How to pass a value from a Form to a Quick Create Form ?

We are using CRM2013 SP1 on premise.

I need to pass a value from a Form A (based on Entity A) to an Associated Quick Create Form B (based on Entity B) using javascript

The relationship between entity A and B is 1:N.  On the Form A there is a subgrid for Entity B. The requirement is to set some default values on the Quick Create Form B based on values from Form A. Is there a way to do this using javascript?

Many thanks
