Javascipt replacing exact numbers in an array

am trying to replace numbers in an array but am facing an issue which am not really able to correctly manage regarding how to correctly target the just one data I really have to change.
I'll make an example to have more accuracy on describing it.
Imagine my data array look like that:
["data", "phone numbers", "address"]
I can change numbers via following script but my first problem is that it makes no differences between the number it find in columns, for example "phone numbers" from "address" (at the moment am not using it, but should I include a ZIP code in the address it would be really be a problem)
Beside, my second and current problem with my script, is that obviosuly in the same "phone numnbers" a number may appear more times while I'd like to affect only the first block of the data - let's say to add/remove the country code (or even replace it with it's country vexillum) which I normally have like that "+1 0000000000" or "+54 0000000000"
So if a number is for example located in EU it really make this script useless: Spain is using "+34" while France "+33" and it wouldn't succeded in any case becouse it recognize only "+3" for both.
I've found some one else already facing this problems which seems to solved it wrapping the values inside a buondaries - for example like that "\b"constant"\b" - but either am wronging syntax either it does not really apply to my case. Others suggest to use forEach or Array.prototype.every which I failed to understand how to apply at this case.
Should you have other ideas about that am open to try it!
function phoneUPDATES(val)
{
var i= 0;
var array3 = val.value.split("\n");
for ( i = 0; i < array3.length; ++i) {
array3[i] = "+" + array3[i];
}
var arrayLINES = array3.join("\n");
const zero = "0";
const replaceZERO = "0";
const one = "1";
const replaceONE = "1";
const result0 = arrayLINES.replaceAll(zero, replaceZERO);
const result1 = result0.replaceAll(one, replaceONE);
const result2 = result1.replaceAll(two, replaceTWO);
const result3 = result2.replaceAll(thre, replaceTHREE);
const result4 = result3.replaceAll(four, replaceFOUR);
const result5 = result4.replaceAll(five, replaceFIVE);
const result6 = result5.replaceAll(six, replaceSIX);
const result7 = result6.replaceAll(seven, replaceSEVEN);
const result8 = result7.replaceAll(eight, replaceEIGHT);
const result9 = result8.replaceAll(nine, replaceNINE);
const result10 = result9.replaceAll(ten, replaceTEN);
const result11 = result10.replaceAll(eleven, replaceELEVEN);

Why not use a regex replace, you could do something like /(\+\d+ )/g which will find a + followed by one or more digits followed by a space, and then you can strip out the match:
const phoneNumbers = [, "+54 9876543210"]
console.log(phoneNumbers.map((num) => num.replaceAll(/(\+\d+ )/g, '')))
If you need to only target the second element in an array, i'd imagine your data looks like
const data = [["data", "+1 1234567890, +1 5555555555", "address"], ["data", "+11 111111111, +23 23232323", "address"]];
console.log(data.map((el) => {
el[1] = el[1].replaceAll(/(\+\d+ )/g, '');
return el;
}))

ok, this almost is cheating but I really didn't thought it before and, by the way does, not even actually solve the problems but jsut seems to work around it.
If I call the replacemente in decreasing order that problem just does not show up becouse condition of replacement involving higher numbers are matched before the smaller one.
but should some one suggest a complete "true code comply" solution is wellcome

d3.format thousand separator on variables?

Hello I'm yet again stuck on d3...
I'd like to know how to use a thousand seperator on a variable all the examples I've managed to find seem to be on static data.
This is what I've tried so far:
d3.csv("OrderValueToday.csv", function(obj) {
var text = 'Today = £';
var totalSales = text + d3.format(",") + obj[0].Today;
svgLabel = d3.select("#label").append("h2")
.text (totalSales);
});
However it just outputs a load a stuff on the webpage this is it:
Today = £function (n){var e=d;if(m&&n%1)return"";var u=0>n||0===n&&0>1/n?(n=-n,"-"):a; if(0>p){var c=Zo.formatPrefix(n,h);n=c.scale(n),e=c.symbol+d}else n*=p;n=g(n,h);var x=n.lastIndexOf("."),M=0>x?n:n.substring(0,x),_=0>x?"":t+n.substring(x+1);!s&&f&&(M=i(M));var b=v.length+M.length+_.length+(y?0:u.length),w=l>b?new Array(b=l-b+1).join(r):"";return y&&(M=i(w+M)),u+=v,n=M+_,("<"===o?u+n+w:">"===o?w+u+n:"^"===o?w.substring(0,b>>=1)+u+n+w.substring(b):u+(y?n:w+n))+e}20000
So all I want is to be able to make the totalSales value have thousand separators so like 20,000 everything else I've tried doesnt do anything. I've read this https://github.com/mbostock/d3/wiki/Formatting but didnt see what I could do for my scenario.
Any help would be greatly appreciated. Cheers

