How use Facebook Javascript SDK response in Ajax request?

Supposing I have the foll开发者_如何学编程owing code which returns a Javascript object which I can read in Firebug's console:

FB.api('/me',function(apiresponse){
    console.log(apiresponse);
}); 

How can I then use the data from apiresponse in an Ajax request on the same page?

Currently my Ajax request looks as follows:

$.ajax({
    // CodeIgniter URL
    url: "<?=site_url?>('login/add_fb_users'); ?>",
    type: 'POST',
    data: apiresponse,
    success: function(data) {
        alert(data);
    }
});     

I know very little about Javascript, but reading around the subject leads me to think I have to convert the Javascript object to a JSON string. Is that correct? Am I on the right track?

You could put your AJAX call inside the handler for the API call like below..

FB.api('/me', function(apiresponse){
    console.log(apiresponse);

    $.ajax({
        // CodeIgniter URL
        url: "<?=site_url?>('login/add_fb_users'); ?>",
        type: 'POST',
        data: apiresponse,
        success: function(data) {
            alert(data);
        }
    });
});

one possible way:

• define a global variable in your javascript, e.g. var myVar1;
• set apireponse to the global variable in your FB.api callback (i.e. where u call console.log)
• reference the var myVar1 in your ajax fcn.
