nodejs 使用 js 模块的方法实例详解

module.exports = exports = function (){ };
module.exports = exports = function() {
 this.syncCompanyList = async function(developerName){
   await syncCompanyInfo(developerName);
 };
 async function syncCompanyInfo(developerName){
   // ...
 }
}

exports.funcName = function (){};
var getDistrictCode = function (districtName) {
  if (districtName) {
    for (let i= 0; i< DistrictInfo.length; i++) {
      let district = DistrictInfo[i];
      if (district[\"name\"] == districtName || district[\"aliasName\"] == districtName) {
        return district[\"code\"];
      }
    }
  }
  return \"\";
};
var getNormalDistrictName = function (districtName) {
  if (districtName) {
    if (districtName.indexOf(\'区\') > 0) {
      return districtName;
    }
    for (let i= 0; i< DistrictInfo.length; i++) {
      let district = DistrictInfo[i];
      if (district[\"name\"] == districtName || district[\"aliasName\"] == districtName) {
        return district[\"name\"];
      }
    }
  }
  return \"\";
}
// 设置导出的方法及属性
exports.getDistrictCode = getDistrictCode;
exports.getNormalDistrictName = getNormalDistrictName;

const company = require(\"./company\");
// ...
// 实例化一个 company 对象
var comp = new company();
// 调用 company 里的 syncCompanyList 
comp.syncCompanyList ();

const districtUtil = require(\"./utils/districtUtil\");
// ...
// 调用 districtUtil 里的 getDistrictCode
let districtNme = districtUtil.getDistrictCode(\'districtName\');
