post 加返回判断

  var url = "@Url.Action("PdfSee")";
            var param={
                path:"aaa"
            };
            $.post(url,param, function (result) {
                var swfpath = "@Url.Content("~/")" + result;
                pdfsee(swfpath);
                var delurl="@Url.Action("PdfDel")";
                var data = { swfpath: result };
                $.post(delurl, data, function (result) { });
            });
