# Calculate Checkbox And Drop Down Values?

Oct 19, 2009

I have the following code working with the checkbox options but once I added a drop down menu with values, it doesn't calculate it. I've done some different things to try to add the drop down to the function but nothing would work that I've tried so far.

I have it setup so when a box is unchecked, that option is taken off the price, the drop down should do the same to switch between the options price.

## Auto-calculate Values

Sep 6, 2007

I am thinking of how to write the code for this:

There are 3 textboxes, each labeled:

TOTAL
rd_PROPERTY_VALUE
LTV

Both “TOTAL” and “rd_PROPERTY_VALUE” allow you to enter any number (e.g. 10000, 2500, 12345, 100.10, etc.). So whenever I enter numbers in both of them, the 3rd read-only textbox will automatically divide TOTAL by rd_PROPERTY_VALUE then times it by 100 and show the calculated value in the “LTV” field.

For instance it should mathematically appear like this:
(TOTAL / rd_PROPERTY_VALUE) * 100 = LTV

Can anyone give me any references to this?

## Calculate Multiple Values

Apr 17, 2007

I have a table which I have made work where I put some values in and the script works out the result on an onChange event.

My question is that I want to make the table rows populate from a database so each of the javascript values will have to be unique for the value to be worked out on a specific row calculation.

The code as it is works out the single value but how would i go about using the mechanics of the code to apply to multiple lines in the table. Code:

## Combining Two Or More Text Drop Down Boxes To Calculate A Price?

Dec 13, 2011

I'm creating an online enrolment form for my company, who are a training company. Users enrolling on the course must make three choices - The level of course, the size of course and whether they wish to attend a workshop or study by distance learning. The combination of these three factors will determine the price. I'd like to have the price automatically calculated using javascript and displayed on the form before they submit. Can anyone give me an idea of how to do this?There are three drop down boxes for users to select their course. They are: -

Level of Qualification:
Level 3
Level 4

## Calculate Field Values Using Javascript

Feb 26, 2006

Can someone explain how I can use javascript (I am assuming this is the best
way to do it) to add two field values together. I.e. field 1 plus field 2
equals field 3 (this is in a php form)

Also how can I set a field to be a value depending on what the user selects,
i.e. they may have eight items to select from and each one has a different
value.

The above javascript will then use that value to add to another field value
to give a me a total value....

## 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.

## Resetting Values When Hitting Calculate Button?

Nov 3, 2011

I am having trouble with figuring a way to set my loop up to reset values of the different coin values. Example, when I put in 78, and click calculate, it tells you how much of each coin would be given back. My problem is that I set it up and run it, but when I put different values in back to back to calculate, some of the fields don't reset.

var change_out = function(){
do {
var money = document.getElementById("cents").value;

## One Checkbox With Multiple Values?

Nov 2, 2010

I am trying to do some JavaScript calculation with checkboxes, and have been able to modify some codes to do bits of what i want to do. (Screenshot attached) However, i want each checkbox to have multiple values, and therefore multiple results.

I can't find any examples, but i've come across something similar with Radio buttons [URL].. I don't 'get' the example enough to proceed. My question is, is it even possible to do with a checkbox, and if so how do i go about doing it please?

The Javascript code:

function count() {
var item1price = 10;
var item2price = 50;
var item3price = 1100;
var item4price = 100;

## Multiple Values For Checkbox?

Nov 2, 2010

I am trying out checkbox total calculator code examples, which automatically calculates the values of checked/unchecked items, and so far so good. My question is if it's at all possible for each checkbox to have multiple values, so i can have different sets of totals? I have been looking for examples all over with no luck. I have seen examples for Radio buttons, which separates the different totals with commas, but i don't have enough JavaScript experience to understand it fully.

## Display Checkbox Values On Alert?

May 20, 2009

So, I am in a Web Development class right now for my liberal arts science credit. We are on a lab dealing with JavaScript and half of it is making the values of some check boxes and stuff show up when the user clicks a "Display" button. I'm not sure I'm explaining it well. Here's the lab:

# In lab 6 you wrote a JavaScript function that displayed the name and email entered from the form. Extend that function to display all of the information the user entered in the form (name, e-mail, region, special interests, interest level, and comments). See if you can nicely format what shows in the alert message. The following hints should help:

1. The first step is to make sure that each GUI field has an id attribute set. For example the name field might have id="name". Remember, every id value must be unique. Two radio buttons will have the same name attribute value, but their id attributes must be unique. You need to do this so JavaScript can find the tags using the document.getElementById method.

2. To display your checkbox information, you will need to include logic as described in the following steps. Once you do this, do the same thing for the radio buttons.

1. Assume you have a checkbox with id="cherokee". Of course, your id attributes will likely have different names. The general steps will be the same, but substitute your names where I'm using "cherokee".

2. The following statement creates a Boolean value (true, false) that determines if the user checked the cherokee checkbox. The checked property in checkbox and radio button objects gives this information.
