I am currently trying to use AJAX in my application via jRails. I am trying to return a
JSON object from my controller, and then parse it in my Javascript. I am using json2.js to do the parsing.
Here is the code I currently have:
function getSomething()
{
$.ajax({
type: "GET",
url: "map/testjson",
success: function(data) {
var myData =
JSON.parse(data[0]);
window.alert(myData.login);
}
});
}
and in the controller:
class Map::MapController < ApplicationController
def index
end
def testjson
@message = User.find(:all)
ActiveRecord::Base.include_root_in_json = false
respond_to do |w|
w.
json { render :json => @message.to_json }
end
end
end
The window.alert simply says 'undefined' (without tics).
However, if I change the javascript to window.alert(data) (the raw object returned by the controller) I get:
[{"salt":"aSalt","name":"",
"created_at":"2010-03-15T02:34:25Z","remember_token_expires_at":
null,"crypted_password":"aPassword",
"updated_at":"2010-03-15T02:34:25Z","id":1,"remember_token":null,
"login":"zgwrig2","email":"
[email protected]"}]
This looks like an array of size 1, if I'm looking at it correctly, but I have tried just about every combination of
JSON.parse on the data object that I can think of, and nothing seems to work.
Any ideas on what I'm doing wrong here?
