javascript - XMLHttpRequest is not working in QML Blackberry 10 -

in given code have used 1 label , 1 button . want when click on button request must sent json given link , print on label . code printing "ok" inside label upon success

the issue facing not getting if statement. on button clicked nothing happens. know there network manager in qt can use in situation want parse inside qml

// default empty project template import bb.cascades 1.0  // creates 1 page label  page {     container {         layout: stacklayout {}         label {             id: msglabel             text: qstr("hello world")             textstyle.base: systemdefaults.textstyles.bigtext             verticalalignment: verticalalignment.center             horizontalalignment: horizontalalignment.center         }         button {             id: requestxml             objectname: "requestxml"             onclicked: {                 var doc = new xmlhttprequest();                 doc.onreadystatechange = function() {                     if (doc.readystate == 4) {                         msglabel.text="ok"                         // pass “doc.responsetext” c++ parsing                     }                 }                 doc.open("get", "http://www.example.com/sample.json", true);                 doc.send();              }     }     } } 

in .pro file have declared

config += qt warn_on cascades10 qt += network config += debug config += console libs += -lbbdata qt +=script qt +=scripttools 

where wrong ? or have declare thing else

i don't have access twitter api, can't test you. work other json files. example need libs += -lbbdata in .pro file. also, read datasource , jsondataaccess. if download json through c++.

import bb.cascades 1.0 import bb.data 1.0  page {     container {         layout: stacklayout {         }         label {             id: msglabel             text: qstr("hello world")             textstyle.base: systemdefaults.textstyles.bigtext             verticalalignment: verticalalignment.center             horizontalalignment: horizontalalignment.center         }         button {             id: requestxml             onclicked: {                 datasource.load();             }         }         attachedobjects: [             datasource {                 id: datasource                 source: "https://api.twitter.com/1.1/statuses/user_timeline.json?include_entities=true&include_rts=true&screen_name=ladygaga"                 type: datasourcetype.json                  ondataloaded: {                     console.log("loaded");                     console.log(json.stringify(data)); //just testing                     console.log(data);                           }                 onerror: {                     console.log(errortype);                     console.log(errormessage);                 }             }         ]     } 

also twitter api using no longer available check rest api v1.1 resources or following error:

{"errors": [{"message": "the twitter rest api v1 no longer active. please migrate api v1.1. https://dev.twitter.com/docs/api/1.1/overview.", "code": 68}]}
