javascript - Google Sign-in: how to avoid popup dialog if user is already signed in by using listeners? -


right i'm using auth2.attachclickhandler(element, {}, onsuccess, onerror);. works, if i've signed in, dialog box opens , closes right away rather ugly. there way around using listeners?

i played around example i'm not sure if listening changes current user need, , check of googleuser seems risky.

auth2 = gapi.auth2.init({client_id: 'xxxxx'}); auth2.currentuser.listen(function (user) {       googleuser = user;       if (typeof(googleuser.getbasicprofile()) !== 'undefined')         document.getelementbyid('signupasgoogle').addeventhandler('click', popuplateform);       else         auth2.attachclickhandler(document.getelementbyid('signupasgoogle'), {}, onsuccess, onerror);

is there better way? thanks

here did solve same problem!

auth2 = gapi.auth2.init({     clientid: '${clientid}',     cookiepolicy: '${cookie_policy}', });  auth2.currentuser.listen(function (googleuser) {     if (googleuser.issignedin()) {         // login(googleuser) function     } else {         auth2.attachclickhandler("your button", {},             function (googleuser) {                 // login(googleuser) function             }, function (error) {             });     } });

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
