Validation of Start Date and End Date using JavaScript

I was trying to validate start date and end date. If user select the end date which is less than start date then a warning message will display which tell that End date should be greater than start date

for that i have used this Code:

[code]

function ValidateDate()

{

var StartD = document.getElementById('').value; 

var EndD = document.getElementById('').value;

var endDate = new Date(EndD ); 

var startDate= new Date(StartD );

if(StartD != '' && EndD != '' && startDate > endDate )

{

 alert("Check out date should be greater than check In Date.");

 return false;

}

if(StartD == EndD )

{

alert("Check out date should be greater than check In Date.");

return false;

}

}

[/code]

and call this function onclientclick of button event.
