assign date field to ddmmyy variables

Hi Guys,

I have some code which takes the current date and splits it into dd, mm and yy variables.

var today = new Date();
var dd = today.getDate();
var mm = today.getMonth()+1;
var yyyy = today.getFullYear();if(dd<10){dd='0'+dd}if(mm<10){mm='0'+mm}
this.rawValue = "Text, " + dd+ "-" + mm + "-" + yyyy; 

I need to pass this a date from a date field instead of taking to days date but I cannot get it working.

var today = this.parent..DateTimeField2.rawValue;
var dd = today.getDate();
var mm = today.getMonth()+1;
var yyyy = today.getFullYear();if(dd<10){dd='0'+dd}if(mm<10){mm='0'+mm}
this.rawValue = "TEXT, " + dd+ "-" + mm + "-" + yyyy; 

Any help would be appreciated.

Thanks!
