# Add Two Form Values Together To Get Total?

Apr 4, 2011

I have been working on a calculator that works out the difference between two prices. I have two forms on my page which each generate a total, I want to add those two values together and display them in a third form.

## Calculate 2 Form Values With Price And Sums With Total

Sep 20, 2009

Formfield.anzahl1 = number entered by customer
Formfield.Price1 = Ergebnisfeld1
e.g.
Anzahl1= 1
Price = 270
*if Anzahl1 = 2 then Price = 270*2

I need to do this for two form option. 2nd field would be as follows

Formfield.Anzahl2= number entered by customer
Formfield.Price2 = Ergebnisfeld2
Then Formfield.Total = Ergebnisfeld1 + Ergebnisfeld2

How can I convert these above to javascript?

## Special Values From Drop-down Menu & Total In Simple Form?

May 10, 2011

I have the perfect form for a client - but its missing one thing. She sells hair clips in various colors. A user can select a hair clip color and quantity quite easily (as seen in the code below). My issue is that she wants to be able to give the user a 'special price' based on the quantity ordered by the user. Contrary to simply adding the default price of \$7 over and over again based on the quantity selected.The way I want it to work...

1 clip is \$7
2 clips are \$12
3 clips are \$22
5 clips are....etc.

...however, with the way that the javascript is set up now I'm only able to select one default price. This means that whatever quantity is selected -- it's simply multiplied by the number 7 to provide a total.

1 clip is \$7
2 clips are \$14
3 clips are \$21
5 clips are....etc.[code].....

## "document.getElementById ('total').value = Total;" Not Submitted In Form Post?

Jun 25, 2009

I have a issue with a javascript code that I wrote. This script is a simply for calculating the summation of 2 text input boxes and printing it in another text input box within the form. The entire form is then sent using Form post.The total is written back to the form's total text input box using the code below:

document.getElementById ('total').value = total

This code works perfectly for displaying the values on screen. However, when I send the form (PHP Post), the " total " field is empty. I have searched all over for possible solutions. But no solution yet.

1. document.getElementById ('total').INNERHTML = total .This does not even work on screen and total field is not updated on screen. Needless to say, the PHP Post variable was also empty.

## How To Add Up Two Values For Total Cost

## Total Up Values In Text Boxes

## 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.

## Sum Of Radio Buttons Value - Total Does Not Reflect The Actual Total ?

Sep 2, 2011

I used the sum of check boxes script, altered it for radio buttons and it works... except for one little nit-picking thing.If a user changes their mind and chooses the other radio button in the set, the total does not reflect the actual total unless they click again on an already set radio button on the side they are using.Here's the JS:

Code:
//Adds the sum of all radio buttons for the Home Team (Games Won)
function UpdateCost() {
var sum = 0;[code]......

How can I get this to reflect the actual games won if a user changes a radio button from home team to visiting team? I have a duplicate JS (UpdateCost2) and I have a matched pair of radio buttons for each game. Either you win (get 1) or lose (get 0).

## NaN Popping Up In Total On Form?

Mar 11, 2011

I'm creating a web form that allows users to select from a list, choose a quantity and have the total for that quantity calculated, but when I run the html, I get Nan in the total price box. The problem starts with the calc price function. I've tried eval(), parseFloat to change the text to a number, but I think I'm putting the code in the wrong place.The first part is the javascript code (I have linked in a separate file) with the html below it.

function todayTxt() {
var Today = new Date();[code].....

## Form Selection(s) Must Total 100%?

Dec 3, 2010

I have a form with a question that has about 15 options. The user selects one or more options by entering a percentage in the box next to the option.Entering any percentage in a box means that option has been selected.Here's where (I think) I need some javascript: The total of the percentages a user enters across all options has to total 100%.

Would like to do this client-side with an alert, as opposed to server-side. The form is complicated and long. Ideally, the user should not be able to proceed to the next question unless the percentage totals 100. But I'd settle for validating it on clicking the submit button.

## Total Amount In Form Field

Mar 17, 2005

Say i have 4 text form fileds like this:

|-Quanitity1-|
|-Quanitity2-|
|-Quanitity3-|

|-TotalQuanitity-|

As soon as a user types in an integer into one of the quantity boxes the total quantity gets updated. How exactly would i do this? I can make it update the total quantity after a user hit's a Validate button or any button, but i cant make it update in real time.

