因为同时还有其他条件

    If dr1 IsNot Nothing 
if  dr1("申读学校")>"" And dr1("申读班级")>""
        Dim sdxx =.AddInput("申读学校","申读学校:","Text")
        sdxx.readonly = True
        sdxx.value= dr1("申读学校")
        Dim sdbj = .AddInput("申读班级","申读班级:","Text")
        sdbj.readonly = True
        sdbj.value= dr1("申读班级")
endif
    Else
        messagebox.show("问题2")
        Dim sdxx =.AddInput("申读学校","申读学校:","Text")
        sdxx.readonly = True
        sdxx.value= e.Cookies("sdxx")
        Dim sdbj = .AddInput("申读班级","申读班级:","Text")
        sdbj.readonly = True
        sdbj.value= e.Cookies("sdbj")
