I want to put number in the data type in html and use button to call the function to return the value to the variable.
function income(sumincome) {
var sumincome = 0
sumincome += parseInt(document.getElementById("income").value)
document.getElementById("resultin").innerHTML = (sumincome)
return sumincome;
}
function expenses() {
var sumexpenses = 0
sumexpenses += parseInt(document.getElementById("expen").value)
document.getElementById("resultexp").innerHTML = (sumexpenses)
return sumexpenses;
}
var net = income() - expenses();
that's very simple :
<!DOCTYPE HTML>
<html>
<body>
<script>
function income(sumincome) {
var sumincome = 10;
return sumincome;
}
function expenses() {
var sumexpenses = 5;
return sumexpenses;
}
var net = income() - expenses();
alert("Value Net : " + net);
</script>
</body>

I made a selectBox which had its range of values from a Google Sheet Column. I also want to take an Integer input value from the user and then write this value in a specific cell according to option taken from selectBox. The html link does not show the integer response box. Is it possible to do the above plan in a while loop? Would appreciate any ideas and correction of code
function doGet() {
var ap = SpreadsheetApp.openByUrl("Gsheet URL here");
var ui = SpreadsheetApp.getUi();
var user = ui.prompt("Put down a number");
var result = result.getSelectedButton();
var sheet = ap.getSheetByName("lv");
var values = sheet.getRange("A2:A10").getValues();
var options = values.map(function(row)
{
#To show show the selected option??
var item = options.getSelecteditem();
if (item === A3)
{
var cell = SpreadsheetApp.getActiveSheet().getActiveCell();
var a1 = cell.getA3Notation();
var val = cell.getValue();
SpreadsheetApp.getUi().alert("Ur value is "+a1+" value is "+val);
}
{
return '<option value="' + row[0] + '">' + row[0] + '</option>';
});
var html = '<form onSubmit="handleSubmit(this)"> Type of Cuisine' + options.join('') + '</select></form>';
return HtmlService.createHtmlOutput(html);
}
Using an Html Dialog to Control User Inputs
Not sure what you wanted so here's a complete example I whipped up for you.
Code.gs:
function processInput(obj) {
Logger.log(JSON.stringify(obj));
const ss = SpreadsheetApp.getActive();
const sh = ss.getSheetByName('Sheet0');
const [min,max,locs] = sh.getRange('B1:B3').getValues().flat();
Logger.log('min: %s max: %s locs: %s',min,max,locs)
const lA = locs.split(',');
if(obj.int > max) {
obj.msg = "Too High Try Again";
return obj;
} else if (obj.int < min) {
obj.msg = "To Low Try Again";
return obj;
} else if (!~lA.indexOf(obj.loc)) {
obj.msg = "Invalid Location";
return obj;
} else {
sh.getRange(obj.loc).setValue(obj.int);
obj.msg = "Complete";
return obj;
}
}
Following function Launches the dialog:
function launchInputDialog() {
SpreadsheetApp.getUi().showModelessDialog(HtmlService.createHtmlOutputFromFile('ah1'),"Enter Input");
}
html:
<!DOCTYPE html>
<html>
<head>

document.getElementById("msg").innerHTML = '';
let v1 = parseInt(document.getElementById('in1').value);
let v2 = document.getElementById('in2').value;
let obj = {int:v1,loc:v2,msg:''};
google.script.run
.withSuccessHandler(robj => {
console.log(JSON.stringify(robj))
if(robj.msg == "Complete") {
document.getElementById("msg").innerHTML = `Value: ${robj.int} Location: ${robj.loc} Try Again`;
document.getElementById("in1").value = '';
document.getElementById("in2").value = '';

Demo:
Good evening. I am new to JavaScript and I need help with my mini-project and I have only one issue here and it is in the this.Add = function ().
It works properly when I enter a duplicate value from my list therefore it displays an alert that no dupes are allowed. But... when I enter a unique value, it only adds up the last element present (Wash the dishes) from myTasks list. instead of the one I recently entered and the list goes on adding the same ones. Did I just misplace something?
This is my final activity yet and I want to finish it to move to the next function. Thank you in advance.

In your for loop:
for (task of this.myTask) {
}
You are not declaring a new task variable, but instead assigning to the outer task variable, hence the repeated addition of tasks already in your list.
You can declare a new variable in the for scope like so:
for (const task of this.myTask) {
}
Your HTML as it is.
And your Javascript goes like below. You have a bug while checking if the task already exists in the array. As you're comparing string value either use simple for loop with triple equals or do as i have attached below.
var app = new function() {
this.el = document.getElementById('myTasks');
this.myTasks = ['Clean the bathroom', 'Wash the dishes'];
this.Count = function(data) {
var el = document.getElementById('counter');
var name = 'task';
if (data) {
if (data > 1) {
name = 'Things To DO';
}
el.innerHTML = data + ' ' + name ;
} else {
el.innerHTML = 'No ' + name;
}
};
this.FetchAll = function() {
var data = '';
if (this.myTasks.length > 0) {
for (i = 0; i < this.myTasks.length; i++) {
data += '<tr>';
data += '<td>' + this.myTasks[i] + '</td>';
data += '<td><button onclick="app.Edit(' + i + ')">Edit</button></td>';
data += '<td><button onclick="app.Delete(' + i + ')">Delete</button></td>';
data += '</tr>';
}
}
this.Count(this.myTasks.length);
console.log(this.myTasks.length);
return this.el.innerHTML = data;
};
this.Add = function () {
el = document.getElementById('add-task');
// Get the value
var task = el.value;
console.log(task);
if (task ){
var arrayContainsTask = (this.myTasks.indexOf(task) > -1);
if(arrayContainsTask == true){
window.alert("Duplicates not allowed.");
}else{
// Add the new value
this.myTasks.push(task);
// Reset input value
el.value = '';
}
// Dislay the new list
this.FetchAll();
}
}
}

This code should take a template (String), parameters (String word out of text) and data (String) as input to then replace al the parameters in the text by the String data. I do get an error which I can't figure out at the first line in the last function:

I hope somebody knows why I get this error.
It seems like your 'update' should be
function update() {
var parameterDataKoppels = [];
var rangnummerKoppel = 1;
for(var i = 0; i < aantalKoppels - 1; i++) {
var parameter = (document.getElementById("parameter" + rangnummerKoppel)).value;
var data = (document.getElementById("data" + rangnummerKoppel)).value;
parameterDataKoppels[i] = [parameter.trim(), data.trim()];
rangnummerKoppel++;
}
//var template = document.getElementById("template");
var template = document.getElementById("template").value;
vervangAlles(template, parameterDataKoppels);
}
UPDATE: SOLVED! line 116 (ERROR3) had to be changed from 'parseInst(rom[i]); ' to 'rom[i]; '.
I'm working on an assembly simulator in Javascript. For some reason the JUMP instruction messes up the register contents. The following program (can be copy-pasted) increments register 'A' (0-->1) then jumps to instruction 0. Instead of '1', the register's content becomes a value over 5000. What am I doing wrong?

Would anyone clerify why my program is outputting undefined or NAN? I know for sure that my random number generator is working. Also, I'm trying to sum up all of the "score" value when the number generator has generated the value 10 times. Thanks for the help

Because score variable is undefined. You should initialize it with a number for instance: var score = 0;
Variable score is declared in your totalscore function but never initialised. Adding anything to undefined gives NaN, which is what your function writes to the page.
You need to initialize your score variable with 0. Until you don't, it's value is undefined and when you do math operations on an undefined object, you wil get a NaN error. I have also formatted your code a bit.
