JQuery拖拽排序

1,引用JqueryUI

$(function(){
	$(".m_title").bind('mouseover',function(){
		$(this).css("cursor","move")
	});
	

    var $orderlist = $("#orderlist");
	var $list = $("#module_list");	
	$list.sortable({
		opacity: 0.6,
		revert: true,
		cursor: 'move',
		handle: '.m_title',
		update: function(){
			//不用次都去请求
                },
                success: function(msg) {
                     //alert(msg);
					
                }
             });
		}
	});
})

2,最后拼json 传到后台(避免用tr td)

 function addSection(title, id) {

        var objUl = $("#firsttr");

        var objLi = $("<li class='m_title' ></li>");

        objUl.append(objLi);

        objLi.append("<div class='fl' style='cursor:move;'><p style='position:relative;'><input type='text' value='" + title + "' class='box-shadow-n-d'/></p></div>");

        var obj = $("<a href='javascript:void(0);' class='pic-a-r' style='top: 16px; right: -10px;text-indent:-9999px;'>删除</a>").attr("sectionId", id);

        objLi.find("p").append(obj);

        var sectionId = obj.attr("sectionId") ? obj.attr("sectionId") : "";

        obj.click(function () {

            var $this = $(this);

            if (sectionId != "") {

                art.dialog.confirm('你确定要删除这掉消息吗？', function () {

                    $this.gkPostJson({

                        url: "",

                        data: { "courseId": window.pageConfig["CourseId"], "sectionId": sectionId },

                        success: function (data) {

                            showTips("操作成功");

                            objLi.remove();

                        }

                    });

                }, function () {

                    //art.dialog.tips('执行取消操作');

                });          

            } else {

                objLi.remove();

            }

            

        });

    }
