Using jQuery/JS in Lua

I am accessing entire form data with "luci.http.formvalue()". It will give me all input values with or without change. Instead, want to set only changed values in config among N number of input fields.
It is possible to filter the changed form fields in jQuery but not able to get this in Lua code.
Is there any way in Lua to achieve this? Or Can jQuery be used in Lua and how to use?
