javascript - Firebase: Get userdata obj and bring back the user profile without page refresh? -


it's been 2 days i'm trying achieve need refresh page if want user profile db. there way without page refresh? need use sort of jquery ajax achieve it? possible?

here 2 method, they're working need page refresh before bring user profile.

 function authdatacallback(authdata) {   if (authdata) {     var fb = new firebase('https://blistering-torch-8000.firebaseio.com/users/public/');     fb.child(authdata.uid).on('value', function(data) {       var mydata = data.val();       var datestring = mydata.date.split(' ').slice(0, 4).join(' ');       $('.profile').append('<li>username: ' + mydata.username + '</li>');       $('.profile').append('<li>joined: ' + datestring + '</li>');     });     var fb = new firebase('https://blistering-torch-8000.firebaseio.com/users/private/');     fb.child(authdata.uid).on('value', function(data) {       var mydata = data.val();       $('.profile').append('<li>email: ' + mydata.email + '</li>');     });   } else {     console.log('profile: no data, no 1 logged in');   } } fb.onauth(authdatacallback);

or 

var fb = new firebase('https://blistering-torch-8000.firebaseio.com/'); var getauth = fb.getauth();  function getprofile(authdata) {   if (authdata) {     var fb = new firebase('https://blistering-torch-8000.firebaseio.com/users/public/');     fb.child(authdata.uid).on('value', function(data) {       var mydata = data.val();       var datestring = mydata.date.split(' ').slice(0, 4).join(' ');       $('.profile').append('<li>username: ' + mydata.username + '</li>');       $('.profile').append('<li>joined: ' + datestring + '</li>');     });     var fb = new firebase('https://blistering-torch-8000.firebaseio.com/users/private/');     fb.child(authdata.uid).on('value', function(data) {       var mydata = data.val();       $('.profile').append('<li>email: ' + mydata.email + '</li>');     });   } else {     console.log('profile: no data, no 1 logged in');   } } getprofile(getauth);

db rules:

{   "rules":    {     "users":      {       "public":        {          // allow me list users name         ".read": true ,         ".write": true       },        "private":        {         "$uid":          {           // readable owner           ".read": "auth.uid === $uid",           ".write": true         }       }     }      } }

both onauth , getauth return null when not authenticated. fix login/function call sequence.

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
