标准时间格式和long格式的转换

1、将long时间格式转化为几秒前

/* 时间 */
function getDateDiff(hours){
    var minute = 1000 * 60;
    var hour = minute * 60;
    var day = hour * 24;
    var halfamonth = day * 15;
    var month = day * 30;
    var now = new Date().getTime();
    var diffValue = now - hours;
    if(diffValue < 0){return;}
    var monthC =diffValue/month;
    var weekC =diffValue/(7*day);
    var dayC =diffValue/day;
    var hourC =diffValue/hour;
    var minC =diffValue/minute;
    if(monthC>=1){
        result="" + parseInt(monthC) + "月前";
    }
    else if(weekC>=1){
        result="" + parseInt(weekC) + "周前";
    }
    else if(dayC>=1){
        result=""+ parseInt(dayC) +"天前";
    }
    else if(hourC>=1){
        result=""+ parseInt(hourC) +"小时前";
    }
    else if(minC>=1){
        result=""+ parseInt(minC) +"分钟前";
    }else
        result="刚刚";
    return result;
}
function getDateTimeStamp(dateStr){
    return Date.parse(dateStr.replace(/-/gi,"/"));
}

//获取当前时间
function getNowFormatDate() {
    var date = new Date();
    var seperator1 = "-";
    var seperator2 = ":";
    var month = date.getMonth() + 1;
    var strDate = date.getDate();
    if (month >= 1 && month <= 9) {
        month = "0" + month;
    }
    if (strDate >= 0 && strDate <= 9) {
        strDate = "0" + strDate;
    }
    var currentdate = date.getFullYear() + seperator1 + month + seperator1 + strDate
        + " " + date.getHours() + seperator2 + date.getMinutes()
        + seperator2 + date.getSeconds();
    return currentdate;
}


//调用
var hours = JSON.stringify(data[0].inputtime.time);
$('#hour').text(getDateDiff(hours));

2、将long时间格式转化为标准格式

//将long时间格式转化为标准格式
    function dateFormatUtil(longTypeDate){
        var dateTypeDate = "";
        var date = new Date();
        date.setTime(longTypeDate);
        dateTypeDate += date.getFullYear();   //年
        dateTypeDate += "-" + getMonth(date); //月
        dateTypeDate += "-" + getDay(date);   //日
        return dateTypeDate;
    }

    //返回 01-12 的月份值
    function getMonth(date){
        var month = "";
        month = date.getMonth() + 1; //getMonth()得到的月份是0-11
        if(month<10){
            month = "0" + month;
        }
        return month;
    }

    //返回01-30的日期
    function getDay(date){
        var day = "";
        day = date.getDate();
        if(day<10){
            day = "0" + day;
        }
        return day;
    }

//调用
dateFormatUtil(data[0].inputtime.time)
