Javascript string to array/dictionary

Question

How can i convert a string like this:

"{u'value': {u'username': u'testeuser', u'status': 1,
 u'firstName': u'a', u'lastName': u'a', u'gender': u'a',
 u'date': u'2013-03-06T09:01:27.939007',
 u'id': u'b1dab21bef3f3fd050d7c2f3e8006045'},
 u'key': u'2013-03-06T09:01:27.939007'}"

to something like a list that i can find info like data['value'] or data['username'] ?

i've tried to use substr and split methods but i think its not a widespread solution. — David R

"something like a list" you are probably looking for associative arrays — gordonk

It looks a bit like a JS object literal, but those u' delimiters disturb it. How did you got that? — Bergi

@Bergi It is stringifying of Python dictionary (wrong approach of serialization). — VisioN

Your string looks like you've wrongly serialized your dictionary. To pass data (e.g. dictionary, list, etc) to the client side you need to serialize it in JSON format.

In order to do this in your Python code you should use json.dumps(dict) from json package, while in the client side you need to apply JSON.parse(data) to load the data back.

with some modifications, i could send the serialized object correctly using the method you said! Thanks ;)

use eval()
like, I need to convert string of list-dict to list
by using eval("[{'range_type': '__to', 'value': '710'}, {'range_type': '__from', 'value': '700'}]") i got this: [{'range_type': '__to', 'value': '710'}, {'range_type': '__from', 'value': '700'}]
