ajax 实现局部刷新


点击按钮刷新列表数据 ，求代码
------解决方案--------------------
这个应该使用框架吧...
------解决方案--------------------
求什么代码，显示区域可以套一个div，success返回后，直接根据id，改写id的innerhtml
------解决方案--------------------
比如一下代码，xxxx.ashx中可以处理要现实的内容，并返回给ajax的success,div1为层的id

         $.ajax({ 

              type: "POST",

              url: "xxxx.ashx",

              data:'CarNo='+escape(CarNo)+

                    '&CarName='+escape(CarName)+

                    '&CarMark='+escape(CarMark)+

                    '&Motorman='+escape(Motorman)+

                    '&Creator='+escape(Creator)+

                    '&CarType='+escape(CarType)+

                    '&Factory='+escape(Factory)+

                    '&FuelType='+escape(FuelType)+

                    '&EngineNo='+escape(EngineNo)+

                    '&Status='+escape(Status)+

                    '&Displacement='+escape(Displacement)+

                    '&SeatCount='+escape(SeatCount)+

                    '&Carrying='+escape(Carrying)+

                    '&BuyMoney='+escape(BuyMoney)+

                    '&BuyDate='+escape(BuyDate)+

                    '&VendorName='+escape(VendorName)+

                    '&VendorAddress='+escape(VendorAddress)+
