JavaScript - How To Retrieve Just The Date

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.

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?

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,

Hello
I am trying to iterate out the values of an xml file. I have got the file to load though I have not yet been able to extract the values.
Considering that theXml is an xml file and 'coords' are tags containing a coordinate how would I extract the value. Here is the code I am using
Code:

var coordTags = theXml.getElementsByTagName( 'coords' );
			var len =coordTags.length;///this works
			var coord =coordTags[0].value;///this doesn't work
                        var coord =coordTags[0].text;///this doesn't work
                        var coord =coordTags[0].innerText;///this doesn't work


	  		parent.document.receiver.theres.value = coord;

I am sure for some of you this is a really simple question so please someone help!!

Hello,

I'm very new to JavaScript as well as this forum, so apologies if I mess up somewhere.

Okay, so I have a HTML doc with a JavaScript attached to it, and in the HTML I have a checkbox. All I want to do is to pass the checkbox data to Javascript as a true/false.

Okay, so below is my HTML:

Code:

<head>
<script type="text/javascript" src="java.js"></script>
</head>

<body>
<input id="toggle" type="checkbox" value="">
</body>

And this is my JS:

Code:

var toggleData = false;

Now where do I go from here? I tried using getElementByld('toggle'); But no result.

I sure would appetite some help here.

Thanks

Hi, I know there are several ways to do this- but which way is best practice?

I can access a variable from one function by making it a global variable, but I read that this isn't the most ideal way, and is a last resort. So for example if I have this:

Code:

function num1(){
  var firstNum = 35;
     return firstNum;
}

function num2(){
 var secNum = 52;
    return secNum;
}

function addNums(x,y){
 var f = num1(x);
 var s = num2(y);
    var total = f + s;
    alert(total);
}

Then I call this function with a button.

Now, I know this works, but it doesn't seem like a very good way to do what I'm after. Or is it?
Any help/ tips would be great.

edit: The idea is that the functions won't just return a single value and that's it. They will return a users choice in a given scenario, so they might return the user's
age from the first function, then their location in the next etc etc, then I want to use this information in a separate function.

Hi,

I have several input text boxes in a <FIELDSET> tag.

I would like to load id attributes of the <FIELDSET> tag into an array and then process the array.

My code example is below my signature.

Thank You in Advance for Your Help,

  </fieldset>

<button type="button" onclick="DisplayDetails('name1')">Click Me!</button> 

</html>

So, this is my last problem. If I can nail this, then the website will be completely AJAX driven, and will be spectacular.

It took me a while to figure out just how to ask the question. lol

Now it is really simple.

1) When I hit the button, in the simplified example below, the website sends a code to the server.
2) The server then re-writes the "xyz.js" JavaScript file with a new array of values.

Is there any way to re-retrieve that JavaScript file, from the server to make it the current "xyz.js" rather than the old one that loaded on the client originally.

I can get a new XML data file and re-submit that to the website, but how do I re-retrieve the new JavaScript code?

Code:

<html>
<head>
<script src="xyz.js" type="text/javascript"></script>
</head>
<body>
<button onclick="onload();">Change</button>
</body>
</html>

Good morning!
I am Brazilian, sorry if there is a clerical error because I used the Google translator.
I'm having trouble recovering in JS content of the columns of a <TABLE>.
I did many searches but found nothing that could help me.
I appreciate any help.

Thank you!
