教你如何在asp下去除数组中的重复项

在查看asp编码的时候我们可以在其中发现有许多的数组重复项,但是一点点删除又太麻烦了,那么我们现在就让小编教你如何在asp下去除数组中的重复项吧。
 

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,",")

上文中介绍了教你如何在asp下去除数组中的重复项的内容,大家下次若是还需要除数组中的重复项就可以参照这些解决办法,基本上可以搞定。
