我想查找两个日期之间存在多少天、几个月和几年。这是我目前正在使用的方法

 $scope.getForcastPeriod = function(newValue){

        var CalcEnddate;
        var forecastDays;



            var CalcEnddate   = new Date($scope.forecastObj.paramObj.enddate);
            var visualEnddate = new Date($scope.visualDate.enddate);

            var diff = new Date(visualEnddate - CalcEnddate);

            var years = (diff.getFullYear() - 1970);
            var months = (diff.getMonth()) + (12 * years);
            var days = (diff.getDate()) + (365 * years);

            var months = $scope.monthDiff(CalcEnddate,visualEnddate);


            if($scope.forecastObj.paramObj.interval == "Yearly"){
                forecastDays = years+1;
            }
            else if($scope.forecastObj.paramObj.interval == "Monthly"){
                forecastDays = months+1;
            }
            else if($scope.forecastObj.paramObj.interval == "Daily"){
                forecastDays = days;
            }

            return forecastDays ;

    }

但它给了我错误的结果。

例如，对于 CalcEnddate = "December 30, 2012"和visualEnddate = "March 31, 2013"它返回我的号码 months = 2 , days = 2 。

请帮忙。

你可以简单地这样做，

var date1 = new Date("12/30/2012");
var date2 = new Date("3/31/2013");
var timeDiff = Math.abs(date2.getTime() - date1.getTime());
var diffDays = Math.ceil(timeDiff / (1000 * 3600 * 24)); 
var diffmonths = Math.ceil(timeDiff / (1000 * 3600 * 24 *12)); 
alert("DAYS"+ " " +diffDays);
alert("MONTHS"+ " " + diffmonths);
