Calling another function after value is not working

I have a simple code to call a value from another function and its not working :
function ABC() {
var ID = XYZ(id);
Logger.log(ID); //throws error not defined.
}
function XYZ(id) {
var id = "1234"
return id;
}
What I wan to do is capture the value of id from function XYZ and Logger.log it into function ABC. But this reflects error.

Still not sure what you are trying to do with your code. This code is an "Impure Function" which is not recommended in JavaScript. How much I understood your code, below are my suggestions:
First
function abc() {
var id = xyz();
Logger.log(id);
}
function xyz() {
// Add whatever logic you want here to return ID value
var id = "1234"
return id;
}
Second
function abc() {
// Pass any value as an argument based on your requirement
var results = xyz('', '', '');
Logger.log(results.id);
Logger.log(results.name);
Logger.log(results.number);
}
function xyz(id, name, number) {
// Add whatever logic you want here
var newId = id || "1234";
var newName = name || "Mask";
var newNumber = number || "1234567890";
return { id: newId, name: newName, number: newNumber };
}
Based on what suits your requirement, you can take help of these codes.

Here you go -
function ABC() {
var ID = XYZ();
Logger.log(ID); // No longer throws the error :)
}
function XYZ() {
var id = "1234"
return id;
}

You do not need two functions, here is a simple function that will return the ID passed in.
const ABC = (id) => {
return id;
}
let a = ABC(122443);
console.log(a) // output 122443

Passing variable into object method javascript

trying to get my head around objects, methods, closures, etc... in Javascript.
Can't see why this isn't working, some fundamental flaw in my thinking I guess. I'm expecting the val variable to be passed through to the addNote() function but it isn't. I thought that any variables declared outside of a function are available to that function, as long as they're not within another function. Is that not correct?
if(typeof(Storage) !== "undefined") {
console.log(localStorage);
var $input = $('#input'),
$submit = $('#submit'),
$list = $('#list'),
val = $input.val();
var noteApp = {
addNote : function(val) {
var item = val.wrap('<li />');
item.appendTo($list);
clearField();
},
clearField : function() {
$input.val = '';
},
delNote : function(note) {
}
};
$submit.on('click', function(){
noteApp.addNote();
});
} else {
}
I'm trying to learn how the pros manage to get their code so clean, concise and modular. I figured a note app would be a perfect start, shame I got stuck at the first hurdle...
Cheers.

There are several issues with the code in the question
defining an argument named val and not passing an argument to the function
when calling clearField() inside the object literal it's this.clearField()
You're only getting the value once, not on every click
val is a string, it has no wrap method
$input.val = ''; is not valid jQuery
I would clean it up like this
var noteApp = {
init: function() {
if (this.hasStorage) {
this.elements().events();
}
},
elements: function() {
this.input = $('#input');
this.submit = $('#submit');
this.list = $('#list');
return this;
},
events: function() {
var self = this;
this.submit.on('click', function(){
self.addNote();
});
},
hasStorage: (function() {
return typeof(Storage) !== "undefined";
})(),
addNote: function() {
this.list.append('<li>' + this.input.val() + '</li>');
this.clearField();
return this;
},
clearField: function() {
this.input.val('');
},
delNote : function(note) {
}
}
FIDDLE
Remember to call the init method
$(function() { noteApp.init(); });

In your call to addNote(), you don't pass any argument for the val, so it will be undefined:
noteApp.addNote();
// ^^ nothing
Pass the input (seems you want the jQuery object not the string value because of your val.wrap call):
noteApp.addNote($input);
When you declare the val in the function, it is scoped to that function and will only be populated if the function call passes a value for that argument. Even if you have another variable in an upper scope with the same name val, they are still differentiated. Any reference to val in the function will refer to the local val not the upper scope.

knockout pass additional parameters to subscription function

What I want to achieve is to create subscription for model properties. This subscription function should call WebApi via Ajax updating property value in database. For ajax call I need three paramaters: "fieldName", "fieldValue" and "modelId", ajax will update database row based on those three parameters.
I have many properties and all of them need the same functionality, so I do not want to subscribe for each property individually, so I found a following suggestion:
ko.subscribable.fn.withUpdater = function (handler) {
var self = this;
this.subscribe(handler);
//support chaining
return this;
};
Add this is how it is "attached" to observables:
self.ModelId= ko.observable();
self.CompanyName = ko.observable().withUpdater(update);
where update is some js function outside model.
However, I have problem, because I am not able to pass three paramaters to update functions (or also I can say in another words - I need to be able to get viewModel.ModelId property value inside update, as well as propertyName).
function update (propertyName, propertyNewValue, anotherPropertyValue) {
//do ajax update
}
As an example for CompanyName property it will be:
update("CompanyName", "New Company value here", 3),
where
3 == viewModel.ModelId

