I''m having trouble dealing with my server response using Prototype
1.5. My server is returning the results of Ajax queries in JSON (An
array) and I need to eval() that in my Ajax.Request onSuccess.
Unfortunately, I cannot find a way to do so.
How can I get something like this:
{"Success":true,"Success_Message":"Yay, PHP script
returned
something..."}
into an array var in my Ajax.Request that would read like so:
Results["Success"]
Results["Success_Message"]
Thanks.

I was having a similar problem and the only solution I could come up
with is to use an eval (which admittingly, I don''t like to use if at
all possible).
This should work:
var jsonStr =
''{"Success":true,"Success_Message":"Yay, PHP
script
returned something..."}'';
var Results = eval(''('' + jsonStr + '')'');
Hope that helps! Cheers!

If you''re using the Ajax.Request object, then you can use the second
parameter of the callback function. However, you have to specifiy the
x-json header on the server with a value of your json object. I
suspect, that somewhere in the prototype code, all it''s doing is an
eval() of the x-json header, but it obfuscates those details from the
code.
For example, in PHP, instead of simply echoing
{"Success":true,"Success_message":"Yeah!"} you
would say:
header("x-json",
''{"Success":true,"Sucess_message":"Yeah!"}'');
Then, you callback function could do something like this:
function callback(response, json) { if(json.Success)
alert(json.Success_Message) }
Does that help?

Hi, You may also want to have a look at the upcoming JSON support. It''s available here: http://svn.rubyonrails.org/rails/spinoffs/prototype/branches/ajax/ I''d like to get as much feedback as possible... So let me know how it goes. (there''s more info on the API in trac: http://dev.rubyonrails.org/ticket/7427 and http://dev.rubyonrails.org/ticket/7295) Regards, Tobie --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.
