## Calculate Checkbox And Drop Down Values?

Oct 19, 2009

I have the following code working with the checkbox options but once I added a drop down menu with values, it doesn't calculate it. I've done some different things to try to add the drop down to the function but nothing would work that I've tried so far.

I have it setup so when a box is unchecked, that option is taken off the price, the drop down should do the same to switch between the options price.

## Combining Two Or More Text Drop Down Boxes To Calculate A Price?

Dec 13, 2011

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

## JQuery :: Null - Undefined - Empty - Drop Down Option Is Selected In A Drop Down List ?

Oct 25, 2011

I am asking jQuery to tell me which drop down option is selected in a drop down list - like this:

I would like to check if this was successful before I proceed. What are the possible return values for this statement?

If no id exists.
If no option is selected.
If some other problem occurred.

In these cases am I expecting a null return; an undefined return, a false return value?

And, based upon the complete set of return possibilities, what would be the best and most comprehensive tests I could apply to cover every base.

## Drag And Drop Breaks After First Drop?

Feb 20, 2011

So, what it does: You can successfully drag something anywhere, but when you click it again, it resets to its original position (I don't know why), and when you try to drag it again, as soon as your cursor touches the object it disappears (I don't know why). why it is happening and how to fix it!

// JavaScript Document
var posX;
var posY;
var element;

[Code]....

the html is a simple (position is set to relative):

<p id="square" onmousedown="drag(event)">meep</p>

EDIT: This is the first time I've written javascript code and would like to learn the basics, which is why I am not using a library.

## Turning Drop-down Menu Into Drop-up (or Both)?

Feb 1, 2010

I'm currently redesigning my site, and I have a small quandary.[URL].. Unfortunately, not everyone has the same size monitor as me, therefore sometimes the drop-down menus get cut off. Is there a way with this script for it to auto-detect if it's going past the bottom edge, and when this happens it'll go upwards instead?

<option value="calibration and repair">Calibration and Repair</option>
<option value="repair">Repair</option>

## Calculate While I Type

Jun 29, 2006

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.

## Calculate Once New Value Is Typed In?

Apr 8, 2011

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.

## How To Calculate Properly?

Feb 15, 2007

Can someone explain to me how I should code to calculate this?

## Calculate Each Row And Then Total

Jul 26, 2011

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();
?>

## Can't Calculate A Negative Value

Jul 19, 2011

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");
