I need to display a date from an array and it needs to be incremented for each input by 1 day. The date should display as mm/dd/yyyy. I was able to get the date to display correctly with the code that is in the message but after each input the all the dates would increment. I need just the last input to increment a day and I thought putting it in an array would work but now nothing displays. Thanks for helping.
var lowTempArray = [];
var highTempArray = [];
var nowArray = [];
function process() {
'use strict';
//declare variables
var lowTemp = document.getElementById('lowTemp');
var highTemp = document.getElementById('highTemp');
var output = document.getElementById('output');
var date = new Date();
var message = ' ';
if (lowTemp.value) {
lowTempArray.push(lowTemp.value);
if (highTemp.value) {
highTempArray.push(highTemp.value);
message = '<table><th>Date </th><th> Low Temperatures</th><th> High Temperatures</th>';
for (var i = 0, count = lowTempArray.length; i < count; i++) {
for (var i = 0, count = highTempArray.length; i < count; i++) {
for (var i = 0, count = nowArray.length; i < count; i++) {
nowArray.push(new Date(date.getTime()));
date.setDate(date.getDate() + count);
message += '<tr><td>' + ((nowArray.getMonth() + 1) + '/' + (nowArray.getDate() + count) + '/' + nowArray.getFullYear()) + '</td><td> ' + lowTempArray[i] + '</td><td> ' + highTempArray[i] + '</td></tr>';
}
message += '</table>';
output.innerHTML = message;
}
}
}
}
return false;
}
function init() {
'use strict';
document.getElementById('theForm').onsubmit = process;
} // End of init() function.

I need to assign instances of my object as values in my array, but when I try to add let to my loop for collecting user input, I get an error stating that "[" is an unexpected token. This is a new technique to me so I'm not sure if this is even a practical method for making a table. Any help is appreciated.
<script>
function generateTable() {
var tblStart = "<table>";
//This is the header line for my table.
var tblMeat = "<tr> <td><b>Name</b></td> <td><b>Attendance</b></td> <td><b>Homework</b></td> <td><b>Midterm</b></td> <td><b>Final</b></td> <td><b>Course Grade</b></td> <td><b>Round Grade</b></td> <td><b>Letter Grade</b></td> </tr>";
var tblStop = "</table>";
//This determines the number of rows.
var rowCount = prompt("How many students are in the class?");
//I want to assign instances of Student to this array which will be used to fill the table cells.
var pupil = [NUMBER(rowCount)];
//This object should process user entries and use them to calculate the total grade, rounded grade, and letter grade.
function Student(name, attendance, homework, mGrade, fGrade) {
this.name = name;
this.attend = attendance;
this.homewrk = homework;
this.midter = mGrade;
this.fingrad = fGrade;
this.course = function () {
var attGrade = this.attend * 0.1;
var hwkGrade = this.homewrk * 0.2;
var midGrade = this.midter * 0.3;
var finGrade = this.fingrad * 0.4;
var combGrade = attGrade + hwkGrade + midGrade + finGrade;
return combGrade.toFixed(2);
};
this.round = Math.round(this.course);
this.letter = function() {
if(this.course < 60) {
return '<p style="color:red;">F</p>';
} else if(this.course >= 60 && this.course <= 69.9){
return "D";
} else if(this.course >= 70 && this.course <= 79.9) {
return "C";
} else if(this.course >= 80 && this.course <= 89.9) {
return "B";
} else if(this.course >= 90 && this.course <= 100) {
return "A";
};
};
}
/*This loop should collect user input based on the declared number of students, and assign input values to instances of

I ran your program through uglifyJS. It's actually for compressing javascript code, but when there is a lot of code to debug, it's a life changer.
The script told me:
Parse error: Unexpected token: punc ([)
Line 59, column 16
let pupil[r] = new Student(studentN, studentA, studentH, studentM, studentF);
You're trying to define an already existing variable. Remove "let".

