Working With Dates In Form
Sep 15, 2010
So I'm supposed to be using a form to get the date of Easter or Ash Wednesday and return the other. It should also check that the date for Easter is a Sunday and the date for Ash Wednesday is indeed on Wednesday. What I have so far isn't working. I'm not sure what I'm doing wrong. I know my if...else logic isn't going to work right since I've assigned new Date () to easter and ash. How to clean this up and get it working right?
<html>
<head>
<title>Ash Wednesday to Easter Sunday</title>
<script type="text/javascript">
<!--
var ash = new Date();
var easter = new Date();
var temp;
var month = new Array ("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December");
function convMonth (){
}function fnAshToEaster (){
ash.setDate(document.formAshToEaster.ashDate.value);
ash.setMonth(document.formAshToEaster.ashMonth.value);
ash.setYear(document.formAshToEaster.ashYear.value);
easter.setDate(document.formAshToEaster.easterDate.value);
easter.setMonth(document.formAshToEaster.easterMonth.value);
easter.setYear(document.formAshToEaster.easterYear.value);
if (ash == "") .....

I am having trouble working out the difference between two dates.
[Code]...
This gives a value of 2,678,400,000 but the amount of milliseconds in a day is actually 86,400,000

There is a form that I have been working on. The form needs to display information on it that, ideally, would be automatically generated.
So, for example, I open this form today 9/6/2007 and I sent it out. The form result would show the current date with a time of 6:00am and then the previous day's date with a time of 6:00am.
----Form Data----------------------------------
Data for: 9/5/2007 6:00am thru 9/6/2007 6:00am
Name: Yourname
Number: 123abc
-----------------------------------------------
So, again, I'm trying to write a script that will present current day and the previous day on the form and the results. I hope that I have been clear enough.
If anyone has any suggestions I am certainly open to look at them.

I downloaded a calendar script that allows a user to just click on the date and have it populate the form input field- the problem is it lets you enter dates previous to today. I would like it so it could not enter any dates less than today.
Problem is, I know nothing about javascript. I am less than a noobie.
Would some kind soul have a look and see if it would be possible to do and show me what to do.
The code is below. There is also a css file which I did not include.
Code:
function positionInfo(object) {
var p_elm = object;
this.getElementLeft = getElementLeft;
function getElementLeft() {
[Code].....

This problem seems to occur dependant on the computer system settings.
I have no issues when the system date is set as M/d/yyyy but I do
have a problem with the system date set as d/M/yyyy.
I have a text box on a web page that holds the date ie)
document.frmTimesheet.tWeekFrom.value = 19/12/2004
theDate = new Date(document.frmTimesheet.tWeekFrom.value);
// split into day, month, year
iDay = theDate.getDate();
iMonth = theDate.getMonth()+1;
iYear = theDate.getFullYear();
alert(iDay);
alert(iMonth);
alert(iYear);
iday= 12
iMonth= 07
iYear= 2005

I am currently using a function to validate a form on the client side
(see code below). At the end of the function, I would like it to also
compare a startDate against an endDate to ensure that the endDate is
greater than (comes after) the startDate. The date format I'm using is
MM/DD/YYYY and it's writing to an MS SQL Server 2000 database table
via ASP. Code:

I want to obtain the user's current age by comparing their date of birth
(user inputs) to the current date.
I know how to get the Current Date but I'm not finding how to calculate the
Current Date minus the User's Birthday.
It would be something like yourage = curdate - bday;
I will then use the results to determine if the User is Over 21 or Under 21.
I'm going nuts trying to figure this out.
Is there an Easier Book to learn this stuff other than the "Begining
JavaScript 2nd Edition". Code:

If I had a date in the format "01-Jan-05" it does not sort properly with my sort routine:
function compareDate(a,b)
{
var date_a = new Date(a);
var date_b = new Date(b);
if (date_a < date_b)
{ return -1; }
else
{
if (date_a > date_b)
{ return 1; }
else
{ return 0; }
}
}
I guess it expects the date in mm/dd/yyyy format.
Do I have to change:
var date_a = new Date(a);
var date_b = new Date(b);
so it recognizes a correct format?

I have a successful script for determining today's date. Does anyone have anything for determining tomorrow and the next day since it would have to look at the day of month and month of year?

