I believe that this has been answered somewhere but I cannot find it. I have 51 textboxes on page. In 50 I can enter value. 51st should tell me what is average of entered numbers.
As user types I want script to iterate trough form count and sum non-empty fields and than divides this two numbers.I need to sum values from fields that have value (not emty fields) and to divide this number by number of non empty fields. This should occur on every change in any of those 50 textboxes so to have live preview of average.
I'm really new to JS and I don't know even how to sum these numbers.

I want to add onto my ebay auction a calculation which would show the unit price of a box of 5 electrical sockets.
So say it is currently on auction at £5.62 and I charge £1.99 Postage & packing thats a total of £7.61 with a unit price of £1.52. Then £1.52 is the figure I want to output and show on screen.
I'm just starting out in JS and would like to know how to solve this. I have an HTML form with 3 checkboxes, like a would-be order form. For example, on checkbox 1, the product is a toy car that costs $5.00, second box is a cigar cutter for $50, etc. I to have a button that when clicked, enters the total price (no taxes or subtotals) into a textbox field below in the same page.
In the second page he need to choose the time he want for his appointment (the time is in GMT+3 -> my local time). in this page the script also get the time zone and the date that he choose in the previous page (using POST - PHP). the date saved in variable. I used unix time (MKTIME function) I want that every time my visitor choose time (from drop-down box) a new cell/DIV will appear with his local time.for example - when he choose date: 10 May 2010, time zone: Austrlia - East Coast (+8 Hours) and time 22:00, New DIV will appear with the date "11 May 2010, 03:00AM" (there are 5 hours different).what is the JS what caculate and show the visitor local time?(I have, in PHP, only his time zone and the date that he coose in the first page)
I'm working on creating a custom calculator to determine the amount of money / credits users may earn from referrals. I've tested onChange, and it will work only when I have changed to a new field or clicked off that field. How do I make this calculate live?
So if the current value is 5 and I change it to 6, it will automatically recalculate the new value.
You can see what I'm working on here:

Note: The one I'm testing is the 1st Level field. For now i'm just having it display the date.
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 want to have 1 option box with values 10 100 1000 10000 etc in it , then i want to be able to select eg 100 and underneath it will show 100x25 which would be 2,500 so i want 1 box that has values of ten , hundred , thousand etc and they multiply by 25 and show underneath .
I have 3 textbox controls on my web page that are numeric currency fields in which a user can enter a numeric value, either positive or negative into TB1 and TB2 (both of these fields go thru edit checks to make sure a numeric value is entered and then return a currency value ie; $2500.00). TB3 is calculated resulting in TB3 = TB1 (($6500)) - TB2 ($2500).
My problem is that if a user enters a negative value for TB1, it returns a "NaN" and the value in TB3 turns out to be the same value as in TB2. Essentialy the calulation ends up being 0 - 2500 = 2500 (see screenshot). I've attached 2 functions below.
Code: function cal_Overage_Shortage() { if (make2Number("TB_LowPoint") <= 0) { document.getElementById("TB_OverageShortage").value = GetValueTextbox("TB_LowPoint") + GetValueTextbox("TB_RequestedLowPoint");

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.)

This does calculate what I need but only if I have up to two rows. I need to make the function dynamically count how many rows there are, and calculate the linetotal for each row. And here's where my limited JS knowledge brings me to a halt.I have been thinking about what this new and dynamic function should look like, but that's the best I could produce...

I am trying to calculate age based on the date of birth input into a text field. the date field should allow users to enter a one or two digit month, one or two digit date and a two or four digit year. Users should be able to enter any of the following date formats: 11-2-10, 1-25-2010, or 01/25/2010. On some days it works and others it wont, like 11-1-91 returns that the user is under 18.
function checkAge(){ var stDate = document.getElementById("birth").value; var dayPartToDate = parseInt(stDate.substring(0,2),10); var monPartToDate = parseInt(stDate.substring(3,5),10);

Calculating the difference between two dates in JavaScript is relatively straightforward, provided you choose the right Date methods to work with. Whichever way you get there. code...
I want to calculate the percentage of a number, but I'm getting a really weird result. In the following code f is equal to 3 and x.length is equal to 8. The part that isn't working is emphasised in bold. Basically 3/8 * 100 should result in 37.5 but the result I am getting with the following code is 7934570.3125. How do you calculate this percentage in Javascript?