My Javascript/GAS code uses the user ID to call for time entries via API for a specific date range (1 week) and sum up the hours. These time entries are saved in an array and then summed up. The first 50 additions on the log are correct but as you go through the list you realize wrong summed figures and long decimal places. What could be wrong and what can I do to solve this. Here is my code:
var TKF_URL = 'https://api.10000ft.com/api/v1/';
var TKF_AUTH = 'auth'
var TKF_PGSZ = 2500
var from = '2020-01-06'
var to = '2020-01-22'
var options = {
method: 'get',
headers: {
Authorization: 'Bearer ' + TKF_AUTH
}
};
function getUsers() {
var userarray = [];
var lastpage = false;
var page = 1;
do {
// gets 10kft data
var users = read10k_users(page);
// writes data from current page to array
for (var i in users.data) {
var rec = {};
// pushing of mandatory data
rec.id = users.data[i].id;
rec.display_name = users.data[i].display_name;
rec.email = users.data[i].email;
userarray.push(rec);
}
// checks if this is the last page (indicated by paging next page link beeing null
if (users.paging.next != null) {
lastpage = false;
var page = page + 1;
} else {
lastpage = true;
}
}
while (lastpage == false);
return (userarray);
return (userarray);
}
function read10k_users(page) {
var endpoint = 'users?';
var url = TKF_URL + endpoint + 'per_page=' + TKF_PGSZ + '&auth=' + TKF_AUTH + '&page=' + page;
var response = UrlFetchApp.fetch(url, options);
var json = JSON.parse(response);
//Logger.log(json.data)
return (json);
}
function showTimeData() {
var users = getUsers()
var endpoint = 'users/';
var time_array = [];
for (var i = 0; i < users.length; i++) {
var total_hours = 0;
// Logger.log(users[i].id)
var url = 'https://api.10000ft.com/api/v1/users/' + users[i].id + '/time_entries?fields=approvals' + '&from=' + from + '&to=' + to + '&auth=' + TKF_AUTH;
var response = UrlFetchApp.fetch(url, options);
var info = JSON.parse(response.getContentText());
var content = info.data;
for (var j = 0; j < content.length; j++) {
total_hours += content[j].hours;
// }
//
// if(total_hours < 35){
//
// sendMail(user[i]);
//
// }
Logger.log('User name: ' + users[i].display_name + ' ' + 'User id: ' + users[i].id + ' ' + 'total hours: ' + total_hours)
}
}
function sendMail(user) {
var emailAddress = user.email;
var message = 'Dear ' + user.display_name + 'Your timesheets is incomplete , please visist 10k Ft and commlete your timesheet'
var subject = 'TimeSheet';
MailApp.sendEmail(emailAddress, subject, message);
}
}

You have total_hours declared outside of your loop. So what you are doing is calculating the total hours all workers combined, not total hours per worker.
(removed a lot of code to show only the important parts for your bug)
function showTimeData() {
var users = getUsers()
var total_hours = 0; // you declare the variable here
for (var i = 0; i < users.length; i++) {
var content = info.data;
// Calculate the sum for current user
for (var j = 0; j < content.length; j++) {
total_hours += content[j].hours;
}
// Check if total_hours for ALL workers is less than 35
if (total_hours < 35) sendMail(user[i]);
// total_hours is not reset, so the sum is used in next iteration.
}
}
Move the declaration of total_hours to inside the loop, or reset it to zero.
