Javascript Typedef Error when using parameters

What am I doing wrong, and how can one pass variables to a different function within the same wrapping variable/function.
Example:
function customFunctionWrap(){
this.myVar1 = 0;
this.getCurrentPosition = function(){
if (navigation.geolocation) {
navigator.geolocation.getCurrentPosition(function(position){});
}
},
this.doSomething = function(){ // Works
//Do something, return
this.callWithParams(); //Works
},
//If I remove passing in 'value1',calling it elsewhere works
this.doSomethingWithParams = function(value1){
//Use value1
//Return
},
this.callWithParams = function(){
var value1 = 'xyz'; //Is a variable that changes based on some DOM element values and is a dynamic DOM element
this.doSomethingWithParams(value1); //THROWS TYPEDEF ERROR: this.doSomethingWithParams is not a function
this.getCurrentPosition();
}
};
var local = new customFunctionWrap();
local.doSomething(); //WORKS
I know there is another way to do it and then directly use customFunctionWrap.callWithParams(), but am trying to understand why the former approach is erroring out.
var customFunctionWrap = {
myVar1 : 0,
callWithParams : function(){
}
}

What JS sees:
var customFunctionWrap = (some function)()
returned function is fired, because the last (), so it has to yield/return something, otherwise, like in your code it is "returning" undefined.
So your given code does not work.
The very first fix is to delete last 2 characters from
var customFunctionWrap = (some function)()
to make it return constructor.

How to declare instance of a class within a instance of class?

I am making a simple hmtl/js game. I'd like to have all the data of the Game in DataofGame. It is like tennis, it is simpler than tennis: there is only set and match. changeinSet is called on click.
But I think i have a problem with private variable so it doesn't work.
Uncaught TypeError: Cannot read property 'WordsoftheGame' of undefined
//Added
document.getElementById('playboutton').addEventListener('click', newGame);
function newGame() {
var DataofGame = new newGameData();
}
// New game
function newGameData() {
this.pointTeam1 = 0;
this.pointTeam2 = 0;
this.WordsoftheGame = ShuffleListe();
this.ASet = new aSet();
}
//How the set is manage ********************
function aSet() {
var oneWord = DataofGame.ListeMot;
// display the word and delete it from the list
document.getElementById('jouer').innerHTML = oneWord[0];
DataofGame.WordsoftheGame.shift();
this.turn = true;
this.score = 0;
}
function changeinSet() {
DataofGame.ASet.score += 1;
//This is the other team's turn:
DataofGame.ASet.turn = !DataofGame.ASet.turn;
};
//shuffle liste
ListOfWords = ['Artiste', 'Appeler', 'Cheval', 'Choisir', 'Ciel', 'Croire', 'Dormir'];
function ShuffleListe() {
data = shuffle(ListOfWords);
return data;
}

function newGameData(){
this.pointTeam1=0;
this.pointTeam2=0;
this.WordsoftheGame= ShuffleListe();
this.ASet=new aSet();
}
//How the set is manage ********************
function aSet(){
var oneWord=DataofGame.ListeMot;
// display the word and delete it from the list
document.getElementById('jouer').innerHTML=oneWord[0];
DataofGame.WordsoftheGame.shift(); // << DataofGame not assigned yet
this.turn=true;
this.score=0;
}
Here when you're accessing DataofGame, it's not yet assigned because you're inside the constructor when calling aSet().
What you want to achieve is not completely clear, but if it's adding an ASet method to your object, you could write something like this:
function newGameData(){
this.pointTeam1=0;
this.pointTeam2=0;
this.WordsoftheGame= ShuffleListe();
this.ASet = function() {
// your code
};
}
NB your coding style for names is a bit messy, you should use uppercases consistently. The usage is to start constructor names with uppercases, the rest in lower cases.

You can let the function return an object with the data or just set the object.
function newGameData(){
return {
pointTeam1 : 0,
pointTeam2 : 0,
WordsoftheGame : ShuffleListe(),
ASet : new aSet()
}
}
But I would recommend to search for how to work with objects in javascript. Maybe this helps:

return a object with parameter

I've an object called 'sheet1'
var nr = 1;
function Sheet(title){
this.div = document.createElement('div');
this.div.dataset.sheetNr = nr;
this.div.dataset.sheetTitle = title;
document.getElementById("sheets").appendChild(this.div);
nr++;
}
Sheet.prototype = {
constructor: Sheet,
get : function(data){
return this.div.dataset.data;
}
}
var sheet1 = new Sheet("Title1");
now when I call the function
sheet1.get("sheetNr");
it returns 'undefined' !...how can I solve this problem?
// console.log(data); outputs sheetNr
but when I change my function like
Sheet.prototype = {
constructor: Sheet,
get : function(){
return this.div.dataset.sheetNr;
}
}
and then call
sheet1.get();
it returns the number of the sheet...1 in this case...

You don't have a data attribute defined on the div you are creating sot it doesn't exist as called. When you call this.div.dataset.sheetNr you are actually hitting a defined attribute. To use the variable data as an index you need to call:
this.div.dataset[data] instead.

Javascript custom eventlistener not working?

