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:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 | Private Sub Worksheet_Change(ByVal Target As Range) ' Developed by Contextures Inc. ' www.contextures.com Dim rngDV As Range Dim oldVal As String Dim newVal As String If Target.Count > 1 Then GoTo exitHandler ?? On Error Resume Next Set rngDV = Cells.SpecialCells(xlCellTypeAllValidation) On Error GoTo exitHandler ?? If rngDV Is Nothing Then GoTo exitHandler ?? If Intersect(Target, rngDV) Is Nothing Then ???'do nothing Else ??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 If End If ?? exitHandler: ??Application.EnableEvents = True End Sub |