function showTimeData() {
for (var i = 0; i < users.length; i++) {
var total_hours = 0; // you declare the variable here
}
}
Your loop should look something like this:
for (var i = 0; i < users.length; i++) {
var total_hours = 0;
var url = "https://api.10000ft.com/api/v1/users/" + users[i].id + "/time_entries?fields=approvals" + "&from=" + from + "&to=" + to + "&auth=" + TKF_AUTH;
var response = UrlFetchApp.fetch(url, options);
var info = JSON.parse(response.getContentText());
var content = info.data;
for (var j = 0; j < content.length; j++) {
total_hours += content[j].hours;
}
if (total_hours < 35) {
sendMail(user[i]);
}
Logger.log("User name: " + users[i].display_name + " " + "User id: " + users[i].id + " " + "total hours: " + total_hours);
}
I cant solve this homework that needs to ask the user to enter student marks and output the minimum mark of the student, can someone please help me solve this problem:
<script>
function getMarks() {
var marks = prompt('Type the students marks, seperate each student mark with comma, do not write the percentage mark % .').split(',');
return marks;
}
var studentMarks = getMarks();
var arrayLength = studentMarks.length;
var studentNumber = 0;
var msg = '';
var i;
for (i = 0; i < arrayLength; i++) {
studentNumber = (i + 1);
msg += 'student ' + studentNumber + ': ';
msg += studentMarks[i] + '%' + '<br />';
} document.getElementById('marks').innerHTML = msg; document.getElementById('marke').innerHTML = math.min.apply(null, studentMarks) + '%';
</script>
I will do that in the following way:
function getMarks() {
var marks = prompt('Type the students marks, seperate each student mark with comma, do not write the percentage mark % .');
return marks.split(',').map(n => Number(n));
}
var marksArray = getMarks();
var studentMarks = Math.min(...marksArray);
var position = marksArray.indexOf(studentMarks);
var msg = 'Student ' + Number(position + 1) + ': ';
document.getElementById('marks').innerHTML = msg + studentMarks + '%';
<p id="marks"></p>
The user should be able to enter in an integer and see the base, squared, and cubed result of that number. The base result should be listed under the "base" header, the squared result should be listed under the "squared" header and the cubed result should be listed under the "cubed" result. However, my output is listed all results under the "base" header. How can I make the results be listed under the related headers? This is what I have:
var $ = function (id) {
return document.getElementById(id);
}
var calculate = function () {
//Get the input from the user and assign it to the userInput variable
var integer = $("integer").value;
var header = "Base" + " " + "Square" + " " + "Cubed" + "\n";
var squared = "";
var cubed = "";
var base = "";
var displayOutput;
for (var i = 1; i <= integer; i++) {
base += i + "\n";
squared += i * i + "\n";
cubed += i * i * i + "\n";
displayOutput = base + squared + cubed;
}
$("output").value = header + displayOutput;
}
var form_reset = function () {
$("output").value = "";
$("integer").value = "";
}
//Assign event handlers to their events
window.onload = function () {
$("powers").onclick = calculate;
$("clear").onclick = form_reset;
}
It all depends on the output. Trying to stay as close as possible to your code, seems you are inserting your resulting displayOutput string into a textarea control. If you want to keep it that way, try tabs (\t) to separate your columns, and only a new line at the end (\n). Also, I noticed you were concatenating every column (base, square, and cubed) on every iteration, so I removed that. Here's the result:
var $ = function (id) {
return document.getElementById(id);
};
var calculate = function () {
//Get the input from the user and assign it to the userInput variable
var integer = $("integer").value;
var header = "Base" + " " + "Square" + " " + "Cubed" + "\n";
var squared = "";
var cubed = "";
var base = "";
var displayOutput = "";
for (var i = 1; i <= integer; i++) {
base = i + "\t";
squared = i * i + "\t";
cubed = i * i * i + "\n";
displayOutput += base + squared + cubed;
}
$("output").value = header + displayOutput;
};
var form_reset = function () {
$("output").value = "";
$("integer").value = "";
};
//Assign event handlers to their events
window.onload = function () {
$("powers").onclick = calculate;
$("clear").onclick = form_reset;
$("theform").onsubmit = function() { return false; };
};
I'm using a server-side JS for a counter:
var date = new Date(2013,1,01);
var now = new Date();
var number = 0;
var increment = 3290;
var second = 1;
var secondTotal = (now.getTime()-date.getTime())/1000;
var incrementTotal = (secondTotal/1)*3290;
number = Math.round(number+incrementTotal);
function init() {
document.getElementById("kwh_fam_an").innerHTML = number;
setInterval('incrementation()',second*1000);
}
function incrementation() {
number = number+increment;
document.getElementById("kwh_fam_an").innerHTML = number;
}
I'm trying to change the format by forcing a colon and a space every 3 figures but the code below doesn't work:
function lisibilite_nombre(nbr) {
var number = '' + nbr;
var retour = '';
var count = 0;
for (var i = number.length - 1; i >= 0 ; i--) {
if (count != 0 && count % 3 == 0)
retour = number[i] + ' ' + retour ;
else
retour = number[i] + retour ;
count++;
}
alert('nb : ' + nbr + ' => ' + retour);
return retour;
}
Do you have any idea ?
You're adding the space but not the colon. Change:
retour = number[i] + ' ' + retour ;
to:
retour = number[i] + ': ' + retour;
