filereader {}     error: null     onabort: null     onerror: null     onload: null     onloadend: null     onloadstart: null     onprogress: null     readystate: 2     result: "_id,number,date,duration,type,new,name,numbertype,numberlab... 

if output of reader have specified correct

reader>filereader>result result in undefined result not inside filereader
