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 :)

I'm trying to filter in an array by data in another array using concat in a for loop. The elements of the following code are logging correctly, but the final array is logging an empty array.
function Shipments (){
var app = SpreadsheetApp;
var movementSS = app.getActiveSpreadsheet();
var infoSheet = movementSS.getSheetByName("Update Info");
var orderInfoSheet = movementSS.getSheetByName("Order Info");
var targetSheet = movementSS.getSheetByName("Shipments");
var ShipLogSS = app.openByUrl(URL).getSheetByName("Shipping Details");
var ShipArr = ShipLogSS.getRange(3,1,ShipLogSS.getLastRow(),ShipLogSS.getLastColumn()).getValues().
filter(function(item){if(item[1]!=""){return true}}).
map(function(r){return [r[0],r[1],r[2],r[4],r[10],r[11],r[16],r[18],r[23]]});
var supplierData = orderInfoSheet.getRange(3,6,orderInfoSheet.getLastRow(),1).getValues().
filter(function(item){if(item[0]!=""){return true}});
var supplierList = [];
for (var i in supplierData) {
var row = supplierData[i];
var duplicate = false;
for (var j in supplierList) {
if (row.join() == supplierList[j].join()) {
duplicate = true;
}
}
if (!duplicate) {
supplierList.push(row);
}
}
var supplierFilter = [];
for(var i = 0; i < supplierList.length; i++){
var shipments = ShipArr.filter(function(item){if(item[4]===supplierList[i][0]){return true}});
supplierFilter.concat(shipments);
}
Logger.log(supplierFilter);
}
Any help would be greatly appreciated!
You need to assign the result of concat onto the supplierFilter in order to see the changes in later iterations and in the outer scope.
You can also return the comparison done inside the .filter callback immediately, instead of an if statement - it looks a bit cleaner.
var supplierFilter = [];
for (var i = 0; i < supplierList.length; i++) {
var shipments = ShipArr.filter(function (item) { return item[4] === supplierList[i][0]; });
supplierFilter = supplierFilter.concat(shipments);
}
Logger.log(supplierFilter);
I need to retrieve variables from an URL.
I use this found function:
function getParams(str) {
var match = str.replace(/%5B/g, '[').replace(/%5D/g, ']').match(/[^=&?]+\s*=\s*[^&#]*/g);
var obj = {};
for ( var i = match.length; i--; ) {
var spl = match[i].split("=");
var name = spl[0].replace("[]", "");
var value = spl[1];
obj[name] = obj[name] || [];
obj[name].push(value);
}
return obj;
}
var urlexample = "http://www.test.it/payments/?idCliente=9&idPagamenti%5B%5D=27&idPagamenti%5B%5D=26"
var me = getParams(stringa);
The output is:
{"idPagamenti":["26","27"],"idCliente":["9"]}
But idCliente is always NOT an array, so i'd like to retrieve:
{"idPagamenti":["26","27"],"idCliente": 9 }
This is the fiddle example
function getParams(str) {
var match = str.replace(/%5B/g, '[').replace(/%5D/g, ']').match(/[^=&?]+\s*=\s*[^&#]*/g);
var obj = {};
for ( var i = match.length; i--; ) {
var spl = match[i].split("=");
var name = spl[0].replace("[]", "");
var value = spl[1];
obj[name] = obj[name] || [];
obj[name].push(value);
}
return obj;
}
var stringa = "http://www.test.it/payments/?idCliente=9&idPagamenti%5B%5D=27&idPagamenti%5B%5D=26"
var me = getParams(stringa);
$(document).ready(function(){
alert("testing");
console.log(me);
$(".a").html(JSON.stringify(me));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="a">
</div>
Someone can help me to modify code?
I think your facing a real paradigm problem. Why idCliente wouldn't be an array but idPagamenti would be. You should have all array or none but not both. getParams() function can make this choice for you and you should probably change the way you are working with this.
