making JSON from string

I have a job to refractor strings to start using json so they can just pass json objects. So I have made array of names and then I'm trying to go through and make key and values but I'm getting an error in the console that it cant find x of no value. Can someone point me in the right direction?
var newName = ['ManagingOrg', 'ActiveOrg', 'Severity', 'SeverityClassification', 'WorkQueue', 'TicketState',................ to long to post];
$().each(newName, function (key, value) {
key = newName[this];
value = newValues[this] = $('#' + key).val();
newArray = [key][value];
newArray = JSON.stringify(newArray);
alert(newArray);
$('.results').html(origArray[TicketNumber]);
});

I'm assuming you have "newValues" and "origArray" defined elsewhere?
In any case you'll need to at least adjust the following:
"$().each" should be $.each
"newArray" should be defined outside and you should use newArray[key] = value
you don't have a variable "TicketNumber" defined and so you should wrap "TicketNumber" in quotes
this is a reserved word so you shouldn't use it in "newName[this]" or "newValues[this]"
I suggest using a for loop instead of $.each() based on what you're trying to do inside.

var origArray = [];
var newName = ['ManagingOrg', 'ActiveOrg', 'Severity', 'SeverityClassification'
];
for (var i = 0; i < newName.length - 1; i++) {
var object = {};
object[newName[i]] = newName[i];
object = JSON.stringify(object);
origArray.push(object);
}

Javascript create object with property as dynamic objects

I tried a lot searching and didnt get desired solutions.
What I want to achieve is
var myObject {
id1 : {
name:place_name,
location : place_loc
},
id2 : {
name:place_name,
location : place_loc
},
id3 : {
name:place_name,
location : place_loc
}
}
What I want to do is that Initially I want the properties "id1", "id2".. to be dynamic. And then dynamically assign name:place_name and other properties of each property.
I dont know the number of properties (id1,id2,id3...) hence would like to add them dynamically and following the addition of properties(id1,id2... ) I want to dynamically add the property values. (place_name & place_loc) of each id.
My code looks something like this.
var myObject = {};
myObject[idnumber1].place = "SomePlace1";
myObject[idnumber1].place = "SomeLoc1";
myObject[idnumber2].place = "SomePlace1";
myObject[idnumber2].place = "SomeLoc1";
But it gives error.
I know it seems simple doubt but any help would be grateful.
Thanks in advance. :)

You are trying to set a value of already assigned objects at keys "idnumber1", etc.
What you'll need is to initialize each objects for your ids like this:
var myObject = {};
myObject[idnumber1] = {};
myObject[idnumber1].place = "SomePlace1";
myObject[idnumber2] = {};
myObject[idnumber2].place = "SomeLoc1"

I would do it this way, it's not exactly what you did ask for, but I think it will become easier to change this later on.
function Place(name, location) {
this.name = name;
this.location = location;
}
var myObject = {}
myObject['id1'] = new Place('Foo', 'Bar');
myObject['id2'] = new Place('Internet', 'test');
console.log(myObject);

To dynamically create objects in your collection, you can use a numerical counter variable to create your object collection (myObject["id" + i] = {name: place_name, location: place_loc}).
An example:
var myObject = {};
for (i = 0; i < 20; i++){
myObject["id" + i] = {name: place_name, location: place_loc}
}
In practice, you can use a counter that you increment outside of a loop.

In JS,how to get a obj variable's name

like this code
var Obj = function () {}
Obj.prototype.getVarName = function () {
console.log( someFunction() );
}
var obj = new Obj();
obj.getVarName(); //output "obj";
var obj1 = new Obj();
obj1.getVarName(); //output "obj1";
and i don't want to do it in this way
var Obj = function (variableName) {
this.variableName = variableName || "undefined";
}
Obj.prototype.getVarName = function () {
console.log(this.variableName);
}
var obj = new Obj('obj');
obj.getVarName(); //output "obj";
var obj1 = new Obj('obj1');
obj1.getVarName(); //output "obj1";
someone has any idea to do with this problem,thanks.
p.s：I was doing something in somg incorrect way.so I ask this Unanswered question,thanks all guys.
I bing an event to an DOM elem by a class obj's method ,and this obj has somg child class obj,when trigger the event,this varialbe is point to the dom elem,any I don't know how to recognition which obj trigger this event,so i try this way.
But it's a wrong way!So i try it by some other method.I use the call method to change the this variable,and now i solve my problem.

I believe the answer is "it can't be done".
Variable labels aren't meant to be looked at by your code at run-time. They're meant for you, as the program author, to be used at program write-time.
If an Object needs a label that you need to examine and use at run-time you should give it that property to use.
someObject.myName = "someObject"; // if that's what you really want

There's simply no relation from an object to the variable holding it as value.
Because there can be more than one variable.
var obj = new Obj();
var obj2 = obj;
obj2.getVarName(); // what do you want ?
That's one of the basis of the concept of variable in probably all programming languages. You won't change that. if you want your objects to have a name, the solution is to give them a name, not using the variable names.

What dystroy and Genia S. said.
Your code smells BAD. Why are you trying to do this?
The way you don't want to do it actually looks like the best option, i.e. create an object with a name field.

