                //shows the placeholder again if there are no items in the list

                $(".placeholder").show();

            }

        }

    });

});

　　另外值得一提的是

.ui-state-default貌似是拖拽時(shí)內(nèi)置的一些類，對(duì)應(yīng)的還有
ui-state-hover等分別對(duì)應(yīng)當(dāng)有可以拖拽的對(duì)象在拖拽時(shí)，和拖拽到容器時(shí)的效果，本文代碼沒(méi)有體現(xiàn)。

以上就是關(guān)于jQueryUI中拖拽排序問(wèn)題的分析了，希望大家能夠喜歡。
