Javascritp app.js function returning Undefined

Question

I'm trying to write a simple function retrieving the contract address with a simple call. Anyway while the address value is correct in the function scope, the return value calling the function in that way is giving me an undefined error.

//Here the call

console.log("Indirizo con chiamata",App.getContractAddress());


//Here the function code


getContractAddress: function() {

RevenueShare.setProvider(web3.currentProvider);
  myContractInstance=RevenueShare.deployed();

myContractInstance.then(function(instance){
    return instance.address;
}).then(function(address){
  console.log("Indirizzo in funzione:",address);
  return address;
});
},

Any Help???

Answer 1

I think it is just a javascript problem. try this fix :

Function

getContractAddress: function() {
 return new Promise((res,rej)=>{
RevenueShare.setProvider(web3.currentProvider);
  myContractInstance=RevenueShare.deployed();

myContractInstance.then(function(instance){
    return instance.address;
}).then(function(address){
  console.log("Indirizzo in funzione:",address);
  res(address);
});

})

}

Function Call

App.getContractAddress()
.then(
    data=>{
        console.log("Indirizo con chiamata",data);
    })
