javascript - Why is it always runs the callback function as TRUE? -

there function callback:

function _isbanned(iduser, idfriend, callback){ redis.sismember("user.friend_tmp:" + idfriend, iduser, function(err, friends){ console.log(friends); if(friends == 0) { homecoming callback(true); } callback(false); }); }

function call:

isbanned(data.from, data.to, function() { // body }

despite fact console.log (friends); equal 1, function executed, , transfers command // body ...

you calling callback regardless of value of if test. passing true in 1 case , false in other case, calling callback in both cases. then, within callback aren't paying attending arguments passed callback no different behavior in 2 cases.

perhaps code should this:

isbanned(data.from, data.to, function(banned) { if (banned) { // 1 action here } else { // different action here } }

javascript
