How should I define two dimensional arrays in javascript?
Im unsure if the following code is okay...
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:
I am having serious problems over a JavaScript function. I have 2 x 2 dimensional arrays of data to display on the screen, each array being 18 x 18. The arrays and displaying them is working fine, I have 2 lots of X and Y variable (LocX1, LocY1, LocX2 and LocY2) which I use to reference the cells of the arrays.
I have 2 similar (but not identical) functions to move around these arrays using links on the screen.
[Code]...
As you can see, I have tried multiplying the variable by 1, adding zero and using the Number command. All other directions work fine and all links are identical, just passing a different 'direction' through an onClick.
P.s. I miss placed this post before, and it was sugested I re-check the links that set the functions off. They are all identical (all 8), except for the 'north' 'south' etc. bit.
I have the following array structure code...
Is it possible to sort this array not only by the first (DVD title), but also by the other (eg label. release date, etc.) elements?
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
[Code]....
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:
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:

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?
I'm sure this is a simple matter, but i cant seem to work out how to loop through a multi dimensional JSON object (where the keys are unknown). [code]...
View 1 Replies View RelatedI'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:
Â
var data = {
label: $('#label').val(),
child_float: function() {

.. 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?

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.
What is the correct syntax for multi-dimensional array? an array of arrays. I have an array such as code...
View 2 Replies View Relatedin 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

View 1 Replies View RelatedI 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?
View 1 Replies View RelatedI 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

View 4 Replies View RelatedFirst of all I need to define an array of 3 elements. Each element is associated with a different first name. Then I shall realize a first function to add a name in the table. The function takes as parameter the table previously created and return it containing an additional element whose value is the name that the visitor wants to add. I must use the dialog box prompt so that the user can specify the name he wishes to add in the table.
I shall also perform a second function which will display the name that is included in the different array elements. This function will also take the table in parameters and proceed with setting the display name with a dialog box alert type that contains all of the name separated by ";".

How is it possible to define a constant in a virtual class?
E.g. I wrote the following code
tml = {
sayHello : function()
{
alert('hello');
}}
now if I want to add a constant into tml virtual class, what I need to
do?
I tried something like
tml = {
const1 : Integer = 0,
sayHello : function()
or
tml = {
const1 : function(){return 0;},
sayHello : function()
in both case, trying to get - inside tml object - the value of
const1 ... it results in a Object value and not the Integer value I
need.

$(document).ready(function() {
$("#form1").validate( {
