I'm new to node and javascript and have been banging my head on the following. I've created an object as follows:
var Subscriber = {
'userID': String,
'email': String,
'name': String,
'stage': String,
'poster': Boolean,
'canEmail': Boolean,
'stage': String, }
I have a function where I query mongodb, and loop through the results, attempting to load an array of subscribers, which I've declared as:
var s = Subscriber;
var subscribers = [];
The loop looks like this:
//load array of users that are subscribed to the group
async.forEach(g.subscribers, function(item, callback) {
//load user document for this user
User.findOne({ _id: item}, function(err, u) {
if(!err && u) {
//var s = new Subscriber();
console.log('Sub load, found user %s, building array item', u.email);
console.log('Subs @ loop start');
console.log(util.inspect(subscribers));
console.log('Heres foo: ' + util.inspect(foo));
s.userID = u._id;
s.email = u.email;
s.name = u.firstName + ' ' + u.lastName;
s.stage = u.stage;
s.poster = false; //we're just loading subscribers at this point'
if(s.stage != 'new') s.canEmail = true;
//push new subscriber onto the array
console.log('Pushing ' + util.inspect(s));
subscribers.push(s);
console.log('At end ' + util.inspect(subscribers));
foo.push(s.email);
console.log('Heres foo now: ' + util.inspect(foo));
callback(null, item);
}
After each call to subscribers.push(s), the array has the correct number of elements, but all elements match the last values for s, like this (with two different users being pulled from the DB):
[ { userID: 4fc53a71163006ed0f000002,
email: 'test@test.com',
name: 'undefined undefined',
stage: 'new',
poster: false,
canEmail: true },
{ userID: 4fc53a71163006ed0f000002,
email: 'test@test.com',
name: 'undefined undefined',
stage: 'new',
poster: false,
canEmail: true } ]
Pushing a single element of s rather than the whole object seems to be fine. I added the "foo" array as a test, and it works fine:
Heres foo now: [ 'email1@foo.com', 'test@test.com' ]
What is going on here?!?!??!
