JavaScript - Date Comparison

I'm trying to get an emerge effect using javascript.
Here is my code
Code:

var t;
var s=0;
function emerge()
{
document.getElementById('my_span').style.opacity=s;
s=s+0.1;
t=setTimeout("emerge()",250);
if (s>1)
{
clearTimeout(t);
}
}
}

Works fine, does the things right.

But if I use this code, I get error.
Code:

var t;
var s=0;
function emerge()
{
document.getElementById('my_span').style.opacity=s;
s=s+0.1;
t=setTimeout("emerge()",250);
if (s==1)
{
clearTimeout(t);
}
}
}

The only thing I changed was comparison operator.

I tried to debug by adding alert box
Code:

var t;
var s=0;
function emerge()
{
alert(document.getElementById('my_span').style.opacity);
document.getElementById('my_span').style.opacity=s;
s=s+0.1;
t=setTimeout("emerge()",250);
if (s>1)
{
alert("Opacity set to max");
clearTimeout(t);
}
}
}

For some reason, it does not enter the if block if I use "==" operator & the alert box keeps coming up with "1" in it.
But works fine if I use ">" operator, enters the block and the last value it shows is "0.9".

Can anyone explain as to why this happens?

are these right ya?

'3' !=='smith' true
"test" == "test " true
'2' != 'smith' true
"exam" == "Exam" true
5 === "5 " false
"t" > "T" false
"y" >= "p" true
"Happy" == "happy " true

Hello everyone, for starters, I'm NOT working with arrays...with that being said, I need your help...I created a webform in PHP that retrieves values from a mysql table and displays them with its own mysqli_fetch_array command, in that loop it generates a textbox for each record...so far so good.

The created textbox (input element) is so that the user can type in the sequential number of how to reorder the records...example

Original Order of Records

1 Alpha 2 Bravo 3 Charlie 4 Delta 5 Echo

and user needs it to be in this order

User input sequential

2 Alpha 5 Bravo 1 Charlie 4 Delta 3 Echo

the new order of the records will be saved on a temporary table in the database before insertion on the main table, kinnda like a preview for the new order, something like this:

New Order of Records

1 Charlie 2 Alpha 3 Echo 4 Delta 5 Bravo

Now what I need is a function that helps me display a message if the user duplicates a sequential unique, if they type in number 1 in 2 or more records, when I hit the button for the preview I need it to loop through all the input boxes and check their values, compare it with the other inputs and determine if there are duplicates or not....if there're no duplicates, continue with PHP code.....if there are duplicates, display an error so the user seeks for the duplicate and change it (inputs left in blank will not be considered for the insertion in the preview table)

I already have this:

Code:

function checkall() {
	const t='texto';
	var contar=<?php echo $contar; ?>;
    var text = ""
    var conta = 1;
	var contas= conta+1;
	text = t+conta;
	texto = t+contas;
	//var curElement = document.activeElement.value;
	var cv=document.forms['OrderPreview'][text].value;
	//var cv=document.forms['OrderPreview'][curElement].value;
	do {
		//var cv=document.forms['OrderPreview'][text].value;
		if (document.forms['OrderPreview'][texto].value=="")
		{
			return;
		}
		if (cv==document.forms['OrderPreview'][texto].value)
		{
			alert("Something Bad"); 
		}
		conta++;
		contas++;
        text = t+conta;
		texto = t+contas;
    }
    while (conta<=contar)
}

Btw, the document.activeElement part of the code displays me "undefined" in the alert message, I still don't have a clue why, could you guide me with this please? I can't do but compare the 1st input with the rest of the fields, OR compare one field to the inmediate next field....it's driving me nuts

Any help will be truly appreciated, 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.

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?

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"

  				+	"</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,

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

I am delving into the coding world and while I understand the basic principle of cookies, conditional statements, arrays, etc... I am still learning how to properly implement them. Any asistance with the following situation would be greatly appreciated and help with my learning as I try to reverse engineer the logic. I have looked around the web and this forum with little success. If the situation below is too complicated, I would really appreciate even a shove in the right direction regarding the logic.

-----------------
How could I show a preset counter which counts up from a preset, beginning number toward a preset, end number? I imagine the increment and speed is set be the difference between the two numbers and a timeframe.

Assumptions:
I would rather not set the increment but edit the end number to show a steady increase. As I update that number, the increment adapts dynamically.

I would want the number/script to be useful, so it should not refresh to the beginning number on each page load (i.e. num=0). When a visitor comes to the page, it must seem like the counter has been steadily been increasing in their absence.

Coke or Pesi did something similar one time regarding cans sold to date (doubt it was plugged into a DB somewhere but rather based on a steady sales figure) and it was pretty cool.

All the best!

Hi,
i need to get the current date into some format so that it doesn't change?
here i have some code:
Code:

function printTime(){
var d=new Date();
var utc = d.toUTCString();
alert(utc);
}

for example this show for me: Mon, 26 Dec 2011 21:55:43 GMT

I would like to get this information again, lets say 5 minutes later - but i want the information to still read Mon, 26 Dec 2011 21:55:43 GMT not Mon, 26 Dec 2011 22:00:43 GMT for example

Any help greatly appreciated

I acquired this from joh6nn a year ago and now need one small addtion. This code produces the next meeting date based on one's local PC date. For the days, I need ST, ND, RD, TH added. For example, instead of "August 29", I need it to kick out "August 29th". Possible!? Code:
