var givenStartDate = $('#startDate').val();
        alert('START DATE'+givenStartDate);
        var givenEndDate = $('#endDate').val();
        alert('END DATE'+givenEndDate);
        var date = new Date();
        var month = date.getMonth()+1;
        var day = date.getDate();
        var currentDate = date.getFullYear() + '-' +
            (month<10 ? '0' : '') + month + '-' +
            (day<10 ? '0' : '') + day;
        if(givenStartDate < currentDate || givenEndDate < currentDate)
         { 
        $("#updateButton").attr("disabled","disabled"); 
         }
         if(givenStartDate < currentDate && givenEndDate > currentDate)
            {
            $("#updateButton").attr("enabled","enabled");
            }
         if(givenStartDate > currentDate || givenEndDate > currentDate) { 
        $("#updateButton").attr("enabled","enabled"); 
         }

Try this. If any mistake, please correct me :) Thanks all.
