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.
I cannot calculate all total amout about this..How can i do it.?? here is coding:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

<script type="text/javascript">
function startCalc(){
interval = setInterval("calc()",1);
}
[Code]....
i have the following html im just wondering how will i go about selecting a product from the list then automatically on the change showing its unique cost in the cost text field.
Then depending on the quantity purchased of that product selection and what radio button is checked (cheque add 2$ total) (credit card increase total by 1.5 %) (cash add $5 to the total amount) and calculate the total amount of the product. Code:
I have a text field. I want the text field to change / be calculated on the action made on the dropdown menu... So if I select Debit card.. it should leave the amount as is..If I selected Credit Card it should add a percentage to the Amount.

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.
i have a form with arrays, I want to sum different arrays and display the total in a array field in the form itself.i have this code
<form>
do {
$x++;
[code]....
I need the value of my drop down box options to contain size information rather than price. However I would like to be able to calculate a price for the items based on what size the user selects as well as the quantity. Below is the code I came up with (which doesn't work obviously)What can I do to get this to work for me?

i want the code below to display the total loan repayment amount instead of the monthly payment payment = principle * monthly interest/(1 - (1/(1+MonthlyInterest)*Months)) , eg if if l0an is 20$ payment is in 4 months, intrest rate is 15% display = amount to be repaid.

javascript coding portin of the web page.Need it to use the pop up alerts that have been input above and also to calculate the order upon entering a correct amount showing subtotal, tax, and total.
I have a webpage at http://manoamano.org/donate/donate2.html thatshows that total amount donated with Google Checkout.Example: "$7,440 donated so far"I would like to update the dollar value ($7,440) on the page whenevera new donation is submitted through Google Checkout.I can't figure out how to trigger the javascript when the Checkout issubmitted, also I would need to get the variable value from the formnput box. This needs to get updated on the server side so that the new amount appears when the page is accessed in the future.
View 4 Replies View Relatedlet me try to explain better what I'm trying to do. I'm a real newbie I don't know much javascript but I understand more or less the logic behind it... tell me if this solution should work and if you know how to do it please show me. [URL]... I need to make div#photo's width to match the total width measurement of all the images it contains. If you load the page and you don't touch the size, it will work fine... but that's not realistic. If I resize the page, which will happen often on this kind of page (I'm assuming), the whole thing goes haywire (try it, scroll to the last image and resize the page you'll see what I mean). What can I do? Is my idea the right solution? Am I not explaining this clearly enough? Let me know please, I'm desperate. I've been trying to get CSS to do this for me for 3 hours now. Nothing works.
View 6 Replies View RelatedI have 5 Numeric fields in my from, I am using onkeyup to check for numeric values only, now I have a total field also. I would like to have a sum of the values entered in the 5 fields to be shown automatically on this total field.
View 2 Replies View RelatedI 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.
Here is my dilemma:I am preparing a mock website that basically sells crates of juice.I have 10 different types of juice available to my customers.If they buy 5 crates, then they get a discount of 12.5%. How on earth do I set up an array for my various juices, with an input field for the amount of crates they want?i.e. Orange Juice(0 shows in the input field until customer enters amount required).
Once they have made their selection, I would like to show it on screen, like an Invoice or something, or perhaps just a message that says you have ordered this, this is what it costs, with 12.5% discount if 5 crates have been ordered.
[URL]. Users fill in a form which has items of furniture, so they enter a number next to each item of furniture. The HTML uses text fields. When the form is submitted, the form is submitted to a php script that emails the results to myself. I am trying to also have a javascript function which runs before the php script runs. This javascript works out the cubic footage of all the items. If a user put "3" in the sofa text field, and I have defined that a sofa is 45 cubic feet, then the javascript will multiply 3 * 45. It will do a similar thing for all items of furniture, then add them all up to give a total cubic feet. I want that total field to then sent as a variable to the php script, along with all the other variables.
My code so far (which doesn't work)
<script language="JavaScript">
function calculate(){
var sofa_3_seater = document.getElementById('sofa_3_seater').value*45;
var sofa_2_seater = document.getElementByID('sofa_2_seater').value*30;
var armchair_large = document.getElementByID('armchair_large').value*15;
var total=sofa_3_seater+sofa_2_seater+armchair_large;
document.getElementByID('total').value = total;
}</script>
I have used a hidden field for the total value:
<input type="hidden" name="total" value="">
I want the javascript result to change the value of the hidden field that is called total. Then I want it all to be posted to the PHP script and email everything to me, including this newly calculated total field!
i am currently developing a cart for a website at my company.What i am attempting to do is update the grand total field dynamically as the product total (determined by quantity & price) are being populated.Each product in the cart is being generated by a foreach (php) reading from a mysql database.As the total values are not being prepopulated im not exactly sure what the logic would be to get the desired values.
I will also mention im relatively new to the whole web development area, i started begining of this year and feel i could still learn alot about the 'logic' of a computer.If anything is unclear about what i stated above feel free to request additional information.
I have two drop down menus. I want two values to be added based on what they picked and then outputted to a text field to show a grand total in a dollar amount.
This is what I have:

Note I haven't did any type of code for the 2nd drop down menu just in case anybody says I don't see anything. I was working on trying to get started in the right direction.
This is my code to add and delete dynamic rows and auto calculate the amount field by multiplying qty and rate.

I have a web form with several fields. If I copy & paste from a RTF document into a field, the javascript validation and field length are bypassed and cause the form to fail.
View 3 Replies View RelatedI am trying to add up some fields, it works but to get the total you have to click on the total box. Is there any way of getting it to total automatically i.e. when the user enter a quanity it will show the total straight away without having to click the total box.

I have a textbox for the overall total, and i want it automatic subtract the total earn and total deduction..
I am making making class project and faced with some problems. I have found script (here) and learned.
1. not updating row number and row ID after deleting rows
2. not updating total sum if user change quantity
3. not updating grand total after deleting and changing quantity

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