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 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.

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.
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.
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 trying to simulate a simple checkout page where a user inputs the quantity of merchandise that they want in multiple text boxes. When they click "calculate" it calculates the subtotal, tax, and total. As it stands my calculate function works if I do quantity * price for each text box and then add together. I would have to do this 9 times! :eek: I would like to use an array but I am not exactly sure how to use it to do calculations. I know I need a loop (which I have written) and an array (which is written also).
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:
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'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 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 am having some difficulty in constructing a window.confirm() function that works with my code.So if the form data is valid, I need to use a window.confirm() dialog box to show the user's total cost based on the rental rate of equipment chosen and the reservation period. The user must accept the cost by pressing the confirm button, and if user cancels do not submit data.I have written this code but cannot figure out how to find the number of days from the 2 date fields and use that to calculate and display the total cost.
//confirm submit and display rental cost var equip = document.forms[0].equipment.value var pDate = document.forms[0].pickupDate.value[code].....
CONDITIONS:If a person selects a Friday Class but not a Saturday Class the Total Cost Field will automatically enter $99.If a person selects a Saturday Class but not a Friday Class the Total Cost Field will automatically enter $99 as well.If a person selects both a Friday & Saturday Class the Total Cost field will automatically be $159.I found the following code and so far only have it changing when a Friday class is entered. I have no idea where to go from here
