Having troubles extracting json data within javascript

I am having some difficulty extracting json data from a returned hash table.

From the geocode data that is returned the following   console.log(data)   console.log(data["latitude"])

Results in:   {"latitude": "55.272766", "longitude": "-114.762116"}   undefined

Checking a javascript created hash   var foo = {"foo": "footoyou", "bar": "barandbeyond"}   console.log(foo)   console.log(foo["foo"])

Shows me   Object foo=footoyou bar=barandbeyond   footoyou

So obviously the json data is not is a json form, but rather just text.

Here is my controller code, where coords is the hash table   respond_to do |format|     format.js { render :json => coords.to_json, :layout => false}   end

I am getting the exact same output if I use :json => coords.to_json or just :json => coords

Help is appreciated.

Just after I post I find that the following works   console.log(eval('(' + data + ')'))

Is there a cleaner way of doing this?

if you are using prototype you could use data.evalJSON(true)
