Javascript looping through variables

So right now this is my current code and I'm trying to figure out a way to loop through the variables I've already declared (Assuming variables 1-9 already have values). I just wanted to know whether this was possible at all?
var title;
var brief;
var hover;
var whatTitle;
var whatDesc;
var whyTitle;
var whyDesc;
var funTitle;
var funDesc;
var titles = [];
var briefs = [];
var hovers = [];
var whatTitles = [];
var whatDescs = [];
var whyTitles = [];
var whyDescs = [];
var funTitles = [];
var funDescs = [];
var obj = {'titles' : title};
if(localStorage.getItem('titles') != null) {
var tmp = JSON.parse(localStorage.getItem('titles'));
for(var i = 0;i<tmp.length;i++) {
titles.push(tmp[i]);
}
}
titles.push(obj);
localStorage.setItem("titles", JSON.stringify(titles));
Output I want if we printed out the looped code:
var obj = {'titles' : title};
if(localStorage.getItem('titles') != null) {
var tmp = JSON.parse(localStorage.getItem('titles'));
for(var i = 0;i<tmp.length;i++) {
titles.push(tmp[i]);
}
}
titles.push(obj);
localStorage.setItem("titles", JSON.stringify(titles));
var obj = {'briefs' : brief};
if(localStorage.getItem('briefs') != null) {
var tmp1 = JSON.parse(localStorage.getItem('briefs'));
for(var i = 0;i<tmp.length;i++) {
briefs.push(tmp[i]);
}
}
briefs.push(obj);
localStorage.setItem("briefs", JSON.stringify(briefs));
var obj = {'hovers' : hover};
if(localStorage.getItem('hovers') != null) {
var tmp2 = JSON.parse(localStorage.getItem('hovers'));
for(var i = 0;i<tmp.length;i++) {
hovers.push(tmp[i]);
}
}
hovers.push(obj);
localStorage.setItem("hovers", JSON.stringify(hovers));
...etc

If the code is running in a browser, then you can do something like:
for(key in window) { console.log(window[key]) } // print all variables
The variables are associated to the global namespace. That is to say the upmost "this" reference or the window object.

You're almost there with the code you have. If you look at your "desired output" examples, you'll see that the only thing that really differs between each element of your "unrolled loop" is the key for local storage ('titles', 'briefs', 'hovers').
With that in mind, you could use an Object to map the keys to the variables you have at the top level. So this:
var titles = [];
var briefs = [];
var hovers = [];
var whatTitles = [];
var whatDescs = [];
...
Becomes (UPDATE: with the initializer values preserved):
var key_to_collection = {
'titles': [title],
'briefs': [brief],
'hovers': [hovers],
'whatTitles': [whatTitles],
'whatDescs': [whatDescs],
}
Then, you loop over the values of this object:
Object.keys(key_to_collection).forEach(function(key) {
var obj = {};
collection = key_to_collection[key];
obj[key] = collection;
if(localStorage.getItem(key) != null) {
var tmp = JSON.parse(localStorage.getItem(key));
for(var i = 0;i<tmp.length;i++) {
collection.push(tmp[i]);
}
}
collection.push(obj);
localStorage.setItem(key, JSON.stringify(collection));
});

If your variable name is title for example, then you can access it using window['title']. This means that if you define an array of your global variable names:
const varNames = ['title', 'brief', 'hover', ...]
Then you can do a loop like the following
for(const name of varNames) {
const value = window[name]
// do whatever you want using the variable name and value
}
I hope this solves your issue :)

comparate a elementes inside of an array for get a specific value appscript

I want to do a comparate a elementes inside of an array for get a specific value, how i could do it with this?
var data = sheet.getDataRange().getValues();
var dataToImport = {};
for(var i = 1; i < data.length; i++) {
dataToImport = {
Nivel:data[i][0],
Consumo:data[i][1],
Flujo:data[i][2],
if(dataToImport[Nivel]>99)
{
}

