Jquery 时间比较

 

 var t1 = $("#t1").val(); //获取起始时间
            var t2 = $("#t2").val(); //获取结束时间
            if (t1 != null && t2 != null && t1 != "" && t2 != "") {
                var qssj = new Date(t1.replace("-", "/"));
                var jssj = new Date(t2.replace("-", "/"));
                var day = DateDiff_Day(qssj, jssj);
                alert("起始时间：" + qssj + "\n结束时间：" + jssj);
                alert(iHours);
            }

 

  //两个时间进行比较(按小时)
        function DateDiff_hour(s1, s2) {
            var iHours = parseInt((s2 - s1) / (1000 * 60 * 60));
            return iHours;  //iHours大于0表示s1大于s1
        }
        //两个时间进行比较(按日)
        function DateDiff_Day(s1, s2) {
            var day = s2.getDate() - s1.getDate();
            return day;   //day大于0表示s1大于s1
        }
