Value passed from textbox to textarea is automatically deleted - javascript

I am trying to pass a value entered in a textbox to a text area. However when I run my code the value appears in the textarea and it disapears.
Html code:
Customer Name
<input type="text" id="name1TXT" />
<textarea rows="6" cols="50" id="productList">
</textarea>
Javascript:
function transferData() {
var customer = document.getElementById("name1TXT").value;
if (customer != "")
document.getElementById('productList').value += customer + ","
document.getElementById('name1TXT').value = "";
}
Does anyone know why this would happen?
Edit
Here is all of my code.

I cannot comment but I created as JSBin and seems to be working. I wasn't for sure how you are calling the transferData function to see the textarea clear so I just added an onBlur event to the input textbox.
I also added a semicolon to the line clearing the name1TXT value.
I still think everything is working regarding your code. By that I mean there aren't any odd bugs. But what exactly are you trying to accomplish? There appears to be 3 Customer Name boxes but when you click submit only 1 is being output into the textarea. It only grabs Customer1 and puts his/her name into the textarea and this process is repeating with each Submit. Are you trying to add all 3 customers? If so, then you will need more logic in your transferData function

you should use value like this
document.getElementById("writeArea").value = txt;
or like this in jQuery:
$('#myTextarea').val('');

Can I append/push values of html elements to each row of an array generated from a html table within the form?

I'm doing a html form for online requests by users. The form has text input fields for user contact details (e.g. user name, department, email, etc) at the top, followed by a table with multiple rows for different items requested.
I want to have the form data appended into Google Sheets, where each table row (item requested) is appended as a separate row in Sheets, with the user contact details added to each row, i.e. the contact details have to repeat for the same user.
Link to Sheet
Tried Google Forms -- it's good for single item requests -- one Google Form for one item. But for multiple item requests by the same user, the user has to key in contact details repeatedly. Branching to repeat sections in Forms didn't work, since additional items are added as new columns and not as a new row. Thus I tried a rudimentary html form.
FormTableDialog
Code.gs:
function addRows(valuesAll) {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1");
sheet.getRange(sheet.getLastRow()+1,1,valuesAll.length,valuesAll[0].length).setValues(valuesAll);
}

Tried to simply concat the id's of the user details, with the table array. But the google script didn't work. Appreciate any suggestions for this newbie.

There are two problems with the OPs code.
1 - output is not adjusted for Google's two-dimensional range.
2 - the Name, phone, email and department are not collected.
The following answer is written to work in the sidebar (not essential) and also tests whether the form data is complete - that is: whether there is complete data for the Item, Description, Quantity and Location in each row . The OP can easily remove this test.

How to calculate to variable in javascript and print them in the html page

I try to get result from html table witch excepted only numbers i check them throw if statement if variable 1 bigger than variable 2 print content and that works good.
Now i am trying in the if statement to print variable 1 - variable 2 but it doesn't wanna work.
Here is the snippet:
$(document).ready(function() {
var vastInkomen = 0;
$('.txtBox').keyup(function() {
vastInkomen = 0;
$('.txtBox').each(function() {
var txtBoxVal = $(this).val();
vastInkomen += Number(txtBoxVal);
});
$('#vastInkomen').val(vastInkomen);
writeResult();
});
var vastLasten = 0;
$('.vast_lasten').keyup(function() {
vastLasten = 0;
$('.vast_lasten').each(function() {
var vastLastenVal = $(this).val();
vastLasten += Number(vastLastenVal);
});
$('#vastLasten').val(vastLasten);
writeResult();
});
function writeResult() {
if (vastInkomen !== 0 && vastLasten !== 0) {
if (vastInkomen > vastLasten) {
$('#result').text("Some text and work good!") +
vastLasten - vastInkomen;
} else if (vastInkomen < vastLasten) {
//$('#result-amount').console(vastInkomen -vastLasten);
$('#result').text("some text and work good.");
}
}
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table>
<tr>
<td>content1</td>
<td><input class="txtBox" type="number" name="content2" />
</td>
</tr>
<tr>
<td>content3</td>
<td><input class="txtBox" type="number" name="content3" />
</td>
</tr>
<tr>
<td>content4</td>
<td>
<input class="txtBox" type="number" name="content4" />
</td>
</tr>
</table>
<table>
<tr>
<td>content</td>
<td><input class="vast_lasten" type="number" name="content" /></td>
</tr>
<tr>
<td>content1</td>
<td><input class="vast_lasten" type="number" name="content1" /></td>
</tr>
<tr>
<td>content2</td>
<td><input class="vast_lasten" type="texnumber" name="content2" /></td>
</tr>
</table>
<div class="col">
<h3>Het resultaat is:</h3>
<p id="result"></p>
</div>
This will work:
var result = vastLasten - vastInkomen;
$('#result').text("Some text and work good!" + result);
You can use .text() to set the content of an element, but everything should be within the parenthesis.
I added an extra variable result because you cannot use + and - both here; it will result in NaN as it will try to sum the values.
This works as well:
$('#result').text("Some text and work good!" + (vastLasten - vastInkomen));

