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

Dec 17, 2009

in PHP I can create a multi-dimensional array with strings for keys,eg

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

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

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

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

Create A Multi-dimensional Associative Array?

May 21, 2010

I'm trying to create a multi-dimensional associative array that has some of its data created dynamically. The code I've currently got is as follows (using JQuery to retrieve form element values):

Code JavaScript:
 
var data = {
label: $('#label').val(),
child_float: function() {

[code]....

.. if its values were not being created dynamically. However as you can tell that isn't what is being generated at the moment, as there's no opening/closing brace before/after the child_float's member variables. Any ideas what changes I need to make in order make the child_float behave as intended?

PHP Looping To Create Multi-dimensional Variable

Jan 19, 2010

PHP Code:

<script type="text/javascript" src="sylvester.js"></script>
<script type="text/javascript">
var M = $M([
<?php

[Code].....

I need to build a 100x100 array. I'm using the sylvester plug-in to make a matrix. The code executes fine and when i go view source from the browser the 100 rows and columns are defined just fine. I think that the document is first loaded then the php loops are executed on the server. Is there any way i can load a multi-dimensional array with PHP. I must do it that way, cause later i'll need to query the databases in the loops above.

Incrementing A Multi-Dimensional Array

Jul 27, 2005

I'm kind of at a lose this is my first foray into using a multi-dimensional
array and I've run into a snag. for some reason the second dimension always
seems to end up being the last value of the second dimension of the array
ie: in the case below the conditionArray[[0][1]] always ends up being 6.0
where it should be 1.0. Code:

Re-organizing Multi-dimensional Array?

Oct 30, 2009

Short version: I'm having trouble with "moving subarrays" in a multidimensional associative array.

Long version: (Yes, I know that there's technically no such thing as a js associative array and that I'm actually using a generic object.) This is one of those annoying questions for which significant code can't be shown.

I'm fetching a JSON object from PHP and parsing it as multi-dimensional associative array that comes out with this "structure": obj[regions][variables][years] = value; My presentation logic works fine for that. Year data is presented for each variable, and variables are grouped by region. For reference, if needed, the display is tabular and similar to this:

Passing A Multi-dimensional Javascript Array Through A Form

Mar 11, 2005

I would like to be able to pass a multi-dimensional Javascript array through a form to a server-side script I am running. Any suggestions as to how to do this? I know how to asign a Javascript variable to a hidden field (basic stuff ), and if it was a single-dimension array I would join() it, but I don't know how to treat a multi-dimensional array. Any suggestions?

Matrix Woes - Summing Up A Multi-dimensional Array

Sep 27, 2011

I have a Javascript array object like this:

[0][0] - 32[1] - 13[2] - 26[1][0] - 8[1] - 17[2] - 4[2][0] - 10[1] - 30[2] - 22...etc

and what I want to end up is with an array with the sum of the [0], [1] and [2] values, so for instance with this example, I want an array returned like this:

[50, 60, 52] i.e. this is [(32+8+10), (13+17+30), (26+4+22)]

My real problem with this is that the "inner array" can be any number of (its dynamic), so in my example its just 3 values but it could be for example 5 values e.g.:

[0][0] - 32[1] - 13[2] - 26[3] - 16[4] - 6etc

Multi-dimensional Arrays With Image Rollovers

Aug 9, 2006

I'm trying to get rollover images to work that are a little more complex than usual. I have a webpage that presently gives information on four groups within an organization. I've put each group within its own div with an id. The div contains a short description of what the group does, thumbnails pictures of each member of the group, and to the right of these thumbnails, a larger picture. This larger picture is supposed to change, when ever the mouse is over a thumbnail to a normal size picture of the thumbnail, for the first part.

I tried to put in a script that will preload all the original images that should be changed. First I created an array with all the names of the divs, then used two for loops, one nested inside the other to get the pictures into the array. Tried to get the names of the array to hold the pictures from the first array with the names (inames), using a two dimensional array (used an example from a post on this forum) but it seemed to have gone astray, as the onmouseover doesn't work. Code:

Sorting A Two-dimensional Array

Oct 12, 2010

I am declaring a 2D array like this...

Problem Using GetElementsByName On 2 Dimensional Array In IE

Aug 17, 2007

How can I fetch a part of the array in IE?

The code works as expected in Opera and Firefox, but IE returns an error saying that matchPaid does not contain a value.

As it seems IE does not pull any of the input fields belonging in the array.

I believe the issue lies in this line:

var matchPaid = document.getElementsByName("plan_bonus_amount["+key+"][]");

The rest of the function:

JavaScript Code:

function updateMatchPowerline(total, newPlan) {
var totalPlan = parseInt(document.getElementById("total_plans").value);
var totalMatch = document.getElementById("total_match");

if (newPlan === true) totalPlans = totalPlan + 1;
else totalPlans = totalPlan;

var matchValue = 0;

for (var key=0;key < totalPlans;key++) {
var div = document.getElementById("match_table_"+key);
var newTbody = document.createElement("tbody");

var match = new Array();

if (key < totalPlan && parseInt(totalMatch.value) > 0) {
/*Fetch the current values, then clear the table*/
var matchPaid = document.getElementsByName("plan_bonus_amount["+key+"][]");

for (var nr=0;nr < parseInt(totalMatch.value);nr++) {
match[nr] = parseFloat(matchPaid[nr].value);
}

remove(div);
}

for (var nr=0;nr < total;nr++) {
if (typeof(match[nr]) != 'undefined') matchValue = match[nr];
else matchValue = 0;

newTbody = createMatchPowerline(newTbody, key, nr, matchValue);
}

div.appendChild(newTbody);
}

totalMatch.value = total;
}

Does anyone have an idea on how I can fetch those values in IE?

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?

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.

Assign Scores To Separate Strings In An Array?

Nov 4, 2009

I was working on this problem that asks me to return an array of scores for each string (only for its content part, not URL) in the global variable, which is an array. For example, alert a score of 0 if the string z is not found, 1 if found once, and 2 for twice. My problem is that I can get the code to alert if it has found the word (ex. "the"), but I cannot manage to :

a) Assign separate scores for each string.

b) Make the search case insensitive i.e. "the" will appear in 0,1, but not in 2, where it is capitalized

[CODE]
var c = ["[www.facebook.com] Facebook is the best social networking site to coccent with your friends. ", "[www.google.co.uk] Google is the worldwide search engine. ", "[www.bbc.co.uk] The best news source for starting your day. "];
function findScore(z) {
