Hi Buddies, My views regarding this topic are somewhat different. I think it is not good to reload the page every time you want to access the next element in the array.
The reason of "index" not getting auto-incremented is that array is being constructed on Server side. So every time page is getting re-loaded using PageNext() function. So a better solution will be to store the array on the page or in Session and access that array using Javascript without re-loading the page. Hope that helps.

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. ----- Original Message ----- From: "Edward King" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Saturday, March 22, 2003 10:38 PM 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!
