Sorting A Two-dimensional Array

Oct 12, 2010

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

Code:
var myArray = [];
myArray[0] = [];
myArray[1] = [];

So now the first dimension will have a size of two (0 or 1) and the second dimension will have an unlimited size. I want to sort this array by the integer values held in myArray[1][x], where x is any number between zero and the size of my result set. That is, I want to reorder the array such that

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:

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?

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 - 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

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

Sorting Objects Inside Of Multidiminsional Array For Main Array?

Apr 25, 2011

I am really hoping someone is willing to take the time to read this post and take a minute to take a look at my code. What is happening is there are some matches for a script I made and then an area for segments during an event. If you notice on the segment part of the form is that there is a dropdown that asks for where in the event that segment needs to go. With the Introduction or the different numbered matches. What I need to happen for a subArray I need it to take the introduction, all the matches, and all the segments and order them accordingly. With the introduction first, the matches in order based off there match number and then the segments in between the introduction or matches based off the user's input.[URL]..

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

Sorting An Array Of Scores?

Nov 7, 2010

For example if I have this function name: function sortScores(myscores){ I would like to take an array of score records (each containing a score and a page number) and return a sorted version where the records are arranged in descending order of score.

so if I have this example call: sortScores( [ { score:0, Number:0 }, { score:2, Number:1 }, { score:1, NUmber:2 } ] )

I would get the example result:[ { score:2, Number:1 }, { score:1, Number:2 }, { score:0, Number:0 } ]

Where the results have been sorts in descending order of score. I've looked at this example, but it only deals with one one value -->[URL]..

Sorting Array Against Other Array

Jan 17, 2007

Say I have two arrays with the same number of elements that are related:

var a1 = [1,3,2];
var b2 = ["a","b","c"];

I need to sort a1 but have the order of the elements in b2 reflect the
any new order in a1. So if a1 sorts as

[1,2,3] then b2 becomes
["a","c","b"]

or if a1 sorts as

[3,2,1] then b2 becomes
["b","c","a"]

Sorting An Array Of Records By Value Of Field In Records?

Nov 2, 2009

I have written this program:

var scores=[];
function sortScores(scoreRecs){
for(i=0;i<scoreRecs.length;i++)

[code]...

to take an array of variables in calling the function (ie sortScores), place these variables into an empty array("scores"), apply the bubble sort to scores, and then alert scores in sorted form. When I use test values like I have above, where they are all just numbers, this program works perfectly and alerts the "scores" array, correctly sorted. However, what I would like to do is to call the function with an array of records, each containing two fields, and apply the same sort to the array of records, based on the value in the first field of each record.To illustrate, i'd like to be able to call the function thus:

sortScores([{score:0,index:0},{score:2, index:1},{score:1,index:2}]);

and for it to sort the records in descending order of the value of the "score" field. So the above call would alert:

[{score:2,index:1},{score:1,index:2},{score:0,index:0}]

however, i'm not sure how i'd reference the numeric part of the f1 of each record in the sort?

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:
