Currency Calculator Problem	View Content

Hey I've been working on my Spanish Clubs' website over the summer and I need some help when making this converter. I want to make it so when someone chooses a different country, it will change the answeres and do the equation in the text boxes and also if they change the numbers manually they will also do the equation.

I've tried it out and it's making me go mad. PLEASE HELP!

Here is the javascript code I made:

Code:

function calculatecountry()
{
	var country = calculate.countrys.options[calculate.countrys.selectedIndex].text;
	
	//===============================COUNTRIES====================================
if (countrys=="--Country--")
{
	var usd1 = 0;
	var other1 = 0;
}
if (countrys=="Argentina")
{
	var usd1 = 0.2553;
	var other1 = 1;
}
if (countrys=="Bolivia")
{
	var usd1 = 0.14245;
	var other1 = 1;
}
if (countrys=="Chile")
{
	var usd1 = 0.0018;
	var other1 = 1;
}
	//================================EQUATIONS=====================================
	
	var c1 = calculate.other.value;
	var c2 = calculate.usd.value;
	
	var ans1 = c1 * other1;
	var ans2 = c2 * usd1;
	
	calculate.usd.value = ans1;
	calculate.other.value = ans2;
}

Here is the form code:

Code:

     
<html><head><title></title>

<script type="text/javascript" src="js_money_calc.js"></script>

</head><body>

 Converter
		<form name="calculate">
          <select name="countrys" onChange="calculatecountry()">
          <option selected>--Country--</option>
          <option>Argentina</option>
          <option>Bolivia</option>
          <option>Chile</option>
          </select><p>
            <input type="text" name="usd" onKeyUp="calculatecountry()" /> = <input type="text" name="other" onKeyUp="calculatecountry()" /></p>
          </form>

</body></html>

Hi, I am new to Javascript and I am having a problem with this calculator I am building. The purpose is to see if you will be able to go to prom. In a form you input 4 pieces of info. (1)How much money the ticket costs. (2)How much money your tuxedo costs. (3)How much money the dinner costs. (4)How much money you have. I have the calculator set up, and it is supposed to add together the ticket cost, tuxedo cost, and dinner cost, and subtract it from how much money you have. I finished the code, and I am getting no error at the bottom of the screen, but the calculator doesn't work. So, I guess it is a logic error. Here is the code and a link to the page:

function prom(myform) {
var ticket=document.Calculator.ticket.value
var ticket=parseInt(ticket,10)
if (isNaN(ticket)) {
alert("Enter a number for the Ticket Cost.")
document.Calculator.ticket.value=""
document.Calculator.ticket.focus()

} else {

var tuxedo=document.Calculator.tuxedo.value
var tuxedo=parseInt(tuxedo,10)
if (isNaN(tuxedo)) {
alert("Enter a number for the Tuxedo Cost.")
document.Calculator.tuxedo.value=""
document.Calculator.tuxedo.focus()

} else {

var dinner=document.Calculator.dinner.value
var dinner=parseInt(dinner,10)

Grade Calculator Problem

View Content

I have this project i have to complete for class, that i cant figure out. this is what the project says:

Prompt the user for the grades of 10 students with one prompt for
each grade with the prompting text being: "Enter grade between 1 and
10 for student n:" where n varies from 1 to 10. If the grade input is
not between 1 and 10, please prompt again for the grade.

Once the user is done, it prints a report telling you the grade of
each individual student and the average of the ten grades. The
individual student grade should be in different lines with the text
"Grade for student n is x". The average should also be in a different
line with the text "Average grade is y". The average grade should not
be rounded off.

my problem is i cant figure out how to write each individual grade (from 1 through 10), and display it on the page.

i have this code from a similar project, i tried to ammend it for this code but i always end up ruining it
any tips on how to display each grade (1-10)?
or how to verify that the user only enters grades between 1 and 10

Code:

can you guys see whats the problem?

Heres the java script

eg. when you write 86708 kills and 53240 death

1,64 = 389
1,70 = 3582

Calculator Calculation Problem

I am a student trying to complete this assignment. Any assistance you can give me is greatly appreciated. My code is inserted below.

This is calculator program that I have gotten stuck on. Here is where I think I am at:

The program is now taking the 1st number entered displaying it and storing it in the variable "memory".
Operation (+,-,*,/) is added to the memory in function action1()
but then when the second number is entered it replaces memory with the second number. How can I get the variable memory to the whole string of 1st number,action, 2nd number?

Also once I do get that working correctly:
Wouldn't eval(document.calculator.display.value= memory) in my HTML for the "=" give me the calculation. ( if I could figure out how to have memory store the 1st number and action1 and 2nd number all together)
Or would eval(document.calculator.display.value) do it for me.

