hi, i have a html form and i have three text boxes named
Max Accessories:
Accessory SKU:
Accessory CPC ID:

and i want a javascript functionality like, if the user enters in the max accessories text box value as 1, then the below two text boxes should update like automatically like below,



AcceSsory 1 SKU
ACCESSORY 1 CPC ID

SIMILARLY if user enters Max accessories value as 2 in the text box,
then the below two text boxes should update like automatically like below
AcceSsory 1 SKU
ACCESSORY 1 CPC ID
AcceSsory 2 SKU
ACCESSORY 2 CPC ID

onchange of the key, for accessory it should call some function in the same page and dynamically update.

can any one please provide, a solution for this , thanks.

Hey guys! I have this website mmosaga.com and in need of some help to fix my BG. Im trying to get my BG to rescale to various of monitor sizes. My monitor width is 1440 and my BG images are Width: 1566 Height:768.

I want that position to show up on all the other browsers including IE.

Here the code I use

PHP Code:

Im having problems with the following code and not sure why it only seems to be a problem when i call for the amount1 variable in the discountedPriceString variable it returns as undefined. but if i just request amount1 in the alert it works fine. Could someone just explain where i have gone wrong

Thanks

Code:

<script>
DISCOUNT_RATE = 0.25;

var price = parseFloat(prompt('Enter the normal price','0.00'));
var discountedPriceString = 'The sale price is $' +amount1 ;
var amount1 = '';

// Apply the discount to the price
discount1 = price * DISCOUNT_RATE;
amount1 = price - discount1 

// Add the new price to the string using toFixed()
amount1 = (amount1.toFixed(2));
alert(discountedPriceString);

</script>

Im writing this code for a gas station program. I have been writing and improving my code for about 3 weeks now and its quite long. I have about classes , customer class, office class and a gas pumps classes. I need help on how to get started on finding the total output at the end of the day. Conceptually i know what i have to do but I don't know where to begin writing the code. I think each time there is a new customer i should add the amount of fuel purchased to a new total fuel purchases variable in the gas pump class. If any one could give me some advice or tips on my theory it would be great ! Should I create a method or can i be done without one.
Code:

import java.util.Random;
import java.util.Scanner;
public class Customer
{
	private String carTag;
	private double gasPurchased;
	private int gasType;
	
	public Customer ()
	{
		Random gen = new Random ( );
		carTag = "";
		for (int i = 1; i <= 6; i++)
		{
			
			//a random number between 48 and 90
			int code = gen.nextInt (43)+ 48;
			if ((code <= 64) && (code >= 58))
			{
				i--;
				continue;
			}
			
			carTag += ((char)(code));
			
		}
		
		System.out.println ("a car arrives; tag number:" + carTag);
		
	}
	
	public int getGasType ()
	{
		Scanner inputDevice = new Scanner (System.in);
		//1:regular, 2:plus, 3:premium
		System.out.println ("enter type of gas to buy " + 
				"(1:regular, 2:plus, 3:premium): ");
		gasType = inputDevice.nextInt ();
		return gasType;
		
	}
	
	public double getGasPurchased ()
	{
		Random gen = new Random ();
		gasPurchased = gen.nextDouble ()* 50;
		return gasPurchased;
	}

I'm not really good with javascript and need help with a problem. I'm creating a pop-up window that goes to another site but sends the url it's coming from in the url it's going to.

Ok here's what I have if that's confusing.
Code:

<head>
<script type="text/javascript">
function popupwin(url) 
{
 var width  = 650;
 var height = 250;
 var left   = (screen.width  - width)/2;
 var top    = (screen.height - height)/2;
 var params = 'width='+width+', height='+height;
 params += ', top='+top+', left='+left;
 params += ', scrollbars=1';
 newwin=window.open(url,'popupwin', params);
 if (window.focus) {newwin.focus()}
 return false;
}
</script>
</head>
<body>
<a href="javascript: void(0)" onClick="popupwin('http://example.com/check.php?id=http://$_SERVER[SERVER_NAME]$_SERVER[REQUEST_URI]'); return false;">Centered popup window</a>

Now that above code works fine in most cases and on most sites. The problem is that one forum I've tried it on has a seo mod which means the php comand $_SERVER[REQUEST_URI] isn't the same that's in the address bar. Instead of showing Code:

http://sitename.com/forum/main-forum/1-test-post-title-some-list.html

it's showing Code:

http://sitename.com/forum/showthread.php?p=1

After Googling I know that document.write(location.href) will give me the exact url of the seo url as it appears in the address bar which is what I want. Can anyone show me how to combine document.write(location.href) with my code. I know it's probably easy for most but I only really know basic html and php and I'm only new to javascript.

Thanks in advance.
