please find code snippet below.

        $.ajax({         url: targeturl,         headers: reqheaders,         type: 'post',         data: reqformwithdatafile,         async: false,         cache: false,         datatype: 'jsonp',         usedefaultxhrheader: false,         processdata: false,         success: function (response) {                  alert('file upload successful');          },         error: function (jqxhr, exception) {             var msg = '';             if (jqxhr.status === 0) {                 msg = 'not connect.\n verify network.';             } else if (jqxhr.status == 404) {                 msg = 'requested page not found. [404]';             } else if (jqxhr.status == 500) {                 msg = 'internal server error [500].';             } else if (exception === 'parsererror') {                 msg = 'requested json parse failed.';             } else if (exception === 'timeout') {                 msg = 'time out error.';             } else if (exception === 'abort') {                 msg = 'ajax request aborted.';             } else {                 msg = 'uncaught error.\n' + jqxhr.responsetext;             }             alert(msg);         }     }); 

do need use different url? or there other setting required? please help.

that's right url, long replace mybucket actual bucket name. after reading through jquery.ajax(), emulated think behavior adding &callback=foo, due datatype: 'jsonp' , &_=1474410231688 because cache: false, , issued request via curl , produced valid object valid callback. can log entire jqxhr see more of status?
