Question

How to set the JSTL variable value in java script?

Answer 1

Just don't. Don't write code with code. Write a JSON object or a var somewhere but for the love of a sensible HTTP divide, don't write JavaScript functions or methods hardcoded with vars/properties provided by JSTL. Generating JSON is cool. It ends there or your UI dev hates you.

Imagine if you had to dig into JavaScript to find something that was setting parameters in the middle of a class that originated on the client-side. It's awful. Pass data back and forth. Handle the data. But don't try to generate actual code.
