I have an array "arr" that is an array of objects. Each object has the same 7 properties.I want to find the index of the object with a property that matches a certain value x in the array arr. How can i accomplish this?The array has hash tables associated with it.arr [ obj [ i ] . property1 + "_" + obj [ i ] . property2 ] = arr [ i ] ;so whats the index of the object where .property1 = x ?

I have the below array called "results". When I loop through all document elements I would like to check "field_name" against the "results" array and see if it exists and what index number it is at??
// Split the comma delimited response into an array
results = result.split("~");
//Loop through array and populate fields[code].....
I am trying to get the index of a li with a specific class. I know I'm selecting the right object because I can apply a CSS class to it (eg change border colour) but when I try to get the index it returns -1. But I know the object exists as I can alter it. :-s
jQuery(document).ready(function() {
var active = $("#tertiarynavigation .bordered").get(0);
var num = $("#tertiarynavigation li").index(active);
alert("Index: " + num);

I am wondering if my code *should* work. I have a php file that reads in images from various folders. It stores the file paths in a javascript array by using echo statements. The array is also defined in the php file, as below, outside of the php tags.
var galleryarray = new Array();
for(var i=0; i < galleryarray.length; i++)
{
[code]....
I am getting an error when running the HTML file that says "galleryarray[f1][f2] is undefined". I have another version of this that stores the file paths in a single-dimension array, and this works fine. I am thinking that there could be something wrong with how I am using the multidimensional array in the javascript.
I want a lookup table that matches url fragments to the name I want to show. For instance, if a url contains "yahoo.com", I want to print "Yahoo." For now, I created a multidimensional array that maps url fragments to a name. such as,
var urlMapping = [
{ urlpath: "yahoo.com", mapto: "Yahoo"},
{ urlpath: "google.com", mapto: "Google"}
];
So, say I have a variable urlVar, where the value is some URL (for example,[URL]).Is there any way - other than looping through the array for every variable - to check if urlVar contains any of the substrings in urlMapping.urlPath, and if so, output urlMapping.mapto? (In this case, I want urlVar to find that it contains the substring "yahoo.com" and output "Yahoo".) In my code, I anticipate that I have 100 variables checked against 50 mappings, and performance is important to me.
Is there any function or property for finding out the size of the first (or for that matter any) dimension of a multidimensional array?EDIT:There seems to be no such functionality, I found a solution that does not require it. If anyone is reading this for the same reason; it needs to be scripted.

Whats wrong with this code? i decalre resultArray as a new Array(). Then in a for loop for each resultCount i declare resultArray[resultCount] = new Array().
Then i try putting in values for every resultArray[x][y], but when i go to output the array in another function, everything in resultArray is undefined.code...
I have the following (valid) json string:[code]Using firebug, I can see that the GET is returning the entire json string. However, alert only results in one of the two "text" strings being displayed ("and again"). Analyzing the watch/stack window shows that the "json" object resulting from the getJSON call has been reduced to a single "chat" element, instead of both "chat" elements present in the array.

I'm trying to use variable variable names using the window[] functionality. It works fine when you literally specify an array's base variable name, but I have a multidimensional array and would like to use window[] to build the name of the specific sub-array I'm looking for, like so:
// here's my multidimensional array
myArray = new Array();
myArray['id'] = 'foo';
myArray['sub'] = new Array();
[Code]....
However if temp is the name of a sub-array (e.g. 'myArray[sub]), and not the base array name(i.e. 'myArray'), then window[temp] evaluates to "undefined".
Can the window[] functionality handle this somehow, or do I have to resort to eval() or something else?

I want to convert multidimensional array to JSON string.

I want to convert this array to JSON string and to get the JSON string back as an Array.
I'm using getJSON to retrieve information from a header record and the corresponding detail records and display the detail records in a table. The PHP script that is called returns a JSON string (via json_encode) that looks like this:
{
"srn":"1",
"invNo":"1",
"custNo":"39750",
"purchOrd":"PO12345",
"shipVia":"our truck",
"jobNo":"E001-11",
"invDate":"8/3/2011",
"taxCode":"1000000",
"shpName":"testName", .....
Here is the html table:
<table><thead><tr>
<th colspan="2" >Item Description</th>
<th>Quantity</th>
<th>U/M</th>
<th>Item Price</th>
<th>Item Amount</th>
</tr></thead><tbody>
<tr class="p_row_1"> .....
And here is the $.getJSON:
$.getJSON("GET_INV_INFO.php",{srn:'<?php echo $srn; ?>'},function(s){
// Get Header Info
$('#ip_invNo').html(s.jobNo);
$('#ip_invDate').html(s.invDate);
$('#ip_custNo').html(s.custNo);
$('#ip_purchOrd').html(s.purchOrd);
$('#ip_custName').html(s.custName); .....
My problem comes in the getJSON section where I'm trying to populate the table with a record. I don't know how to refer to the different fields in array 's'. I've tried the following and many variations, but to no avail:
$('.p_row_'+i+':nth-child(1)').html(s.row.i.itemNo);
$('.p_row_'+i+':nth-child(1)').html(s.row[i].itemNo);
How do I refer to a nested field in a multidimensional array like this?
I have an array of integersI like to retrieve the max number and index of max number from that array without using Math.Max() function..Presently in this below code, I have 4 dynamic values, end user will be select degree from combo box, entering the values semester, Max marks and Obtained marks as numeric values. Once entered dynamic rows will be created and it also calculate the percentage by the formula (om/mm)*100 for each row on clicking Sum and it also creates new columnŠI needed to have code when the degree changes only.. it should calculate the sum of all max.marks and Obtained marks of each semester and then calculate percentage by above formulaŠ and also new column should not be createdsort with max markswhat is the easiest way...

I want to create an associative array dynamically pulling the index values from an array (propertyArray); Associative array is created inside create function and then returned. But after it is returned, I cant use index names to retrieve values. It returns undefined as below code shows.

function create(){
var array=[];

how would i build a multidimensional array? would it be: PHP Code:
var rinksAndPriceArray = new Array();
rinksAndPriceArray[0] = new Array();
rinksAndPriceArray[1] = new Array();
i've figured that out so far.
now, i want to be able to access a part of one of the arrays based on a variable that is passed into the function
the variable i'll send in will be the first part of the array ex: rinksAndPriceArray[0][0] and i'll want to return the rinksAndPriceArray[0][1] value.
I am dynamically adding text boxes within a table and I want to be able to dynamically remove them as well. I have this part of the code figured out.
With each text box that I add, I also add a link in the same row, but different cell that will be a "remove" link. Im having trouble finding the index of that row by clicking on a link.
I can find the index by clicking on the row(tr) but I can't seem to figure out how to find the index by clicking on the link inside of the row.
Here is my code:
Creates the link dynamically in the 4th cell:
Code:
Remove Row Code:
Code:
Find Row Index Code:
Code:
I beleive the problem is in the rows[i].onlick part, since I'm not techinically clicking on a row, Im clicking on the link. I have tried changing the rows variable to:

But that doesn't work.
HTML Code:I have been trying to figure this out for awhile. I have a multidimensional array in JavaScript that is 12 columns wide and an unknown number of rows like so

[code]....
All the values are string except the (int) ones. This is for a real time user editing page for my site. I have the JavaScript array made now I need it so when the "Submit" button is pressed it turns the array formated like that into an PHP array and saves it as a variable.
This is my table structure, I want to find out the index of the tr which first td is empty, in this case, the index should be 1, how to pick it out?

<td>1</td>
<td>1</td>
<td></td></tr>
<tr><td></td>
<td>1</td>
