if you want to redirect to a page:yourphppage.php if the user pressed ok.

 function show_confirm()
 {
      var r=confirm("Do You Really want to Refund money! Press ok to Continue ");
      if (r==true)
        {
        window.location="yourphppage.php";
        return true;
        }
           else
        {
        alert("You pressed Cancel!");
        }
 }
Answer

If you are looking for page direction:

window.location="index.php";

There are plenty other methods to redirect: http://grizzlyweb.com/webmaster/javascripts/redirection.asp

Place this where you want your redirect to happen:

location.href = "newpage.php";

Then have a look at
http://mootools.net/docs/core/Request/Request
Any of the JS libraries prototype Jquery etc. have a wrapper to make requests and your life easier.
Then just have a button and set its onClick to be the request call to the server and listen for the response.


Some tips you can append data to the request URL to pass your PHP script variables. Checkout

Answer

If you only want to redirect the page to the "refund" page without using AJAX you can do something along the lines of the following:

(assumes $transaction_id variable is the id number you are looking to refund)

HTML Lines:

    <td align="center">
    <input name="Refund" onclick="show_confirm(<?php echo $transaction_id ?>)" type="submit" value="Refund" />
    </td>

Javascript lines:

    function show_confirm(transaction_id) 
    { 
        var r = confirm("Do You Really want to Refund money! Press ok to Continue "); 
        if (r == true)   
        {   
            alert("You pressed OK!");  
            location.href = "refund.php?transaction_id="+transaction_id; 
            return true;   
        } 
        else   
        {   
            alert("You pressed Cancel!");   
        } 
    }
