So i'm trying a simple cookie exercise and when i hit submit it returns undefined. Also is there a way to check what in a cookie in visual studio code?
function setcookie()
{
var tmr = new Date();
tmr.setDate(tmr.getDate() + 1);
document.cookie = "username="+ document.getElementById("username").innerHTML +";path=/";
document.cookie = "password="+ document.getElementById("password").value +";path=/";
}
function getcookie()
{
var Carray = document.cookie.split(";");
for(i = 0 ; i < Carray.length ; i++)
{
var valuearray =Carray[i].split("=")
if (valuearray == "username")
{
var name = valuearray[1];
}
else if (valuearray == "password")
{
var password = valuearray[1];
}
}
alert("username is " + name +" password is " + password);
}
valuearray will be a array, so you need to check valuearray[0] in the if condition.
var valuearray = Carray[i].split("=")
if (valuearray[0] == "username"){ //Here, valuearray[0]
var name = valuearray[1];
} else if (valuearray[0] == "password"){
var password = valuearray[1];
}
Try this
function getcookie() {
const Carray = document.cookie.split(";");
const [name, password] = Carray.map(item => item.split('=')[1])
console.log("username is " + name +" password is " + password);
}
or if you want to transform your cookies into object use this code
function getcookie()
{
var Carray = document.cookie.split(";");
var cookieObj = Carray.reduce((cookieObj, current) => {
const [key, value] = current.split('=');
return { ...cookieObj, ...{ [key]: value } }
}, {})
console.log("username is " + cookieObj.username +" password is " + cookieObj.password);
return cookieObj;
}
// result
{
username: 'usersname'
password: 'userspassword'
}
Please return your result from the functions, I'm not returning anything because I'm trying to match your code.
and answer to your second question. yes you can get value from vscode but for that you need to start your debugging mode
name and password are declared in the block of for, but you use them in out of the block.
change getcookie function to this:
var name="";
var password ="";
for(i = 0 ; i < Carray.length ; i++)
{
var valuearray =Carray[i].split("=")
if (valuearray == "username")
{
name = valuearray[1];
}
else if (valuearray == "password")
{
password = valuearray[1];
}
}
alert("username is " + name +" password is " + password);

