Specify the callback dataType

[JNajera]

It there's any way I can set the dataType for my callback at hello.login()? Because for some apps Im developing, i need to return it as JSON to my callback url.

Thanks in advance

Erm... the library only works with json for some very good reasons. Why, do you see something else?

Sorry I didn't explain it well. Im using Ruby on Rails with Devise, so for make it work manually without reload the page I need to post back on my callback_url as JSON.
This is an example using the FB JSDK (Sorry i only have it on coffeescript)

$(document).ready ->
  $("#facebook-connect").click (e) ->
    e.preventDefault()
    FB.login (response) ->
      if response.authResponse
        $.getJSON '/auth/facebook/callback', (data) ->
          # Do more stuff for login

When I use the hello.js library, the Hello.login() function do the callback, but I receive on my server the callback as dataType = "text/html"

Started GET "/auth/facebook/callback" for 127.0.0.1 at 2014-06-03 10:47:10 -0500
Processing by Devise::OmniauthCallbacksController#facebook as HTML

Instead im looking to mod the dataType of the ajax callback, only for the login method, like dataType = "application/json"

Started GET "/auth/facebook/callback" for 127.0.0.1 at 2014-06-03 10:49:14 -0500
Processing by Devise::OmniauthCallbacksController#facebook as JSON

I hope now its more clear. Thanks for your response.

Sorry its still hard to understand. If you want to change the xhr request in hello.api() then take a look at https://github.com/MrSwitch/hello.js/blob/master/src/modules/windows.js#L145

Since the OAuth flow works by opening pages with test/html, i fail to grasp what you mean when you say "post back on my callback_url as JSON.".
