Question

I’m trying to send a Python list in to client side (encoded as JSON). This is the code snippet which I have written:

array_to_js = [vld_id, vld_error, False]
array_to_js[2] = True
jsonValidateReturn = simplejson.dumps(array_to_js)
return HttpResponse(jsonValidateReturn, mimetype='application/json')

How do I access it form client side? Can I access it like the following?

jsonValidateReturn[0]

Or how do I assign a name to the returned JSON array in order to access it?

Actually I’m trying to convert a server side Ajax script that returns an array (see Stack Overflow question Creating a JSON response using Django and Python that handles client side POST requests, so I wanted the same thing in return with Python, but it didn’t go well.

If both client and server are in Python, here’s what you need to know.

Server. Use a dictionary to get labels on the fields. Write this as the response.

>>> import json
>>> json.dumps( {'vld_id':1,'vls_error':2,'something_else':True} )
'{"vld_id": 1, "something_else": true, "vls_error": 2}'

Client. After reading the response string, create a Python dictionary this way.

>>> json.loads( '{"vld_id": 1, "something_else": true, "vls_error": 2}' )
{u'vld_id': 1, u'something_else': True, u'vls_error': 2}