Simple multiplication calculator not retaining decimal value

This is a simple multiplication calculator which on typing automatically adds comma to separate groups of thousands. However it doesn't accept decimal value for example 1,778.23. Copy pasting it directly into the field works but can't type it. Any solution would be much appreciated.
function calculate() {
var myBox1 = updateValue('box1');
var myBox2 = updateValue('box2');
var myResult = myBox1 * myBox2;
adTextRes('result', myResult)
}
function updateValue(nameOf) {
var inputNo = document.getElementById(nameOf).value;
var no = createNo(inputNo);
adTextRes(nameOf, no);
return no;
}
function adTextRes(nameOf, no) {
var asText = String(no).replace(/\B(?=(\d{3})+(?!\d))/g, ",");
document.getElementById(nameOf).value = asText;
}
function createNo(textin) {
return Number(textin.replace(/,/g, ""));
}
<table width="80%" border="0">
<tr>
<th>Box 1</th>
<th>Box 2</th>
<th>Result</th>
</tr>
<tr>
<td><input id="box1" type="text" oninput="calculate()" /></td>
<td><input id="box2" type="text" oninput="calculate()" /></td>
<td><input id="result" /></td>
</tr>
<tr>
<td> </td>
<td> </td>
<td> </td>
</tr>
</table>
The problem is, in createNo:
return Number(textin.replace(/,/g, ""));
A trailing period will just get discarded when converted to a Number. There's no need for such a casting in the first place, though - just leave it off, and it'll work as expected:
function createNo(textin) {
return textin.replace(/,/g, "");
}
To prevent multiple decimal points from being entered, you can use another replace in the same function:
.replace(/(\.\d*)\./, '$1')
function calculate() {
var myBox1 = updateValue('box1');
var myBox2 = updateValue('box2');
var myResult = myBox1 * myBox2;
adTextRes('result', myResult)
}
function updateValue(nameOf) {
var inputNo = document.getElementById(nameOf).value;
var no = createNo(inputNo);
adTextRes(nameOf, no);
return no;
}
function adTextRes(nameOf, no) {
var asText = String(no).replace(/\B(?=(\d{3})+(?!\d))/g, ",");
document.getElementById(nameOf).value = asText;
}
function createNo(textin) {
return textin
.replace(/,/g, "")
.replace(/(\.\d*)\./, '$1')
}
<table width="80%" border="0">
<tr>
<th>Box 1</th>
<th>Box 2</th>
<th>Result</th>
</tr>
<tr>
<td><input id="box1" type="text" oninput="calculate()" /></td>
<td><input id="box2" type="text" oninput="calculate()" /></td>
<td><input id="result" /></td>
</tr>

It does this but it does it for anything less than 30 as well. Also I am having trouble with my submit button sending off to a server/url. Any help is appreciated! I will attach my code!

