老师  你好

移动端使用以下代码，在表中录入数据，经常出现的问题是，点一次确定按钮，连续增加好几条重复的数据。请老师给看看代码，有什么问题吗？  

 Case "ckpc.htm"
        If e.PostValues.Count = 0 Then
            wb.AddForm("","form1","ckpc.htm")
            With wb.AddInputGroup("form1","ipg1","出库批次录入")
                With .Addinput("出库日期","出库日期","date")
                    .Attribute = """
                End With
                With .AddSelect("排单顺序","排单顺序","")
                    .Attribute = """
                End With
                .AddSelect("产品名称","产品名称","")
                .AddInput("数量","数量","number")
                .AddInput("托盘流水号","托盘流水号","Text")
                .AddInput("详细批次2","手工批次","Text")
            End With
            With wb.AddButtonGroup("form1","btg1",False)
                .Add("btn1", "确定", "submit")
                .Add("btn2","首页","" ,"default.htm")
            End With
            e.WriteString(wb.Build) \'生成网页
        Else
            Dim nms() As String = {"出库日期","排单顺序","产品名称","数量"}
            For Each nm As String In nms
                If e.PostValues.ContainsKey(nm) = False Then \'生成错误提示页
                    With wb.AddMsgPage("","msgpage","增加失败", nm & "列不能为空!")
                        .icon = "Warn" \'改变图标
                        .AddButton("btn1","返回").Attribute = ""
                    End With
                    e.WriteString(wb.Build)
                    Return \'必须返回
                End If
            Next
            nms = New String() {"出库日期","排单顺序","产品名称","数量","托盘流水号","详细批次2"} \'重新定义了nms数组,增加了两列.
            Dim dr As DataRow = DataTables("出库批次台账").AddNew()
            For Each nm As String In nms
                If e.PostValues.ContainsKey(nm) Then
                    dr(nm) = e.PostValues(nm)
                End If
            Next
            dr.save()
            With wb.AddMsgPage("","msgpage","增加成功", "") \'生成成功提示页
            .AddButton("btn1","继续增加","ckpc.htm")
            End With
            e.WriteString(wb.Build)
        End If
