ddmmyyyy to mmddyyyy in Javascript

**millsy007** · 03-06-2009, 09:18 PM

I have recently changed my page so my date that is held in a textbox is in the European Format, ie DD/MM/YYYY

The problem is all of my other javascript functions expect it in the 'normal' format.
Is there a way I can change the format I now have it in back, so:
datevariable = document.getElementById('date').value;
switches back from dd/MM/yyyy to MM/dd/yyyy

Hi I try to do this within my function:

Code:

var tmp = document.getElementById('date').value;
var tmp = ddmmyyyy.split('/');
var date = tmp[1]+'/'+tmp[0]+'/'+tmp[2];

But it doesnt work ?

Can we see all the code? Also are you using PHP or JS to generate the time? (is it dynamic?)

Here is a demo using JS

Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
	<head>
		<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
		<title>Untitled Document</title>
		<style type="text/css">
		</style>
		<script type="text/javascript">
			function changeDate(){
				var currentDate= document.getElementById('date').value; //Extracting the date value in dd/mm/yyyy format from the mentioned text box
				alert('The original value: ' + currentDate); //Printing the extracted date value before making the change
				var newDate = currentDate.split('/'); //Splitting the extracted date value using the delimiter /, which is the seperator used in the date value			
				currentDate = newDate[1] + "/" + newDate[0] + "/" + newDate[2];//Constructing a new date value (string) using the splitted values.
				alert('Value after the change : ' + currentDate);//Showing the new date value.
			}			
		</script>
	</head>
	<body>
		<form name="f1">
			<input id="date" type="text" name="dte" value="07/03/2009" />
			<input type="button" id="click" value="click"/>
		</form>
		<script type="text/javascript">
			document.getElementById('click').onclick = changeDate; //Event handler assignment			
		</script>
	</body>
</html>

Hope this helps.

Assuming the rest of your code is correct, ddmmyyyy is undefined and you've declared tmp twice, which would overwrite the first instance of tmp, try:

Code:

var tmp = document.getElementById('date').value.split('/');
var date = tmp[1]+'/'+tmp[0]+'/'+tmp[2];
