## Calculate Subtotal - Tax And Total Using Multiple Text Boxes

Apr 15, 2009

I am trying to simulate a simple checkout page where a user inputs the quantity of merchandise that they want in multiple text boxes. When they click "calculate" it calculates the subtotal, tax, and total. As it stands my calculate function works if I do quantity * price for each text box and then add together. I would have to do this 9 times! :eek: I would like to use an array but I am not exactly sure how to use it to do calculations. I know I need a loop (which I have written) and an array (which is written also).

## How To Calculate / Add Values To Total Amount

Oct 14, 2011

I followed a tutorial online on how to use Javascript to calculate total price. Everything works fine, when all the dropdown select value has it's own value and does not correspond to each other.

Eg :
Cake Type : Round \$4.00
Cake Color : Red \$3.00
Cake Filling : Raspberry \$4.00
So total is \$11.00

The problem comes when you want to add Cake Layers and the price of Cake Color changes based on No of Layers - 1 Layer , 2 Layer and so on. E.g.:
Cake Layer : Layer 1 \$5.00 | Layer 2 \$2.50 | Layer 3 \$2.50 (for color Orange)
Cake Layer : Layer 1 \$7.00 | Layer 2 \$4.00 | Layer 3 \$4.00 (for color Red)

Do I have to use if and else conditional statement for every possibility? I am just a beginner. Attached below is the example code I have so far:
var filling_prices= new Array();
filling_prices["None"]=0;
filling_prices["Lemon"]=5;
filling_prices["Custard"]=5;
filling_prices["Fudge"]=7;
filling_prices["Mocha"]=8;
filling_prices["Raspberry"]=10; .....
function getFillingPrice(){

Is there a better way of simplifying this calculation method? How do I change the price of form values based on selected values on previous dropdown.

## Alternatives To Sending The Amount To Paypal?

Mar 29, 2011

I wrote a website in html, which has an ecommerce that sends the purchase to paypal. My client wants to offer a coupon. I found code in javascript that validates the coupon, but I want to be able to tell PayPal the discounted amount as this discount will not apply to all customers. PayPal Merchant Services told me that I can not use a variable in the following line:

<input name="amount" type="hidden" value="132" />

Is there a way I can use Javascript to do the following? At this time, this code doesn't give me an error, but it doesn't send the amount to PayPal either.

<script language="javascript">function validate(text1,text2) {
if (text1 == text2)
{ document.write('<input name="amount" type="hidden" value="0" />')
