Trouble with displaying JSON array

Question

could you please help me figure out why I'm getting "undefined" instead of the value.

As it is plain to see I'm having trouble getting the data from the array, in firebug I get this as a response....

{"status":"success",
 "response":[
    {"email":
        {"email":"xxxxx@iing.mxl.uabc.mx",
         "valid":"1",
         "reason":null,
         "confirmed_at":"0000-00-00 00:00:00",
         "contact_email":"1",
         "login_email":"1",
         "users_id":"6375"},
     "history":[
        {"contactRole":"Non Classified Lead with History",
         "contactProject":"2082",
         "contactBrand":"B"},
        {"contactRole":"co Author",
         "contactProject":"32",
         "contactBrand":"B"},
        {"contactRole":"co Author",
         "contactProject":"176",
         "contactBrand":"B"},
        {"contactRole":"co Author",
         "contactProject":"582",
         "contactBrand":"B"},
        {"contactRole":"co Author",
         "contactProject":"1858",
         "contactBrand":"B"},
        {"contactRole":"Author",
         "contactProject":"12",
         "contactBrand":"J"},
        {"contactRole":"Editor",
         "contactProject":"176",
         "contactBrand":"B"}]},
    {"email":
        {"email":"xxxxx@hotmail.com",
         "valid":"1",
         "reason":null,
         "confirmed_at":"0000-00-00 00:00:00",
         "contact_email":"0",
         "login_email":"0",
         "users_id":"6375"},
     "history":[]}]}

this is the code referring to my javascript file http://pastebin.com/gPaEAKim

snapshot of the view that I'm getting.

Just to be on the safe side...this is the way the array looks like when I debug it from the controller

    Array

Answer 1

If your data var in your JS code is the entirety of the JSON response, then you're working one level too high, and the inner loop is working 2 levels too high:

$.each(data['response'], function(i, email) { 
           ^^^^^^^^^^^^--- missing this

      $.each(email, function(ii, ...)) {

as your code stands now, the inner loop's email is overwriten your outer loop's as well.
