JavaScript - Edit Date Script

HI all,

maybe someone can help me.
I am using this script:

http://www.javascriptkit.com/script/...selector.shtml

on my site but as of Feb 1st 2012 the day of the week and the date do not match anymore. Feb 1st 2012 is not a thursday. Try example on site (link) to see what I mean.

Can anyone help me debug this?

Any help greatly appreciated
Dennis

What I am looking to do is auto-populate a number of forms based on what a user chooses as a starting date.

For example:

If a user enters 12/12/2009 I want the other fields to automatically populate with the next 2 weeks (12/13/2009, 12/14/2009, 12/15/2009 etc.)

Anyone have a useful script that I can use given that these fields are formatted as dates?

The idea is to save time by only having to fill in the first date in the timesheet.

I have been using the following script for some time and it has only just been made known to me that it fails on todays date ! not sure if this is the case for other days but the days of the week are all messed up and do not show correctly for a date in June 2011.


Code:

var ds_i_date = new Date();
ds_c_month = ds_i_date.getMonth() + 1;
ds_c_year = ds_i_date.getFullYear();

// Get Element By Id
function ds_getel(id) {
	return document.getElementById(id);
}

// Get the left and the top of the element.
function ds_getleft(el) {
	var tmp = el.offsetLeft;

Hi Script Experts

I am facing issue in below code for Brisilia time zone.(GMT-3). Issue comes in October month only. It is going tobig loop. I am not getting how Date object is behaving here.

Thanks in advance

Not sure if this is possible in javascript:

I'm looking for two different dates (bill date and due date) on an invoice that are captured by OCR. If one of them exists, but the other does not, I want the empty field to be 14 days before (or after) the other.

For example:
if the bill date is 7/27/2010 and the due date was not captured, I want to set the due date as 8/10/2010 (14 days after the bill date).

If the due date was captured as 8/10/2010, but the due date is blank, I want to assign the bill date as 7/27/2010 (14 days before the due date).

if both dates have values, do nothing.

Thanks.

Using Adobe Form Javascript validation, how would I do this code for Visual Basic in Javascript (non web)

Code:

If PurchaseDate.Value > Date Then
MsgBox ("PurchaseDate cannot be greater than Today's Date!")
Cancel = True
End If

Something along these lines but this isnt working:

Code:

If (PurchaseDate.Value > Date) Then 
{
app.alert ("Purchase Date cannot be greater than Today's Date!");
}

Thanks

Hello,

I really need your help with one.

How can I use the following code below to save the date from my popup window datepicker back into a var and relay it back onto its parent page?

I can't seem to figure this out:

Code:

<html>



<head>

<script>
	
	function open_cal() {
	

  var str_html	= 	""
  				+	"<!DOCTYPE html>\n"
				+	"<html lang=\"en\">\n"
				+	"<head>\n"
				+	"<meta charset=\"utf-8\">\n"
				+	"<title>CALENDAR</title>\n"
				+	"<link href=\"jq/jquery-ui.css\" rel=\"stylesheet\" type=\"text/css\">\n"
				+	"<script src=\"jq/jquery.min.js\" type=\"text/javascript\"></" + "script>\n" 
				+	"<script src=\"jq/jquery-ui.min.js\" type=\"text/javascript\"></" + "script>\n"
				+	"<script src=\"jq/datepicker.js\" type=\"text/javascript\"></" + "script>\n"
				+	"</head>\n"
				+	"<body>\n"
				+	"<div id=\"text\" style=\"font: bold 10pt Tahoma\">Enter Approval Date:</div>\n"
  				+	"<div id=\"datepicker\"></div>\n"
  				+	"</body>\n"
  				+	"</html>"
  				
var j = window.open("","CALENDAR","width=200,height=250,status=no,resizable=yes,top=200,left=200")
	j.opener = self;
	j.document.write(str_html);
}


</script>	
	

		
</head>

<body>

<input onclick="open_cal()" type="button" value="Open" name="B1">


</body>

</html>

Datepicker.js:
Code:

$(function() {
	
		$( "#datepicker" ).datepicker({ 
		
		dateFormat: 'dd/mm/yy',
		
		onSelect: function(dateText, inst) { 
		alert(dateText)
		window.close()
		
		} 
		
		})
		
		
		
		
});

Any help with this is greatly and mostly appreciated.

Thanks in advance,

Hi,

I've inherited a Form which calculates a future date based on a calculation and then inserts today's date and the future date into a database. The day part of the date is formatted as a number. This is fine, but up to 9 the numbers display in single figures with no leading zeros. I want them to display leading zeros (e.g. 01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11... 30, 31)

So;
1/12/2010 is NOT wanted
01/12/2010 IS wanted

The inherited code originally set the Month names as "Jan", "Feb" etc, and it was easy to kludge these to 01, 02... 12, but I suspect there's a more elgant solution to this as well, this bit of the code works so it's not as vital to neaten this but my database needs dd/mm/yyyy format (it's a third party email program).

Code:

 </script>

<script type="text/javascript">
var todaysDate = new Date();

function updateExpiryDate(){

	var weeklyMileage = document.getElementById('AvWeeklyMileage').value;
	var expiryDate;
	var weeks = 0;
	var expiryDateString = '';

	if (!isNaN(parseInt(weeklyMileage))){
		weeks = 700/weeklyMileage;
		expiryDate = new Date(todaysDate.getTime() + (1000 * 3600 * 24 * 7 * weeks));

		var expiryDateString = expiryDate.getDate() + '/' + getMonthString(expiryDate.getMonth()+1) + '/' + expiryDate.getFullYear();

		document.getElementById('expiryDate').innerHTML = expiryDateString;
		document.getElementById('ShoeExpiryDate').value = expiryDateString;
	} else {
		document.getElementById('ShoeExpiryDate').value = '';
		document.getElementById('expiryDate').innerHTML = 'Please enter a valid weekly average mileage'
	}

}

function getMonthString(monthNumber){
	var monthString = "";
	switch(monthNumber){
		case 1:
			monthString = "01";
			break;
		case 2:
			monthString = "02";
			break;
		case 3:
			monthString = "03";
			break;
		case 4:
			monthString = "04";
			break;
		case 5:
			monthString = "05";
			break;
		case 6:
			monthString = "06";
			break;
		case 7:
			monthString = "07";
			break;
		case 8:
			monthString = "08";
			break;
		case 9:
			monthString = "09";
			break;
		case 10:
			monthString = "10";
			break;
		case 11:
			monthString = "11";
			break;
		case 12:
			monthString = "12";
			break;
		default:
			// do nothing;
	}
	return monthString;
}

function setTodaysDate(){
	var todaysDateString = todaysDate.getDate() + '/' + getMonthString(todaysDate.getMonth()+1) + '/' + todaysDate.getFullYear();
	document.getElementById('todaysDate').innerHTML =todaysDateString;
	document.getElementById('DateOfPurchase').value = todaysDateString;

}

Can someone point me in the right direction please?

I have a drop down menu where people can select a month, day and year. Based on their selection, I want to show them an image.

If their selection is >= July 26, 2010 but <= July 25, 2011, show the red image;
If their selection is >= July 26, 2011 but <= July 25, 2012, show the white image;
If their selection is >= July 26, 2012 but <= July 25, 2013, show the blue image;
If their selection is >= July 26, 2013 but <= July 25, 2014, show the yellow image;

I don't know how to compare a selected date to a range of dates like this.
