With .AddSelect("dq","地区","|" & DataTables("可用车辆").GetComboListString("地区 ")) 有个多余空格

Case "getProducts.htm"
Dim vals As String
If e.PostValues.Count = 1 Then

msgbox(e.PostValues("dq")) ‘看看传入什么值

vals = "|" & DataTables("可用车辆").GetComboListString("网点","地区='" & e.PostValues("dq") & "'")
ElseIf e.PostValues.Count = 2 Then

Dim Filter As String = "地区='" & e.PostValues("dq") & "' And 网点='" & e.PostValues("wd") & "'"

msgbox(Filter ) ‘看看传入什么值
            vals = "|" & DataTables("可用车辆").GetComboListString("车牌", Filter)
        ElseIf e.PostValues.Count = 3 Then
            Dim Filter1 As String = "网点='" & e.PostValues("wd") & "' And 车牌='" & e.PostValues("cp") & "'"

msgbox(Filter1 ) ‘看看传入什么值
            vals = "|" & DataTables("可用车辆").GetComboListString("车架", Filter1)
        End If
        e.WriteString(vals)
