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.

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 am creating a form in which a checkbox is checked based on specific info from previous page.The info I am passing is the client ID (which is a number I can pass in the URL variable)In the form I have a list of clients (with checkboxes next to them)Now if you come from a specific client page the checkbox with the client name should be already checked since you are getting info regarding that client, with the option of selecting other clients..So how I get a specific checkbox checked based on a specific variable?

The code below is the relevant part to an autosuggest feature. The variable that isn't being passed is "firstValidIndex". It is being set appropriately, but when it is used in "sortArray()", its value is 0.
// here we must check to see if where the string matched was at the beginning of a string inside this.aNames
// firstValidIndex is the first index where the char is at the beginning of a string

This is the first question I couldn't find answered by Google! No doubt the answer is out there, but...
So I have a function that is being passed an array of nodes: some of them plain vanilla DOM nodes, (say, those created by document.createElement), others are jQuery nodes (say $("<div></div>").
What's the best way to determine if a node is of each type? I can obviously look at the node contents, but I wondered if there was a "best practices" here?

I am writing a Javascript to sort and write out some stuff. PHP is not an option so I need to get this script working.
The problem arises when I want to make a link to the next page. (i.e. Like the link in google for the next 10 results)
I have <a href=# onclick=FUNCTION(VALUES)> written dynamically by the script.
It is written onto the document correctly, but the problem is, when the link is clicked, some seemingly random values are passed to the function.
I also have an invalid character error that arises when I pass the "whereVARquoted" variable into my function (code 2) which disappears when the variable is removed (code 1).
My code is below:
Code 1:
<script>
Code 2:
<script>

In one of my functions I got the following lambda function. It works as intended, but I got a tiny problem. I'm trying to access the function-scooped variable "matched" and set it's value to "true". The problem is that it seems like the variable is existing as a local variable inside the lambda function, even if it's not declared inside the lambda function itself. So, the change "matched = true;" does not effect the variable that I declared.
Code:
//... code
var matched = new Boolean(false);
xmlhttp.onreadystatechange=function() {
if(xmlhttp.readyState == 4 && xmlhttp.status == 200) {

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.

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.

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.
