asp下剔除数组中重复项的方法

导读：复制代码代码如下:

<%

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

复制代码代码如下:

<%

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：

复制代码代码如下:

<%

        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.

复制代码代码如下:

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,",")
