ajax - Kango Extension Cross Domain Request -

i'm new working kango , have setup basic extension already. conversion existing extension , far. however, docs feel little light when comes doing ajax call cross-domain.

this existing code worked 100% in other extension framework:

$.ajax({     url:url,                     success:function(data){        alert("success!")     } }); 

i'm seeing 200 ok response, response empty , never see alert.

i'm guessing comes down need use kango api? i've tried of documentation samples , nothing seems working. above inside content script, if matters. i'm trying pull file , read contents, seems more difficult should be.

if wan't perform cross domain request content script, should use kango.xhr.send:

kango.xhr.send({url: 'http://example.com/'}, function(data) {     if (data.status == 200 && data.response) {         kango.console.log(data.response);     }     else {         kango.console.log('something went wrong');     } });
