Join And Split Methods On Multidimensional Arrays ?

Aug 27, 2009

I 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".

Using Split / Join And Loop To Capitalize User Input

Oct 22, 2011

I need to capitalize user input from a text field by passing the data to an array and using the split() method, then then join() method and of course toUpperCase. I need to accomplish this with a loop. I only have a crappy ebook and haven't ever been in a java classroom.

Here's what I have which is not at all sufficient. I learn best from examples, so here I am...
<HTML><HEAD>
</HEAD><BODY>
<FORM ACTION="#" NAME=strn>
Enter lower case text
<INPUT TYPE=TEXT NAME="txt1" SIZE=20>
/

The following lines of code are just my attempts at guessing javascript logic/syntax
function arrays(){
for (var i=0; i<secondarray.length; ++i)}
firstarray=getElementByName.txt1
var secondarray =firstarray.split(separator[" ", 40]).toUpperCase();
/var secondarray.join([""])
<BR><BR>
<INPUT TYPE=BUTTON VALUE="Convert to Upper Case"
onclick="document.strn.txt2.value = document.strn.txt1.value.toUpperCase()"
<BR><BR>
<input type = "text" NAME=txt2 size=20/>
</FORM></BODY></HTML>
I know this much .array = string.split(separator[, limit]);.

Nested Or Multidimensional Arrays

Jul 23, 2005

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?

Associative Multidimensional Arrays

Jul 23, 2005

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:

Sorting Multidimensional Arrays

Apr 12, 2007

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?

Multidimensional Arrays In Loops ?

Jul 11, 2010

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.

Arrays/Methods Syntax

Apr 10, 2007

Programming assignment: Write a program for analyzing El Paso weather. This program must allow the user to enter dates followed by temperatures at these dates. Assume that we are only tracing one year, so the overall number of such dates does not exceed 366. Your must then output the following information:

*the average temperature;
*the list of all the days when the temperature was below freezing (i.e., below 32);
*the hottest temperature, and the list of all the days when the temperature was the hottest.
Main difference: In the previous assignment, following our advise, you stored the dates in one array (array of strings), and temperatures in another array (array of numbers).

For this new assignment, define a class Record whose objects contain two fields:

*a field date that contains the date, and
*a field temperature that contains the temperature.
Instead of using two arrays, use a single array of records (i.e., of objects of type Record).


The problem I'm having, is that I do not know how to read from two files and store the information into one array. (For example: with this assignemnt, I need to have one array with 366 fields, and in each field there needs to be a date and temperature.)

How To Use Join Method

Jun 11, 2011

What did that do, how do use this method.

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.

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.
