JavaScript - List Box Durations To Calculate Date

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.

I want to do a calculation between selectbox values. The problem with my code is that the first part of the calculation only gives me 0, which Motherboard value*quantity. the second part works fine which Chassis*quantity. My formulas is motherbord*Quanity+chassis*quantity.

Code:

function calculate() {   
  var parsedMotherboard = parseFloat(document.calcform.Motherboard.value || 0);     
var parsedQuantity = parseFloat(document.calcform.Quantity.value || 0);     var parsedChassis = parseFloat(document.calcform.Chassis.value || 0);     
var parsedQuantity1 = parseFloat(document.calcform.Quantity1.value ||0);      
document.calcform.total.value = (parsedMotherboard * parsedQuantity + parsedChassis * parsedQuantity1); }

PHP Code:
echo "<tr><td align='left' width='90%'>";

$result = mysql_query("SELECT Motherboard_Part_Number, Motherboard_Name, Motherboard_Price FROM Motherboard ") 
or die(mysql_error());  
echo '<select id="Motherboard" class="SelectClass" name="Motherboard" ONCHANGE="calculate()">';

Hello.

I wonder is there any javascript to calculate IP length

For example I have

Start ADDR:

VLAN_ADDR which is:

10.52.28.0

Stop ADDR:

VLAN_LAST which is

10.52.29.254

As I know:result is 512

or another example:

Start ADDR:

VLAN_ADDR which is:

10.52.64.11

Stop ADDR:

VLAN_LAST which is

10.52.64.15

As I know:result is 5


How to count it in javascript code ?
Results are "numbers"

Best regards

Leos.

I'm working on creating a custom calculator to determine the amount of money / credits users may earn from referrals. I've tested onChange, and it will work only when I have changed to a new field or clicked off that field. How do I make this calculate live?

So if the current value is 5 and I change it to 6, it will automatically recalculate the new value.

You can see what I'm working on he

http://sheetmusichaven.com/admin/mys...calculator.php

Note: The one I'm testing is the 1st Level field. For now i'm just having it display the date.

I have tried many time to make the calculation to appear at the total text box. however, I fail to find where the problem is. Please help me..

here is my coding..

Hi there,
I'm new here in this forum and I've registered to ask a question about JavaScript or Jquery. I don't know which to use.

I have my code php like that:
<?php
//Get the data from system and return in EU format
function ShowDate() {
$Date = date("d"."/"."m"."/"."Y");
return $Date;
}
//Get the time from system
function ShowTime() {
$Time = date("H".":"."i");
return $Time;
}
?>

Now I have two input box

<html>
<head>
</head>
<body>
Type the date:<input name="txtdate" type="text" class="input" id="txtdate" title="e.g dd/mm/yyyy" value="<?php echo ShowDate(); ?>" size="9" maxlength="10">
<br>
Type the time:<input name="txttime" type="text" id="txttime" value="<?php echo ShowTime(); ?>" size="5" maxlength="5">
<br>
London: Friday May 21 2010 05:12:00 <br>
New York: Friday May 21 2010 00:12:00<br>
Hong Kong: Friday May 21 2010 12:12:00<br>
Tokyo: Friday May 21 2010 13:12:00<br>
</body>
</html>

So.... the important is the user can interactive with the date. If I change the date or time all this values will be change as well.
Someone knows how can I do this?
The field txtdate I will get from a calendar plugin (javascript) that I already put in my code.

Thank you for your help.

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,

Cheers,

Hi,
I need to add days to a date in javascript,
My requirement is as follows:
Date is coming from a textbox.
eg:- 26/07/2010

days from this statement

var day1=document.getElementById('<%=HiddenDate.ClientID %>').value;

an eg:- if the date is 28/01/2012 and days Needed to be added=5
the added date should be 02/02/2012.
Can anybody help me?

Thanks
Jamuna

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.

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
