关于闭包与面向对象的问题

Question

封装了一个方法，用了两种方式，效果是有了，就是不知道对不对，能不能这样写，本人新手，还很迷糊，还想问一下，这两种可否在项目大量使用，利弊是什么//方式一export function getData(resId,project){   this.paramObj = {      resId:resId,      requestData: {        project: project,      }    };}//调用 let Person=new way.getData(this.resId, this.$store.state.project) ll.initialize(Person.paramObj,this);//方式二export function format(resId,project){  return function (){    let paramObj = {      resId: resId,      requestData: {        project: project      }    };    return paramObj  }}//调用  let newDel=way.format(this.resId, this.$store.state.project)  ll.initialize(newDel(),this);

Answer 1

楼主更像是在封装参数

ES6的话可以这么写

class Params{

    constructor(resId,project){

        this.resId = resId;

        this.project = {

            project: project

        };

    }

}

let resId = 2;

let project = '12345678'

let param = new Params(resId,project);

console.log(param.resId,param.project);

console.log(param);

ES5的话可以这么写

function Project(project){

    this.project = project;

}

function Params(resId,project){

    this.resId = resId;

    this.project = new Project(project);

}

var resId = 2;

var project = '12345678'

var param = new Params(resId,project);

console.log(param.resId,param.project);

console.log(param);

明明一句话就可以搞定，还非要搞个函数，又是new 又是return function；这么折腾干嘛
