Javascript – JSON serialization in Spidermonkey

javascriptjsonpythonspidermonkey

I'm using python-spidermonkey to run JavaScript code.

In order to pass objects (instead of just strings) to Python, I'm thinking of returning a JSON string.

This seems like a common issue, so I wonder whether there are any facilities for this built into either Spidermonkey or python-spidermonkey.
(I do know about uneval but that is not meant to be used for JSON serialization – and I'd rather avoid injecting a block of JavaScript to do this.)

Best Solution

I would use JSON.stringify. It's part of the ECMAScript 5 standard, and it's implemented in the current version of spidermonkey. I don't know if it's in the version used by python-spidermonkey, but if it isn't, you can get a JavaScript implementation from http://www.json.org/js.html.
