跟当前时间比较，显示时间差距？

醉***o 分类：Html5 人气：1331 回帖：4 发布于6年前收藏

如图：

将日期跟当前时间比较，并显示相差的时间如图展示，想封装一个方法，但是具体不知道该怎么弄好，求大神指点迷津。

自己在各路大神点思路下，自己给弄了一个，如下：

//与当前时间比较
function getDate(time){
    var str = time;
    //将字符串转换成时间格式
    var timePublish = new Date(str);
    var timeNow = new Date();
    var minute = 1000 * 60;
    var hour = minute * 60;
    var day = hour * 24;
    var month = day * 30;
    var diffValue = timeNow - timePublish;
    var diffMonth = diffValue / month;
    var diffWeek = diffValue / (7 * day);
    var diffDay = diffValue / day;
    var diffHour = diffValue / hour;
    var diffMinute = diffValue / minute;
   
    if (diffValue < 0) {
       console.log("错误时间");
    }
    else if (diffMonth > 3) {
        result = timePublish.getFullYear()+"-";
        result += (timePublish.getMonth() + 1) + "-";
        result += timePublish.getDate();
        // $.toptips(result);
    }
    else if (diffMonth > 1) {
        result = parseInt(diffMonth) + "月前";
    }
    else if (diffWeek > 1) {
        result = parseInt(diffWeek) + "周前";
    }
    else if (diffDay > 1) {
        result = parseInt(diffDay) + "天前";
    }
    else if (diffHour > 1) {
        result = parseInt(diffHour) + "小时前";
    }
    else if (diffMinute > 1) {
        result = parseInt(diffMinute) + "分钟前";
    }
    else {
        result = "刚刚";
    }

    return result;
}

直接给你代码就没意思了，给你提供个思路吧
主要说下是怎么得出这个时间差距的，通过前后两个时间戳相减得来的，比如说我要算 1506565621 这个时间戳和当前时间 1506565623 差距，直接把这个两个时间戳相减得出的就是2，即为2秒前

依照这个思路，时间戳都是基于秒数来递增的，60s=1min，如果相差为60就为1分钟前，依次类推，一小时等于多少秒，将两个时间戳相减得到的数依次除以分钟、小时、天数对于的秒数，就可以判断为几秒前或者是几分钟前

考虑下年、月、日、时、分的情况，主要是通过对比时间，分成六个级别【年、月、日、时、分、1分钟内】，哪个级别匹配到了就拿出结果即可：

function diffTime(dataStr){
    var nowDate = new Date().getTime(),
        oldDate = new Date(dataStr).getTime(),
        diffTime = parseInt((nowDate - oldDate)/1000,10),
        oneMinute = 60,
        oneHour = 60 * oneMinute,
        oneDay = 24 * oneHour,
        oneMonth = 30 * oneDay,
        oneYear = 12 * oneMonth,
        compareArr = [oneYear,oneMonth,oneDay,oneHour,oneMinute],
        postfix = ['年前','个月前','天前','个小时前','分钟前','1分钟内'],
        diffYear,diffMonth,diffDay,diffHour,diffMinute,len=5;
    for(var i =0; i< len ;i++){
        var diff = Math.floor(diffTime/compareArr[i]);
        if(diff > 0){
            return diff + postfix[i];
        }
        else if(i === len -1 && diff === 0){
            return postfix[len];
        }
    }
}
