Most of the time we need to set datatime field value in crm, but problem is that ms crm datetime file format is different from sql server date format so i have written a some js to get date part from sqlserver datetime field.
we can pass datetime value to this function and it will return date part from datetime value.
function GetDate(strCrmFormatDate)
{
var newDate=new Date();
var indexofT=strCrmFormatDate.indexOf(“T”);
var strdatepart=strCrmFormatDate.substring(0,indexofT);
var month=strdatepart.substring(5,7);
var year=strdatepart.substring(0,4);
var day=strdatepart.substring(8);
if(month.substring(0,1)==’0′)
{
month=month.substring(1);
}

newDate.setMonth(parseInt(month)-1);
newDate.setFullYear(year);
newDate.setDate(day);
return newDate;
}
