User enters integer values into an editable gridview. JS is meant to keep a running total in the gridview footer template while user enters the values. User clicks 'Save' button. The values are saved to database table.
Problems:
1. JS does not keep a running total if there is already values saved in a database table. (Explaination: If user clicks 'select all', the previously added values are loaded. Can edit these and running total works. But, if user is entering numbers for the first time into a blank editable gridview, the js does not work).
2. Cannot access label in gridview footer template. 'Object reference not set to an instance of an object'. If label is placed in normal gridview row, it is fine. However, it needs to be in the footer.
javascript function
Meant to be in footer template but placed in normal row for now:
how would i display the numbers the user enters and display the average of their numbers?

I'm trying to set a cookie when a user enters a page. The cookie is for youtube to make videos default to widescreeen.
I know that the cookie name is wide, the value should be set to 1, the domain should be .youtube.com but I dont know how to do it properly. Ive been trying to set it from a link, so when a user clicks the link and it opens in a frame, the cookie is set so that the youtube video opens as widescreen in the frame.
however, whenever I look at my list of cookies, it isnt being created.
is this the best way to do this?
(I found how the cookie is created by checking the values of the cookies when I pressed the 'right turn' arrow on a youtube video)
I am trying to put up a page for my students for them to be able to enter

I am working on a online video portal build on flash/actionScript.
If I enter a url of a video when another video is playing, it doesn't playing the new video but it keeps on playing the old video. The reason I think is as it is a RIA, it doesn't refreshes the page and looks for a flash object and its already cached so it doesn't makes any http request in order to play the new video.
So I am planning to claer the cache.
how to clear the cache when a user enters something in address bar and press enter key?
So I decided on my midterm project its going to be a simple gas/trip calculator that calculates the cost of the trip with regards to price of gas an how many miles your going. I am just learning how to use the DOM so please be nice with me lol. Anyway I understand how to grab a field from a form an slap it into a variable but what i cant figure out is how to make the result appear in the result input field. So Here is my 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.)

I have a HTML form containing two text box controls in it and a submit button. When a user enters information in those two textboxes and click on submit, the information is sent to a function in Javascript. In the javascript, the information from those textboxes is stored in a javascript variable. The problem is as follows:When I am inputting string text in the html text boxes and in the javascript when I am trying to print those values, it is giving me out an error saying NaN. However when i input integer values in the text boxes it is printing those numbers. Is there a conversion that I have to do for the string to be printed. I am new to Javascript and need your help. This is a basic code of Javascript. Below is the code that I have.

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 .

Im wondering about how JavaScript does the following calculations to get those results? Please explain it if you do.
I am thinking of how to write the code for this:
There are 3 textboxes, each labeled:
TOTAL
rd_PROPERTY_VALUE
LTV
Both “TOTAL” and “rd_PROPERTY_VALUE” allow you to enter any number (e.g. 10000, 2500, 12345, 100.10, etc.). So whenever I enter numbers in both of them, the 3rd read-only textbox will automatically divide TOTAL by rd_PROPERTY_VALUE then times it by 100 and show the calculated value in the “LTV” field.
For instance it should mathematically appear like this:
(TOTAL / rd_PROPERTY_VALUE) * 100 = LTV
Can anyone give me any references to this?
need to calculate decimal values
example 42.925181855342466 + 58.64
but i get this $58.64$42.93, i know js is easy on int values
Code:
Esanda.prototype.calculateFornightCharge = function(payIndex,dueIndex)
{
var oThis = this;
alert("Pay index" + " " + payIndex + " " + "Due index" + " " + dueIndex);
var pi = (payIndex-1);

how to It calculates amount column value by multiplying quantity to amount.i.e. amount=qty*rate and gross total is sum of all the array elements in amount.Here I want to add two more columns viz vat% and vat amount.Simply it will be amount*vat% / 100.Can anyone please tell me how I can do that?Other thing is, is it possible to separate the 5% vat and 12.5% vat values and display the total of them in respective column?

I have a table which I have made work where I put some values in and the script works out the result on an onChange event.
My question is that I want to make the table rows populate from a database so each of the javascript values will have to be unique for the value to be worked out on a specific row calculation.
The code as it is works out the single value but how would i go about using the mechanics of the code to apply to multiple lines in the table. Code:
I have this code to get results based in search query.
<script type="text/javascript">
$(document).ready(function(){
$('#envio').click(function(){
var iURL = "http://ajax.googleapis.com/ajax/services/search/images";
[Code]....
This return a Object as you can see in images exposed at this URL: [URL]. My question is how I can get unescapedUrl value for each result? The $.each in the code before doesn't work as you can see in images too.
Can someone explain how I can use javascript (I am assuming this is the best
way to do it) to add two field values together. I.e. field 1 plus field 2
equals field 3 (this is in a php form)
Also how can I set a field to be a value depending on what the user selects,
i.e. they may have eight items to select from and each one has a different
value.
The above javascript will then use that value to add to another field value
to give a me a total value....
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.
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.

I have a form that gets values that a user has selected from a list menu field, that end up like this added to the URL:[url]
Instead of the Field being mentioned more than once, how can I have it where it could mention the field once with the values coma separated eg:[url]
Would I use JS to change the URL? or VBscript?
I need to have the user input 5 set of; miles, and gallons used to calculate mpg. Also need to total miles and gallons used. I have the array ok, but i cannot remember how to figure mpg for each array element. this is what i have. everything works execpt the mpg for each array element.

I am having trouble with figuring a way to set my loop up to reset values of the different coin values. Example, when I put in 78, and click calculate, it tells you how much of each coin would be given back. My problem is that I set it up and run it, but when I put different values in back to back to calculate, some of the fields don't reset.
var change_out = function(){
do {
var money = document.getElementById("cents").value;

I want to display three sets of images on a Web page, and I want to use only one jcarousel to do it. I want to change the list of images based on the user clicking on one of three links, each representing a set of images. How do I do this? I know I can edit the DOM to modify the list of items, but how do I call jcarousel's reload() function? I thought of using three instances of jcarousel, but that takes up too much screen space and requires the user to scroll too much.
