在引用了Moment.js后
formatDate(){returnfunction(val){letthat=this;this.$moment.lang("zh",{calendar:{lastDay:"[昨天]HH:mm:ss",lastWeek:"MM月DD日HH:mm:ss",nextDay:"[明天]HH:mm:ss",nextWeek:"MM月DD日HH:mm:ss",sameDay:"[今天]HH:mm",sameElse:function(now){if(that.isThisYear(now,val)){return"MM月DD日HH:mm:ss";}else{return"YYYY年MM月DD日HH:mm:ss";}}},});returnthis.$moment(val).calendar();};},//判断时间是否是今年isThisYear(now,val){if(val){returnthis.$moment().year()===newDate(val).getFullYear()}},使用方法：formatDate（time）
