Generate An Array Of Integers?

May 26, 2010

I am implementing several scriptaculous sliders in my app... and one thing I can see being an issue is setting their "values" property to limit the selectable values.

This property takes an array of integers representing the allowable values. Unfortunately without this property, the slider will allow you to select a decimal value, so I can't just use a min and max if I only want integer values output.

Creating an array for a small data set is simple: for example "values: [0, 1, 2, 3, 4, 5]"

But some of my sliders will range into the hundreds and need an array of hundreds of allowable values. Is there a simple way to generate an array of 0 to 100 integer values (or more). I know I could use a for loop but it seems to me there might be an even easier way, though I cannot find it.

I would like it to fit in a code block like this:

javascript Code:

var s1 = new Control.Slider('handle1',
'track1',
{
axis:'horizontal',

[Code]....

EDIT: for further clarification, I found that PHP has a range() function that does exactly what I want. Anything comparable in Javascript? [URL]

JQuery :: How To Generate Workable Copy Of Array

Sep 7, 2011

I have an array of reference points on a canvas which should remain intact and reusable for repeated 'games'. I need a function to make a duplicate of myArray and call it pool, which I can have jQuery manipulate, such as remove indices from, without ever tampering with myArray.

Do I use:
var myArray = ['string1','string2',...]
$(myArray).map(function) {
return this = pool;
})

Or perhaps:
var myArray = ['string1','string2',...]
(function(makepool){function(.map(myArray) {
return this = pool;
});});

Then call:
var pool = ' '
$makepool()
And refer to the new element as $(pool)

Resolved Google Maps API V3 - Generate Markers From Array?

Aug 24, 2009

I pulled this code from Google's example section to make markers on a v3 Google Maps API (I have added my own lat/long points and corresponding event listeners, of course, but this is still the spirit of the code):

[Code]...

It's not throwing up any errors in Firefox's developer or in IE but there it sits, a blank map. I'm sure this isn't clean or optimized code, but it looks correct to me. I've color-coded the code above to show what "for" loops are being used to try to replace which code. Hopefully that makes this more sensible.

Calculating Sum And Average Of Integers And Display Value

May 25, 2009

I'm a newbie to javascript and I made this script
<script>
var num = parseInt(prompt("Enter the number of integers to follow"));
var sum = 0;
for (i = 0; i < num; i++){
sum += parseInt(prompt("Enter a number"));
}

if (isNaN(num)) {
alert("Invalid");
} else {
if (sum < 0) {
document.writeln("The sum is 0 and the average is 0");
} else {
document.writeln("The sum is " + sum + " and the average is " + sum/num);
}
}
</script>

The scenario : Create in javascript that will read a series of integers at the terminal. The first integer is special, as it indicates how many more integers will follow. Your javascript is to calculate the sum and average of the integers, excluding the first integer, and display these values to the screen. If the total is not greater than 0 then display "The sum is 0 and the average is 0". Did I write the script correctly? am I missing anything that a dumb person might do? for example the person might type in letters instead of numbers.

Simple Addition Using Integers Stored In Variables

Mar 31, 2007

i have this simple function...

function update(value, oldvalue)
{
var a = value;
var b = oldvalue;
var result = a + b;
document.form.fieldname.value=result;
}

and call the function using a field with this...

onkeyup="update(this.value, other)"

But all its doing is concatenating the 2 numbers together as though they are strings!!!

so if this.value = 11
and other = 15
it displays 1115

i want to add them and display the total, do i need to specify them as being integers or something?

Generate XML From XMLDocument

Jul 23, 2005

I have an XMLDocument that my web page downloads and manipulates as a
response to user input. I have lots of JavaScript that acts as a
controller between my view (html) and my model (xml). That works fine.

Once the user's done editing, I want to send the modified XMLDocument
back up to my server (as XML). The problem is, I can't find a way to
use JavaScript to generate XML from an XMLDocument. Is there some
obvious API that I'm missing? I assume there's more than one way to do
it (one way for IE and one way for Mozilla, who knows how many others),
anybody want to share?

Generate Unique ID

Jul 23, 2005

I have a page with 641 images in it. Each image can be clicked with as
result that the image source will be changed. For this the images need
to have a unique ID. But to do this manually for 641 is just too much.
Is there a way to give each image his own unique id without setting
them myself?

The image:

<img src="images/hokje.gif" id=""

How To Generate Link To PDF From Current Url

Jul 20, 2010

I've looked on the forums and google for this, and I can't find anything exactly right:I have a universal navigation, one link is "Print PDF" - I don't want to hand code each page individually.How can I use the current page url - such as "website.com/accomodations.php" to print a PDF named after the page, like "accomodations.pdf", or even better "pdfs/accomodations.php"?OR just any way to print a PDF associated with the current page - I guess it doesn't necessarily need to be the URL that links the files.
