Passing An Array Of Arrays To Function
Nov 8, 2010
I was having some trouble with 2D arrays (or array of arrays). Essentially, the array has 100 rows, with two columns. The first column of every row holds a name, and the second holds a sales amount. With the use of a do while loop, the user can continuously add up to 100 names and sales amounts. After all the information the user wishes to add is stored into the 2D array I'm attempting to pass that very same 2D array as a parameter to a function called printRow as can be seen in the code below: Note: the function call and the actual function are found in two separate javascripts.

im trying to take an array and create a new array in a function to have it be used in the calculation function. I keep getting undefined when trying to output it. I can pass it directly using Spec(skills, spec, train); inside the function but that defeats the purpose of the function since its not always going to be used.
ive looked for hours on google and its all just variables which i can work fine but for this it will not work.
function Aluvian(){
document.ACCalculator.skillcredits.value = 100;
var skills = new Array();
var spec = new Array();

I would like to pass an array to a function but how does the program know which array I would like to choose from?? Lets say I have 3 arrays and I would like to pass array C, to my function. I checked the web but they only show if you have ONLY 1 array but NOT for multiple arrays. How would I even go about doing this??

I'm having trouble passing data in an array to a javascript function. I dynamically create a list with edit links on each row and pass the array to the function on each link. Of course, the function only gets the data from the last row, regardless of which link is pressed. Here's the code:

why this code works in FF, but fails in MSIE? In particular the content / display of the <select> options.
What is different in the executions of the same script on different browsers?
What can I do or change to make it work in both browsers?
Code:
<html>
<head>
<title> Pass array by reference </title>
<script type="text/javascript">

is this correct
var mid = math.floor((0 + array.length)/2)
from here you could use array.slice to divide the array into two equal sized arrays?

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:

However, there is one problem that I just can not figure out. I have 3 arrays storing information on page1.htm, this is all well and good, but I want to use the data stored in those 3 arrays when the user moves to page2.htm.

This may be more of a Java question, but I feel that JavaScript experts
may be more qualified to help me find a solution.
In short: is it possible to call a Java method from JavaScript, passing
as an argument a JavaScript array (in my case, an array of doubles)?
Supposing I have array x containing only doubles, I have tried:
document.MyApplet.myMethod(x);
But the method only ever seems to receive "null" as an argument.
Conversely, if I try this with a String, or a single character, or
almost anything else, there isn't a problem. Any ideas?

I've been given two arrays:
arr1 = [1,8,9,12]
arr2 = [2,3,10,11,13]
My task was to merge the two arrays into a third array. Done, no problem, merged then sorted a new array. I understand there is a way to merge the two without using "merge" then "sort" functions. My reference material doesn't go into it, and I can't find an example of how this would work. I think there would be a way to do it using a for loop and then "push", but I could be way off.
Can anyone tell me how they could see merging two without using the merge then sort? And what would be the advantage to doing it this alternate way as opposed to using merge? Is there a case where it would be preferable? I'm so new at this that I can't fathom doing anything other than merge.

(the "code" below is pseudo code, just to get the idea across)
Here's what I currently have:
var bill = new array[20];
var sam = new array[20];
var nancy = new array[20];
var Oscar = new array[20];
I'm assigning objects to them (ie Oscar[5] = new objLabel() This seems like a kluge, however. Here's what I'd like (again, pseudo-code)
var Objects = {bill:null; sam:null; nancy:null; Oscar:null};
var theObject = new Array of Objects[20];
// yes: i know that's wrong... and that's the part I'm having trouble with
so that I can do something like:
[Code]....
Just seems to me that keeping a single array of multiple objects is likely to be less error-prone than multiple arrays of single objects... But I don't have the syntax right... or can it be done in JS? If it's doable, would someone be kind enough to show me how to declare and access that example?

I have a choice when creating a new API that I would like other peoples opinions on. Do I use a single Array or Multiple arrays such as: array[1][1] = "ID[56]NAME[Hello World]START[10]"; OR
ID[1][1] = 56;
Name[1][1] = "Hello World";
Start[1][1] = 20;
The API is used for animations so is very heavy work, but would using around 15 multidimensional arrays be too much and a single one be preferable???

I'm a JS beginner and I find looping through arrays with for/in is very easy. Yet I find lots of code examples where array length is used instead of for/in and I'm thinking to myself, why do it this (somewhat) hard(er) way?
