To compare dates with time in Javascript we need to pass them in Date object as "yyyy/mm/dd HH:mm" format for e.g. like "2014/05/19 23:20" . Then you can just compare them with > or < less then symbol according to your business rule. Please see given below code for more understanding.

$(function () {

    $("input#Submit").click(function () {
        var startDateTime = $("input[name='StartDateTime']").val();
        var endDateTime = $("input[name='EndDateTime']").val();

        var splitStartDate = startDateTime.split(' ');
        var splitEndDate = endDateTime.split(' ');

        var startDateArray = splitStartDate[0].split('/');
        var endDateArray = splitEndDate[0].split('/');

        var startDateTime = new Date(startDateArray[2] + '/ ' + startDateArray[1] + '/' + startDateArray[0] + ' ' + splitStartDate[1]);
        var endDateTime = new Date(endDateArray[2] + '/ ' + endDateArray[1] + '/' + endDateArray[0] + ' ' + splitEndDate[1]);

        if (startDateTime > endDateTime) {
            $("#Error").text('Start date should be less than end date.');
        }
        else {
            $("#Error").text('Success');
        }
    });

});
