I am using the following Javascript to print the year, but I would like it to just have "03" instead of "2003". Can somebody tell me how to do this? I've tried searching several different sites and I can't figure out how to do this.
document.write(now.getFullYear());
I've wrote a very similar function that works perfect but no matter what i do here, the result is always the same. I can't seem to enter a 2 digit number in the second box for weight and therfore won't work. It seems to work fine for up to 9 lbs though.

Here is what I'm trying to do. I have a 12-digit
(UPC-A) javascript validation script which works great. All I need now
is a similar script for 8-digit (UPC-E) type script? I don't want to
convert it to a 12-digit UPC-A before validating it as a 12-digit
number. I would prefer to just be able to calc the number, as an
8-digit number, check digit and all, just like I am currently doing
successfully with this 12-digit validation script: Code:
I am creating a JS function that takes a time input in minutes only and divides that number by an inputted digit. I would like to know how we use Javascript to convert that result into minutes and seconds.For instance, 30 (1800 seconds) divided by 4 = 450 seconds. How do I show that as 7:30? I can divide by 60 to get 7.5, but I don't know how to go from there. I got as far as the following, then got stuck.

a.) specify two parameters for the changeYear function: today and holiday.
function changeYear(today)(holiday){
b.) in the first line of the above function, use the getFullYear() date method to extract the 4-digit value from the today variable and store the value in a variable named year.
first line
c.) in the second line; use the setFullYear() date method to set the full year of the holiday date object to the value of the year variable.
second line
d.) in the third line, use a conditional operator on the year variable. The test condition is whether the value of the holiday date object is less than the today date object. If it is, this means that the event has already passed in the current year and the value of the year variable should be increased by 1.
third line
e.) in the fourth line of the function, again set the full year value of the holiday date object to the value of the year variable.
First script, 'xxx.js' returns value 'document.write('integer');
So in HTML:

will write ie. 123 on my page in browser.
Can I get this integer or text 'document.write('integer')' to variable in
another script? So it would be something like this:
<script landuage='javascript>
a=<script ... src='xxx.js'></script>;
a*=20;
document.write(a);

What is the best way to validate a field as a positive or negative
integer?
function calculateGst(exGst) {
//percentage of current gst.
var gst = 10;
var gstAmount = (exGst * (1 / gst));
var gstInc = (exGst + gstAmount)
alert(gstAmount);
alert(gstInc);
}
now, the exGst parameter comes from an document.getElemenetById('txtExGst').value in an onclick event.
the problem is this. if 400 is entered at exGst, the gstAmount spits out 40, as it should, but the gstInc spits out 40040...so its treating it like a string rather than a number...

I'm little struggling with the following. How can you create the following integers?

Is there a native JS function to accomplish this?

checknew sends the number 1 or 0 depending on what load sends, and in turn, its just alternating 1/0 every second.
I am unsure how to send the number I get in load(cv) to checknew(cv) every 1 second on setInterval.
I have some one page whose div elements are aligned by JavaScript. The JavaScript just check a set of div elements to find the max offsetWidth, then set all div elements' width to be the max offsetWidth. It works perfect in most browsers and locales, but it fails on french-France in Firefox on Mac. In this case, the content of div wraps.
<div id="divFoo">
Heure de début :
</div>
for above HTML, below code report "79".
javascript:alert(document.getElementById('divFoo').offsetWidth);
but below code report "79.1333px".
javascript:alert(window.getComputedStyle(document.getElementById('divFoo'),null).width))
The gap between 79.1333 and 79 makes incorrect width set to inline style.I used to thought that offsetWidth and width should always be integer. Is there any way to make offsetWidth round correctly?
I want javascript function that could convert from integer to float e.g if user enters 10 then it should convert it to 10.00 or better 10.000. If user enters 10.0123 then it should convert it to 10.0123.