Hello
I have this script
Code:

/* This script and many more are available free online at

function currencyFormat(fld, milSep, decSep, e) {
  var sep = 0;

  var i = j = 0;
  var len = len2 = 0;
  var strCheck = '0123456789';
  var aux = aux2 = '';
  var whichCode = (window.Event) ? e.which : e.keyCode;

  if (whichCode == 13) return true;  // Enter
  if (whichCode == 8) return true;  // Delete
  key = String.fromCharCode(whichCode);  // Get key value from key code
  if (strCheck.indexOf(key) == -1) return false;  // Not a valid key
  len = fld.value.length;

    fld.value += aux2.charAt(i);
    fld.value += decSep + aux.substr(len - 2, len);
  }
  return false;
}

and I call it like that:
onKeyPress="return(currencyFormat(this,',',',',event))"

the ouput is:
100,000.00

How can I get rid of of the last 2 ziros after the last dot

I need this kind of output

1,000
10,000
100,000
1,000,000

Hi I have the following currency converter code which works fine, but I need to make it possible for someone else to edit the euro price using a visual editor such as contribute.

Code:

<script language='javascript'>

document.write('(&pound;' + Math.round(price / exchRate) + ')');
}
</script>

</head>
<body>

<strong>&euro;1999</strong> <script type="text/javascript">getUKP('1999');</script>

</body>
</html>

This code requires someone to change the figure in the javascript as well as the html. I guess I need to somehow automatically pick up the numeric characters only from the html which appear on the same line of code... or perhaps there's an easier way.?

Any help would be much appreciated.

Thanks

... or at least adding the commas? I need to format this number as currency. It is within the "flot" code, which is a charting framwork. I dont know anything about javascript at all so bear with me.

Here is part of the code, the piece in red calls for the number. This is what I need displayed with commas, so its easy to read. I have found a few examples on the web but I have no idea how to apply them to this code. Can anyone help?

Code:

var previousPoint = null;
$("#placeholder").bind("plothover", function (event, pos, item) {
$("#x").text(pos.x.toFixed(2));
$("#y").text(pos.y.toFixed(2));
 
if ($("#enableTooltip:checked").length > 0) {

if (previousPoint != item.datapoint) {
previousPoint = item.datapoint;

var x = item.datapoint[0].toFixed(2),
y = item.datapoint[1].toFixed(2);

Automatical Currency Conversion

Similar Tutorials

View Content

Dear All,
On my HTML page, I am trying to use as a snippet the script for automatic currency conversion. It is well known that exchange rates between currency are being changed very often (most of times even daily) and I don't want to republish either page with script or entire website every time the exchange rate changes. For website design I am using xsitepro software because I don't know programming.
So what I would like to have on specific page of website is something similar to table (if anyone has any better recommendation than using a table, please share). In this table I would like to state prices of my services. Primary currency is only one. So in this column, the numbers shouldn't be changed unless I want to change the prices (and of course therefore republish the website, no need to republish sitemap). In the rest of the columns the numbers should be changed immediately, without needing to republish anything (thats the point of the script) and also rounded to each 5. What I mean with ''each 5'' is shown on few of the following random chosen examples (1500):

1500.03 is rounded to 1500
1500.30 is rounded to 1500
1500.50 is rounded to 1500
1502.49 is rounded to 1500
1502.50 is rounded to 1505 (!)
1504.99 is rounded to 1505
1505.01 is rounded to 1505
1507.49 is rounded to 1505
1507.50 is rounded to 1510

and so on. Idea is to prevent from getting coins. So the break point is on 2.50, 7.50, 12.50, 17.50, 22.50, 27.50 and so on. Not sure how to mathematically describe this. Hopefully I was understandable.

I want to have in the columns only the currencies that I am willing to accept if potential client cannot change the currency to my primary one (given in second most left column) in his local exchange office. But I repeat that what Im trying to do is having automatically and immediately updated numerical values on particular HTML page based on most recent exchange rates (of course trustful source is needed).
Since I don't know programming, I did some research on google and discovered this:

http://coinmill.com/webmaster_options.html

The downer script on the right side looks ok but its not even close to what I need due to five reasons:
- it is being converted outside the table
- with such way i cannot clearly show which currency is primary (prefered) one
- conversion is being done to only one other currency at the same time
- no rounding to ''each 5''
- unknown source (and therefore untrustful one) of updating most recent exchange rates

Table such as this one:

http://www.x-rates.com/

looks great but still not meeting my requirements. I would like to replace flags in the left column with ''service 1'', ''service 2'', ''product 1'' etc. Also I have no idea how rounding could be done.
So at the end I would end up with something like (here Im showing only two ''still willing to accept'' currencies just to show an example):

Currency:Euro Currency:American Dollar Currency:Japanese Yen
Service1 500 670 51535
Service2 400 535 41228
Service3 200 265 20614

Top left corner as it is on x-rates.com would be even better.

note: when I previewed my post before submitting, I noticed that the forum doesn't let me make so much spaces but I think those numbers are still understandable where do they belong.

