# Adding Total Value Of Combined Products?

Feb 18, 2011

I have a program that allows the user to input a product number from 1 to 5, and the amount of each product number sold. After all values are added, the program is supposed to calculate each product's total retail value, as well as the total retail value of all five products combined. The program runs fine, up until the end. I got all my alert boxes working, and the program is doing the multiplication as it is supposed to. However, when I get to the end, I receive "Last weeks total retail sales are: \$NaN".

My code:
var productNum;
var quantity;
var prodPrice1 = 2.98;
var prodPrice2 = 4.50;
var prodPrice3 = 9.98;
var prodPrice4 = 4.49;
var prodPrice5 = 6.87;
var total1;
var total2;
var total3;
var total4;
var total5;
productNum = window.prompt( "Enter a Product Number (1,2,3,4,5):", "1" );
quantity1 = window.prompt( "Enter the quantity sold" );
productNum = window.prompt( "Enter a Product Number (1,2,3,4,5):", "1" );
quantity2 = window.prompt( "Enter the quantity sold" );
productNum = window.prompt( "Enter a Product Number (1,2,3,4,5):", "1" );
quantity3 = window.prompt( "Enter the quantity sold" );
productNum = window.prompt( "Enter a Product Number (1,2,3,4,5):", "1" );
quantity4 = window.prompt( "Enter the quantity sold" );
productNum = window.prompt( "Enter a Product Number (1,2,3,4,5):", "1" );
quantity5 = window.prompt( "Enter the quantity sold" );

total1 = document.writeln("Total for product 1 is \$" + (prodPrice1 * quantity1) + "<br />");
total2 = document.writeln("Total for product 2 is \$" + (prodPrice2 * quantity2) + "<br />");
total3 = document.writeln("Total for product 3 is \$" + (prodPrice3 * quantity3) + "<br />");
total4 = document.writeln("Total for product 4 is \$" + (prodPrice4 * quantity4) + "<br />");
total5 = document.writeln("Total for product 5 is \$" + (prodPrice5 * quantity5) + "<br />");
document.writeln( "<h1>Last weeks total retail sales are: \$" + ( total1 + total2 + total3 + total4 + total5) + "</h1>" );

## Invoice Form :: Calculate Grand Total Of Products And Add Rows?

Jun 7, 2010

I'm trying to create a Invoice form with javascript. Basically, my invoice form should have the field item, cost, quantity and product total.It shd have a function to allow the user to add rows if they want more than one item. In the end, there should be a sub total. I am able to use javascript to calc the total of each product for only the first row. If I add rows, the Product total script don't work.This is what I have so far:

Code:

How to subtract totalgift if my condition of donateamount is lesser than the totalgift trigger.

When the field is selected and the DonateAmount is trigger, I need to subtract the entered amount on the field selected to the TotalGift and put the field selected to zero "0" and TotalGift to original amount which is less than the amount entered on the field selected. I have some code that I created but it doesn't work. My initial javascript to calculate all the total is below assuming that DonateAmount is already selected = 25:

Below is what I am trying to do but it doesn't work. If the first input field is selected and user enter amount greater than the TotalGift, alert will pop-up then and the amount entered by the user automatically added to the TotalGift. So what I wanted to do is to subtract the amount entered to the TotalGift so it will go back to the original amount before the addition occurs. I know it is possible but I just can't get the right code.

My html code below which I have 18 input fields but all of them only optional wherever the user wants to input number. I will only include some here. Code below works, please ignore any missing code. I just need the calculation code to work.

## Adding Multiple Input Boxes And Getting A Total Different Number Every Time?

May 19, 2011

ave this form which gets created by pulling stock/products from a database using PHP and beside every product in the row is a little box for input and in there the user can input the quantity of the product they want. Sometimes only 2 products will be outputted and other times 10 or more.What I want to happen is when the user enters in lets say 3 for the quantity of a certain product I want to get a total for how much 3 of that product will cost so I just do 3 multiply by the cost (which I have from the database) and then display the total cost down under where the list of the available products are and I want all this to happen dynamically obviously not using PHP because I don't want the page to have to reload every time they enter in a new quantity.

I know how to display text and stuff in certain divs with certain ID's using Javascript but I just don't know how to keep track of a form and do what I want to do when the number of inputs in the form can range from 1 to 10 or more. Im thinking of some sort of counter which gives every input a different ID like add 1 at the end of the ID name of the input as the PHP script loops through the database query displaying the products but I still don't know how to go about the Javascript side of things

## 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).

## Products From A List On Another Individual Page?

Apr 17, 2009

I was wondering if anyone was aware of a script that would reccomend products from a list on another individual products page?

I would like something that will list three products that a customer might be interested in when they are viewing an item on my site.

I have an ecommerce site where I was told that I needed to use javascript to avoid paying alot of money for something very complex and more than what I need.

Does anyone know if this is possible and if so, do you have a script to get me started?

## "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.

## Set Up Products Page With Swatch Rollovers And Detailed Views?

Nov 3, 2009

Ultimately I'd like a set up resembling http://shop.lululemon.com/Swift_Tank...30/p/1230.html

Where you're able to click a swatch color and get a thumbnail of it on the model and a thumbnail of a fabric detail that you could then enlarge. I'm not sure how to go about this. I'm able to do it with one thumbnail, where when you rollover the various swatch colors, the thumbnail of the model gets replaced. However I'm unable to add in the 2 other thumbnails (on that site they're using 3 but I would only need 2) that would change at the same time, where you could switch back and forth from at detail of the model and the fabric.

I don't necessarily need the zoom function, but if it is possible to do all of those that would be good too.Otherwise I just need help coding how to at least get the swatches to change 3 images upon mouseover and that 2 of those images would be like the 3 thumbnails on the link above and would replace the larger thumbnail once clicked.

## JQuery :: Form Validation Combined With Ajax

Apr 12, 2011

I'm trying to make a username form validation combined with ajax but I'm stuck at 1 point. I need to use a var that is outside of my \$.get() function so that I can add the function to the validate plugin.

This is what I have:

As you can see, I'm trying to change the value of "var result" to true, but since that is outside of my \$.get() it doesn't seem to happen. I tried to put the return command inside the \$.get function, but then my validator always keep saying it's a false check.

Is there anyway I can call that var inside my \$.get function?

## Calculate Combined Value Of Html Fields, Printing Value To Another

Jan 29, 2010

I have a few html fields in a form that use PHP in order to calculate a combined value and then inserting it into the database. However, I would want that value to be displayed to the user as well before they insert it, just so they can verify that the value is correct. But how do I go about and do this?

It is probably very simple, but I'm a PHP programmer and have very little knowledge of JavaScript. Basically this is what I would want:

<field 1> -20 +(or -, depending on user input) <field 2>
Result of that to be displayed in <field 3>

However, I only want the -20 to calculated when something is entered in <field 1> so that it does not say -20 in the output field before the user even started typing a value.
