工具函数：

export default {
  methods: {
    getDay(day) {
      var today = new Date();
      var targetday_milliseconds = today.getTime() + 1000 * 60 * 60 * 24 * day;
      today.setTime(targetday_milliseconds); //注意，这行是关键代码
      var tYear = today.getFullYear();
      var tMonth = today.getMonth();
      var tDate = today.getDate();
      tMonth = this.doHandleMonth(tMonth + 1);
      tDate = this.doHandleMonth(tDate);
      return tYear + "-" + tMonth + "-" + tDate;
    },
    doHandleMonth(month) {
      var m = month;
      if (month.toString().length == 1) {
        m = "0" + month;
      }
      return m
    }
  }
}

使用：

getDay(0) //今天
getDay(-1) //近一天
getDay(-7) //近一周
getDay(-30) //近一个月
