Using A Loop Variable In Function Call?

Apr 6, 2011

i'm having trouble with some of my codes.i've been trying to put variables in function calls parameters, but it just does not work.
for example, if I try to do sth like this:

Code:
//a function that creates page numbers based on number of pictures that can be shown on the page
function MenuBar() {
pageSpan = [document.createElement('span')];[code]....

when i try to run it, it won't work.what i'm trying to do is that every time the loop runs, the "onclick" event of the created span will be the value of the loops "x" variable -1, and the value of x variable.meaning, for every new span, the parameters in the showImage() function are different.

Code:
pageSpan[1].onclick = function () { showImages(0, 1) };
pageSpan[2].onclick = function () { showImages(1, 2) };
pageSpan[3].onclick = function () { showImages(2, 3) };
pageSpan[4].onclick = function () { showImages(3, 4) };
pageSpan[5].onclick = function () { showImages(4, 5) };

Adding Total Value Of Combined Products?

Feb 18, 2011

I have a program that allows the user to input a product number from 1 to 5, and the amount of each product number sold. After all values are added, the program is supposed to calculate each product's total retail value, as well as the total retail value of all five products combined. The program runs fine, up until the end. I got all my alert boxes working, and the program is doing the multiplication as it is supposed to. However, when I get to the end, I receive "Last weeks total retail sales are: $NaN".

My code:
var productNum;
var quantity;
var prodPrice1 = 2.98;
var prodPrice2 = 4.50;
var prodPrice3 = 9.98;
var prodPrice4 = 4.49;
var prodPrice5 = 6.87;
var total1;
var total2;
var total3;
var total4;
var total5;
productNum = window.prompt( "Enter a Product Number (1,2,3,4,5):", "1" );
quantity1 = window.prompt( "Enter the quantity sold" );
productNum = window.prompt( "Enter a Product Number (1,2,3,4,5):", "1" );
quantity2 = window.prompt( "Enter the quantity sold" );
productNum = window.prompt( "Enter a Product Number (1,2,3,4,5):", "1" );
quantity3 = window.prompt( "Enter the quantity sold" );
productNum = window.prompt( "Enter a Product Number (1,2,3,4,5):", "1" );
quantity4 = window.prompt( "Enter the quantity sold" );
productNum = window.prompt( "Enter a Product Number (1,2,3,4,5):", "1" );
quantity5 = window.prompt( "Enter the quantity sold" );

total1 = document.writeln("Total for product 1 is $" + (prodPrice1 * quantity1) + "<br />");
total2 = document.writeln("Total for product 2 is $" + (prodPrice2 * quantity2) + "<br />");
total3 = document.writeln("Total for product 3 is $" + (prodPrice3 * quantity3) + "<br />");
total4 = document.writeln("Total for product 4 is $" + (prodPrice4 * quantity4) + "<br />");
total5 = document.writeln("Total for product 5 is $" + (prodPrice5 * quantity5) + "<br />");
document.writeln( "<h1>Last weeks total retail sales are: $" + ( total1 + total2 + total3 + total4 + total5) + "</h1>" );

Declare A Variable Inside A Function - Returns White Space - Not Variable Value

Aug 17, 2010

I am trying to declare a variable inside a function and use it later on in my code... but it just already returns white space... i.e. not variable value. I am setting it within this function:

function show_video1(){
document.getElementById('video1').style.display="block";
var video1Name = "Education World News (Part 1)";
document.getElementById('video2').style.display="none";
document.getElementById('video3').style.display="none";
document.getElementById('video4').style.display="none";
[Code]...

and trying to call it later on with this: <script type="text/javascript">document.write(video1Name)</script> It might be worth noting that each one of my 11 videos will hace a different name.

JQuery :: Form Validation Combined With Ajax

Apr 12, 2011

I'm trying to make a username form validation combined with ajax but I'm stuck at 1 point. I need to use a var that is outside of my $.get() function so that I can add the function to the validate plugin.

This is what I have:

As you can see, I'm trying to change the value of "var result" to true, but since that is outside of my $.get() it doesn't seem to happen. I tried to put the return command inside the $.get function, but then my validator always keep saying it's a false check.

Is there anyway I can call that var inside my $.get function?

Calculate Combined Value Of Html Fields, Printing Value To Another

Jan 29, 2010

I have a few html fields in a form that use PHP in order to calculate a combined value and then inserting it into the database. However, I would want that value to be displayed to the user as well before they insert it, just so they can verify that the value is correct. But how do I go about and do this?

It is probably very simple, but I'm a PHP programmer and have very little knowledge of JavaScript. Basically this is what I would want:

<field 1> -20 +(or -, depending on user input) <field 2>
Result of that to be displayed in <field 3>

However, I only want the -20 to calculated when something is entered in <field 1> so that it does not say -20 in the output field before the user even started typing a value.

Using Onchange To Call PHP Include And Set Php Variable?

May 14, 2010

I'm building a form in PHP. One of the fields needs to generate information based on another selected input. The first input is for "phase" and based on that I need to count how many entries there are in the database for that phase, then display posible positions(ie 1 per entry including the entry being edited/added). I know that this can't be done with only PHP.

I don't work with Javascript normally so I am struggling. I have read many similar topics, but can't find the answer I am looking for.

I thought that the solution could be to call an include file when a selection for phase is made, but I don't know how to pass the information to the PHP script.

I'd prefer not to have to reload the page or form.

Here's the code that I have so far:

Code:

<html>
<head>
<body>
<form action="edit-category.php?id=<?php echo $id; ?>" method="post"

Call A Variable From Pieced Together String?

Jun 23, 2011

I'm sure it's just a syntax problem. You can ignore most of this function because most of it works. The part I'm asking about is the "coordinates" variable 4th line from the bottom. The "office3" variable is a dynamically populated office number. I have the office numbers all defined as variables somewhere else but since I can't just name the variables as numbers I had to put a $ in front of them. Basically I'm trying to call the office number variable, $1656 for example. So "coordinates" is meant to be equal to "$+the chosen office number".[code]...

JQuery :: Create A Fadein / Out Between Images Combined With JCarousel Lite?

Dec 26, 2010

I'm not very experienced with jQuery yet and after a while of trying and searching I decided to ask for help here:

I'm using jCarousel Lite, the "Custom Widget" scenario (click in the list on the left)[url]

When clicking on a image in the carousel, the larger image is shown immedeately. I'm trying to achieve a fadeout, fadein effect. Doesn't need to be a crossfade, a fade out to white, fade in from white is fine.

My 'bare' code (this works, with instant showing of pictures, without any fades)[code]...
