JavaScript - How To Split On Decimal Code Points Or Equivalent Format

Hello:

I have this js function:

Code:

<script type="text/javascript">
function updatesum() {
document.PaymentForm.newbalance.value = (document.PaymentForm.balance.value -0) - (document.PaymentForm.paymentamount.value -0);
}
</script>

I want to round the value of Code:

document.PaymentForm.newbalance.value

to two decimal points.

May I request some assistance!

Hi guys.. I really need a bit of help.. is anyone looking at this good with JS?

I have a php form validation script but i think its a bit slow and would rather a JS script instead...

here is what i have in php..

PHP Code:
    <?php
  if(isset($_POST['submit']))
      {
          $firstName = $_POST['firstName'];
          $lastName = $_POST['lastName'];
          $email = $_POST['email'];
          $mobile = $_POST['mobile'];
          $comments = $_POST['comments'];
         
          $errors = array();
          
        function display_errors($error)
          {
          echo "<p class=\"formMessage\">";
          
          
            echo $error[0];
            
            echo "</p>";
          }  
          
         function validateNames($names) 
        {
        return(strlen($names) < 3);
        } 
        
        function validateEmail($strValue) 
        {
           $strPattern = '/([A-Z0-9._%+-]+@(?:[A-Z0-9-]+\.)+[A-Z]{2,4})/sim';

        } 
        
        function validateMobile($strValue) 
        {

           return(preg_match($strPattern,$strValue));
        }

However, what this piece of code does is that, every radio button gets only 1 point. What I intended is that every subsequent radio button in each <td> garners incremental points by 1.

Eg: Q1, 1st radio button gets 0pt, 2nd radio button gets 1pt, 3rd radio button gets 2pt.

Does anyone have any idea how to implement that, all help are greatly appreciated!

This post will contain a few guidelines for what you can do to get better help from us. Let's start with the obvious ones:

- Use regular language. A spelling mistake or two isn't anything I'd complain about, but 1337-speak, all-lower-case-with-no-punctuation or huge amounts of run-in text in a single paragraph doesn't make it easier for us to help you.

- Be verbose. We can't look in our crystal bowl and see the problem you have, so describe it in as much detail as possible.

- Cut-and-paste the problem code. Don't retype it into the post, do a cut-and-paste of the actual production code. It's hard to debug code if we can't see it, and this way you make sure any spelling errors or such are caught and no new ones are introduced.

- Post code within code tags, like this [code]your code here[/code]. This will display like so: Code:

alert("This is some JavaScript code!")

- Please, post the relevant code. If the code is large and complex, give us a link so we can see it in action, and just post snippets of it on the boards.

- If the code is on an intranet or otherwise is not openly accessible, put it somewhere where we can access it.

- Tell us any error messages from the JavaScript console in Firefox or Opera. (If you haven't tested it in those browsers, please do!)

- If the code has both HTML/XML and JavaScript components, please show us both and not just part of it.

- If the code has frames, iframes, objects, embeds, popups, XMLHttpRequest or similar components, tell us if you are trying it locally or from a server, and if the code is on the same or different servers.

- We don't want to see the server side code in the form of PHP, PERL, ASP, JSP, ColdFusion or any other server side format. Show us the same code you send the browser. That is, show us the generated code, after the server has done it's thing. Generally, this is the code you see on a view-source in the browser, and specifically NOT the .php or .asp (or whatever) source code.

this code is formatting the price like that 500 000 but i need to price format like this 500.000 so i need dot instead space
