javascript - AJAX get and callbacks -

i'm trying make variable depend on callback ajax function, however; can't seem working. want make sure defaults.context has value before proceeding other code.

what doing wrong or how can achieve in proper way?

var defaults = {      currentcase: undefined,      context: {}   }    // set defaults   function initdefaults(){      defaults.currentcase = getcurrentcase();      defaults.context = getcontext(defaults.currentcase, function(object){         console.log(object); // logs right data         return object;      });      console.log(defaults.context); // logs undefined   }    initdefaults();    // id of current case   function getcurrentcase(){      return global_vars.project_id;   }    function getcontext(id, callback){      var obj = {};       $.get(global_vars.template_url + "/includes/load-project-context.php?id=" + id, function(data) {         obj = json.parse(data);      }).complete(function() {         callback(obj);      });   } 

thanks in regards,

you can use like

global_vars.template_url + "/includes/load-project-context.php?id=" + id, function(data) {     obj = json.parse(data);  }).complete(function() {     callback(obj);  }).fail(function() {     callback(error);  }); 

this callback chaining. can use other callbacks handle other use cases.
