Generate An Array Of Integers?
May 26, 2010I 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]

Confirm/Searching/Counting An Array?
Oct 28, 2009I feel stupid for asking a question about searching arrays, when there's a very similar thread that has been answered just recently on the first page; however, I'm still having trouble contemplating my own scenario.Basically, my program prompts the user for the length of the array and then asks the user to fill the array with words.I want to confirm if the user wants to search the array for those words. If so, the user will then be prompted to enter the word he wishes to search for; if found, the location of that word will be reported and the number of times the word has been searched for will be kept track of in a separate array.Here is what I have so far:
/* -- phase 3 ------------------------------------------------------
search for words the user asks for
*/

JQuery :: Playing Arround With Integers?

1.000.000,00 // throw error

And on success I have to get all numbers before the dot or comma .
Calculating Sum And Average Of Integers And Display Value
May 25, 2009I'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.

Mar 31, 2007i 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?

Oct 7, 2005This involves the use of an order form used to process a purchase via Paypal. The items are small rhinestone letters for names and such.
The form is very simple in that the purchaser enters into form field one: the letters they wish to purchase.
Form field two (this is where I rely on common sense by the purchaser): enter the number of letters entered in form field one.
Based on the number of letters entered in form field two, my form processes the correct cost for the purchase.
As you have already figured out, I am beginning to see people enter their letter orders w/out entering the number of letters ordered.
All that said: a way to count the letters entered in form field one and auto-populate form field two with that number. Code:
