我建​​议您记录错误，而不是在服务器端显示消息框.
检查 google [

I would suggest you to log the errors instead of showing message box at serverside.
Check the google[^] links to know more.

我认为您忘记了单引号在警报方法中的消息字符串周围，

Response.Write("<script language=''javascript''>alert(''" + p + "'')</script>");

I think you forgot the single quotes around the message string in alert method,

Response.Write("<script language=''javascript''>alert(''" + p + "'')</script>");