A HTML Form has 2 sets of 3 dropdown select lists. The 1st set is for users to enter the start time & the 2nd set is for users to enter the end time. The 1st dropdown select list in both the sets is where users will select hours, the 2nd dropdown select list in both the sets is where users will select minutes (the 2nd dropdown select list in both the sets have 4 options - 00, 15, 30 & 45). The 3rd dropdown select list in both the sets is where users will select either AM or PM.
Now it's quite obvious that the start time can come after the end time (on the same date). For e.g. you can't let users select the start time as 9:00 AM & the end time as 6:00 AM.
How do I validate that the end time always comes after the start time & vice-versa?

I would like to know how to achieve this. I want to know the difference between two dates in months, how much days left over, and how much hours left over. I do not need days or hours equivalent to the months remaining. The problem is I also want it to consider February's less than 30 days and 29 days in leap year. I spend my entire week trying to figure out how to do it.
In the end I want values in variable months_left, days_left, and hours_left. I tried modifying several date deference scripts but I couldn't get them to work as intended.

For my website i would like to display the age of my son in years,
months, days and hours.
For now i manage to get a result for totals. Like the total number of
days.
This is the beginning:
starttime = Date.parse("Aug 10,2003, 07:07")
sdt = new Date(starttime)
starttime= Math.ceil((starttime) / 1000 / 60 / 60 / 24 )
ndt = new Date()
y = sdt.getYear()
m = sdt.getMonth() + 1
d = sdt.getDate()
h = starttime

I'd like to add an automatically updating date field to a webpage. I found the below example on the internet which works brilliantly except I'd like an ordinal date (e.g. 1st, 2nd, 3rd, 4th)
instead of a cardinal date (e.g. 1, 2, 3, 4).
How could I do that with this small bit of javascript code?
<script language = "JavaScript">
var now = new Date();
var monNames = new
Array("January","February","March","April","May","June","July","August","September","October","November","December");
document.write("Last updated: " + now.getDate() + " " +
monNames[now.getMonth()] + " " + now.getFullYear());
</script>

I've written several scripts that have "while" blocks which increment a
date by one day if the date does not match one of a group of dates.
However, sometimes it apparently steps out out the while loop even
though my condition isn't met. Will work for a few loops then steps out
often.
Are there javascript "date" issues? I have also noticed different
results between Firefox and Internet Explorer.

I have two date fields (check in, check out) and "number of days"
field.
I want the script to calculate automatically the difference.
For example: I have defaults dates, and I want the script to put the
difference in "number of days" field. And if the user will change the
date, the number of days will change automatically.

I am using the standard datepicker but it has been highly modified to meet our needs. We have an option to select an entire week of dates:
[Code]..
What I'm trying to do is retrieve the first date of that selected week and the last date. All attempts have failed.

I'm trying to get a select box to automaticly populate the year ranging from 2008 to the current year + two years.Below I've put the code I've got so far which populates it with the current year plus two years so for example at the moment it shows 2009, 2010 & 2011. Next year it would show 2010, 2011, 2012 but I need it to start at 2008 so this year it would show 2008, 2009, 2011 & 2012 and next year 2008, 2009, 2011 & 2012.
Code:
<script type="text/javascript">
var year = new Date();
var nextYear = year.getFullYear()+1;
var nextYear2 = year.getFullYear()+2;

Here is my dilemna. I know HTML...and that's about it. So someone decided to give me a project that involves JavaScript. i've been reading tutorials online as much as possible...but I am a way beginner - be soft on me.
I have a form that had many drop down boxes. When a user selects a specific request type it populates the standard turnaround time in business days.
I need the "Standard Delivery Date" box to then autopopulate today's date plus the standard turnaround time that pops up in that field. How??
Here is a code that I have been working on - but so far it's not working.code...

I have the following script
function timeDifference(laterdate,earlierdate) {
var difference = laterdate.getTime() - earlierdate.getTime();
var daysDifference = Math.floor(difference/1000/60/60/24);
difference -= daysDifference*1000*60*60*24
document.write('difference = ' + daysDifference + ' day/s ');
}
var laterdate = ?;
var earlierdate = ?;
timeDifference(laterdate,earlierdate);
//--></script>
And would like to insert my datein and dateout values where the ? marks are above in red. I can call these variables into the form on the page using <%=Request("datein")%> but how do I call a variable into the script above?
