Recently I decided to branch out and learn some Javascript on my own. I'm getting the following error: Uncaught ReferenceError: array is not defined
I don't quite understand why I'm getting this error, as I've created the array in the function showPrompt and it seems as though it's being passed around correctly. However, I believe the problem is with generateBoxes, specifically this part here:
onclick=\"getValue(array, i)\"
(line 39)
Removing array from the function parameter seems to make it execute, but beyond that, i'm lost to what is wrong.
Here's the code:
function showPrompt () {
Obtains user input
var array = new Array();
var box = prompt("Please enter number of boxes","1");

I'm trying to trap a user entry that cannot be found in the database. When a code is entered, the page should give a "Code Not Found" message if it is an undefined value.
However, it didn't; and it always shows the "undefined" value to the page instead.
Here's what I actually did:
getting user input:
Finding the code:
I totally understand that in order to learn javascript I need to know how functions work, I understand the basics of passing in parameters and then calling the function with the values to maybe add something together etc I ve read countless articles about functions as well as books etc but I just dont get how they are used and when they should be used etc, the more advanced functions that have maybe 4 parameters and are doing different calculations and returning various values that get fired back into the script just totally confuses me.
What I would like to know is first of all how can I overcome this confusion and also any words of wisdom you may have. I will also add that I have no prior programming experience and have spent the last 2 months frequently hitting my head off a brick wall as I just cant understand javascript.
To formulate the problem simple i have two buttons with the onclick function:
I guess what im asking is how can you set a variable by one onclick function and then use it in any other function?
I am working on a simple Expanding Family Tree.
There are two principal Objects: Person and Family,
and two subsidiary ones: Sibling-sets and multi-Marriage-sets.
When I click on a Family Button, I want to display all the Persons
of a Sibling-set.
Married Siblings will have a Button. Pressing this should display
one or more Marriage-Partners. If these Marriages (Families)
have children, they will have a Family-Button.
You will notice the code for the four objects is fairly repetitious,
but that for the variable-length Sibling and Marriage Arrays,
is what has kept me struggling for days.
Lines S04-S10 and M04-M10 appear to be the problems.
Even though I think addSibling() is constructing Sibling objects,
S06 reads the Argument vector as a single item
S07 tells me the argument-count is 1.
so S09 processes only once, and then..
it interprets argv[s] as a single item,
but assigns the whole array to this.sibA.
Can anyone tell me what I am doing wrong? Code:
Say I have the following code:
And I want this code to print 21.
How should I implement the function Curry?

I'm new here, and new to js. Here is my problem: I have written out a code to make an image switch from state 0 to 1 and back to 0 again (an eye blink). The code works fine, but I would like to write the functions with arguments so it could be applied to more images. I have tried for a few hours (and searched forums) and am getting no where. Here's my code.
Code:
function home_blinkDown()
{
//alert('blink down');
var t = setTimeout("home_blinkSwap('home_js', 'images/main/home_blink.png')", 2000);

I am writing a small module which will have several different aspects to it, all based around ajax calls. I want to allow the main ajax functions i.e beforeSend, success, complete etc (I am using jQuery) to be customizeable.I currently have an options object in the module which can be extended with an options object passed to an init function. In here, I am passing a 'callbacks' object with nested ojects for each different type of action as in...
var insertCallbacks = {
before : function() {
},
success : function() {
[code]....
for some time I always found a workaround for this kind of problem. But somwhow, it feels wrong. So I'd like to know, if there's a common way to solve something like this[code]...
I'm defining the function and if the value of 'obj' hasn't until the function really gets called, this can work. But it just feels so wrong do have always global variables just to access them inside of a callback.[code]...
I would like to call a function with parameters, i.e. multiply('2','3','box1').In this example, the first argument would be multiplied with the second and written into the div with the id="box1". How can I set a default value for the third argument? => so if I call multiply('2','3') then it should automatically set the output-variable to 'box1' if not other defined in the call.

I have a parent page who allows user to view an invoice for service. My page bases the date and the value for payment to <%now%> and to <%total_price%>.
However I'd like to permit for users to editing those two fields by opeing a popup window with a new form and asking for these two new inputs. Afterward off corse, this values need to populate the equivalent fields on the parent page.
My questions:
1)I'm opening the new window after a js confirm instead of href or onclick methods, so I don't know how to pass the parent variable ID to the child window..
The code:
if (confirmation) {return true;}else{popupwindow("invoice_editing.asp?ID="id"");}
Problem:
the parentID=request.querystring ("ID") don't work
2)My child window picks the new values from the form... but I don know how to pass back the new values to the parent page and then reload it..
Please, but as much specific as you can to my problems and also please put the whole code of proposed solution, since I'm totally lost.
