Here is a sample form that I just made up. I would like a somekind of
script that when each button is checked or unchecked to dynamicly add or
subtract the total.

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.
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>" );
im wanting to add check boxes up to create a total sum at bottom of the form or anywhere for that matter.im wanting to add the values up of the check boxes and then the total amount of checked boxes appears in the total amount. also ive been trying to get it when you uncheck a box the amount goes away from the total amount.here is what ive got
<script type="text/javascript"> function initialize(){ Total = 0;
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
I have a costestimatorslider using jquery ui slider as:
$(function() {
As you can see I can add the value from the slider ui.value without any problem.Now I would like to be able to ADD or Extract the$('.cost') value to other value as Total(total=parseInt($('#total').html());.) which is Sum of some other calculations stored in a HTML table cell in the page as:
I tried to do it by this way butFirstof all it doubled the value which makesense and it's wrong!, besides itcouldn'textract the cost from the total.
I 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.
Below is my code <html><head><title>Online Order</title></head> <body bgcolor=white onLoad="document.arith.total.value=eval(0);
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).
Below is the script and form fields I am working with. What I want to do is sum the two textbox fields and have the result show in the total textbox. The code works fine and the total textbox is updated with the value of form1.basic. The problem occurs when I add the "+ parseInt(document.form2.supporter.value)" code in the script section.
I have a page that lists a bunch of golf clubs. They are ordered by catagory (drivers, woods, etc) When you click on a check box the javascript puts the price in a sub-total box. I need it to also add up the total for the page.Here's a link to the page:
http:[url]....Here is the javascript at the top:
Code: <script language=javascript> var a=<?php echo $row_recDrivers['cPrice']; ?>; //set driver value. var b=<?php echo $row_recWood['cPrice']; ?>; //set wood1 value.[code].....
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.
My requirement is to develop a simple form with checkboxes which when selected calculate a price based on the value assigned to the checkbox. The form and calculations is working great but i need a few final touches which i can't work out.
1. I want the total to be in plain text and not in a text box maybe just drop the total value in a DIV.
2. I want the form to start with a default value for example 200, i have tried adding a hidden checkbox with a value of 200 and setting it to checked as default but it doesnt display 200 in the total when i first load the page it only calculates it when i select the first box and i need it to be displayed as the total even if no options are selected.
I am making what I call a PM (Preventive Maintenance) Kit list. My users will use this list to generate a printable sheet to tell me what they used out of there kit. The list includes pricing per part and I would like the list to calculate the costing as they enter each item. So a total per line and an overall total cost.
I have included a snap shot of the page and below is the code. I can do this sort of thing on a small scale with just adding two lines but I am not sure how to modify it to handle this scale. You can see the script towards the bottom of the page. That is my lame attempt to make the per line costing happen but NOTHING happens.
<?php require "../config/bpts_config.php"; // Start the session //session_start(); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 3.2//EN"> <html> [Code]...
automatically calculate a total. The script pulls a price, which is given from a database to a hidden form field. Then once the quantity is changed the bottom form field automatically updates the price. Here's my script if someone could possibly point out why this might not be working (or is my logic flawed.)
how to get the total column automatical gets update when user inputs a value in column 1. i believe its some thing to do with javascript onfocus(). i don't know how to do it.
I am making a mock website where the user make their own computer by selecting items from drop down menus. Then a value of the item comes up below. this works but i am having trouble adding the numbers up for the total cost.
Here is my code: <html><head><title>build</title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"><style type="text/css"> </style></head> <body> <script type="text/javascript"> .....
I can get the number of contributers to add up but not the total amount of dollars they contributed. I am not sure if my function is wrong or if I am just confused with what variable to output for the dollar amount total.
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 looked around for a solution but could not find one. I am trying to find combinations of numbers that can add up to a total. The numbers available and the total are different each time.
For example, I have an array that contains the following numbers: [16,12,8,6,4,2] I want to find the combinations that add up to 140, like this:
I have a page that has a total field that will have a value when the page is loaded. I also have a few select options that modify the total via an onchange event. Problem is, when i change a select option twice, I cant work out how to get the correct total happening instead of just adding more to the total. I'll show you what I mean.. Code:
