Defining Array Elements With Keys

Mar 13, 2010

I would like to have an array and define which element goes to what key. Something like this:
Code:
var test = [][];
test[0][0] = "foo";
test[0][1] = "bar";

However I am wondering if its possible to write it in one statement? Something like this:
Code:
var test[0] = [
[0] => "foo",
[1] => "bar"
];
The code up doesn't work of course.

Defining Pictures In An Array

Jun 15, 2006

I wish to access several pictures on my page by defining them as an array. This way I can either loop through them or access them by array index.

What I am really doing is writing my own picture gallery and slide show. The reason I am doing this is so that I can have my web page look exactly the way I want. In addition, it is an excellent way to learn Javascript.

Function Defining Index Of Array?

Mar 24, 2010

Code: function initArray() {
this.length = initArray.arguments.length;
for (var i = 0; i < this.length; i++) {[code].....

For the above piece of code, does the function 'function initArray()' just predefine the array that is written right after so that it's first array index starts at 1 instead of 0?

Sorting Array Changes Keys?

Jan 26, 2010

Firstly, apologies for my terrible JavaScript knowledge! I'm getting there! I have an array that is made up of the results of a few SQL queries. The queries return the record id and an integer. I need to sort the results of the queries by the integer. I am trying to store them in an array, using the record is as the key, then sorting the array. However, when I try to get the data out of the array, it has changed the key!

E.g.
Original results
[10605] = 141
[10744] = 116
[18835] = 166
[15304] = 166

Force Js Array Keys As String() Not Int()

Jul 8, 2011

Given a JavaScript "array" (ok, so really they are "objects" but it's being treated as an array...) in the format

HTML Code:
var patient_code = "0"
var header_id = "1";
var question_id = "1000";
fake_data_array["patients"][patient_code][header_id][question_id]
HTML Code:
var fake_data_array = new Array();
fake_data_array["heading_information"] = new Array();
[Code]...

What's happening is, '1000', '1001', '1003', '1004' are being cast as integers, not strings, and it's "filling in" the first ~999 keys as 'undefined' so the length is returning something like 1005, not 7. I'm manually writing the arrays now, and will eventually be building this massive js array from a collection of existing PHP arrays. Is there a way to forcibly cast the values as strings?

PHP - Create A Multi-dimensional Array With Strings For Keys

Dec 17, 2009

$arr['key'] = array("item 1","item 2");

This works if the string is a variable as well, like

I'm trying to something similar in javascript, but with no luck

Comparing Array Values To Select Unique Array Elements?

Apr 10, 2010

This one is throwing me off! Either I am making a stupid mistake or I'm doing it totally wrong I have an array, and I am trying to select unique values from it and assign it to another array. Here is the code:

Code:
var flag;
for (i=0;i<=pdfs.length-1;i++)
{
flag = 1;
for (j=0;j<=pdfs2.length-1;j++)

[Code]...

The problem is that the if (pdfs2[j] == pdfs[i]) statement ends up never being true. There are URL's to pdf files in the array. On the other side, if there is a much easier way to select unique values from an array, please feel free to point it out.

Shuffle Array Elements (3 To End Of Array) In Random Order

May 6, 2007

I'd like to reorganize the third, fourth, fifth and sixth, as well as any
elements thereafter in an array in random order:

var a = new Array('first','second','third','fourth','fifth','s ixth','etc')

In other words, the first, second and third element should remain in
position 0, 1 and 2, while the fourth, fifth and sixth, etc. should appear
in random order.

Using Form Elements In Array?

Sep 22, 2010

I am creating an array based on form elements. I then am trying to create an IF (and nested IF) statement to check if the fields are empty and then with the nested IF statement use certain fields to create mathematical functions.

So far I have this:

function QuantityMWh(form) {
var formchk = document.forms[0]
for (i = 0; i < formchk.elements.length; i++) {
if (formchk.elements[1].value == "" && formchk.elements[2].value == "") {

[Code]....

It's only checking the first field and not the second, and vice versa. i.e. if only one field has text then it passes.

Addition Of Elements In An Array

Aug 16, 2011

I am trying to add the elements in an array together and display the result, I am using a user prompt to obtain the elements for the array, this works fine but when I come to add the elements together and display the result all I get is a row of the elements not their sum. The user inputs are all integers (the program adds the prices of items together so they are all numbers,amounts). If the user enters 10, 15,15,20 the result I get is 10151520 not 60.
