Calculate Subtotal - Tax And Total Using Multiple Text Boxes
Apr 15, 2009
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).

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'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

i have a multiple page form where on one page i ask my user to enter a number into a textbox. i would like to know how to get some textboxes to appear on the next page in relation to the number they enter on the first page. i.e. if they enter 10 in the first text box, 10 textboxes appear on the next page for them to enter data into and then press next to go onto the following page.

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.

require "../config/bpts_config.php";
// Start the session
//session_start();

I've a page where I'm calling record from Database. Each record has an
ID and a text box displayed on the page. When the user fills in the
values of a text box, depending on the values of the text box i've to
do some further work. For eg. I've to add two records if the textbox
value of 2 records is same.
I'll try to create an example here
<-----this is from the DB-------> <-----this is form field--->
ID Task Hrs text box
1 adsfsd 1 a <---- user fills this
2 asdf 1.5 b <---- user fills this
3 eyst 2 a <---- user fills this
4 dghjfghj 2 c <---- user fills this
5 xdfb 1 b <---- user fills this
6 tyety 1.5 c <---- user fills this
________
| Submit |
--------------
So the user has to add hrs of those boxes for which have same values
entered by user. such as adding hrs of record 1 and 3 since both have
"a" entered by the user, adding record 2 and 5, as both have "b"
entered by the user and so on and so forth.

I have a couple of radio buttons that hide and reveal DIV tags. Here is what I'm trying to do:
1) radioBTN1 is clicked it reveals DIV1 with multiple text boxes in it
2) radioBTN2 is clicked it reveals DIV2 below DIV1 with multiple text boxes in it
3) the user fills in the text boxes in the DIV2
4) user changes mind and clicks radioBTN1 again to hide DIV2
5) when DIV2 is hidden it resets and clears all previous information
IS this possible to do with javascript? 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.)

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'm primarily a database programmer (Mysql and PHP) but I have some Javascript programming and I have been programming in other languages for over 25 years.
On to my problem:
I'm trying the create a function in Javascript which will take a variable from three different text boxes and show the net result in a fourth text box that is ReadOnly. This is all on the same page. All three text boxes have other Javascript scripts formatting the value in the text boxes.
Real example (simplified)....

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".
Code:
if(request.responseText != "" && request.responseText.indexOf("404 Page not found") == -1)
{
c=0;
