## Function For Duplicate Numbers And Output

What's supposed to happen is when the program is run the user clicks on "Select your Numbers!" their then asked for 5 numbers which they input and then the numbers are checked by a function called �isAlreadySelected� for duplicates and if there is an alert is shown.

## Array Undefined After Setting Equal To Values Of Several <INPUT> Fields

Apr 7, 2009

I keep getting <undefined> when I alert out the value of my array 'fadeimages1'. Using php/mysql I retrieve filenames from a directory and create <INPUT> fields to store the filenames. In the javascript portion of the code, I use getElementsByName() to retrieve all of the <INPUT> fields. I then declare an array, 'fadeimages1'. Next, using a for loop I try to copy the values from the <INPUT> fields into the array 'fadeimages1'. When I alert out the length and value variable for each <INPUT> field, I get the correct filename, but after trying to store the value into 'fadeimages1' array, I get value is <undefined> when I alert it out. BTW, the following code uses 'fadeimages1.push()', but I also tried 'fadeimages1[i]=...'. Both result in <undefined> values.

## How To Print Out Numbers Array

Dec 10, 2010

I have an assignment that just asks you to input some numbers and then if the number isn't between 100-999 just to enter the final number and whatever the final number is to print out everything that is less then that number. For example: I enter 120, 128, and 1. It will then prompt me to enter the final number which I put 124. Now I have it set as 124 so everything less than 124 it will print. So I want the array to print 124, 120 and 1.

Code so far:

<title>Homework 5</title>
<body>

var num = new Array();
var x = 0;
var lastnum;
for (x = 0; x < 3; x++){

if((num[x] < 100) || (num[x] > 999)){
lastnum = window.prompt("Enter your last number:");
for (x = 0; x < 1; x++){
num.sort();
} break;
</script>

## Sort Array Of Numbers And Letters

Jul 6, 2010

I have an array which is populated by a count of instances from another array, so its ends up with data like:

I need to sort this by the number before the 'x'.

At present, a .sort() would put 1 - 9 before anything greater than 10, obviously not what I'm after.

How can I make it put this array into the correct order (e.g 22 x something else, 17 x another event, 5 x that event, 2 x this event)

## Array :: How Would I Make The Buttons For The Numbers?

Jul 30, 2011

I am starting to learn javascript and have been trying to make a image gallery. I was hoping to take an array of src and create a link for each one which when clicked on changes the src of an already existing img.My question though is how would I make the buttons for the numbers.I feel like a loop would work for this but I just can't seem to figure it out. I don't know how far off I am in thinking that through a loop I could create functions with a name plus the i variable.And in each function there could be something like:

Code:
document.images["destination"].src = images[i]
That would then produce an <a> with the href equal to the function name + "i" with the title being "i" as well.

Am I way off? How would I execute that? A little explanation about my code. I am going to be using a loop to add the images that will vary in amount for each page that is why I have the push function just for this test. And the document.ready is because I've been using some jQuery.

Code:
<script type="text/javascript">

## Multiple Array And Random Numbers ?

Nov 10, 2010

I have a quick question with multiple array and random numbers. If i generate my random numbers in one array, how would i take a selection of those numbers and put them in another array?

Ex: array 1: 25, 34, 38, 40, 22, 49

Want to move numbers between 30 and 50 to another array.

array 2: 34, 38, 40, 49

Is it as simple as for loops and if statements setting the conditions? do i use a sorting method? (selection? bubble?)

## Unable To Output Text Of Array To A Specific Div / Enable This?

I've managed to output the text of my two arrays to a specific div (in this case the div's id is ''number') - BUT I'm only seeing the last data from each array (it's a train number and a train name) so instead of getting the entire list from 800 to 870 and the associated names I'm just getting the last pairing which in his case is 870 Zulu.

## Create An Array Of Numbers Counting From 1 To A Given Number?

Mar 20, 2009

I just want to create an array of numbers counting from 1 to a given number.

At the moment I have the for loop running like this:

## Create A 4 X 4 Array Filled With Numbers Input By The User?

Jul 15, 2010

I'm trying to create a 4 x 4 array filled with numbers input by the user. I then need to rotate the grid clockwise like I've shown below.

01 02 03 04
05 06 07 08
09 10 11 12
13 14 15 16

13 09 05 01
14 10 06 02
15 11 07 03
16 12 08 04

I made all numbers double digit just for show in the example so the table is easier to read. So far the code I have is just trying to create the array and fill with numbers from the user. This asks for a number once then doesn't display anything at all.

## Iterate Array And Grab X Numbers Based On Pointer?

Jul 1, 2009

I'm trying to figure out how to do this via Javascript.

Lets say I have an array like so:

var myArray = [11, 33, 44, 23, 32, 43];
var finalArray = new Array();

And I have the following variables

var lastNumber = 33;
var getNext = 2;

I want to use the lastNumber for a starting point in the array and then based on getNext, grab the next x numbers that getNext specifies and shove into finalArray.

That case moves forward in the array.

Second case would be the opposite, get the previous x numbers based on getPrevious in the array. So I'd start at lastNumber and then grab x numbers before it based on getPrevious.

var lastNumber = 33;
var getPrevious = 2;

I'm not sure if you can traverse backwards in JavaScript. But more importantly I'm not sure how to point to lets say 33. How can I do myArray[1] essentially based on I'm pointing to 33 and then how can I grab the next x in myArray ?
