我在javascript中对一行进行了两次正则表达式检查
^(.*?(\b([A-Z]{2})([0-9]{7})\b)[^$]*)$
和
^(.*?(\b([A-Z]{3})([A-Z]{2})([0-9]{7})\b)[^$]*)$
问题是：
如果用户添加AAA AA1234567脚本检测第一个正则表达式而不是第二个。任何帮助如何解决这个问题？
答案 0 :(得分：0)
如果我正确理解了问题，则Option Explicit
Sub test()
'declaration
Dim ws1 As Worksheet, ws2 As Worksheet
Dim c1 As Range, c2 As Range, rng1 As Range, rng2 As Range, cfind As Range
'set worksheets
Set ws1 = ActiveWorkbook.Sheets(1)
Set ws2 = ActiveWorkbook.Sheets(2)
'define ranges to look in/for
With ws1
Set rng1 = .Range(.Cells(2, 2), .Cells(.Cells(Rows.Count, 2).End(xlUp).Row, 2))
End With
With ws2
Set rng2 = .Range(.Cells(2, 2), .Cells(.Cells(Rows.Count, 2).End(xlUp).Row, 2))
End With
'loop through the values in sheet 1
For Each c1 In rng1
'loop through the values in sheets 2
For Each c2 In rng2
On Error Resume Next
'look for the value from sheet 2, in sheet 1
Set cfind = c1.Find(what:=c2.Value, lookat:=xlPart, LookIn:=xlValues)
'is a partial match found? then copy the value from column sheet2-colA from c2 to sheet1-colA for c1
If (Not (cfind Is Nothing)) Then
c1.Offset(0, -1).Value = c2.Offset(0, -1).Value
End If
'emtpy the found range
Set cfind = Nothing
Next c2
Next c1
'SUCCESS!!
End Sub
文字应与两种模式相匹配。第一种模式已经奏效：
AAA AA1234567第二个模式只需要两个标记之间的空格，如下所示：
^(.*?(\b([A-Z]{2})([0-9]{7})\b)[^$]*)$