Anyway, here is a getParams() function that replace any single-valued array to a value. Note that if you have only one idPagamenti in your URI, you will also have a single value for idPagamenti instead of an array.
function getParams(str) {
var match = str.replace(/%5B/g, '[').replace(/%5D/g, ']').match(/[^=&?]+\s*=\s*[^&#]*/g);
var obj = {};
for ( var i = match.length; i--; ) {
var spl = match[i].split("=");
var name = spl[0].replace("[]", "");
var value = spl[1];
obj[name] = obj[name] || [];
obj[name].push(value);
}
Object.keys(obj).forEach(key => {
if (obj[key].length === 1) {
obj[key] = obj[key][0];
}
})
return obj;
}
var urlexample = "http://www.test.it/payments/?idCliente=9&idPagamenti%5B%5D=27&idPagamenti%5B%5D=26"
var me = getParams(stringa);
If you know that you will always get ids as parameters, you can also add a parseInt() for each parameter by replacing var value = spl[1]; with var value = parseInt(spl[1], 10);
I have this google spreadsheet script that pulls in json formatted book data. I have no problem displaying book title and author, but he "offerData" object can contain a different amount of elements (prices from sellers) depending on the book. Right now I created a loop and am storing the offerData values like so:
price[i] = offerdata.offers[i]["price"];
condition[i] = offerdata.offers[i]["condition"];
seller[i] = offerdata.offers[i]["seller"]["displayName"];
and am returning the data like this:
var resultRow = [[title, specstag, price[0], condition[0], seller[0], price[1], condition[1], seller[1], price[2], condition[2], seller[2]]];
Obviously this only returns 3 sellers with price, condition, seller info. The issue is that a book doesn't always have 3 sellers, it can be anywhere from 1 to 10 or so.
My question is how can I return all offerData (price/condition/seller) here? :
var resultRow = [[title, specstag, price[0], condition[0], seller[0], price[1], condition[1], seller[1], price[2], condition[2], seller[2]]];
--
function getBookDetails(isbn) {
// Query the book database by ISBN code.
if (isbn !== "") {
var url = "https://api.bol.com/catalog/v4/search/?apikey=myapi6&offers=all&format=json&q=" + isbn;
var response = UrlFetchApp.fetch(url);
var results = JSON.parse(response);
if (results.totalResultSize) {
// There'll be only 1 book per ISBN
var book = results.products[0];
// get Title and Authors
var title = (results.products[0]["title"]);
var specstag = (results.products[0]["specsTag"]);
var offerdata = results.products[0]["offerData"];
if (typeof offerdata.offers !== 'undefined' && offerdata.offers.length > 0) {
var arrayLength = offerdata.offers.length;
var price = [];
var condition = [];
var seller = [];
for (var i = 0; i < arrayLength; i++) {
price[i] = offerdata.offers[i]["price"];
condition[i] = offerdata.offers[i]["condition"];
seller[i] = offerdata.offers[i]["seller"]["displayName"];
}
}
}
var resultRow = [[title, specstag, price[0], condition[0], seller[0], price[1], condition[1], seller[1], price[2], condition[2], seller[2]]];
return resultRow;
}
}
the answer
var resultRow = [];
resultRow[0] = [];
resultRow[0][0]=title;
resultRow[0][1]=specstag;
for (var i = 0; i < arrayLength; i=1+3) {
resultRow[0][3*i+2]=price[i];
resultRow[0][3*i+3]=condition[i];
resultRow[0][3*i+4]=seller[i];
}
how you should think about it is to see the index of the elements in the array and then find relation between i and the index you want
var resultRow = [
[
title, //[0][0]
specstag, //[0][1]
price[0], //[0][2]
condition[0], //[0][3]
seller[0], //[0][4]
price[1], //[0][5]
condition[1], //[0][6]
seller[1], //[0][7]
price[2], //[0][8]
condition[2], //[0][9]
seller[2]//[0][10]
]
];
You might be looking for something like this;
var data = { title: null,
spcstag: null,
pcs: [],
};
offerData.offers.forEach( p => { var pcsData = {};
!!data.title || data.title = p.title;
!!data.specstag || data.specstag = p.specstag;
