vue中使用elm表单的自定义校验规则

  data() {
    var checkAge = (rule, value, callback) => {
      // console.log(value, "输入的");
      // console.log(this.da, "最大的");
      // console.log(this.xiao, "最小的");
      let value1 = Number(value);
      let xiao1 = Number(this.xiao);
      let da1 = Number(this.da);
      if (value1 > da1 || value1 < xiao1) {
        return callback(new Error("请输入价格区间内的金额"));
      } else {
        callback();
      }
    };
    return {
      xiao: "",
      da: "",
      rules: {
        price: [
          {
            validator: checkAge,
            trigger: "blur"
          }
        ]
      }
    };
  },



   /* 保存编辑 */
    save(form) {
      this.$refs[form].validate(valid => {

          this.loading = true;

            type: 1,

          };
          this.$http
            .post("admin-api/member-order/add", info)

              } else {

              }
            })
            .catch(e => {
