主题：WEUI如何获取到列表输入的值进行编辑。

我是使用帮助中“动态列表项目三”内的代码来实现记录的添加功能，现在想在“编辑”功能页中读取这些数据到列表框中，并保留级联的功能，应该怎么改？

HttpRequest事件代码：

Select Case e.Path
    Case "test.htm"
        Dim wb As New weui
        wb.AddForm("","form1","test.htm")
        With wb.AddInputGroup("form1","ipg1","动态列表")
            With .AddSelect("xh","型号","|" & DataTables("表A").GetComboListString("型号"))
                .Attribute = """
            End With
            With .AddSelect("gg","规格","")
                .Attribute = """
            End With
            .AddSelect("ys","颜色","")
        End With
        With wb.AddButtonGroup("form1","btg1",True)
            .Add("btn1", "确定", "submit")
        End With
        e.WriteString(wb.Build) '生成网页
    Case  "getProducts.htm"
        Dim vals As String
        If e.PostValues.Count = 1 Then
            vals  = "|" & DataTables("表A").GetComboListString("规格","型号='" & e.PostValues("xh") & "'")
        ElseIf e.PostValues.Count = 2 Then
            Dim Filter As String = "型号='" & e.PostValues("xh") & "' And 规格='" & e.PostValues("gg") & "'"
            vals = "|" & DataTables("表A").GetComboListString("颜色", Filter)
        End If
        e.WriteString(vals)
End Select