Specifying a d3.format returns a formatting function, which you must then call as a function, passing in the number to be formatted as an argument:
var myNumber = 22400;
d3.format(',')(myNumber); // returns '22,400'
Sometimes you will see a format function stored as a variable like this:
var commaFormat = d3.format(',');
commaFormat(1234567); // returns '1,234,567'
In your case, you could do the following:
var totalSales = text + d3.format(',')(obj[0].Today);

Finding the difference between two fields using JavaScript in iText

I would like to find difference between two fields using JavaScript in iText.
I am able to find the sum of them using below code:
PdfStamper stamperResult = new PdfStamper(readersectionResult, new FileOutputStream(RESULT_NEW));
stamperResult .addJavaScript("var nameField = this.getField(\"total\");"+ "nameField.setAction(\"Calculate\",'AFSimple_Calculate(\"SUM\",\"total1\", \"total2\")')");
Is there any way to find the difference using 'AFSimple_Calculate' similar to what I did in the above code snippet?
Thanks for editing! I tried your suggestion but it does not seem to work for some reason.
stamperResult.addJavaScript(" var total1 = this.getField(\"value1\"); var total2 = this.getField (\"value2\"); var subtr = this.getField(\"total\"); subtr.value = total1.value - total2.value;");
I separated newlines by spaces and added right escape characters.
I was also thinking of using a different logic for subtraction using AF methods : like this
stamperResult.addJavaScript("var nameField = this.getField(\"total\");"+ "nameField.setAction(\"Calculate\",'AFSimple_Calculate(\"SUM\",\"total1\", \"-total2\")')");
In the above code I was trying to add -(negative value) to total 2 so that it will be subtracted from total1 though the AF method is still 'SUM'.
But that does not work.
The below simple code seem to work :
stamperResult.addJavaScript("var nameField = this.getField('total');" +
"nameField.setAction('Calculate'," +
"'subtract()');" +
"" +"function subtract(){this.getField('total').value
= (this.getField('total_1').value -this.getField('total_2').value); }");

I updated your question because it contained many spelling errors. I didn't edit the code snippet because I don't know what the original code snippet is like. In any case: I think something went wrong during the copy/paste process, as I don't think your code snippet compiles in its current state.
In any case: as far as I know the AF-methods (the AF stands for Adobe Forms) may not be present in every viewer, and as far as I know Adobe didn't implement a way to subtract values from each other in the AFSimple_Calculate method.
For these two reasons, you may prefer regular JavaScript instead of using a pre-canned function that may or may not be pre-canned.
This regular JavaScript may look like this:
var total1 = this.getField("total1");
var total2 = this.getField("total2");
var subtr = this.getField("difference");
subtr.value = total1.value - total2.value;
I'm not sure if that answers your question. Maybe you just want:
var total1 = this.getField("total1");
var total2 = this.getField("total2");
var namefield = total1.value - total2.value;
You can put these lines inside a String using the right escape characters and replacing the newlines by spaces or newline characters.
Of course, you need to trigger this code somewhere. Below you'll find an example that puts the negative value of the content of a value1 field into a value2 field.
public static void main(String[] args) throws IOException, DocumentException {
Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("js.pdf"));
document.open();
writer.addJavaScript("function makeNegative() { this.getField('value2').value = -(this.getField('value1').value); } ");
Rectangle rect1 = new Rectangle(40, 740, 200, 756);
TextField value = new TextField(writer, rect1, "value1");
value.setBorderColor(GrayColor.GRAYBLACK);
value.setBorderWidth(0.5f);
PdfFormField field = value.getTextField();
field.setAdditionalActions(PdfName.BL, PdfAction.javaScript("makeNegative();", writer));
writer.addAnnotation(field);
Rectangle rect2 = new Rectangle(40, 710, 200, 726);
TextField neg = new TextField(writer, rect2, "value2");
neg.setBorderColor(GrayColor.GRAYBLACK);
neg.setBorderWidth(0.5f);
writer.addAnnotation(neg.getTextField());
document.close();
}
Note that I used a Blur action. This means the method will be triggered as soon as you select another field after filling out the value1 field.

