像页面输出脚本

 无异步的  js = "window.parent.onComplete(" + System.Convert.ToString(uploadInfo.State != "Stop").ToLower() + ");";                  }                  ScriptManager.RegisterStartupScript(this, typeof(progressUploads), "progress", js, true);

有异步的 ScriptManager.RegisterStartupScript(UpdatePanel1, typeof(UpdatePanel), "success", "alert('更新成功')", true);
