<https://stackoverflow.com/questions/45236919/outside-for-loop-var-value-is-undefined#>
I'm facing a problem with a value where inside my for cycle it has values
like "179" and outside i get always undefined. Why?
var countRepetidos;if(obj.data.list!={} && obj.data.list.length>0){
var aux = obj.data["list"];
countRepetidos=0;
for(var i=0;i<aux.length;i++){
Database.Probing.getMacAdress(aux[i]).then(function(data){
if(data.count>0){
countRepetidos++;
console.log("count repetidos 1",countRepetidos); // value 116
}
});
}
return resolve(countRepetidos);}
console.log("count repetidos 2",countRepetidos); // value undefined
log :
3|wscontro | count repetidos 1 1163|wscontro | count repetidos 2 undefined
I try instead of use resolve, use callback but nothing... I saw other
answers in javascript but for node.js I cant resolve this problem... I saw
the link refering thus question as a duplicate but cant figure out a
solution to this case.
