asp下去除数组中重复的项的方法

<%
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,die,dir,die")

%>

结果是：abc,dge,gcg,die,dir

如果是两个数组进行对比，去掉相同的数组元素：

?

<%

        Function mover(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 mover(n1,n2)

 

%>

 结果是：

3.数组A中有为空的元素(如a=array("ww","ss","","dd","","ee")),

 想把这些空元素从数组A中去掉.并把去掉空元素有的数组赋给数组B.

?

str=""

for i = lbound(A) to ubound(A)

if A(i)<>"" then

if i<>lbound(A) then str = str + "," end if

str = str & A(i)

end if

next

b = split(str,",")
