Return javascript data to html/php from prompt

Question

My code makes a call to a service called OneID. The code is javascript and it prompts you to authorize the sharing of your email address (stored in the OneID repository) with a site.

OneID Prompt

I need the email address to be returned to the parent page if the user clicks, "OK".

Right now, all I can get it to do is generate a javascript Alert.

Note If you decide to help with this, you'll need to create a OneID account, sorry.

    <script src="https://api.oneid.com/form/form.js" type="text/javascript"></script>';

    echo '<script type="text/javascript">

    OneIdExtern.registerApiReadyFunction(
        function(){
            OneId.getUserAttributes(
                {
                    attr: "email[email]", 
                    authLevel : null, 
                    selectCards : true,
                    forceSelectCards : true
                },
                function(data){ 
                    if (data.attribute_data.email.email) {
                        <<-- somehow send data back to page? -->>
                    }
                }   
            );
        }
    );
    </script>';

don't use a prompt, use a modal with an `` for the address, and a ` — Mike 'Pomax' Kamermans, Jun 17 '13 at 11:59
Assuming the email address is in the data returned by OneID, you can call your own function with that data and/or make an ajax-call to a specific document on your server and send the email address as data with that request. It depends on what exactly you want to do with that email address. — Sumurai8, Jun 17 '13 at 12:04
@Sumurai8 -- yes, I actually need to take the email address and curl it to a site within a php environment. — Dan, Jun 17 '13 at 13:53

I suspect your problem is to inform your backend of the email that have just been entered. I see 2 way to do this:

If user have a form to validate as a next step, just prepare a Hidden field and store the email in there. It will be posted when the form will be validated
In real time, you can write a script on your server and call it with the email using Jquery (at the place you put you comment: <<-- somehow send data back to page? -->>). If you need to matchwith server information, put you'll probably need to maintain a session.

On more remark: if not constraints by cross domain issue, you can make your call directy in javascript instead of curling from your backend.
