How can I do pagination when downloading facebook posts via javascript and FB.api? -

i trying download facebook wall posts via javascript sdk. managed call first 25 posts, trouble when trying paging.next , feed new call using loop, , iterate on until no more pages available.

the code produces same page 10 times not understand. should give next page , next page , next page..?

fb.login(function(response){          // first call calls pagename/feed         fb.api(request, function (response) {              // prints log , declares x next page             console.log(response.paging.next);             var x = response.paging.next;              // loop preferably should continue until no more pages             // deal later             (i = 0; < 10; i++) {                  // calls x gives me rhe next page                 // reason code not manage change                 // x , new call                 fb.api(x, function (res){                      console.log(i);                     console.log(res.paging.next);                     // here respecify x                     x = res.paging.next;                      });                  };             }            );       }, {scope: 'publish_actions'}); 

you need learn how deal asynchronous javascript , how recursive functions. trying use "x" before asynchronous api call sets it. meaning, whole loop finishes before "x" gets set once - because api call takes while.

here´s quick code, did not test should show 1 solution:

var items = []; function apicall(next) {     fb.api(next, function (response) {         (var = 0; < response.data.length; i++) {             //add posts items array             items.push(response.data[i]);         }         if (response.paging && response.paging.next) {             //call function recursively until there no "next"             apicall(response.paging.next);         } else {             //this when it´s done             console.log(items);         }     }); } apicall('/page-id/feed'); 

make sure understand concepts, it´s important know when deal javascript sdk , javascript in general.
