小技术(ASP.NET)

一:在页面中使用隐藏字段的方法:
     a:定义隐藏字段
                registerhiddenfield(变量名, 初始值)
     b:在运行中设置隐藏字段的内容
                javascript:document.forms[0].变量名.value='';document.forms[0].submit;
     c:取得隐藏字段的值
                request.form(变量名)

     例:page_load....

          registerhiddenfield("__hidefield","")

          if not request.form("__hidefield") is nothing then
          response.write(request.form("__hidefield"))
          end if
          -----------------------------------------------------------------------------------
         在需设定隐藏字段内容的方法中
          dim setvalue as string
          setvalue = "<script>document.forms[0].__hidefield.value='fsvision';" _
                           & " document.forms[0].submit;</script>"
          page.registerstartupscript("setvalue ", setvalue )
