## JavaScript Date Difference, Accounting For Leap Years

Jun 19, 2006

I'm really sorry to post this as I know it must have been asked
countless times before, but I can't find an answer anywhere.

Does anyone have a snippet of JavaScript code I could borrow which
calculated the difference in years and days between two dates, and
takes leap years into account?

I'm calculating the difference in the usual way, i.e....

var difference = dateTo.getTime() - dateFrom.getTime();

....and converting this millisecond value into days by using...

var daysDifference = (difference/1000/60/60/24);

But how do I then display the difference in days AND years? I've tried
the following:

var yearsDifference = Math.floor(daysDifference/365.25);
var daysLeft = Math.floor(daysDifference-(yearsDifference*365.25));

....but it gives me inaccuracies. For example, if I use my code to
calculate the difference between 05/01/1998 and 05/01/2000 it returns 1
year and 364 days!

## Population Clock - User To Be Able To Choose Future Years Up To 2020

Dec 9, 2010

I want to code a world population clock similar to the one here [URL] but simpler: I want the user to be able to choose future years up to 2020 (just years, not months/days), and have the population grow by 1 percent each year. So far I have a code for the world population, but I have no clue where to begin in terms of making a list of the years with the option to increase the population.

## IndexOf - Leap Year In Date Picker

Jan 7, 2012

If you see my last post, it was a piece of this code that I was learning for/loops but now I have that all working(hence the new topic) and I'm having a problem with indexOf. Here's the whole script(its a fun little date picker)

function popSel(v){
var days;
var x;
if(v==01 || v==03 || v==05 || v==07 || v==08 || v==10 || v==12){
x = 31;
}else if(v==04 || v==06 || v==09 || v==12){
x = 30;
}else if(v==02){
/*var yr=document.getElementById("year").value / 4;*/
var yr = 2003 / 4;
if(yr.indexOf(".") == -1){ /*If you divide a year by 4 and the value is a whole number, it's a leap year*/
x=28;
}else{
x=29;
}}for(i = 1; i <= x; i++){
days += "<option value=" + i + ">" + i + "</option>";
}document.getElementById("day").innerHTML=days;
}
The whole script works but feb doesn't change?

## Form Field To Check For A Leap Year?

May 3, 2010

A non leap year can be divided by 100. But a leap year is divisible by both 4 and 400.This seems so simple yet I can't nail it. I'm taking an accelerated Javascript class and I was able to do all the problems up to this one. It's confusing me, or it may be that I've been up since 2 working on homework and getting ready for another test.

Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

## Calendar - Dropdowns Containing Months And Years

Apr 7, 2009

I'm trying to get a pair of drop down menus to appear on the screen, one containing months, and one containing years. I know the one containing years works, since it hasn't been changed at all since it was working, but the month box used to be a textbox. I tried to convert it over to drop down box using the same code as the year box, but it hasn't seemed to work.

<script language="Javascript">
var m1 = January;
var m2 = February;
var m3 = March;
var m4 = April;
var m5 = May;
var m6 = June;
var m7 = July;
var m8 = August;
var m9 = September;
var m10 = October;
var m11 = November;
var m12 = December; .....

document.write('<select name="selYear">');
for (var x=0; x <= 10; x++ ) {
if(x != 5){
document.write('<option value="' + x + '">' + yearArray[x] + '</option>');
}else{
document.write('<option value="' + x + '" selected>' + yearArray[x] + '</option>');
}} document.write('</select>');
</SCRIPT>

## What JS Framework To Choose To Learn JS

I'm experienced with PHP and I'm familiar with JS syntax but still a beginner.

Now I want to learn AJAX And JS and I've looked at jQuery but it doesn't look like JS to me, I mean I'm sure it is but it looks to me like jQuery has a syntax of it's own and I want to learn not just a framework but also the underlying language.

So now my question is; what framework will be the best choice when that is my goal?

## Dropdown List - Choose One Option - Okc - Pc Or Cc

Oct 2, 2010

This is dropdown list...if user choose okc in first list(vrsta) in second (celik) user can choose C0270 and C0370...if chosen pc in first list in second user can choose C1330 and C1530 etc... There are two boxes...ans15 and ans14...and button which user clicks

The idea is that user choose one option(okc,pc or cc) and choose option (C0270 or something else) onclick some values should be written in boxes

Example: chosen okc and C0270 in ans15 "hello" and in ans14 "goodbye" should be writen if chosen okc and C0370 in ans15 "hi" and in ans14 "bye" should be writen:

## Force User To Choose Radio Options Before Submit?

May 27, 2009

I'm trying to write a shopping basket in ASP and I need to force the user to choose one or more "Option" radio button(s) before allowing the form to submit.

For example:

<input type="radio" name="option1" value="1">Red
<input type="radio" name="option1" value="2">Blue
<input type="radio" name="option1" value="3">Green
<input type="radio" name="option2" value="1">Small
<input type="radio" name="option2" value="2">Medium
<input type="radio" name="option2" value="3">Large

I want the user to HAVE to choose a colour and size from the above options before the form will submit or else they will get a Javascript popup message asking them to make a choice. (There may also be more/less options so it needs to be dynamic)

I know ASP inside out but very little knowledge of Javascript so once i have the basics of how to do it I can make the code dynamic. There will be a maximum of 5 "Options" for a product and a maximum of 6 choices for each Option.

## Firefox Autofill Plugin - Choose Random Values For Forms

May 6, 2010

I'm using the autofill forms plugin for firefox which can be found here: [URL]. I use it to automatically fill various web forms. But I would like certain values to be chosen randomly from a list I create. I contacted the developer and he said the add on probably does not need a new feature because there is a 'dynamic tags' function to fill certain forms with dynamic values (e.g. the current time or date). He has given over the project to another developer and told me I probably would find a solution in a good javascript programming forum.

Basically, I just need a javascript code which chooses on item from an array randomly, I guess? Here are sample dynamic tags from the plugin:
<datetime> new Date().toLocaleString()
<useragent> navigator.userAgent
<langcode> navigator.language
<resolution> screen.width+'x'+screen.height
<clipboard> this.getClipboardText()
