Ashutosh,

This is a difficult matter to tackle well, and there are many ways to do 
it.  One would be to dynamically generate the page with javascript objects 
holding the data that you will need conditionally.  Another, which 
unfortunately binds your users to IE 5.5+, is to utilize the MSXML parser 
and either dynamically generate XML islands in your page or use the 
XMLHTTP object to connect to a database to get your XML document, then 
query the document for your conditional data.  Benefits to this latter way 
include keeping your data better organized, easily validatable (via DTD 
and XSD), and easily transformable (via XSL) in complex ways.

Other ways to maintain rich client-side javascript data structures also 
almost certainly exist.

Good luck,

Tim
