Exploding Values And Calculating Totals ?
Apr 1, 2009
I have a slight problem with creating dynamic quotes. Basically I have two select boxes and need to calculate a total in real-time using javascript and insert into input.First it needs to explode out the machine price and term years from the values and then calculate.
Here an example: A machine costs �4000 and a term of 2 years(60 months). The calculation would be (4000/60)*3 = �200
<select name="machine">
<option value="2005 - Almida XAS47 (660 Hours) �4000">2005 - Almida XAS47 (660 Hours) �4000</option>
</select>[code].....

Our basketball officials chapter is implementing an on-line evaulation form and I have been asked to create the form. The form itself was not a real problem but the officials would like the form to automatically total the points in each Section (A thru F) and automatically total the six sections into a grand total. Right now I simply have a number of defaults: points per item, Section total, Grand total and a 'warning" that they need to update the totals if they make any changes to the default values. I thought could establish a variable for each section, perform a loop function to derive a total, then add the variables together for an overall total, but it doesn't seem to be working. I'm copying just a portion of the code (for Section A and Section B) below, along with my attempt at creating "functions" (at the end of the code) to do the math. (Not observed is treated the same as a "0")I'm probably missing something very simple but just don't see it. Any ideas on what I need to change?

I've managed in the past to cobble together a few simple scripts.
I have an html page, with numerous tables in this format:
<table class="tableClass" id="tableID">
<col class="date" />
<col class="reference" />
<col class="amount" />
[Code].....
This (apparently) totals all 'amount' cells in the page, and writes it in *all* the 'total' cells - close, but obviously I'm not correctly specifying that each total should be displayed in its parent.

I need help in calculating a score from a row of drop-down values.
I need to use the onChange to tally the score as the user moves across
9 categories (with drop-down selection of 1-9 or N/A) multiplied by a
weighted score. The final column for each employee would be the
calculated score. I know how to accomplish this with vbscript but I
need it to process on the screen so the user can see the calculated
score as they make selections. Also the code needs to execute as many
times as there are employee rows.(loop) I don't know how to do this
with Javascript
Here's the VBscript with the variables involved
Var S1 = Category 1 Weighted score
Var S2 = Category 2 Weighted score
Var S3 = Category 3 Weighted score
Var S4 = Category 4 Weighted score
Var S5 = Category 5 Weighted score
Var S6 = Category 6 Weighted score
Var S7 = Category 7 Weighted score
Var S8 = Category 8 Weighted score
Var S9 = Category 9 Weighted score
D5 = 0.92
Var Q11 = Category 1 drop-down Value(1-9) * S1
Var Q22 = Category 2 drop-down Value(1-9) * S2
Var Q33 = Category 3 drop-down Value(1-9) * S3
Var Q44 = Category 4 drop-down Value(1-9) * S4
If (Category 5 Value = "N/A") THEN
Q55 = ' '
Else
Var Q55 = Category 5 drop-down Value(1-9 or N/A) * S5
End If
Var Q66 = Category 6 drop-down Value(1-9) * S6
Var Q77 = Category 7 drop-down Value(1-9) * S7
Var Q88 = Category 8 drop-down Value(1-9) * S8
Var Q99 = Category 9 drop-down Value(1-9) * S9
If (Category 5 = "N/A") THEN
Var FinalScore = round(((Q11 + Q22 + Q33 + Q44 + Q66 + Q77 + Q88 + Q99)
/ D5),2)
else
Var FinalScore = round((Q11 + Q22 + Q33 + Q44 + Q55 + Q66 + Q77 + Q88 +
Q99),2)
end if
Can anyone help me converting this to javascript?

Well, it's been a while since I last visited CF, but I'm finally back and, for the life of me, am drawing a total blank on something that seems like it should be fairly easy to handle.
The Math.sqrt() function works just fine if all a person needs is the Square Root of a number, but what about needing the Cube Root or even a 4th Root of a number?
My first instinct was to use the Math.pow(x,y) function with a negative value for "y." For instance;
var z=Math.pow(27,-3)
This should return a value of 3. Unfortunately, this doesnt seem to work when I tested it through the W3 reference pages, so I am looking for a clue as to how I might go about finding such values, or if it is even possible through Javascript.

calculating the summed values of a column. Also, the row values are subtracted from each other eg:
col1 col2 col3
row1 a b = a-b
row2 c d = c-d
row3 =a+c =b+d =a-b+(c-d)
however there can be N number of rows. I have listed below and example I have done to calculate the subtracted values but I am having difficulty doing the summations.
<table width="362" border="1">
<tr>
<td width="91"> <input name='r1c1' onblur='function update_Total_r1c()' size='6' value=""> r1c1</td>

What I'm trying to do, is to read a basic page on one domain with some text delimited by | symbols. I want to grab each chunk of data between the |'s and insert them into set points in a form on an entirely different domain. I have it setup to use PHP at the moment, but I'd much rather to do it with javascript if possible.So I'd have something like the following at http:[url].....
Code:
Bob|Fred|Tom
And the following page (at http://anotherdomain.com/form/ for example) would display that data as follows:
Code:

First part I'm banging my head against the wall on is about the amounts
of the Amount fields along the right to automatically equal the PETTY
CASH SUB-TOTAL field. So, the amount in this PETTY CASH SUB-TOTAL
field comes up automatically. Also, I need to have the amount in the
TOTAL AMOUNT field come up automatically as being the sum of the PETTY
CASH SUB-TOTAL and the PER DIEM SUB-TOTAL fields. Please see the
following as an HTML document to see what I'm talking about......