## Total Currency Form Cells With \$?

Sep 1, 2011

## Calculate Total Cost On Booking Form?

how to achieve client-side calculation on my company booking form, using Javascript.The total amount for accommodation is calculated based on the room type (single or twin), zone chosen and meal plan (which then assigns a certain rate per week,so for example Single room, Zone 2, Self Catering would be �165 per week).

## Calc Subtotals And Total On Js/php Looped Form

Apr 14, 2005

I have an alteration to do on a multi-page form which was previous in use for single item selection and calculations only.

Now the form has to be altered to process multiple items. My difficulties lie in tackling the javascript calulations for a form that populates dynamically with as many items as the user has previously selects.

Item recordID's are POSTed to this form as an array. The array determines which item records are pulled from the database via sql. The form has, for each record, a textfield for item quantity and subtotal, and a hidden input that holds the item cost price.

Previously, this was calculated by targeting hard coded form field names, however the dynamic nature of this form requires dynamic targeting or a different field naming strategy all together so that the javascript function can iterate through the form fields and calculate subtotals and total on the fly.

Here's the code so far;

The previous calculation function for the single item form:-

function calcForm(){
qty = parseFloat(document.confirmTicketPurchase.ticketQty.value)
if (isNaN(qty)){
alert("You must enter a valid number into the Enter Quantity field")
return false
}
if(qty <=0 || qty % 1 != 0 ){
alert("You must enter a quantity of tickets between 1 and 999 only")
return false
}
costPer = parseFloat(document.confirmTicketPurchase.perticketCost.value)
total = costPer*qty
document.confirmTicketPurchase.ticketCost.value = total
return true
}
I have to edit this javascript function to work with the following form and edit the form field names to suit the function.

The new form :-

<form action="#" name="confirmTicketPurchase" id="confirmTicketPurchase" method="POST">
<tr class="trTopRow">
<td colspan="2">You Have Selected The Following Ticket/s</td>
</tr>
<?php do { ?>
<tr class="trOdd">
<td colspan="2"><strong><?php echo \$row_rsTickPurchase['ticketName']; ?></strong></td>
</tr>
<tr class="trEven">
<td width="36%">Enter Quantity:</td>
<td width="64%" class="algn_R"><input name="ticketQty" type="text" id="ticketQty" value="1" size="4" maxlength="4" onkeyup="calcForm()" /></td>
</tr>
<tr class="trEven">
<td>SubTotal:</td>
<td class="algn_R">
<input name="perticketCost" type="hidden" id="perticketCost" value="<?php echo \$row_rsTickPurchase['ticketCost1']; ?>" />
<input name="ticketName" type="hidden" id="ticketName" value="<?php echo \$row_rsTickPurchase['ticketName']; ?>" />
<input name="ticketID" type="hidden" id="ticketID" value="<?php echo \$row_rsTickPurchase['ticketID']; ?>" />
\$ <input name="ticketCost" type="text" id="ticketCost" size="12" readonly="true" /></td>
</tr>
<?php } while (\$row_rsTickPurchase = mysql_fetch_assoc(\$rsTickPurchase)); ?>
<tr class="trOdd">
<td>TOTAL:</td>
<td class="algn_R">\$
<input name="total" type="text" id="total" size="12" /></td>
</tr>
<tr>
<td colspan="2">Confirm your selection and proceed to Step 6</td>
</tr>
<tr class="trbtn">
<td colspan="2"><input name="userEmail" type="hidden" id="userEmail" value="<?php echo \$_SESSION['email']; ?>" />
<input name="step" type="hidden" id="step" value="6" />
<input name="Submit" type="submit" class="loginBtn" value="Confirm" /></td></tr>
</table>
</form>

The calc function is called onLoad and during user input with onkeyup. I'd really appreciate some tips as to how to tackle this one. Currently I'm working on how to get the field names for each form field unique via the php loop which populates the form.

## Multi Selection Form With Each Being Added Up To Reach Total

Sep 29, 2010

I am just beginning to try to learn some js, and am making a site which requires a multi selection form with each being added up to reach a total. This sounds like a standard form, but this is a little different. I have files in megabyte sizes, from which people would choose what they wanted, and the total deciding how many dvds would be needed to store that many files...and this total could then be added to a js shopping cart. By the way, there is nothing illegal or pirated with the files in case you have any concerns.
