jQuery Ui 拖拽排序实现
感觉使用jqueryUi 进行拖拽排序比箭头移动排序要爽多了，实现了下跟大家分析下：
1 使用 jquery ui控件的 drag功能
2 实现拖拽，拖拉位置
3 循环读取当前位置的id
4 ajax到后台，依次找到位置的id 然后修改sequence

<script type="text/javascript">var params={};$(function() { $( "#recommendBar" ).sortable({revert: true});$( "#draggable" ).draggable({connectToSortable: "#recommendBar",helper: "clone",revert: "invalid"}); $( "#sore" ).click(function() {$(".recomend_list .barMoving div").each(function(i){ var vals= $(this).attr("id"); var valu=i+1; var param="L"+valu; params[param]=vals+""; });$.post("<@ofbizUrl>recommendSore</@ofbizUrl>",params,ajaxFormCallback); });});</script><ul id="recommendBar" id="${product.getString("productId")?if_exists}"></div> </ul>?
