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)

Prototype To Sort An Associative Array On The Array Key (in Ascending Order)

Sep 1, 2010

I am building a customised javascript prototype to sort an associative array on the array key (in ascending order). Basically, I am separating the array keys into a separate array and then using .sort() to sort the keys and then reassembling the original associative array elements according to the sorted keys array.

The sorting works ok except that when I run the test code below, the outputed sorted associative array has an extra element at the end of the array whose key is the name of the prototype function and the value for that element is the function code itself. Obviously I am misunderstanding something about associative arrays or how javascript prototypes work.

Max Num Chars Allowed In Function Param?

Aug 2, 2010

I have a page working perfectly that passes up to 10-12k worth of data into a function via an 'onClick' event. That onClick is one of the <img..>'s attributes, directly. In case later that (dynamic) data gets larger, am I toying with potential problams because of some limit - either a limit in what can be passed into a JS function, or else a limit in the max num of characters allowed in an element's attribute(s)? What do you think is the reasonable amount that I can pass before things start to break? I may need to go up to 50k. 100k maybe, but I doubt that much.

Table Sorts Question

Jul 20, 2005

I have been trying to use a couple of javascripts to sort a table by
clicking on column headings.
Sorttable.js and tablesort.js which I found on the web...

I am encountering one problem.
In my table, the content of the first cell in each row contains a link
to another location.

When my table is sorted the displayed table appears correct(sorted)
but when I click on the link in the first column it goes to the link
which was there before the sort took place.

When I view source of the page, it always appears as my original html
page.

Obviously I am a javascript beginner(a stretch at that) so I am having
a hard time understanding what is happening.

It looks to me like the screen display is being changed/sorted, but
the actual html in my html file is not and the click is taking the
values from the source file..

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:
<html>
<title>Homework 5</title>
<body>
<script>
var num = new Array();
var x = 0;
var lastnum;
for (x = 0; x < 3; x++){
num[x] = window.prompt("Please enter a number between 100-999:");
if((num[x] < 100) || (num[x] > 999)){
lastnum = window.prompt("Enter your last number:");
for (x = 0; x < 1; x++){
num.sort();
window.alert(num);
} break;
}} window.alert("DONE");
</script>
</body>

Create An Array Sort Of Thing To Convert The Country Name's To Continent?

Dec 21, 2010

If you've seen from my previous posts in this forum, you may have noticed that i'm a newbie when it comes to javascript, anyway. I'm trying to create an array sort of thing to convert the country name's to continent, and set it as a cookie. I spent all that time writing a PHP script for this same thing only to find out that my webhost does not have the maxmind apache module. I also don't know how to get the value of the country from a javascript function.

PHP Code:
functioncountry_to_continent($country){$continent='';if($country=='AF')$continent='AS';--CUTOFFDUETOTEXTLIMIT,FINDTHEFULLCODEHERE:http://infinitymedia.pastebin.com/7WWDeyVTreturn$continent;}

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">
$(document).ready(function(){[code]...............

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?)

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:

var i=0;
for (i=1;i<=10;i++)
{
if (i == 1)

[Code]....

This outputs 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

How can I put this output into this variable: 'var ids' so I get out

var ids= [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];

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 ?