Setting dynamically an Object in JavaScript

It seems complicated for me.
First, I have this list:
liste_path_categories.push(
{ index: null
, letter: "letter1"
, type: key
, picture_url: "url1"
, id_categ: null
, response: "Answer here"
});
What I want is to extract from this big list an object in this form:
data["String1"]["String2"]= String3
With :
String1=list_path_categories[i].letter
String2=list_path_categories[i].id_categ
String3=list_path_categories[i].response
example:
data['A']['12'] : "A_answer"
To declare the data i make this:
var data = new Object(new Object);
How I can set all the values in data?

You can use the Array.forEach method to iterate through liste_path_categories and construct your data object.
Example:
var liste_path_categories = [];
var data = {};
liste_path_categories.push(...);
...
liste_path_categories.push(...);
liste_path_categories.forEach(function(element) {
data[element.letter] = {};
data[element.letter][element.id_categ] = element.response;
});
jsFiddle example : http://jsfiddle.net/3ZvNf/

Your question is pretty vague but do you mean something like this?
Setting a dynamic property in an object wich belongs to another object?
data['A']['12'].answer = "A_answer"

Instead of using strings, you have to use the variables in your property access:
var data = {};
if (!data[String1]) {
data[String1] = {}; // make sure that data[String1] exists and is an object
}
data[String1][String2] = String3;
If you want to do this for elements in the array, you have to iterate over the array.
P.S.: I recommend to use more expressive variable names than StringX.

first create the constructor (in OOP terminology):
var ctor_object = function(letter,id_categ,response)
{
this.letter = letter;
this.id_cated = id_categ;
this.response = response;
}
(in genereal you should omit the ctor_ syntax and name it directly after the name of the class of your object)
then use your constructor upon your list of categories:
var length = liste_path_categories.length,
element = null;
for (var i = 0; i < length; i++)
{
element = liste_path_categories[i];
my_obj = new ctor_object(element.letter,element.id_categ,element.reponse)
// Do something with my_obj
}

Get variable names with JavaScript

I want to create a log function where I can insert variable names like this:
var a = '123',
b = 'abc';
log([a, b]);
And the result should look like this in the console.log
a: 123
b: abc
Get the value of the variable is no problems but how do I get the variable names? The function should be generic so I can't always assume that the scope is window.

so the argument is an array of variables? then no, there is no way to get the original variable name once it is passed that way. in the receiving end, they just look like:
["123","abc"];
and nothing more
you could provide the function the names of the variables and the scope they are in, like:
function log(arr,scope){
for(var i=0;i<arr.length;i++){
console.log(arr[i]+':'scope[arr[i]]);
}
}
however, this runs into the problem if you can give the scope also. there are a lot of issues of what this is in certain areas of code:
for nonstrict functions, this is window
for strict functions, this is undefined
for constructor functions, this is the constructed object
within an object literal, this is the immediate enclosing object
so you can't rely on passing this as a scope. unless you can provide the scope, this is another dead end.
if you pass them as an object, then you can iterate through the object and its "keys" and not the original variable names. however, this is more damage than cure in this case.

I know you want to save some keystrokes. Me too. However, I usually log the variable name and values much like others here have already suggested.
console.log({a:a, b:b});
If you really prefer the format that you already illustrated, then you can do it like this:
function log(o) {
var key;
for (key in o) {
console.log(key + ":", o[key]);
}
}
var a = '1243';
var b = 'qwre';
log({
a:a,
b:b
});
Either way, you'd need to include the variable name in your logging request if you want to see it. Like Gareth said, seeing the variable names from inside the called function is not an option.

Something like this would do what you're looking for:
function log(logDict) {
for (var item in logDict) {
console.log(item + ": " + logDict[item]);
}
}
function logSomeStuff() {
var dict = {};
dict.a = "123";
dict.b = "abc";
log(dict);
}
logSomeStuff();

Don't know if this would really work in JS... but you can use a Object, in which you can store the name and the value:
function MyLogObject(name, value) {
this.name = name;
this.value = value;
}
var log = [];
log.push(new MyLogObject('a', '123'));
log.push(new MyLogObject('b', 'abc'));
for each (var item in log) {
if (item.value != undefined)
alert(item.name + "/" + item.value);
}
Then you can loop thru this Object and you can get the name and the value

You can't access the variable names using an Array. What you could do is use objects or pass the variable names as a String:
var x = 7;
var y = 8;
function logVars(arr){
for(var i = 0; i < arr.length; i++){
alert(arr[i] + " = " + window[arr[i]]);
}
}
logVars(["x","y"]);

I had a somewhat similar problem, but for different reasons.
The best solution I could find was:
MyArray = ["zero","one","two","three","four","five"];
MyArray.name="MyArray";
So if:
x=MyArray.name;
Then:
X=="MyArray"
Like I said, it suited my needs, but not sure HOW this will work for you.
I feel silly that I even needed it, but I did.

test this.
var variableA="valor01"; <br>
var variableB="valor02";
var NamevariableA=eval('("variableA")');<br>
var NamevariableB=eval('("variableB")');<br>
console.log(NamevariableA,NamevariableB);
atte.
