Date Format using javascript

Below is the code to change different format of date using a javascript. If you have a date in a string format, you can use the string functions of javascript to give any format you want.

I have a date format which is in m-d-yyyy format and I want to change it in dd-mm-yy format.

<script language="javascript" type="text/javascript">

$(document).ready(function()

{ 

var vArticledate=$("#datefield").text();

var dt = vArticledate.split("/");

var iMonth=dt[0];

if(iMonth.length<2)

  iMonth="0"+iMonth;

var iDay=dt[1];

if(iDay.length<2)

iDay="0"+iDay;

var iYear=dt[2];

iYear = iYear.substring(iYear.indexOf("0")+1,iYear.length);

document.getElementById('datefield').innerHTML = "<b>"+iDay +"-"+iMonth+"-"+iYear+" </b>";

}) 

</script>
