[Javascript] Array-Indexing Problem

Mon Sep 13 05:31:26 CDT 2004

Hi Tim,

Try this and it work fine 

var alias = eval('viewlist'+ index_num);

Mainly when you do the first alert alias is a string and it will still be
evaluated as a string on the third alert 
but by putting your string into an eval() you will then have the object.

Hi - please can you have a look at the script below. The first and second
Alerts work OK, but the third one fails. Why is that, and how can I correct
it ?
