convert the inputs to numbers instead of strings?I'm trying to make a calculator of sorts
var array = new Array();

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)
My question is ... How do I sort an Array on numeric, not character values ?
In the example below, after sorting the contents are 1,10,2,3 .
How do I get the contents to be 1,2,3,10 ? Code:
Is it possible to sort outer and inner strings at once? The sorted output should look like the following:
<category>Bars</category>
<name>Alpha Bar</name>
<name>Beta Bar</name>
<category>Cafes</category>
<name>Ara Cafe</name>
<name>Zeta Cafe</name>
Categories and names are both properties of one and the same array element.
I have the following compare function to sort the outer categories.
function compareCats(a, b) {
a = a.category;
b = b.category;
if(a == b) return 0;
else if(a b) return 1;
else return -1;
}
This is working fine. But I really would like to include the inner names in the compare
function without changing the structure of the array - if it could be possible. If not - what would be an efficient way to solve the problem?
I'm having difficulties arithmetically manipulating form element values.
I've entered data into the form, and I fetch them using a js, as:
p7Left = Number(document.form1.elements["p7_left"].value);
p7Right = Number(document.form1.elements["p7_right"].value);
...
...
scoreLeft = Number(document.form1.elements["left_score"].value);
scoreRight = Number(document.form1.elements["right_score"].value);
Then I add these as follows:
scoreLeft = Number(scoreLeft + p&Left + ...... +);
This does what I want; without the operator 'Number' I get a concatination
of the various variables (as expected). Is there some way of globally
defining all variables as numbers instead of strings?
What is the correct syntax for an nested array where each array element has 3 elements, a number and two text strings?
Code:
array = ['1, Old Man, Old Man','2 Black Sheep, Black Sheep',....]
should the text strings be in double quotes("")?
Code:
array = ['1, "Old Man", "Old Man"','2 "Black Sheep", "Black Sheep"',....]
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.

The follow jQuery code doesn't work. Does that mean jQuery doesn't support such a usage?
Code JavaScript:
var selectors = ['#header', '#content', '#footer'];
$(selectors.join(',')).addClass("new");
I was working on this problem that asks me to return an array of scores for each string (only for its content part, not URL) in the global variable, which is an array. For example, alert a score of 0 if the string z is not found, 1 if found once, and 2 for twice. My problem is that I can get the code to alert if it has found the word (ex. "the"), but I cannot manage to :
a) Assign separate scores for each string.
b) Make the search case insensitive i.e. "the" will appear in 0,1, but not in 2, where it is capitalized

var c = ["[www.facebook.com] Facebook is the best social networking site to coccent with your friends. ", "[www.google.co.uk] Google is the worldwide search engine. ", "[www.bbc.co.uk] The best news source for starting your day. "];
function findScore(z) {

in PHP I can create a multi-dimensional array with strings for keys,eg
$arr['key'] = array("item 1","item 2");
This works if the string is a variable as well, like
$key = "MyKey";
$arr[$key] = array("item 1","item 2");
I'm trying to something similar in javascript, but with no luck

I check the web and they only show you how to sort the whole array. I would like to be able to sort the subset of the 2D array.How would I sort the sub array independently. So only the a's together, then only the b's together, etc.

The 'array' variable contains strings representing the id's of different elements. If the for loop above were to finish iterating, would all the links in all three elements call the click function (that displays an alert message), or would only the last element ("element3") have the click function? For me, the latter seems to be the case unless if I'm doing something wrong, but I would like clarifications and, if possible, alternative solutions as to how I can achieve the former result.

I've an array of month/year to sort
Code:
var myArray = ['Oct/08', 'Jan/09', 'Mar/09', 'May/07', 'Apr/08', 'Dec/06'];
declare a hash of month with numbers as keys, split each array element and compare each month and sort it.
I have an array containing numbers. I want to order this numbers contained from major to minor in order to print them .. Here's what I have done:
var arr = new Array(6);
arr[0] = "10";
arr[1] = "5";
[Code]....
But I get no alert and a "myarray.sort is not a function" error.
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:

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;

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:
function country_to_continent( $country ){$continent = '';if( $country== 'AF' ) $continent ='AS'; --CUT OFF DUE TO TEXT LIMIT, FIND THE FULL CODE HERE: http://infinitymedia.pastebin.com/7WWDeyVT return $continent;}

I want to get the sum of all numbers in an text area irrespective of the spaces before between or after them. e.g. " 1 2 12 15 " =30
In the code below I can have multiple spaces or CR between numbers and it works giving me their sum But if i have a space before the first number or after the last number I get a NAN (

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]...............
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?)
I am working on a problem that wants me to use a for loop to give an array a random number for each of it's elements (total of 10) and then using a second loop to add them up and display the result.
<script type="text/javascript">
var sum;
var i=0;

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];
How can i output two maximum numbers of an array if they are equal?
var flower["roses", "violets", "buttercups", "daisies"];
var flowerAmounts[9, 8, 3, 9];
Output should be: The maximum amount of flowers is 9. There are 9 roses and 9 daisies.
