javascript - promise with ajax doesn't return any value in jquery -


my script:

var testapp = (function($){     var data = [{         "layout": "getsample",          "view": "conversations",          "format": "json",     }];      var data = 'default';     function ajaxcall(opt) {         return new promise(function(resolve, reject) {              jquery.ajax({                 method: "post",                url: localstorage.getitem("root")+"/index.php",                "data": opt,                error: function() {                    alert('error');                },                  success: function(result) {                    console.debug(result);                    resolve(result);                 }//end success           });//end ajax         });//end promise     }     return {          render: function(opt) {             if(typeof opt === 'object') {                 var list = {                     data : [opt]                 }                  //here i'm passing list object's data used in ajaxcall function.that's reeason used call method. it's data passed page.                 ajaxcall.call (list, list.data).then(function(v) {                      console.log("v "+v); // nothing happens yet...expecting success object passed here                 }).catch(function(v) {                     //nothing yet                 });               }         }      };//end return })(jquery);

is correct way of using promise ajax?

ajaxcall.call (list, list.data).then(function(v) {   console.log("v "+v); // doesn't return }).catch(function(v) { //nothing yet });

referred: how return response asynchronous call?

well, simple fix found.. //below line of code, moved above return new promise , worked

var opt = jquery.extend({}, data[0], opt[0]);
