Tag: returns

I am looking for callbacks and asynchronously in Javascript.

The HelloWorld.prototype.getCont function searches the ID of an account and returns a number. EX: 1;
The HelloWorld.prototype.getAllAccounts function should retrieve the number of the result, e.g. B.: (1) and retrieve all account information. However, it executes the HelloWorld.prototype.getCont function, but does not save a result.
someone, please give the light: D

what does he not store data in variable?

var IDMembro = this.getCont (); // DISPLAY DATA AGAIN

with what the code around but no save return? Thank you very much

HelloWorld.prototype.getCont = function(cb) { //GetCont é um objeto Função
 var MyAddress = window.web3.eth.accounts(0);
 document.getElementById("Address").innerHTML =  MyAddress ;
         this.instance.AccountAddress(MyAddress, function (error, result) {      
  document.getElementById("IDAccount").innerHTML =  result ;
 console.log (result); //DATA OK
 return result; 
});  
}


HelloWorld.prototype.getAllAccounts = function(cb) {
       var IDMembro =  this.getCont(); //SHOW DATA AGAIN
 console.log (IDMembro); //VALUE INDEFINED??

          this.instance.AllAccounts(1, function (error, result) {      
 document.getElementById("AllAccounts0").innerHTML =  result(0);
  document.getElementById("AllAccounts1").innerHTML =  result(1);
   document.getElementById("AllAccounts2").innerHTML =  result(2);
    document.getElementById("AllAccounts3").innerHTML =  result(3);
     document.getElementById("AllAccounts4").innerHTML =  result(4);
      document.getElementById("AllAccounts5").innerHTML =  result(5); 

  });

}
