Variable Multidimensional Array Names With Window?

May 5, 2009

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:

Code:
// here's my multidimensional array
myArray = new Array();
myArray['id'] = 'foo';
myArray['sub'] = new Array();
myArray['sub']['id'] = 'bar';

[Code]...

Variable Multidimensional Array Names With Window[]?

May 6, 2009

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?

Access A Part Of Multidimensional Array Based On A Variable That Is Passed Into The Function

Sep 12, 2002

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.

Using A Multidimensional Array?

Jun 5, 2009

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.

Look Up Value In Multidimensional Array?

Apr 22, 2010

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.

Multidimensional Array Length?

Jul 8, 2010

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.

Create A Multidimensional Array?

Sep 30, 2010

I'm trying to create a multidimensional array (and it's my first time using one) as an easy-to-modify way of populating content into a cycling banner script. However I seem to be having issues with actually accessing the content in the array.So currently my array looks like so:

Code:

<script type="text/javascript">
var banner = new Array();
//Option 1

[code]...

But when I do a "document.write(banner[0]['title']);" in my body, it doesn't seem to want to oblige.

JQuery :: Processing Multidimensional Array With .getJSON

Dec 24, 2010

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.

JQuery :: How To Refer Nested Field In Multidimensional Array

Sep 8, 2011

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?

Multidimensional Array To PHP Array?

Feb 17, 2010

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

<br />
/*<br />[<br />
[userID (int), name, username, email, password, other 1, other 2, other 3, other 4, other 5, other 6, admin(int)],<br />

[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.

Display Names Listed In Array?

Nov 28, 2009

i was wondering how you would go about displaying an array of names without hard coding them in the .htm file? example: i have a array of names and the way i list them is to hard code each table entry. what i want to do is have the same array of names, but use javascript to display the names without hard coding it. i want to list 9 columns and have it go until the last name is listed.

i have: function initalize()
{
this.length = initalize.arguments.length;
for ( var i = 0; i < this.length; i++ ) this[ i + 1 ] = initalize.arguments[ i ];
}
var familynames = new initalize('list of names here');

Javascript Get Vvariable Names From Array And Then Use

Oct 23, 2007

Say I have some variables setup like so;

<script type='text/javascript'>
<!--
panelsArray = new Array("form0","form3","form4","form5","blotter");
var blotter = new Array(&#3936;',&#39462;',&#39762;',&#39292;','block','');
var form0 = new Array(&#39202;',&#3955;',&#39609;',&#39185;','block','');
var form3 = new Array(&#39948;',&#3968;',&#39301;',&#39139;','block','');
var form4 = new Array(&#39861;',&#39655;',&#39400;',&#39158;','block','');
var form5 = new Array(&#390;',&#390;',&#39805;',&#39291;','block','');
// -->
</script>

and I want to parse the first array and then within that loop I want to get the variable name from the 'outer' array and then reference the contents of the array with that name... I was trying to do the following but it doesn't work, I'm obviously missing something about transmogrifying the text "form0" into a variable name...

for(f=0;f<panelsArray.length;f++) {

thisPanel = panelsArray[f];
alert(thisPanel);
thisPanelWidth = thisPanel[0]
alert(thisPanelWidth);

}
