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?
View 1 RepliesI'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:

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:
Â
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?
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

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
I have a database which writes to a webpage. The html has one field showing called client_userid with an id of client (see below)
<tr><td>
<span id="client"><WebObject name=client_userid></WebObject></span>
</td></tr>
The value returned in the table is a 7 digit number eg: 1234567 This web view may have one, a few or a thousand records showing depending on the search criteria. For the life of me I cannot find a script that will pass all returned field values to an array that will allow me to remove duplicates and add a hotlink to the individual number and showing the result in a new view of the original table.
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 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:

<script type="text/javascript" src="sylvester.js"></script>

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.
I really want to use this (javascript, jquery, and css) menu at this web page: [URL]. However, I would like to have this menu as a multi level menu. Currently it is two level. How to make this menu as three or four level?
View 1 Replies View RelatedI would like to have a main form (written in PHP) that has a "lookup" button next to a text field. When the user clicks "lookup", it should open a new window that lets them search (child.page1). When they enter a name or DOB into the search form, it submits the form through PHP (via POST), to a results page (child.page2). This displays all persons in the database which have a name or DOB == to the search term(s), with a checkbox next to each match. They click the checkbox (or alternenatively, a link), and return the checkbox value to the main window.
I have everything working right now, except that (child.page2) doesn't recognize the main window. If the data is entered on (child.page1), it works fine. I'm not very familiar with javascript.. is this even possible? I've considered using frames, to keep the parent-child relationship evident to the computer, but figured I'd check to see if there's an easier way.
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

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 have a form that has been dynamically created from PHP. It is basically a calculator and the number of form elements as well as names of the elements can vary greatly.
I basically want to add a button that will open a new browser window with the form info being passed to it. Basically it will create a quotation for the customer that is suitable for printing.
The only way I know to do the popup window is with javascript (unless php can do it). I know how to access form elements with javascript if the form element exists, but given most of the elements may change, I do not know how to access them.
I have a section of javascript that declares a global variable for a few functions, like this incomplete code
Code:
The above, in its full version, changes the text in a textarea. In my php code, if I include the above code above the textarea, it all works as expected.
The problem is that I may have more than one textarea - the number cannot be known beforehand. If I include the above before each textarea, the pointer gets confused as to which string belongs to which textarea since the global variables get redefined many times. In php, this would be a simple problem to solve with a mutildimensional array but, from what I understand, javascript doesn't have such arrays.
Someone can provide a solution that will allow me to use the same block of code over and over in the same file.
Lets assume the following object
Code:
var x = {
y: {
z: 10
}
} ;
Next, I need to retrieve the value '10', but the only thing I have is one string as a key For example (this doesn't work):
Code:
var str = '[y][z]' ; // or 'y.z'??
alert(x[str]) ; // should alert 10
Can this be done using a single string as input for x ?
UPDATE: a solution which comes close to what I was looking for is
Code:
var str = "x['y']['z']" ;
alert(eval(str));
i wrote code below, but it always return -1,
var arr = {
11: {
2: 'value1',
3: 'value2'

I'm pretty new to Javascript and I'm trying to build a form which gives a configuration for a product. It consists of 5 drop down menus and each value in the drop down needs to have an image, a price, and a rule attached to it. The image sits above the drop down and changes with the selection, the price adds to the option prices selected in the other drop downs and give a total, and the rule affects what options are available in subsequent drop downs. I've got all of these working separately but can't get a single value to have all 3 functions.

I am just beginning to try to learn some js, and am making a site which requires a multi selection form with each being added up to reach a total. This sounds like a standard form, but this is a little different. I have files in megabyte sizes, from which people would choose what they wanted, and the total deciding how many dvds would be needed to store that many files...and this total could then be added to a js shopping cart. By the way, there is nothing illegal or pirated with the files in case you have any concerns.
