推荐答案

Hi, Please try following way
<script type="text/javascript">
function CompareDate()
 {
     var fromDate = documet.getElementById('txtFromDate').value;
     var toDate = documet.getElementById('txtToDate').value;
     var endDate = new Date(toDate);
     var startDate = new Date(fromDate);

     if(fromDate!=''&&toDate!=''&&startDate>endDate)
         {
              alert('end date should be greater than or equal to start date');
              documet.getElementById('txtToDate').value="";
              return false;
         }
       else if(fromDate=='')
        {
           alert('Please enter start date!');
           return false;
        }
        else if(toDate=='')
        {
           alert('Please enter end date!');
           return false;
        }
   }
</script>
