excel如何实现下拉框复选?
EXCEL选择下拉框实现复选
第一步:新建一个excel且设置数据有效性【选中X列–数据–有效性】
第二步:开发工具–查看代码–把代码复制进去保存就OK了
代码如下:
Private Sub Worksheet_Change(ByVal Target As Range)' Developed by Contextures Inc.' www.contextures.comDim rngDV As RangeDim oldVal As StringDim newVal As StringIf Target.Count > 1 Then GoTo exitHandler On Error Resume NextSet rngDV = Cells.SpecialCells(xlCellTypeAllValidation)On Error GoTo exitHandler If rngDV Is Nothing Then GoTo exitHandler If Intersect(Target, rngDV) Is Nothing Then 'do nothingElse Application.EnableEvents = False newVal = Target.Value Application.Undo oldVal = Target.Value Target.Value = newVal If Target.Column = 7 Then '这里规定好哪一列的数据有效性是多选的,A列是第1列,依次类推,如3就是C列,7就是G列 If oldVal = "" Then 'do nothing Else If newVal = "" Then 'do nothing Else If InStr(1, oldVal, newVal) <> 0 Then '重复选择视同删除 If InStr(1, oldVal, newVal) + Len(newVal) - 1 = Len(oldVal) Then '最后一个选项重复 Target.Value = Left(oldVal, Len(oldVal) - Len(newVal) - 1) Else Target.Value = Replace(oldVal, newVal & ",", "") '不是最后一个选项重复的时候处理逗号 End If Else '不是重复选项就视同增加选项 Target.Value = oldVal & "," & newVal' NOTE: you can use a line break,' instead of a comma' Target.Value = oldVal _' & Chr(10) & newVal End If End If End If End IfEnd If exitHandler: Application.EnableEvents = TrueEnd Sub
