[jQuery] Communication between two Jsps using Javascript

I m new to use Javascript.
I will really aprreciate if you take some time and clarify my doubt.
Here is the situation.
There is a 'Browse' hyperlink on the Parent jsp. As soon as, i click
the link, a new jsp Child jsp is opening with the values coming from
the backend. As the user selects some values in the Child jsp and say
'Add', the values should be transfered and displayed ( can be done by
creating dyanamic 'divs')to the Parent jsp. Here is the tricky one.
The Parent jsp should not refreshed.
I tried so hard to achive this, but failed miserably.
(Creation of dynamic divs is just a way to achive this)
Can you please help me out in this? Is there any other way, this
requirement can be achived?
