Populating HTML select using JSON

Hello,
I have 3+ HTML Select inputs(Dropdowns) on one HTML. After changing one of them I want to update select options in other dropdowns based on the selection.
I am using Prototype to execute the AJAX call. I worked it out for two dropdowns wherein Ajax response contained only values for one of the dropdowns.
I am planning to send back values for all dropdowns in one server hit. I was looking at probable solutions, JSON being one of them.
I know that if I can send the JSON objects from server side I can use them to populate the Dropdown boxes.
The thing I want to know is there anyway in Prototype library/HTML DOM that can take JSON Array as an input to populate the HTML Select.

No. You'll need to iterate through the data and construct the option elements.
