asp下去除数组中重复项的方法

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

　　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)

　　For k=0 To UBound(a)

　　If a(k)<> "" Then

　　If dic.Exists("_" & a(k)) Then

　　dic.Remove "_" & a(k)

　　End If

　　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
