I'm using the Javascript SDK for facebook to login a user with Facebook:

Documentation FB.Login: link

Unfortunatly this dialog is always in English.

FB.Dialog will trigger a popup window with url:

.php?PARAMETERS

With the help of another related question here I found that I can add locale2 parameter:

.php?PARAMETERS&locale2=es_ES

With this extra parameter the dialog is now shown in Spanish.

But I can't find how to pass this language paramter to the FB.Login function so it's also used in the login dialog.

Is there any function known that can help me with this issue?

It might be something to do with the SDK source you are using

From http://developers.facebook./docs/reference/javascript/

 js.src = "//connect.facebook/en_US/all.js";

Change en_US to your language locale es_ES and that might fix it.

You can set locale while loading Facebook SDK:

   // Load the SDK Asynchronously
    (function (d) {
        var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
        if (d.getElementById(id)) { return; }
        js = d.createElement('script'); js.id = id; js.async = true;
        js.src = "//connect.facebook/en_GB/all.js";
        ref.parentNode.insertBefore(js, ref);
    } (document));

As you can see, in link assigned to js.src there is en_GB part. If you want to load SDK with current user's locale, you can check the locale before loading SDK and then use this here.
