一个多选的变量i得到结果如下；
i=1,2,3,,5,6,,8
说明第4和第7个没选中。
用哪个函数可以将i结果变为；
i=1,2,3,5,6,8
 
不知表达的对不对,对这些不是太了解,请帮忙,谢谢!!

请帮忙,谢谢,急事...

<%
i="1,2,3,,5,6,,8"
i=Replace(i,",,",",")
Response.Write(i)
%>

如果是多个呢，并不一定是两个啊，

<%
i="1,2,3,,5,6,,,9,,11,,,,15"
for n=1 to len(i)
if instr(i,",,") then
i=Replace(i,",,",",")
end if
next
Response.Write(i)
%>

哈哈，谢谢楼上的，这样可以了
如果左边或右边的第一个字符是,号
要把他替换成空怎么写啊．．

谢谢madpbpl，这个再解决就ＯＫ了

好了，晕，刚才中间有个空格，现在可以了，谢谢．．

while instr(str,",,")
 str=replace(st,",,",",")
wend
if left(str,1)="," then str=right(str,len(str)-1)

谢谢multiple1902..你这方法好．．

Dim Str,tStr,TAry,i
Str="1,2,3,,5,6,,8"
tStr=Replace(Str,",,",",Null,")
TAry=Split(tStr,",")
For i=0 To UBound(TAry)
   IF TAry(i)=="Null" Then
      Response.Write "第"&i&"道题没有选中"
   End IF
Next
