我的系统接受一系列 SoundCloud 用户 ID，通过一系列 SC.get 函数迭代它们，以获取每个用户的信息(用户 ID、用户名、关注者和流派偏好)。

//Initialize soundcloud API with client ID
SC.initialize({
client_id: "54cb0ff94ff9313ef6ca4674e9fe3026"
});
var userIds = [9110252, 55829847, 145189041, 4184647, 225458844, 22557004, 109447512];
var userids = [];
var usernames = [];
var userFollowingsE = [];
var profile =[];
var ready = 0
for(u = 0; u < userIds.length; u++){
var id = userIds[u];
getUserData(id);
function getUserData(userid){
//**************************** USER ***************************//
SC.get("/users/"+id, function(user){
userids.push(user.id);
usernames.push(user.username);
});
//********************** USER/FOLLOWINGS **********************//
SC.get('/users/'+id+'/followings',function(followings) {
var userFollowings = [];
for(i = 0; i < followings.collection.length; i++) {
userFollowings.push(followings.collection[i].username);
}
userFollowingsE.push(userFollowings);
ready++
if(ready >= userIds.length) onComplete();
});
}
}
function onComplete(){
console.log(usernames);
console.log(userIds);
console.log(userFollowingsE);
}
var users = [
{ userid: this.userids,
username: this.usernames,
genre: this.genres,
followings: this.followings,
}
]
</script>
</body>
我希望系统做的是将这些信息与对象中相应的用户相关联，例如
var users = {
user9110252: {
userid = userid,
username = username,
genrePref = genre
followings = followings
}
}//etc...
然而，从系统输出的数组每次都会改变顺序，我认为它们之间没有关联。
我不确定如何执行此操作，欢迎提出任何建议。
最佳答案
如果您希望生成的数组看起来像您所描述的那样，您应该随时构建用户对象，而不是创建多个数组然后合并它们。
这是我尝试过的，运行它，看看它是否给你预期的结果。另请注意，我没有包含流派，因为我在提供的数据中找不到它们。

// Then get its followings
SC.get('/users/'+userid+'/followings',function(followings) {
myUser.followings = followings.collection.map(function(user){
return user.username;
});
// Push that user to the user list
users.push(myUser);
// Execute the callback if all users have been fetched
if(users.length == userIds.length){ onComplete(); }
});
});
}
function onComplete(){
console.log(users);
// Just for the demo:
document.body.innerHTML = '<pre>' + JSON.stringify(users,0,2) + '</pre>';