Variable Returning NaN Value - Cannot find out why

I am having to pickup from where someone in the business left off many years ago with an aging texting system.
It was built using ASP classic and sends a string to an API that then texts out, all this is neither here nor there. The problem i have is no JS experience, I am am a SQL Developer and did a little bit of ASP Classic (VBScript) years ago.
This piece of JScript picks up information from several form boxes and then places them in a string which is then passed to variable on a processing page to text out. The fields 'QValue, Indemnity and Excess' are all numeric. The Cover is text and it is replacing the cover text with 'NaN' now I understand this is for 'Not A Number' well that is exactly what it is, not a number but I want the text string.
Here is the snippet of code in question:
<script type="text/javascript">
function changeMessageText()
{
var messagetxt = document.getElementById('message').value
var QValue = document.getElementById('QValue').value
var Cover = document.getElementById('Cover').value
var Excess = document.getElementById('Excess').value
var Indem = document.getElementById('Indemnity').value
var messagetxt=messagetxt.replace("[QValue]", + QValue)
var messagetxt=messagetxt.replace("[Cover]", + Cover2)
var messagetxt=messagetxt.replace("[Excess]", + Excess)
var messagetxt=messagetxt.replace("[Indem]", + Indem)
document.getElementById('messageText').innerHTML = messagetxt;
}
</script>
Cheers.

When you do string.replace(searchvalue,newvalue), there is no need of + before the newValue
var messagetxt=messagetxt.replace("[QValue]", QValue)
//cover or cover2 whichever appropriate
var messagetxt=messagetxt.replace("[Cover]", Cover)
var messagetxt=messagetxt.replace("[Excess]", Excess)
var messagetxt=messagetxt.replace("[Indem]", Indem)

Is it normal that you use Cover2 in the replace where you read the input value and store it in the Cover variable ?
Those are two different variables and from the code you provided, we can only assume that Cover2 is initialized with NaN (which might not be the case, it can be copy/paste error).

Here is how you do it:
var messagetxt = document.getElementById('message').value;
var QValue = document.getElementById('QValue').value
var Cover = document.getElementById('Cover').value
var messagetxt=messagetxt.replace("[QValue]", QValue)
var messagetxt=messagetxt.replace("[Cover]", Cover)
document.getElementById('messagetxt').innerHTML = messagetxt;

Javascript Regular Expression to attempt to split name into Title/First Name(s)/Last Name

I want to try and detect the different parts of a person's name in Javascript, and cut them out so that I can pass them onto something else.
Names can appear in any format - for example:-
miss victoria m j laing
Miss Victoria C J Long
Bob Smith
Fred
Mr Davis
I want to try and write something simple, that'll do it's best to guess these and get them right 80% of the time or so (We have some extremely dodgy data)
I'm thinking of something along the lines of using a regex to check whether it has a prefix, then branch off to two places as to whether it has
/^(Dr|Mr|Mrs|Miss|Master|etc).? /
And then cutting the rest of it out using something like
/(\w+ )+(\w+)/
To match last name and other names. Though, I'm unsure on my greedy/ungreedy options here, and whether I can do soemthing to shortcut having all the different paths that might be available. Basically, hoping to find something simple, that does the job in a nice way.
It's also got to be written in Javascript, due to the limitations of the ETL tool I'm using.

Why not split() and just check the resulting parts:
// Split on each space character
var name = "Miss Victoria C J Long".split(" ");
// Check the first part for a title/prefix
if (/^(?:Dr|Mr|Mrs|Miss|Master|etc)\.?$/.test(name[0])) {
name.shift();
}
// Now you can access each part of the name as an array
console.log(name);
//-> Victoria,C,J,Long
Working Demo: http://jsfiddle.net/AndyE/p9ra4/
Of course, this won't work around those other issues people have mentioned in the comments, but you'd struggle on those issues even more with a single regex.

var title = '';
var first_name = '';
var last_name = '';
var has_title = false;
if (name != null)
{
var new_name = name.split(" ");
// Check the first part for a title/prefix
if (/^(?:Dr|Mr|Mrs|Miss|Master)\.?$/i.test(new_name[0]))
{
title = new_name.shift();
has_title = true;
}
if (new_name.length > 1)
{
last_name = new_name.pop();
first_name = new_name.join(" ");
}
else if(has_title)
{
last_name = new_name.pop();
}
else
{
first_name = new_name.pop();
}
}
