Controller 如何向view注冊js?比如添加新聞的信息時候 彈出對話框 提交成功 或失敗就是類似以前的ClientScriptManager cs = page.ClientScript;            Type cstype = page.GetType();            if (!cs.IsClientScriptBlockRegistered(cstype, cskey))            {                cs.RegisterClientScriptBlock(cstype, cskey, sb.ToString(), true);            }
