asp下去除数组中重复项的方法

这篇文章主要为大家介绍了asp中去除数组中重复项的方法，需要的朋友可以参考下
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：
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.
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,",")