Welcome to SO!
It looks like your function is pushing the data to clientArray regardless of the output of the checkName() function, for example. Whatever value the user submits will be added because the output of checkName() is evaluated after the push. Here's one solution:
//FirstName
let theirName = false;
while (!theirName) {
let firstName = await input("Please enter your first name: ");
theirName = checkName(firstName);
if (!theirName) {
output("Your first name contained numeric. Please re-enter your name without a numeric! ");
} else {
clientArray.push(firstName);
output("Your first name is: " + firstName);
}
}
This only pushes the data to clientArray once we know that the name has only valid characters within it.
I also looked through your checkName() function. While your solution is functional, it might be more elegant to check against a regular expression (like in the other functions). I've included a solution for your scenario below.
function checkName(nameCheck) {
let nameValue = /[0-9]+/;
if (nameCheck.match(nameValue)) {
return false;
} else {
return true;
}
}
var objLogin = [{
fname: "sastry",
book: "sastry"
}, {
fname: "laxman",
book: "laxman"
}, {
fname: "visali",
book: "visali"
}]
function storeData() {
var userName = document.getElementById("fname").Value;
var userPasswd = document.getElementById("book").Value;
for (i = 0; i < objLogin.length; i++) {
if (userName == objLogin[i].fname && userPasswd == objLogin[i].book) {
console.log(userName + "Is logged in!!");
return;
} else {
console.log("Incorrect username or password");
}
}
}
When accessing the value of an input field, you should use value (lower case "v").
var userName = document.getElementById("fname").value;
Also, it's great to cache your element references, like this:
const userNameInput = document.getElementById("fname");
const userPasswdInput = document.getElementById("book");
function storeData() {
const userName = userNameInput.value;
const userPasswd = userPasswdInput.value;
for (i = 0; i < objLogin.length; i++) {
if (userName === objLogin[i].fname && userPasswd === objLogin[i].book) {
console.log(userName + "Is logged in!!");
return;
} else {
console.log("Incorrect username or password");
}
}
}
I think there is some typo.
var userName = document.getElementById("fname").Value;
var userPasswd = document.getElementById("book").Value;
As far as I know, document.getElementById("something").value is right;
Oh, someone answer that, but it's my first time to use stack overflow,
how can I do?
I have an issue with a custom google script I'm making to generate a bunch of sheets with info based on other sheets. I can't figure out why this is happening..
I've tried including logs and the values before the return is correct.. however when its returned, I get the value undefined.
it's regarding the function: getTournamentInfo(), called from tournamentInfo = getTournamentInfo(matchInfo[0]);
function getTournamentInfo(abbreviation) {
var sheet = ss.getSheetByName("Tournaments");
var tournaments = sheet.getRange("B2:B").getValues().filter(String);
console.log("Fetching Abbreviation: " + abbreviation);
var r = 2;
tournaments.forEach(function (tournament) {
if (tournament != "")
{
var tInfo = sheet.getRange("B"+r+":K"+r).getValues().toString().split(",");
if (tInfo[0] == abbreviation) {
console.log("Returning Info for: " + tInfo[0]);
return tInfo;
}
}
});
}
function generateSheets() {
var sheet = ss.getSheetByName("Match Schedule");
var matches = sheet.getRange("B5:B").getValues().filter(String);
var r = 5;
matches.forEach(function (match) {
if (match != "")
{
var matchInfo = sheet.getRange("B"+r+":L"+r).getValues().toString().split(",");
if (matchInfo[10] == "true") // Checks wether or not to generate the sheet
{
console.log("Generate = " + matchInfo[10]);
console.log("Fetching Tournament Info: " + matchInfo);
var tournamentInfo = "";
try {
tournamentInfo = getTournamentInfo(matchInfo[0]);
} catch (e) {
console.log(e);
}
console.log(tournamentInfo);
var template = "1v1PlayerTemplate"; // Default Template
if (tournamentInfo[3] == 2) {
template = "1v1TeamTemplate";
} else if (tournamentInfo[3] == 3) {
template = "XvXTeamTaplte";
}
var sheetName = matchInfo[0] + " | " + matchInfo[1];
var matchSheet = ss.getSheetByName(template).copyTo(ss.getSheetByName(template).getParent()).setName(sheetName);
}
}
r++;
});
}```
Your getTournamentInfo function is not returning your result. Your return statement only short-circuits the function supplied in forEach. This is one of the possible solutions (untested):
function getTournamentInfo(abbreviation) {
var sheet = ss.getSheetByName("Tournaments");
var tournaments = sheet.getRange("B2:B").getValues().filter(String);
console.log("Fetching Abbreviation: " + abbreviation);
var r = 2;
let result; // <----
tournaments.forEach(function (tournament) {
if (tournament != "" && result == undefined) { // <-----
var tInfo = sheet.getRange("B" + r + ":K" + r).getValues().toString().split(",");
if (tInfo[0] == abbreviation) {
console.log("Returning Info for: " + tInfo[0]);
result = tInfo; // <----
}
}
});
return result; // <----
}
You can do it more simply with a for loop, instead of forEach:
function getTournamentInfo(abbreviation) {
var sheet = ss.getSheetByName("Tournaments");
var tournaments = sheet.getRange("B2:B").getValues().filter(String);
console.log("Fetching Abbreviation: " + abbreviation);
var r = 2;
for (const tournament of tournaments) { // <==============
if (tournament != "") {
var tInfo = sheet.getRange("B" + r + ":K" + r).getValues().toString().split(",");
if (tInfo[0] == abbreviation) {
console.log("Returning Info for: " + tInfo[0]);
return tInfo;
}
}
}
}
Please, help.
Why are numbers displayed without a space?
How to make phone numbers displayed through a space?

re("ADD Ivan 555-10-01,555-10-03");

Your code works as expected. If you just need the phone numbers printed then get the value of the phone number by accessing it:
var phoneBook = {};
function re(command) {
if (command.split(" ")[0] == "ADD") {
var name = command.split(" ")[1];
var numb = command.split(" ")[2].split(",");
if (!phoneBook.hasOwnProperty(name)) {
phoneBook[name] = numb;
return phoneBook[name];
} else {
phoneBook[name] = phoneBook[name].concat(numb);
return Object.keys(phoneBook) + ": " + phoneBook[name];
}
}
if (command.split(" ")[0] == "SHOW") {
var book = [];
for (i = 0; i < Object.keys(phoneBook).length; i++) {
var key = Object.keys(phoneBook)[i];
book[i] = [key + ": " + phoneBook[key]];
}
return book;
}
}
re("ADD Ivan 555-10-01,555-10-03");
re("ADD Ivan 555-10-02");
//get the full result
console.info(re("SHOW"));
console.info(re("SHOW")[0][0]);

henry, clay, 034.146.412, hclay#example.ca , ibc233 , oop244 , dbs201 , int222
When the program asks to enter the course code; it is suppose to see if the students have that course and only if they do, it prints that students info.
In my case, even if student does not have the course it still prints it.
Please run the code to see if it makes more sense... I can't explain any better
The problem can be reduced to this:
var Foo = {
courses: []
};
var x = Object.create(Foo);
var y = Object.create(Foo);
x.courses.push(123);
alert(y.courses[0]); // "123"
The reason for this behaviour is that both objects inherit the same prototype and any changes made to .courses will apply to both objects.
For this reason, it would be better to create a constructor function instead:
function Foo()
{
this.courses = [];
}
var x = new Foo();
