Hello,
I am using Ajax.Request to retrieve a JSON object from my server.
The result looks something this:
{"customers":{"342":"Mark","432":"John","522":"Mary","121":"Tom"}}
I parse the returned JSON data with " var mydata
transport.responseText.evalJSON(true); " to get an object.
So how can I can now loop though the object to access each key / value
pair and do something with it?
I am assuming that I don''t know the keys, so I need to read out the
keys as well.
I tried using .each without any success...
Any ideas?
greg

If you want to use it create a Hash object first out of your JSON. $H(mydata).each(...) -- Michael Peters Developer Plus Three, LP --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.