I'm not sure what your looking for but hopefully this will help.
function myfunction()
{
var ss=SpreadsheetApp.getActive();
var sh=ss.getActiveSheet();
var data=sh.getDataRange().getValues();
var dataToImport = {};
for(var i=1;i<data.length;i++)
{
dataToImport = {'Nivel':data[i][0],'Consumo':data[i][1],'Flujo':data[i][2]}
if(dataToImport['Nivel']>99)
{
Logger.log('Nivel greater than 99 dataToImport = %s', dataToImport);
}
Logger.log(dataToImport);
}
}

Return more than one values from a function in Javascript using for loop

I am using following code snippet and I am pretty sure I am doing something that wrong that is why it is not returning more than one values. I need experts opinion on it.
function returnValues(testArray)
{
var accountId, orders, abstractOrders, titleOrder;
var childOrders = new Array();
for(var i = 0; i < testArray.length; i++)
{
accountId = typeof testArray[i] === 'undefined'?'':testArray[i].id;
orders = getOrderofParentAccount(accountId);
abstractOrders = abstractOrderYTD(orders);
titleOrder = titleOrderYTD(orders);
childOrders[abstractOrders,titleOrder];
}
return childOrders;
}

You probably want to return an array of objects:
function returnValues(testArray)
{
var accountId, orders, abstractOrders, titleOrder;
var childOrders = new Array();
for(var i = 0; i < testArray.length; i++)
{
accountId = typeof testArray[i] === 'undefined'?'':testArray[i].id;
orders = getOrderofParentAccount(accountId);
abstractOrders = abstractOrderYTD(orders);
titleOrder = titleOrderYTD(orders);
childOrders.push({abstract: abstractOrders,title: titleOrder}); //<-Changed
}
return childOrders;
}
//To retrieve the values
var orders = returnValues(yourarray);
for( var i in orders ){
console.log("====="+i+"======");
console.log('Abstract Orders:');
console.log(orders[i].abstract);
console.log('Title Orders:');
console.log(orders[i].title);
}

Adding a running sum to a javascript object

I have a javascript object as below
var mydata=[
{"Club":"Blackburn","EventNo":1,"Pnts":3,"CumPnts":0},
{"Club":"Blackburn","EventNo":2,"Pnts":1,"CumPnts":0},
{"Club":"Blackburn","EventNo":3,"Pnts":4,"CumPnts":0},
{"Club":"Preston","EventNo":1,"Pnts":2,"CumPnts":0},
{"Club":"Preston","EventNo":2,"Pnts":4,"CumPnts":0},
{"Club":"Preston","EventNo":3,"Pnts":2,"CumPnts":0},]
I want to update the object so that CumPnts contains a running points total for each Club as below
{"Club":"Blackburn","EventNo":1,"Pnts":3,"CumPnts":3},
{"Club":"Blackburn","EventNo":2,"Pnts":1,"CumPnts":4},
{"Club":"Blackburn","EventNo":3,"Pnts":4,"CumPnts":8},
{"Club":"Preston","EventNo":1,"Pnts":2,"CumPnts":2},
{"Club":"Preston","EventNo":2,"Pnts":4,"CumPnts":6},
{"Club":"Preston","EventNo":3,"Pnts":1,"CumPnts":7},]
Any help would be much appreciated

Here is a function that loops through the list and updates it after it's been added. But I suspect that the events come in one at a time so there could be another function that can look the cumPtns obj and take from that. Here is for the current list.
var cumData = {};
var mydata=[
{"Club":"Blackburn","EventNo":1,"Pnts":3,"CumPnts":0},
{"Club":"Blackburn","EventNo":2,"Pnts":1,"CumPnts":0},
{"Club":"Blackburn","EventNo":3,"Pnts":4,"CumPnts":0},
{"Club":"Preston","EventNo":1,"Pnts":2,"CumPnts":0},
{"Club":"Preston","EventNo":2,"Pnts":4,"CumPnts":0},
{"Club":"Preston","EventNo":3,"Pnts":2,"CumPnts":0}];
function updateMyData() {
for (var i = 0; i < mydata.length; i++) {
var item = mydata[i];
if(cumData[item.Club] == undefined) {
cumData[item.Club] = {};
cumData[item.Club] = item.Pnts;
} else {
cumData[item.Club] = cumData[item.Club] + item.Pnts;
}
mydata[i].CumPnts = cumData[item.Club];
};
console.log(mydata);
//if you want to return it you can have this line below. Otherwise the object is updated so you'll probably want to do something with it once it's updated. Call back maybe?
return mydata;
}
updateMyData();

