@rsharma

Did you mean creating QML objects dynamically? Take a look at this, https://doc.qt.io/qt-5/qtqml-javascript-dynamicobjectcreation.html

hi @SeanKim

when i check for newtworkrequest done, it always give me the error

if (newObj.readyState === NetworkRequest.DONE){ console.log("done") }

ReferenceError: NetworkRequest is not defined

so i tried like this way

if(newObj.readyState===4){ console.log("done"); DB.insertMediaDetails(dev_href_fname,ref_no,ref_type); console.log("done inserting"); return dev_href_fname; }

calling fnc DB.insertMediaDetails(dev_href_fname,ref_no,ref_type);

but it always return fron this cond before readystate become 4 and return undefined