These are the sections of code from my custom event listeners that is not working.
Why does this return '-1' var idx=functionList[eventType].indexOf(callback) when they are the same?
When I use the following in the myObject.removeCustomEventListenr() method
console.log(functionList[eventType][0]) /*the console shows
function(){console.log('firedEvent')*/
console.log(callback) /*the console shows
function(){console.log('firedEvent')*/
both the same thing so why does it not work
Below is the full part that is causing trouble
var myObject = {}
var functionList = {}
myObject.addCustomEventListener = function(eventType,callback){
if(!functionList[eventType]){
functionList[eventType] = []
}
functionList[eventType].push(callback)
//creates functionList.start[0] = function(){console.log('firedEvent')}
}
myObject.removeCustomEventListener = function(eventType,callback){
if(functionList[eventType]){
var idx = functionList[eventType].indexOf(callback)
console.log(idx) //logs '-1' should however match and return 0
if(idx!=-1){
functionList[eventType].splice(idx,1)
console.log('removed')//obviously does not remove the function form the array
}
}
}
myObject.addCustomEventListener('start',function(){console.log('firedEvent')})
myObject.removeCustomEventListener('start',function(){console.log('firedEvent')})
Please explain why this occurs and how I can fix it?
Thanks

The problem is that you're passing references to 2 different functions to the add and remove functions, here:
myObject.addCustomEventListener('start',function(){console.log('firedEvent')})
myObject.removeCustomEventListener('start',function(){console.log('firedEvent')})
While the code in the functions is the same, they're both separate objects as far as JavaScript is concerned, meaning you can't find one when passing the other to indexOf()
This should work:
var callback = function(){
console.log('firedEvent')
};
myObject.addCustomEventListener('start', callback)
myObject.removeCustomEventListener('start', callback)
var myObject = {}
var functionList = {}
myObject.addCustomEventListener = function(eventType,callback){
if(!functionList[eventType]){
functionList[eventType] = []
}
functionList[eventType].push(callback)
//creates functionList.start[0] = function(){console.log('firedEvent')}
}
myObject.removeCustomEventListener = function(eventType,callback){
if(functionList[eventType]){
var idx = functionList[eventType].indexOf(callback)
console.log(idx) //logs '-1' should however match and return 0
if(idx!=-1){
functionList[eventType].splice(idx,1)
alert('removed')//obviously does not remove the function form the array
}
}
}
var callback = function(){
console.log('firedEvent')
};
myObject.addCustomEventListener('start', callback);
myObject.removeCustomEventListener('start', callback);

unable to change javascript object property with async, nodejs and mongodb

I have the following code:
exports.home = function(Comment,User,Activity){
return function(req, res){
var get_url = req.url.split(/\?/)[1];
if (!req.user)
{
res.writeHead(302, {
'Location': '/'
});
res.end();
return;
}
var posts_id_array = req.user.posts_id_array;
var stocks_array = req.user.watch_list;
var subscribe_to_arr = req.user.subscribe_to;
User.find({_id:{$ne:req.user._id, $nin:subscribe_to_arr}}).sort('-_id').limit(10).exec(function(err_user, users){
Activity.find({$or:[{owner_id : {$in :subscribe_to_arr}},{owner_id:req.user._id}]}).sort('-time_stamp').limit(20).exec(function(err_post,activities){
if( err_post || !activities) {
res.render('home',{user:req.user,stocks:JSON.stringify(stocks_array)});
}
else
{
var funcArr = [];
var hasPost = ["publish","comment","like"];
var notPost = ["add_stock","delete_stock"];
for(var i =0;i<activities.length;i++)
{
if(hasPost.indexOf(activities[i].type)!=-1){
var fobj = {
act: activities[i],
f:function(callback){
var test = this.act;
var comments = test.post.comments;
Comment.find({_id:{$in:comments}},function(err,_comments){
console.log("test.post.comments");
//console.log(test.post.comments);
console.log("comments ");
console.log(_comments);
console.log("type");
console.log(typeof test);
console.log("cloning obj");
// obj = JSON.parse(JSON.stringify(test)); // cloning obj
console.log(test);
console.log("setting value of comments");
**console.log(test.post.comments = _comments);** //unable to change test.post.comments
console.log("after assignment");
console.log(test.post.comments); // remain unchanged but work with obj.post.comments if I clone test as obj and use obj instead.
callback(null,test);
});
}
}
funcArr.push(fobj.f.bind(fobj));
}else{
var fobj = {
act: activities[i],
f :function(callback){
callback(null,this.act);
}
}
funcArr.push(fobj.f.bind(fobj));
}
}
async.series(funcArr,function(err,resArr){
console.log("resArr");
console.log(resArr);
res.render('home',{user:req.user,posts:JSON.stringify(resArr),stocks:JSON.stringify(stocks_array), other_users:JSON.stringify(users)});
});
}
});
}) // end of User.find
}// end of return function(req,res);
}
I want to update the post.comments property of the "test" object (see ** parts), but I was unable to do so. However, when I cloned the "test" object as "obj" then set "obj.post.comments" it works. Why is it the case? Is it because I messed up some scoping issues?
Thanks.

I have solved this problem myself. It turns out that I have store mongodb's Schema.Types.ObjectId in the test.post.comments which after some messing around I found cannot be overwritten. When I create a clone of the test object as "obj", the Schema.Types.ObjectId object in obj.post.comments is stored at a different location which allows for modification. My conjecture is that test.post.comments points to a Schema.Types.ObjectId within mongodb itself and therefore cannot be overwritten. When I create a copy of the test object, the problem is therefore resolved.

var test = this.act.concat();
use this instead.
because arrays substitution in js actually does not copy array but refer original adresses.
for example
var test = ['A','B','C','D'];
var copied = test;
test[0] = 0;
copied[1] = 0;
console.log(test) //0,0,'C','D'
console.log(copied) //0,0,'C','D'
so to avoid this issue, You can use .concat() to copy array
if you do not add anything, it will be used as copying.
var test = ['A','B','C','D'];
var copied = test.concat();
test[0] = 0;
copied[1] = 0;
console.log(test) //0,'B','C','D'
console.log(copied) //'A',0,'C','D'
