包含两头的日期计算在内 : <script type="text/javascript"> function weekendBetween(dtStart, dtEnd) { if (typeof dtEnd == 'string' ) dtEnd = StringToDate(dtEnd); if (typeof dtStart == 'string' ) dtStart = StringToDate(dtStart); var days = parseInt((dtEnd - dtStart) / 86400000); var adds = 0; var m = (days+ dtStart.getDay() +1) % 7; if(m > 0) adds = m; if(m >2) adds = 2; var redu = 0 if(dtStart.getDay() > 0) redu = 2; if(dtStart.getDay() ==1) redu =1; var subtotal = parseInt((days + dtStart.getDay() +1)/7)*2; return subtotal - redu + adds; } function StringToDate(DateStr) { var converted = Date.parse(DateStr); var myDate = new Date(converted); if (isNaN(myDate)) { var arys= DateStr.split('-'); myDate = new Date(arys[0],arys[1],arys[2]); } return myDate; } alert("2-1~~~~2-18"); alert(weekendBetween(new Date(2008,2,1), new Date(2008,2,18))); alert("2-1~~~~2-15, 字符型参数"); alert(weekendBetween("2008-2-1","2008-2-15")); alert("2-1~~~~2-16, 字符型参数"); alert(weekendBetween("2008-2-1","2008-2-16")); alert("2-1~~~~2-17, 字符型参数"); alert(weekendBetween("2008-2-1","2008-2-17")); alert("2-3~~~~2-16, 字符型参数"); alert(weekendBetween("2008-2-3","2008-2-16")); </script>
