The code copy is as follows:
<%
Function MoveR(Rstr)
Dim i, SpStr
SpStr = Split(Rstr,",")
For i = 0 To Ubound(Spstr)
If I = 0 then
MoveR = MoveR & SpStr(i) & ","
Else
If instr(MoveR,SpStr(i))=0 and i=Ubound(Spstr) Then
MoveR = MoveR & SpStr(i)
Elseif instr(MoveR,SpStr(i))=0 Then
MoveR = MoveR & SpStr(i) & ","
End If
End If
Next
End Function
response.write MoveR("abc,abc,dge,gcg,dge,gcg,dge,gcg,die,dir,die")%>
The result is: abc,dge,gcg,die,dir
If you compare two arrays, remove the same array elements:
The code copy is as follows:
<%
Function move(farray,sarray)
a = Split(farray, ",")
Set dic = CreateObject("Scripting.Dictionary")
For k=0 To UBound(a)
If a(k)<> "" Then dic.Add "_" & a(k), a(k)
Next
a = Split(sarray, ",")
For k=0 To UBound(a)
If a(k)<> "" Then
If dic.Exists("_" & a(k)) Then
dic.Remove "_" & a(k)
End If
End If
Next
items = dic.Items()
Set dic = Nothing
moveR=Join(items, ",")
End Function
n1 = "a,b,1,11,12,13,14,15,16,17,19,20,22"
n2 = "a,1,12,14,18,19,20"
response.write move(n1,n2)
%>
turn out:
3. There are empty elements in array A (such as a=array("ww","ss","dd","","ee")),
I want to remove these empty elements from array A. and assign the arrays that have removed empty elements to array B.
The code copy is as follows:
str=""
for i = lbound(A) to ubund(A)
if A(i)<>"" then
if i<>lbound(A) then str = str + "," end if
str = str & A(i)
end if
next
b = split(str,",")