Any help would be muuuuuch appricated

A Simple Currency Convertor

Hi,
I'm really stupid and haven't been working with javascript long, so forgive my incompetence. I need to create a simple currency convertor. Not with live rates or anything like that.
It needs to allow a user to input a dollar amount, add a bank fee to that and convert the amount into one of six currencies.

here is my code
Code:

<html>
<head>
<script type="text/javascript">
<!--
var Amount=document.getElementById('amount');
var Fees=document.getElementById('bankComm');
var Total=document.getElementById('ausTotal');
var Currency=document.getElementById('currency');
var Converted=document.getElementById('converted');
var Choice=document.getElementById('choice');
function fees()
{
var Amount=document.getElementById('amount');
var Fees=document.getElementById('bankComm');
	if (Amount.value>=1&&Amount.value<5001)
	{
	Fees.value=20
	}
	if (Amount.value>=5001&&Amount.value<10001)
	{
	Fees.value=30
	}
	if (Amount.value>=10001)
	{
	Fees.value=40
	}
}
function addFees()
{
var Amount=document.getElementById('amount');
var Fees=document.getElementById('bankComm');
var Total=document.getElementById('ausTotal');
	
Total.value=Fees.value+Amount.value
}
function convert()
{
var Amount=document.getElementById('amount');
var Currency=document.getElementById('currency');
var Converted=document.getElementById('converted');
var Choice=document.getElementById('choice');
var US=0.91810;
var UK=0.60285;
var HK=7.12812;
var SNG=1.26784;
var JY=84.2563;
var NZ=1.29565;
	switch(document.convertor.currency.value)
	{
	case:"US Dollars"

</html>

I've tried using getElementbyId and using the names, as far as I can tell, it's sytactically correct, but It doesn't seem to work no matter what I do.

I have a headache, actually I have two.
If anyone can help me, I'd be extremely grateful.

Hi,

I need to create a currency converter using a drop down menu. Firstly i needed to do a regular expressions check to make sure only numerics are entered and I got that. The one thing im pretty confused on is how to do the calculations in the actual function. Ive popped the code below, and if anyone could give me some hints on how to get the data from the drop down menu and calculate it properly that would be awesome. Thanks.
-oh and i know all my coding is here but i think its relevent that you can view it all.
Code:

<html>
<head>
<style type ="text/css">
 @import url(style.css);
</style>

<script type="text/javascript">
  function convert()
  {
    var OK = true;
	var inDollar= document.getElementById('dollars').value;
	var regex= /^\d{1,}$/;
	if (!regex.test(inDollar))
	{
	  OK=false;
	  alert('Australian Dollars must be entered as numeric with no decimal places');
	}
	return OK;
	
	var rate= country.conversion.value;
	
	if (document.getElementByID('conversion').selectedIndex == 0)
	{
	 var rate= country.conversion.value;
	 var convert = inDollar*rate;
	 alert('$'+inDollar+' converts to'+rate+' US Dollars');
	}
	if (document.getElementByID('conversion').selectedIndex == 1)
	{
	 var rate= country.conversion.value;
	 var convert = inDollar*rate;
     alert('$'+inDollar+' converts to'+rate+' Euro');
	}
	if (document.getElementByID('conversion').selectedIndex == 2)

	 var rate= country.conversion.value;
	 var convert = inDollar*rate;
     alert('$'+inDollar+' converts to'+rate+' Yuan');
	}

	{
	 var rate= country.conversion.value;
	 var convert = inDollar*rate;

if the code was like

var="10000000" <-the number I dynamically pass in

(previously posted in the wrong forum and re-posted in this one)
Hi there, I have scoured the internet looking for the right code but to no avail. I have gotten as far as totaling up my form but now want to format the amounts and total as currency and also want the values that = 0 to just be blank. I have tried to use the code from other solutions (posted on the net) but I just think it is over my head because I cant figure it out. I thought I was close a few times but wasn't able to bring it on home. One of my issues is using somebody's code and not knowing where in my code to place it. http://www.whackyweedremoval.com/wwr-invoice.html

I have tried exhaustively to solve on my own but there is a point.

Javascript - Text Box Currency Format

Similar Tutorials

View Content

Hello,

Firstly - relatively new to javascript.

I have seen many examples of code that will return a passed value in a currency format - however I have a sales form that is calculating values via a function in the text boxes I want formatted with a currency ($) symbol. The function that is called is not passing any values, and returning a calculation of the form subtotals per item, and then total sales figure.

Can anybody give me any hints on format these cells to a currency value?

I can give examples of how my code is currently if required.

Thanks in advance
