安装依赖

npm install element-china-area-data -S
cnpm install element-china-area-data -S

引用

import { provinceAndCityData, regionData, provinceAndCityDataPlus, regionDataPlus, CodeToText, TextToCode } from 'element-china-area-data'；

1. provinceAndCityData是省市二级联动数据（不带“全部”选项）
2. regionData是省市区三级联动数据（不带“全部”选项）
3. provinceAndCityDataPlus是省市区三级联动数据（带“全部”选项）
4. regionDataPlus是省市区三级联动数据（带“全部”选项）
5. “全部"选项绑定的value是空字符串”"
6. CodeToText是个大对象，属性是区域码，属性值是汉字 用法例如：CodeToText[‘110000’]输出北京市
7. extToCode是个大对象，属性是汉字，属性值是区域码
   用法例如：TextToCode[‘北京市’].code输出110000,TextToCode[‘北京市’][‘市辖区’].code输出110100,TextToCode[‘北京市’][‘市辖区’][‘朝阳区’].code输出110105

CodeToText的使用

getCodeToText(codeStr, codeArray) {
      if (null === codeStr && null === codeArray) {
        return null;
      } else if (null === codeArray) {
        codeArray = codeStr.split(",");
      }

      let area = "";
      switch (codeArray.length) {
        case 1:
          area += CodeToText[codeArray[0]];
          break;
        case 2:
          area += CodeToText[codeArray[0]] + "/" + CodeToText[codeArray[1]];
          break;
        case 3:
          area +=
            CodeToText[codeArray[0]] +
            "/" +
            CodeToText[codeArray[1]] +
            "/" +
            CodeToText[codeArray[2]];
          break;
        default:
          break;
      }
      return area;
    }
