先贴出来 ajax代码

  function outto()    {        $("#showxz").hide()        if ($("#ids").attr("value") == "") {            alert('未选中任何数据');            return;        }        var a = $("#ids").attr("value");        var t = a.split(',');       //都完成了才可以显示下载文件名        if (confirm("您要操作的数据条数为 " + t.length + ",确认后继续？") == true) {            $("#ssj").val('......系统正在压缩中请稍后.....');            setTimeout(function () {             $.ajax({                type: "GET",                url: "/xxhz_admin/filemore/",                //temp：预防360缓存内容，保存iis的sessionID                data: { ids: a, temp: Math.random() },                async: true,//异步之后不影响本页其他功能                dataType: "json",                success: function (data) {                    if (data.name == '')                    {                        $("#ssj").val('......压缩完成.....');                        $("#showxz").show();                    }                   // alert(data.ret);                    //alert(data);                },                error: function (XMLHttpRequest, textStatus, errorThrown) {                    //alert(XMLHttpRequest.status);                    //alert(XMLHttpRequest.readyState);                    //alert(textStatus);                }            });            }, 1000);        }    }

后台代码，包含，目录操作和文件的操作，还有压缩，注意WinRAR程序所在的位置
