Question

asp 字符串中插入字符串

aa="1,2,4,6,7,8"
split(aa,",")(0) 为 1
split(aa,",")(1) 为 2
split(aa,",")(2) 为 4
...
我想在split(aa,",")(1)前面插入字符串，应该如何写呢

Answer 1

<%
aa="1,2,4,6,7,8"

arr = split(aa,",")
DIM arr1()
REDIM arr1(ubound(arr)+1)

for i = 0 to ubound(arr)+1
if i = 0 then
arr1(i) = arr(i)
else
if i = 1 then
arr1(i) = "xxxx"
else
arr1(i) = arr(i-1)
end if
end if
response.Write arr1(i)&"<br>"
next
response.End()
%>

Answer 2

'假设需要插入的字符串是“￥”
s="￥"
aa="1,2,4,6,7,8"
aa=Mid(aa,1,1)&","&s&Mid(aa,2,Len(aa)-1)
response.write aa
