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'm using Tablesorter since few months and it was working very well.I did a small change yesterday in my php code: numbers over 1000 are nowformatted like this: 1 000, 1 000 000 instead of 1000 or 1000000.Since I did this change Tablesorter seems to have problems sorting this kindof formatted numbers with spaces. It just doesn't sort the way it should
View 1 Replies View RelatedI 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.

num.sort();
window.alert(num);

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)
I use the below file function to sort the html table

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.
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:
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.

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 ?

I have a string variable coming from a database, like 2,3,1,4,5,6,7.
The string is gotten from: <%=(Recordset2.Fields.Item("neworder").Value)%>.
And, have the following:
Is it possible to use the string variable to replace the index numbers so there will be a new position of the array?
I'm trying to generate random numbers 0-8 to use to access array indices.[code]Every once in a while, I'm getting a -1 in my console log. I read on a site that this line:[code]will generate a number between 0 and 10 (so 1-9).How is -1 being generated?

thta should of out put me "hello world" as it is what it is in array but it does not as there is 422 there That's my ID from database, and I gotta use itNow, if I change that ID to something in letters say to "i" then everything is fine. ex
PHP Code:
json_data_object.i.name
That one would work, but then I have to chnge JSON string thta pulls data from DB and i cant really do that...So the question is how can I make 422 (numbers) works the same way as just string values in the array/object tree?
I am passing data from a textarea to a div with javascript. The problem is the div is ignoring line breaks.
document.getElementById('layer1').innerHTML = document.getElementById('reply').value.replace("
", "<br /><br />");
e.g... i entered this in the textarea
test1
test5
test6
the result was in the div
test1
test5 test6
the div is completely ignoring the line breaks.?
I have been writing a script and need a gallery image to have it's width set on page load. My script works fine in safari, ff, chrome..but IE seems to ignore the line that sets the width of the image. It doesn't seem to be ignoring the other widths that are being set on certain divs. So it seems it is an image-only problem.
I thought it best to post a link to the page. To see the problem, you will have to have your browser set smaller than 885px in height. It's line 90 that seems to be ignored by IE
I have a system that provides titles that have had certain characters stripped out. Iwant to be able to select elements in an HTML document that match the titles, even when the titles in the HTML have notbeen stripped.For example, the title "F.B.I" will have the periods stripped to become "FBI", and I want to use that tomatch <div title="F.B.I">.
So far the only way I've been able to do it is to create a new attribute, set it to a stripped version of the title (using e.g. .replace(/./g, '') and match against that. It works, but it seems rather inefficient.Is there a simple and direct way to do this with jQuery?
I'm using the following chunk of code to find images located in a specific span and then I'm setting the span width to equal the width of the image that's inside of it. This is for adding captions to images through an editor that our writers use. By forcing the span to equal the same width of the image, the writers can just enter whatever captions they want and don't have to worry about manually adding <br /> tags to format the captions correctly.
$('.overview-content .caption img')
// once the image has loaded, execute this code
.load(function() {
// Loop through and find all images in the overview section
[Code].....
For some reason... IE and Opera completely ignore this function. Firefox, Safari and Chrome all add the appropriate inline style to the span.
I have to save the state of a form in a var before submitting it with the whole html, but if I alert the var, I get the original html without the updated input fields.

jQuery is ignoring the root element when passed through context. Am not sure if this is intended behavior.[URL]