Problem with your values qty1,qty2,qty3. these values are reading as string. so instead of addding these values , its concatinating the strings. replace
var qty1 = document.getElementById("Quantity1").value;
var qty2 = document.getElementById("Quantity2").value;
var qty3 = document.getElementById("Quantity3").value;
with
var qty1 = parseInt(document.getElementById("Quantity1").value);
var qty2 = parseInt(document.getElementById("Quantity2").value);
var qty3 = parseInt(document.getElementById("Quantity3").value);
It will Solve your problem with 'Red'.
For the submit button, function total() is not returning anything. so change something like
function total() {
var p1 = document.getElementById("Price1").value; //Value is referenced to the input tag
var p2 = document.getElementById("Price2").value;
var p3 = document.getElementById("Price3").value;
var qty1 = parseInt(document.getElementById("Quantity1").value);
var qty2 = parseInt(document.getElementById("Quantity2").value);
var qty3 = parseInt(document.getElementById("Quantity3").value);
var over = qty1 + qty2 + qty3;
if (realNumber()) {
var totals = (p1 * qty1) + (p2 * qty2) + (p3 * qty3);
var yes = (totals).toFixed(2);
document.getElementById("ProductTotal").innerHTML = "$" + yes;
if (over > 30) {
document.getElementById("shipping").style.color = "red";
return true;
} else if(over>0) {
document.getElementById("shipping").style.color = "black";
return true;
}else{
document.getElementById("shipping").style.color = "black";
return false;
}
}
}
and checkout() as
function checkOut() {
if (total()) {
if (((document.getElementById("shipping").style.color == "red") &&
(document.getElementById("extra").checked))||
(document.getElementById("shipping").style.color != "red")) {
return true;
}
}
return false;
}
Replace
var over = qty1 + qty2 + qty3;
With
var over = parseInt(qty1) + parseInt(qty2) + parseInt(qty3);
There were some minor HTML errors but the real issue is that numeric strings were being concatenated. So, to get the quantity values you need to use parseInt() to extract the integer value so that math is performed instead of string concatenation. Also, it's a little odd that the user has to click the Calculate Button in order to see a total. The button does work correctly, but is this what you really want?
One more thing, as tempting as it may be to directly alter the color of elements with JavaScript, in terms of keeping the code more robust, it is preferable to simply change the class name as the code does in this example since I created two classes in the CSS for this purpose.
The form now submits as long as the checkbox is unchecked and the units do not exceed 30. I changed the method to "post" and adjusted the true/false return statements in checkOut(). Note when data is submitted using the POST method, then no form data appears appended to the URL; for more info see here. I also altered the totals() function so that now it returns a value, namely the total price.
var d = document;
d.g = d.getElementById;
var qty = [0, 0, 0, 0];
var shipping = d.g("shipping");
function realNumber() {
var qtyInvalid = [0, 0, 0, 0];
for (let i = 1, max = qtyInvalid.length; i < max; i++) {
qtyInvalid[i] = (isNaN(qty[i]) || qty[i] < 0);
}
if (qtyInvalid[1] || qtyInvalid[2] || qtyInvalid[3]) {
console.log("The quantity given is not a real number or is a negative number!");
return false;
}
return true;
}
function total() {
var over = 0;
var price = [0, 0, 0, 0];
for (j = 1, max = price.length; j < max; j++) {
price[j] = d.g("Price" + j + "").value;
qty[j] = d.g("Quantity" + j + "").value;
}
var totals = 0;
var yes = 0;
const radix = 10;
for (q = 1, max = qty.length; q < max; q++) {
over += parseInt(qty[q], radix)
}
//console.log(over);
if (!realNumber()) {
return false;
}
for (let k = 1, max2 = price.length; k < max2; k++) {
totals += (price[k] * qty[k]);
}
yes = (totals).toFixed(2);
d.g("ProductTotal").innerHTML = "$" + yes;
shipping.className = (over > 30) ? "red" : "black";
return totals;
} // end total
function checkOut() {
var retval = false;
var shippingIsRed = (shipping.className == "red");
var extraChecked = d.g("extra").checked;
if ( total() ) {
retval = (!shippingIsRed && !extraChecked)? true : false;
}
return retval;
} //end checkout

I also removed some unnecessary repetitive code that fetches the quantity values, taking advantage of JavaScript closures and for-loops.

Clone a row in an HTML table and call JavaScript function with the new row

I have a table which has one row in which I multiply two fields, namely quantity and rate/quantity, to get the product total. I have provided a button to add a new row which basically clones the 1st row. Now I want the cloned row to also have the same product as the 1st row. I have tried the following code:
<!DOCTYPE html>
<html>
<h3 align="center">K J Somaiya College Of Engineering, Vidyavihar, Mumbai-400 077</h3>
<h3 align="center">Department Of Information Technology</h3>
<body>
<script>
function WO1() {
var qty = document.getElementById('qty').value;
var price = document.getElementById('price').value;
answer = (Number(qty) * Number(price)).toFixed(2);
document.getElementById('totalprice').value = answer;
}
function WO2() {
var qty = document.getElementById('qty1').value;
var price = document.getElementById('price1').value;
answer = (Number(qty) * Number(price)).toFixed(2);
document.getElementById('totalprice1').value = answer;
}
function WO3() {
var qty = document.getElementById('qty2').value;
var price = document.getElementById('price2').value;
answer = (Number(qty) * Number(price)).toFixed(2);
document.getElementById('totalprice2').value = answer;
}
</script>

{
var x=document.getElementById("floor").value;
if (x==null || x=="")

alert("Floor must be entered");

Not a perfect solution to your problem but a bit closer Working Fiddle
Done using jQuery
$(document).on('change','input', function () {
var id = $(this).attr('id').split("-");
var answer = (Number($('#qty-' + id[1]).val()) * Number($('#price-' + id[1]).val())).toFixed(2);
$('#totalprice-' + id[1]).val(answer);
});
