试试这个fiddle

function getCountOf( date1, date2, dayToSearch )
{

    var dateObj1 = parseDate(date1);
    var dateObj2 = parseDate(date2);

    var count = 0;

    var week = ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"];

    var dayIndex = week.indexOf( dayToSearch );

    while ( dateObj1.getTime() <= dateObj2.getTime() )
    {
       if (dateObj1.getDay() == dayIndex )
       {
          count++
       }

       dateObj1.setDate(dateObj1.getDate() + 1);
    }

    return count;
}