I have a script that calculates the $ amount when someone enters a number. For example, if you enter 2, it's $200 if you enter 3 the total is $300.I then have code that adds a $ amount based on a check box. So if check box is clicked it's supposed to add $10. All of this works, however, my last piece of code which combines the two totals isn't working right.1st of all, it doesn't display the total right away w/o checking the check box. That is, people should be able to just enter a 2 and go on with their business. Instead my code makes them check/then uncheck the box to see the total. I've posted the code below in chunksHere I calculate the TOTAL based on how many they selectCode:
function CalculateTotal(frm) {
var order_total = 0
// Run through all the form fields

My JavaScript knowledge is still at the beginner level. Struggling to get the final calculations for taxes in this form.
The form currently updates the Sub-total automatically when form selections are made. I also need the form to calculate the tax and total. The tax rate depends on the kind of shipping selected. For the first 2 options the rate is 13% for the 3rd it's 5%.
What do I need to do to get the final 2 calculations to work?
Here's the JavaScript from (mredkj.com):
Code:
function OrderForm(prefix, precision, firstChoice) {
this.prefix = prefix ? prefix : '';
// ****************************
// Configure here
// ****************************

I have a table that has a textfield for inputing numeric values. This field is in a repeated row table. The field id is 'amount'. I want to add all values in the text fields with ID 'amount' and display the sum in a textfield called 'totals' which is in a seperate table but in the same form. I have limited experience with jquery and I actually managed to create and delete a table row from reading posts on stack overflow. I tried using each() but it only works with the first row which is the default row.
$("#addrow").click(function(){
alert("It works.");
//$('#description tr:last').after('<tr>...</tr>');
$('#description tr:last').after('<tr><td align="center"><label for="description"></label><input name="description"type="text"style="background-color:#CCC;"
[Code].....
However as stated, It only works with the first default row that was loaded with the html. Values I input after adding a row using jquery doesn't get summed up.

I am trying to write a script that will take a date of birth and another date and, if the person was over 75 years old on the createdDate, return "true" (otherwise return "false").
Unfortunately my code doesn't seem to return either 'true' or 'false'!
The code is:
var dateofBirth="30/10/1982";
var createdDate="01/12/2010";
var sd = dateofBirth.split('/');
var dob = new Date(sd[2],sd[1],sd[0]);

I want to create a link that a user can click which will create a popup
telling the user their ip address. I have:
var ip = new java.net.InetAddress.getLocalHost().toString();
alert("Your IP address is: " + ip.substring(ip.indexOf("/")+1))
but this does not seem to work. It says the ip is 127.0.0.1. Strangely,
this piece of code used to work but all of a sudden it doesn't for some
unknown reason. Can anyone tell me what's wrong with the above code?

I have two date fields (check in, check out) and "number of days"
field.
I want the script to calculate automatically the difference.
For example: I have defaults dates, and I want the script to put the
difference in "number of days" field. And if the user will change the
date, the number of days will change automatically.

I am having difficulty getting the following assignment to run properly:Many companies charge a shipping and handling charge for purchases. Create a Web page that allows a user to enter a purchase price into a text box and includes a JavaScript function that calculates shipping and handling. Add functionality to the script that adds a minimum shipping and handling charge of $1.50 for any purchase that is less than or equal to $25.00.For any orders over $25.00, add 10% to the total purchase price for shipping and handling,but do not include the $1.50 minmum shipping and handling charge. The formula for calculating a percentage is price * percent / 100. For example, the formula for calculating 10% of a $50.00 purchase price is 50 * 10 / 100, which results in a shipping and handling charge of $5.00. After you determine the total cost of the order (purchase plus shipping and handling), display it in an alert dialog box. Save the document as CalcShipping.html.This is what I have after working on it round and round for 4 hours yesterday:

I am writing a form and doing a bunch of calculations one of which is a percentage based on the value selected. I am returning a correct result for two of the values but for the other two I am not.The 'discount' value is what I am looking for. It should return as 0 for values of 1 but it is doing the math as though it is multiplying by 1. And again for the value of 6 it should be 10% but is taking the value as 4.6 or something.Code is below I've included all of it (sorry) for better ease of understanding the math that is happening:
HTML Code:
<form id="form1" action="" method="get">
