省市区你又来辣!!!+发送搜索条件判空处理

0. 缘起

today, afraid by 省市区!!!

出现了1个阴间问题,只要我改了省,之后的市和区就无法选中!!!原因就是我watch省,省改变就把市区都变成'',但初始化的时候没有初始化这三个,所以就出现了很阴间的情况!!!

1. 关键

      this.form = {
        industryType: "",
        industryTypeMedium: "",
        industryTypeLimit: "",
        regionProv: "",
        regionCity: "",
        regionArea: "",
      }

这部分很关键,如果不初始化,就会出现上述的阴间情况!!!

2. 发送时进行判空处理

    searchTable() {
        // Important 
      let form = {},
        self = this;
      Object.keys(this.form).forEach((key) => {
        if (!isEmpty(key)) {
          form[key] = this.form[key];
        }
      });
        // RegionAncestors Special 
      if ((form.regionProv ?? "") !== "") {
        form.regionAncestors = getAddress();
      }

      this.$emit("deliver-search", form);

      function isEmpty(keyName) {
        return self.form[keyName] === "";
      }

      function getAddress() {
        let prov = form?.regionProv;
        let city = form?.regionCity;
        let area = form?.regionArea;
        let str = ",";
        if ((area ?? "") !== "") {
          return prov + str + city + str + area;
        } else {
          if ((city ?? "") !== "") {
            return prov + str + city;
          } else {
            if ((prov ?? "") !== "") {
              return prov;
            } else {
              return "";
            }
          }
        }
      }
    },
