How to pass JSONObject to JavaScript function during on change event in html

I am populating a JSONObject from backend java and setting it to variable in jsp.

I need to pass the variable to JavaScript function during onchange event.

I am getting syntax error during onchange due to quotes present in the JSONObject.

If I populate as a Map in backend java and I can able to set it to a variable in jsp and pass to JavaScript function successfully.

My question?

1. Shall we pass the JSONObject in onchange event as mentioned above. If yes what could be the syntax.

I used onchange="getCountries('${countryJSON}')" which is not working.

2. If we escape the quotes in JSONObject, is it possible to parse the JSONObject in JavaScript function.

3. Any alternative approach for this issue.
