Subtracting Values In A For Loop?
Dec 7, 2011
I am having difficulty with creating a function that uses a For Loop to pull in two unknown variables and subtracting the first number from the second number. The subtraction occurs but I always get a negative number. This exact same function works correctly when adding but does not when I use it for subtracting to values. Here is what I have so far:
function calcDep1()
{
dblTotal = 0.0
for (i=8;i<=9;i++)
[Code]....
I have worked with it for several hours and also changed the equation to reflect dblTotal = dblTotal - dblValue but it still evaluates to a negative number. The two test values I used are 100 - 50 which should equal 50 but the answer always comes out to -150.

I have a struct like this:
Code JavaScript:
function Sampe(name, value, unit)
{
this.name = name;
[code]...
I then have an array of instances of this struct. I'm trying to create a search feature and need to loop through each instance of the struct in my array. Then I need to loop through each value in the struct and check it for a substring. If a substring is found the entire struct instance is printed and the search will skip to the next struct instance. Right now my loops are not working properly. The loop below with 'item' is not correct as 'item' just prints out a number (should be a text value).
Code JavaScript:
function searchView(text)
{
document.getElementById("searchResult").innerHTML = "";
[code]....

I have a form with a lot's of number of Text and Hidden Fields. I just do a simple loop to get each value for each attribute. I have about more than 2000.
if i do something simple like :
for (var i=0; i<2000; i++)
aValue = i+10;
it runs well. But if i do something like
for (var i=0; i<2000; i++)
aValue = document.myForm.elements[i].value;
it gives me 100% CPU for a long time before i submit the form.

I have a bunch of input fields, each which will have a numerical value. There can be any number of input fields in the form, and that number will vary depending on what the user has selected prior in the application.
So basically I created a loop that goes though all of the INPUT fields within the form. How can I have it find the value of each field and add them all together, then return to me the total? It'll need to be made into a variable, but a simple alert with the total value will give me enough to work with.

How to subtract totalgift if my condition of donateamount is lesser than the totalgift trigger.
When the field is selected and the DonateAmount is trigger, I need to subtract the entered amount on the field selected to the TotalGift and put the field selected to zero "0" and TotalGift to original amount which is less than the amount entered on the field selected. I have some code that I created but it doesn't work. My initial javascript to calculate all the total is below assuming that DonateAmount is already selected = 25:
Below is what I am trying to do but it doesn't work. If the first input field is selected and user enter amount greater than the TotalGift, alert will pop-up then and the amount entered by the user automatically added to the TotalGift. So what I wanted to do is to subtract the amount entered to the TotalGift so it will go back to the original amount before the addition occurs. I know it is possible but I just can't get the right code.
My html code below which I have 18 input fields but all of them only optional wherever the user wants to input number. I will only include some here. Code below works, please ignore any missing code. I just need the calculation code to work.

Having a small problem with writing out the matches from an array using a For loop.
I have two arrays, lets say arrayA and arrayB. In arrayB are numbers which are a number of miles, ie 1,2,6,4,5,6,6. And in arrayA are the days of the week. Each day of the week is associated with a mileage, ie Mon = 1, Tues = 2 etc.
My script has found the largest mileage in arrayB. Next I have to find the days of the week that match this highest mileage and write these out, along the lines of "The highest mileage was 6 run on Wed, Sat, Sun."
I have managed to get a For loop to work with this BUT..... I can only get it to write out the first instance of the day the match is found. ie "The highest mileage was 6 run on Wed,"
[CODE]
maximumDistanceIndex = 0;
for (var distance = 1; distance < distanceArray.length; distance = distance + 1)
{

The Script below generates a sudoku (9 by 9) table and displays the table on screen.
what I am trying to do is to get a string of numbers entered into the text field labeled "enter values" on the page below the table, into each cell box of the sudoku table when the button labelled "load" is pressed. This would fill the sudoku table with characters, one character (from the text field) to each of cell boxes in the sudoku table.
It requires using a for loop, I tried using one in my function (g) but it doesn't work,..