There might be a better way to do this, but the following will work:
First, add a target object to the withUpdate method:
ko.subscribable.fn.withUpdater = function (handler, target, propname) {
var self = this;
var _oldValue;
this.subscribe(function (oldValue) {
_oldValue = oldValue;
}, null, 'beforeChange');
this.subscribe(function (newValue) {
handler.call(target, _oldValue, newValue, propname);
});
return this;
};
The update subscribe function will get scoped to the target property:
var update = function (propertyName) {
console.log('propname is '+ propname + ' old val: ' + oldvalue + ', new val: ' + newvalue + ', model id: ' + this.ModelId());
}
Now you will need to use it a little differently.
self.CompanyName = ko.observable().withUpdater(update, self, "CompanyName");
An example http://plnkr.co/edit/HhbKEm?p=preview
I couldn't get the scope of the withUpdater function to be that of the object without explicitly passing in the target and a string for the company name.

You can declare your function as a variable outside of the 'fn' scope.
var dataservice = 'my class that has the data calls';
var altFunc = function () {
return ko.pureComputed(function () {
var currentItem = this().filter(function (item) {
// Do knockout stuff here and return your data
// also make calls to the dataservice class
}, this, dataservice);
};
ko.observableArray.fn.someNewFunctionality = altFunc;

could not get the property value of my object in angularJs

I get undefined whenever I get the value of a property of an object.
function run(id){
var report = services.getReportInfo(id);
var childReport = {
id: newGuid(),
parentId: report.id, // i get undefined
reportPath: report.path // i get undefined
};
...
}
services.js
angular.module('project.services').factory('services', function(){
var reports = [
{
....
},
{
....
}
];
function getReportInfo(id){
var report = reports.filter(function(element){
return element.id === id;
});
};
return{
getReportInfo: getReportInfo
};
}
Whenever I put breakpoint on my var report = services.getReportInfo(id) it could contains the correct values for each property of the my report object. However, when I get the report.id or report.path, I get undefined value.
--Edited--
Oh, I know now where I got wrong.
The getReportInfo function returns an array and I'm accessing the properties without telling from what index should it get the values for the said properties.
function run(id){
var report = services.getReportInfo(id);
var childReport = {
id: newGuid(),
parentId: report[0].id,
reportPath: report[0].path
};
...
}
I placed static index 0, since I know that the array will always have a length of 1.

You are not returning anything from the .factory method and the getReportInfo is also not returning anything. For what you are trying to do, try to use .service method:
angular.module('project.services').service('services', function(){
var reports = [
{
....
},
{
....
}
];
this.getReportInfo = function (id){
var report = reports.filter(function(element){
return element.id === id;
});
return report;
}
}
Here is a good explanation on how to use .factory and .service:
Confused about Service vs Factory

Two immediate issues with the code I can see:
1) Your factory function needs to return a value or constructor function. Right now your code is not initializing the factory to any value.
2) Your getReportInfo function also doesn't return a value, yet you are assigning the function result to a variable.

Set Method doesn't set the Member though being called with valid argument

im getting frustrated because of this piece of code:
function Model(){
this.GetAjaxData = function(){
//private Member to be returned
var res;
function setRes(newVal){
res = newVal;
alert(newVal); // to verify its really being called
}
// calls a Ajax-Service(1st param) with the given arguments(2nd param),
// the 3rd param is a function with gets called back, commiting the
// output of the Ajax-Service as arguments for the called function
tw.coach.callService(
"GetServerTime",
"<inputs><variable name='input1' type='String'>lala</variable></inputs>",
function(arg){ setRes(arg['Result']); }
);
return res;
};
}
Now, what happens is, once an instance of model has been initialized and the method is being called like:
var _model = new Model();
document.getElementById("myDiv").innerHTML = _model.GetAjaxData();
the alert pops up with the expected data (the Ajax Service simply returns {Result: this came via Ajax.}) but myDiv constains undefined. This tells me that the setRes() is called correctly but it just doesn't set the value of res.
And I have no idea why.

Change your approach taking into consideration async nature of AJAX requests:
function Model() {
this.GetAjaxData = function(callback) {
var data = "<inputs><variable name='input1' type='String'>lala</variable></inputs>";
tw.coach.callService("GetServerTime", data, function(arg) {
callback(arg['Result']);
});
};
}​
var _model = new Model();
_model.GetAjaxData(function(res) {
document.getElementById("myDiv").innerHTML = res;
});
