now the problem occurs when i put more rows there then the javascript function does not work anymore, my ultimate goal is to create a function to add tablerows with javascript, but i'm trying to create the update function with a static situation first.
I have a program in which a user must enter number of books and price and then calculate the total cost of the items, i have tried and tried to get it working to no effect can anyone see where i have went wrong.
I'm trying to add the total number of costs depending on the rows added to return the subtotal then later add the service charge which gives the total grand amount.I also need to add the item number when a new row is added.

I'm trying to get the total price of a dropdown value to change.eg. When Option 5 is selected the total at the bottom should display �12.00.I've already managed to get this code working with radio buttons but can't seem to get it to work with dropdown menus.
Firstly, I got this script which gets values and automatically calculates it and shows result. Script: <script type="text/javascript"> function calculate(f){ var prod=Number(f['users'].value); var quan=Number(f['months'].value); var tot=prod*quan; f['total'].value=tot==0?'':tot.toFixed(2); } </script> <ul><li class="bold">Users</li> <li> <select name="users" onchange="calculate(this.form)" id="users"> <option value='1'>1</option> <option value='2'>2</option> </select> </li></ul> <ul><li class="bold">Period</li><li> <select name="months" onchange="calculate(this.form)" id="months"> <option value=''>Select Months</option> <option value='1'>1 Month</option> <option value='2'>2 Months</option> </select></li></ul> Total: <input type="text" name="total" readonly="readonly">
What I'm trying to make is, the total, to be in a div and not input type text Something like <div id="total"></div> I don't like because it shows in form, I want it directly. One more thing, is possible to make the default price 0.00 ? and when selecting automatically changes to price..
When I compile this I get no errors, however when I try to run it, it does not work. What should happen, is an output dialog box should appear saying the total for tickets, total tax, and total for tickets with tax. This is not what happens. This is what I have written: This program will ask for the number of tickets you wish purchase. It will then calculate the total price of the tickets and the 9.5% sales tax.
import javax.swing.JOptionPane; public class TicketCost { Constants static final double TICKET_PRICE = 10.00; static final double TAX = .095; public static void main (String [] args) { Local variables int Nbr_Tickets = 0; double Tax = 0; double Total = 0; String InputStr; String outputMsg; InputStr = JOptionPane.showInputDialog ("Enter the number of tickets to purchase"); Nbr_Tickets = Integer.parseInt(InputStr);
Created message outputMsg = "cost of tickets: $" + String.format("%.2f", Nbr_Tickets) + "Taxes: $" + String.format("%.2f", Tax) + "Total cost of tickets to A Beautiful Mind: $" + String.format("%.2f", Total); output message JOptionPane.showMessageDialog(null,outputMsg,"Total cost of tickets to A beautiful Mind",JOptionPane.INFORMATION_MESSAGE); System.exit(0); }}
And when I run it this is what I get: ----jGRASP exec: java TicketCost Exception in thread "main" java.util.IllegalFormatConversionException: f != java.lang.Integer at java.util.Formatter$FormatSpecifier.failConversion(Formatter.java:4045) at java.util.Formatter$FormatSpecifier.printFloat(Formatter.java:2761) at java.util.Formatter$FormatSpecifier.print(Formatter.java:2708) at java.util.Formatter.format(Formatter.java:2488) at java.util.Formatter.format(Formatter.java:2423) at java.lang.String.format(String.java:2845) at TicketCost.main(TicketCost.java:35) ----jGRASP wedge2: exit code for process is 1. ----jGRASP: operation complete.
What I'm trying to do is, a jquery script to show in real time the total price. I got this: <li>Users</li> <li> <select name="users" id="users"> <option value='1'>1</option> <option value='2'>2</option> <option value='3'>3</option> <option value='4'>4</option> <option value='5'>5</option> <option value='6'>6</option> <option value='7'>7</option> <option value='8'>8</option> <option value='9'>9</option> <option value='10'>10</option> </select> </li>
1 Month and 1 User price should be 0.50 USD +1 Month = + 0.50 USD + 1 User = + 0.50 USD Example: 5 Users + 2 Months = 3.50 USD I wanna make the jquery to show the total price at li class="price".
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'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: -
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 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.)
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.
1) I need to calculate a total dynamically.I have an input with the price of a product and next the amount. As the users inserts the amount I would like the total box to give the amount*price number. So if the price is 3 and user inserts:
1 - then total should display 3. Then the user inserts 0 (amount is now 10) total should display 30.The problem is that when i ask for the value in the onkeyup event of the amount input i don't get the value with the last key (same with onkeypress event). I could add that number (if it's a number) or see if it's backspace or any char but there should be an easy answer.I solved it by setting a timeout and using a callback function so as to have the latest value of the amount but it's an awfull solution (though not expensive in code).
2) Avoid focus reset when i update the value of the amount.I've managed to add commas on the fly to the amount like when the user types "1000" the number displayed is "1,000". In firefox it works great but in IE and Chrome it resets the focus each time i update the field. So when you try to move your cursor back it returns to the last position (maybe because the value of the input is changed).
here's my code:
Code:
function updatePrice(){ setTimeout(function(){callback()}, 10); }
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.
how javascript works and have inherited a website that contains a form that uses the calculate total function...which only works in IE. I've searched all over the net trying to find a solution to get this working across all browsers but not having much luck (mostly due to lack of experience)
I have a Javascript that calculates and displays how long, in minutes and seconds a user has been in online(Google Gears development) mode on a given web page. I need however, to modify the script so that it calculates and displays how long the user has been online on the web site. For e.g. on page 1 for 2 minutes 12 seconds. Moves to page 2 - total time on page 1 and 2= 4 minutes 13 seconds. My script (see below) starts a second counter then converts that to minutes and seconds. I have tried passing the secVar0 variable in the url but that comes back "undefined".

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). There is a table of rates here : http:[utl].....The code would then use the arrival and departure date to calculate the number of weeks, add a booking fee of �50 and output the total amount.The form is located here: http:[url]....
There are two text boxes in a HTML form.The first text box takes the time when the user starts to work on a project. The second box takes the time when the user stops working on that project.Now, I would like to calculate the total time worked on that project for that user. That is (stop time - start time). I tried few things without success.