<title>Sudoku</title>

I am taking a js class and there is one minor bug that is driving me crazy with this assignment.
First, here is the code I wrote, then my question:
var games = ["Jacks","Chutes and Ladders","Extreme Uno","Bopit","Barbie Doll"];
var price = [4.00,15.99,25.00,27.99,32.00];
var inventory = [40,15,30,20,40];
[Code.....
I can't (just before this line) assign 0 to each array item - to get it defined because if the user goes back in and adds more, it will always reset the number back to 0, which is not what I wanted.
I tried adding an if..else statement instead, but cannot figure out how to get that to work?

I'm trying to create a short, html/javascript mario text game. Now, in the beginning, he fights a goomba.
He has a health and energy number as variables:
And then, there will be different buttons for different attacks. However, the only one created is "Punch", with this code:
What would I put in the onClick function to make it subtract 4 health from the goomba and 2 health from Mario.

Putting some javascript into a pdf file and can't get this to work out right.
Basic setup:
Field X = checkbox;
Field Y = numeric input field;
Here's what should happen (increment is toggled):
Y has a value. When X is checked, Y is increased by 5. When X is unchecked, Y goes back to its original, unmodified value.
Here's what really happens (increment is subtracted):
Y has a value. When X is checked, Y is reduced by 5. When X is unchecked, Y is reduced by 5 again. Anytime X is clicked on, Y is reduced by 5 yet again.
Here's the code:

I have been looking at this code for two evenings now, and rewrote it 4 times already. It started out as jQuery code and now it's just concatenating strings together.
What I'm trying to do: Build a menu/outline using unordered lists from a multidimensional array.
What is happening: Inside the buildMenuHTML function, if I call buildMenuHTML, the for loop only happens once (i.e. only for 'i' having a value of '0'.) If I comment out the call to itself, it goes through the for loop all 3 times, but obviously the submenus are not created.
Here is the test object:
test = [
{
"name" : "Menu 1",
"url" : "menu1.html",
"submenu" : [
[Code].....
'Menu 2' and 'Menu 3' don't show up! I'm sure it's something small that I'm overlooking.

I'm looking to send a loop variable (i) to a function inside the loop, but I can't seem to get it to use the value I want, it keeps making it a reference of i and therefore the function is always called using the last value of i rather than the one it was set with.
So if i have 5 Tabs then Tab 1, when clicked, should call DefaultTabClick(0) and so on rather than always using 4 for any of the tabs.

I am doing some studying and we was to create a small loop using either the for loop, while loop or do while loop. I chose to do the for loop because it was easier to understand, but I want to know how to do the same using the while loop. Here is the for loop I have, but I cant figure out how to change to while loop.
for (var i = 0; i < 5; ++i)
{
for (var j = i; j < 5; ++j)
{
[Code]....
How do you make the same using a while loop?

I have a list of products where they have minimum quantities in a hidden input. Some products have multiple colours, though the same minimum quantity and I'm trying to implement a jQuery check that entries made are at least equal to the minimum.
Blank or '0' entries are fine but if it's below the minimum quantity it should set to the minimum.
HTML:
Is there something obviously wrong with this? It isn't performing the minimum check and I'm really not sure why.

In part of my form, I have 3 inputs (one textarea and two text inputs),I am validating their value format using AJAX (each input triggers error message on its label in case format is wrong). Also I have one button, "NOT submit button" (type = button).Now, when clicking on the button it must enter the value of those three inputs in my database in case they are true then all inputs values must be cleared. In case AJAX validation is wrong and in case the user clicked on that button, the value of fields must kept as it is.
Actually I can not use submit button because I have it for the whole form and what I am taking about is a part of the form and it's not possible to make nested forms as I know it violates html rules. It's easy to make it if I am taking about submitting button as I can view session values on fields after submission in case ajax returns error.I can clear inputs from Javascript, but it will be cleared on both cases if AJAX validation true or wrong. Each input field has AJAX Error message that will be triggered when the input format is wrong.

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 built my company's website and the content portion of the site uses
text with styles with relative values and the navigational part of the
site uses text with styles with absolute values. The purpose of this
was so that the end user could increase the size of the text on the
webpage and only the content portion of the page would scale or resize
but the navigation would not. This works as expected on a pc but the
entire page scales on a MAC. Does MAC not support text with styles the
same as pc so that the only scalable text is that with relative values
(ie: small, x-small, medium, large, etc)? Absolute values conist of
point sized text. Code:
