C#後臺調用js方法無效果，未解決。

this.Page.ClientScript.RegisterStartupScript(this.Page.GetType(), "", "<script>Ceshi();</script>", true);

這句代碼與下麵這段代碼放一起，不管是插在哪裡，這句代碼都無效，無法調用js

註釋掉

Page.Response.Clear();

Page.Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(Path.GetFileName(filepath), System.Text.Encoding.UTF8));
Page.Response.AppendHeader("Content-Length", fiOutFile.Length.ToString());

就可以調用js,但是下麵這段導出excel的代碼就異常了。

求解。。。。

FileInfo fiOutFile = new FileInfo(filepath);
Page.Response.Clear();
Page.Response.ClearHeaders();
Page.Response.Buffer = false;
Page.Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(Path.GetFileName(filepath), System.Text.Encoding.UTF8));
Page.Response.AppendHeader("Content-Length", fiOutFile.Length.ToString());
Page.Response.WriteFile(fiOutFile.FullName);
fiOutFile.Delete();
Page.Response.Flush();
Page.Response.End();
