JavaScript 计算两个日期时间的时间差（YY-MM-DD HH:MM:SS）格式

getValue: function (time1,time2){
        var time1 = new Date(time1);    //转换为中国标准时间
        var time2 = new Date(time2);
        var time1 = time1.getTime();    //转换为时间戳
        var time2 = time2.getTime();
        var runTime = (time2 - time1) / 1000;       //开始得出时间差,然后计算
        var year = Math.floor(runTime / 86400 / 365);       
        runTime = runTime % (86400 * 365);
        var month = Math.floor(runTime / 86400 / 30);
        runTime = runTime % (86400 * 30);
        var day = Math.floor(runTime / 86400);
        runTime = runTime % 86400;
        var hour = Math.floor(runTime / 3600);
        runTime = runTime % 3600;
        var minute = Math.floor(runTime / 60);
        runTime = runTime % 60;
        var second = runTime;
        return year+'年,'+month+'月,'+day+'天,'+hour+'小时,'+minute+'分,'+second+"秒";
    },
