有没有其他办法实现？？

如何在服务端赋值，并且如何在客户端读取，能有例子吗？对asp我不是很熟悉

Response.Write("<script language='javascript'>var i='")
Response.Write(Session("OK"))
Response.Write("';")
Response.Write("alert(i);")
Response.Write("</script>")
%>
嗯,客户端能取Session真是一个有趣又疯狂的想法,那以后不是可以为所欲为了?

直接做没有办法，因为session是服务器端，而javascript运行在客户端，不能得到服务器端变量，但是你可以设一个type=hidden的input，加上runat=server,使之可在服务器端处理，当你得到session的数值时，便对input赋值，就可以把session的数值放到客户端来处理了