pcsData.price = p.price;
pcsData.condition = p.condition;
pcsData.seller = p.seller;
data.pcs.push(pcsData);
});
I faced the following functions (or method I don't what is right name of the ):
function getRowArray($scope, object, i){
i = i + 1;
var item = {};
var data = [];
var id = -1;
if ($scope.selectedType !== undefined) {
id = $scope.selectedType.id;
}
var rating = getRating($scope, object, id);
item['name'] = $scope.objectInfo[object]['name'];
item['objectId'] = rating.objectId;
item['hideRating'] = parseInt($scope.objectInfo[object].hideControls) & 1;
item['addInfo'] = rating.addInfo;
item['rating'] = rating.value;
item['ratingId'] = rating.id;
for (var i in $scope.objectInfo[object].childs) {
if ($scope.objectInfo[object].childs[i] == object){
continue;
}
data.push(getRowArray($scope, $scope.objectInfo[object].childs[i], i));
}
item['data'] = data;
return item;
}
and
function getTypeRow($scope, oobject, otype){
var item = {};
var data = [];
var rating = getRating($scope, oobject.id, otype.id);
item['name'] = otype.name;
item['objectId'] = rating.objectId;
item['typeId'] = rating.typeId;
item['ratingId'] = rating.id;
item['addInfo'] = rating.addInfo;
item['rating'] = rating.value;
// item['hideRating'] = parseInt($scope.objectInfo[object].hideControls);
return item;
}
I want to use the hideRating item from the first one in the second, I tried and added the commented line but I got an error it says the object is undifined, is it wrong like that or am I missing something ? thanks in advance
object is undefined because it wasn't initialized; it's not specified in the parameter list for the function getTypeRow. The oobject in the parameter list should be corrected to object:
// Correct 'oobject' to 'object'
function getTypeRow($scope, object, otype){
var item = {};
var data = [];
// Correct 'oobject' to 'object'
var rating = getRating($scope, oobject.id, otype.id);
...
}
function test(results) {
//Populate the ComboBox with unique values
var Gov;
var values = [];
var features = results.features;
var og;
for (i = 0; i < features.length; i++) {
var aGOV = {
"GovName": features[i].attributes.ENG_NAME,
"GovNO": features[i].attributes.GOV_NO,
"Shape": features[i].geometry
}
og = new Option(features[i].attributes.ENG_NAME, aGOV);
var cbx = document.getElementById("cbxGov");
cbx.options.add(og);
}
}
function gov_selection_change()
{
var cbx = document.getElementById("cbxGov");
var itm = cbx.options[cbx.selectedIndex].value.hasOwnProperty("Shape");
}
html code
<select id="cbxGov" onchange="gov_selection_change()">
My problem is i m not able to access property of aGOV in my gov_selection_change() function, it shows it has no such property, itm is false.
The value property of an HTMLOptionElement always returns a DOMString (a.k.a. text), not an object.
So you have to save what you want to access in a lookup dictionary and then use the returned value as a lookup key.
var lookupDictionary = {};
function test(results) {
var lookupKey,
og;
//...
// don´t get the element in the loop
var cbx = document.getElementById("cbxGov");
//...
for (i = 0; i < features.length; i++) {
lookupKey = features[i].attributes.GOV_NO;
lookupDictionary[lookupKey] = {
"GovName": features[i].attributes.ENG_NAME,
"GovNO": features[i].attributes.GOV_NO,
"Shape": features[i].geometry
}
og = new Option(features[i].attributes.ENG_NAME, lookupKey );
cbx.options.add( og );
}
}
function gov_selection_change() {
var cbx = document.getElementById("cbxGov");
var key = cbx.options[cbx.selectedIndex].value;
var itm = lookupDictionary[key].hasOwnProperty("Shape");
}
The variable aGOV is only available in the context of your result() function. If you want to use it from a different function declare it as a global variable.
Example:
var aGOV;
function result()
{
// initialize aGOV
}
function gov_selection_change()
{
// now you can access the aGOV variable
}
