I'm trying to concatenate two arrays but it doesn't work.
The code looks like
Code:
And the console output looks like:
Code:
But I was expecting:
Code:
Does anybody know why those two arrays won't concatenate?
I have a string - comma separated - of array names. e.g.
var stringname = "array_one, array_two, array_three, array_four";
And I want to merge all the arrays named in the string into one big array.
(The string is produced via PHP as the exact arrays to merge may vary).
I've tried
var comboarray = comboarray.concat(eval(stringname));
But the eval()sn't working as I want!
I can't figure out why this doesn't work:
---------------------------------------------
greeting = new Array();
greeting[0][0] = "hey";
greeting[0][1] = "bye";
trace(greeting[0][0] + greeting[0][1]);
---------------------------------------------
Shouldn't this automatically create a multidimensional array? Can someone
help me?
Is there any way to associate name/value pairs during an array initialization? Like so:
sType = "funFilter"
filterTypeInfo = [];
filterTypeInfo[sType] = new Array("type" : sType);
I can do it using this:
sType = "String"
filterTypeInfo = [];
filterTypeInfo[sType] = [];
filterTypeInfo[sType]["type"] = sType;
but that seems rather cludgy. I want to use array objects not Object objects as described here:
I have a piece of JS code that uses the eBay REST API for searching. Each item returned is converted to an array and added to another array, giving the following format:
searchResults[1stItem]
searchResults[1stItem]["price"]
searchResults[1stItem]["bids"]
searchResults[1stItem]["endtime"]
searchResults[2ndItem]
searchResults[2ndItem]["price"] ... etc
What I want to do is sort the main array by an item in the second level of the array (ie price). Does anyone know how this can be done?
While arr[i] works fine in a loop, the addition of another dimension...arr[0][i]...means that it will not accept an assigned value.

View 2 Replies View RelatedI am working on a project which requires a method to join or split multidimensional arrays according to its arguments, which would be string delimiters for the various dimensions of the array.
An example of the join function might be:
The split function:
This would turn 'str' into an array like this:
I think I may have found the problem (but not the solution) - it looks as though javascript won't perform a method on an array which is part of another array. Firefox error console gives me "arr[0].join is not a function".
I need to be able to match a particular element in a "row" of a multidimensional array, and then find and reference the other elements in that "row".
Below is a sample of the whole array...

I'm fairly new to javascript. I have a code where I'm trying to generate scrollx1 through scrollx100. I can get the array to work with doc.write and I can get one concat variable to work in the element but when I combine them it doesn't work. Any suggestions as to what I need to add to this code:
var sp=1;
for (sp=1;sp<=100;sp++)
{
var sx = "scrollx";
var sy = "scrolly";

I would like to go to a url based on what the user selects from three seperate pull down menus.
Example user selects a product. Then selects a month and Selects a year.
month and year would join together Then create a path
<a href="product/month_year/DEFAULT.HTM">
I this possible with javascript.
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 have a HTML form containing multidimensional selects listing

JS HTML DOM reference I am not even sure it's possible. Code:

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?