The first time it encounters a team it adds it to an array and so does with the corresponding cumPnts, so we can keep track of whether we checked a team earlier or not.
var tmArr = [];
var cumArr = [];
for(var i = 0; i < mydata.length; i++) {
var elm = mydata[i];
var club = elm.Club;
var points = elm.Pnts;
var idx = tmArr.indexOf(club);
if(idx > -1) {
cumArr[idx] += points;
elm.CumPnts = cumArr[idx];
}
else {
elm.CumPnts = points;
tmArr[tmArr.length] = club;
cumArr[cumArr.length] = points;
}
}

Merging arrays in JavaScript not working

When I try var a = ar_url2.concat(ar_desc2); to join my arrays into one it returns null. I'm sure it's trivial but I spent a few hours stuck on this now and an explanation as why this is happening would be great. In my code bellow I tried while(ar_url2.length)a.push(ar_url2.shift()); and it returns same null...
function agregar() {
var i = 0,
textarea;
var ar_desc = [];
while (textarea = document.getElementsByTagName('textarea')[i++]) {
if (textarea.id.match(/^desc_([0-9]+)$/)) {
ar_desc.push(textarea.id);
}
}
var desc_count_demo = document.getElementById('desc_count').value;
var desc_count = desc_count_demo - 1;
i = 0;
var ar_desc2 = [];
var campo = null;
while (i <= desc_count) {
campo = document.getElementById(ar_desc[i]).value;
ar_desc2[ar_desc[i]] = campo;
i++;
}
i = 0;
var input;
var ar_url = [];
while (input = document.getElementsByTagName('input')[i++]) {
if (input.id.match(/^url_([0-9]+)$/)) {
ar_url.push(input.id);
}
}
var url_count_demo2 = document.getElementById('url_count').value;
var url_count2 = url_count_demo2 - 1;
i = 0;
var ar_url2 = [];
while (i <= url_count2) {
campo = document.getElementById(ar_url[i]).value;
ar_url2[ar_url[i]] = campo;
i++;
}
// var a = Array.prototype.concat.call(ar_url2, ar_desc2);
while (ar_url2.length) a.push(ar_url2.shift());
function url(data) {
var ret = [];
for (var d in data)
ret.push(encodeURIComponent(d) + "=" + encodeURIComponent(data[d]));
return ret.join("&");
}
window.open('alta1.php?'+url(a));
}
EDIT: If I pass to function url(ar_url2) or url(ar_desc2) the returned values in the URL are
http://localhost/proj1/alta1.php?url_0=inpit&url_1=input
and
http://localhost/proj1/alta1.php?desc_0=input&desc_1=input
But still cannot merge both into one...

One thing I see is your ar_url Array is filled by:
while(input=document.getElementsByTagName('input')[i++]){
if(input.id.match(/^url_([0-9]+)$/)){
ar_url.push(input.id);
}
}
Since you the putting the whole id in the array, it will be filled with things like: 'url_0', 'url_1', 'url_2', etc...
Later you do:
ar_url2[ar_url[i]] = campo;
When you index into ar_url, you get out the 'url_XXX' strings. That means you are setting the 'url_XXX' properties on ar_url2 instead of filling in the elements of the array.
Try changing your second loop to:
while(input=document.getElementsByTagName('input')[i++]){
var result;
if(result = input.id.match(/^url_([0-9]+)$/)){
ar_url.push(+result[1]);
}
}
To use the value captured in the ([0-9]+) portion of the RegExp instead of the entire 'url_XXX' string.
