Not really a javascript guy, but how about using
document.thisform.index.value++ instead of index++ .
I believe index++ would be referencing a javascript
variable local to the PageNext function.

Subject: How to transfer information between JSP and Javascript?
> I have a question about transfer information between JSP and Javascript.
I have a Vector variable,it has several values,such as
"Peter","John","Kate". I show it in the table and show one each time.I
provide a link,when click this link,show next value.For example: first time
show "Peter",when I click this link,it shows "John" and so on.But I
encounter a question.I don't know how to transfer value back to JSP. I write
code to realize it,but when I click link,I found the value don't changed!
Why?
