转换标准时间为时间戳：

function getDateTimeStamp(dateStr){

 return Date.parse(dateStr.replace(/-/gi,"/"));

}

计算时间差：

 function getDateDiff(dateTimeStamp) {

             var minute =  * ;

             var hour = minute * ;

             var day = hour * ;

             var halfamonth = day * ;

             var month = day * ;

             var year = day * ;

             var now = new Date().getTime();

             var diffValue = now - dateTimeStamp;

             if (diffValue < ) { return; }

             var yearC = diffValue / year;

             var monthC = diffValue / month;

             var weekC = diffValue / ( * day);

             var dayC = diffValue / day;

             var hourC = diffValue / hour;

             var minC = diffValue / minute;

             if (yearC >= ) {

                 result = "" + parseInt(yearC) + "年前";

             }

             if (monthC >= ) {

                 result = "" + parseInt(monthC) + "月前";

             }

             else if (weekC >= ) {

                 result = "" + parseInt(weekC) + "周前";

             }

             else if (dayC >= ) {

                 result = "" + parseInt(dayC) + "天前";

             }

             else if (hourC >= ) {

                 result = "" + parseInt(hourC) + "小时前";

             }

             else if (minC >= ) {

                 result = "" + parseInt(minC) + "分钟前";

             } else

                 result = "刚刚";

             return result;

         }
