  data() {
    return {
      form: {
        baselineDate: "",
        comparisonDate: "",
      },
      format: "yyyy/MM/DD",
      
    };
  },


methods:{

changeTime(date, type) {
      console.log(date);
      if (type == "comparisonDate") {
        this.form.comparisonDate = moment(date).format(this.format);
      } else {
        this.form.baselineDate = moment(date).format(this.format);
      }
    },},

坑： dom 中 value注意这里的是 “yyyy/MM/dd” 。moment 中在 format格式化的时候是 “yyyy/MM/DD”。”YYYY/MM/DD”也可以
