maintain value of variable outside function in javascript? -


i try manipulate variable inside function. seems forget values once exit function, eventhough variable declared outside function.

the essential code:

var posts = {};                              // perform data request             // skjutsgruppens-page             $.oajax({                 url: "https://graph.facebook.com/197214710347172/feed?limit=500",                     *snip*                     success: function(data) {                     $.extend(posts, data);                 }             });               // gruppen             $.oajax({                 url: "https://graph.facebook.com/2388163605/feed?limit=500",                 *snip*                 success: function(data) {                     $.extend(posts, data);                 }             });

the oajax retrievies data facebook. want make variable contains data both oajax methods.

the actual code: http://eco.nolgren.se/demo/resihop/#

the issue success function executes @ arbitrary time in future--unless access posts after know success function has executed, receive undefined results, dependent on function , access timing.

the best approach handle correctly doing necessary work inside in success function, or use jquery's .when function.
