Specify the callback dataType about hello.js

[MrSwitch]

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.".
