asp 数组 重复删除函数(脚本之家增强版)

因为要写个东西用到，所以百度了一下，居然有朋友乱写，而且比较多，都没有认真测试过，只对字符可以，但是对数字就不可以，而且通用性很差，需要修改才可以真正使用。没办法就自己写了，经过测试完全没有问题，而且思路很方便，代码很短，如下：

复制代码 代码如下:

<%
function cxarraynull(cxstr1,cxstr2)
if isarray(cxstr1) then
cxarraynull = "对不起，参数1不能为数组"
Exit Function
end if
if cxstr1 = "" or isempty(cxstr1) then
cxarraynull = "nodate"
Exit Function
end if
ss = split(cxstr1,cxstr2)
cxs = cxstr2&ss(0)&cxstr2
sss = cxs
for m = 0 to ubound(ss)
cc = cxstr2&ss(m)&cxstr2
if instr(sss,cc)=0 then
sss = sss&ss(m)&cxstr2
end if
next
cxarraynull = right(sss,len(sss) - len(cxstr2))
cxarraynull = left(cxarraynull,len(cxarraynull) - len(cxstr2))
end Function
%>

复制代码 代码如下:

<%
function cxarraynull(cxstr1,cxstr2)
if isarray(cxstr1) then
cxarraynull = "对不起，参数1不能为数组"
Exit Function
end if
if cxstr1 = "" or isempty(cxstr1) then
cxarraynull = "nodate"
Exit Function
end if
do while instr(cxstr1,",,")>0
cxstr1=replace(cxstr1,",,",",")
loop
if right(cxstr1,1)="," then
cxstr1=left(cxstr1,len(cxstr1)-1)
end if
ss = split(cxstr1,cxstr2)
cxs = cxstr2&ss(0)&cxstr2
sss = cxs
for m = 0 to ubound(ss)
cc = cxstr2&ss(m)&cxstr2
if instr(sss,cc)=0 then
sss = sss&ss(m)&cxstr2
end if
next
cxarraynull = right(sss,len(sss) - len(cxstr2))
cxarraynull = left(cxarraynull,len(cxarraynull) - len(cxstr2))
end function
%>

复制代码 代码如下:

s="1,2,3,4,55,55,55,333,333,2,3,5,3,88,,,,,,,66,,66,,,,,,,,,,,,,,,,,,,,,,,,"
s=cxarraynull(s,",")
response.write s
