如何将参数从一个页面函数传递到另一个页面 class Javascript/Node js 中的函数

Question

我想将参数从我的 app.js 页面传递到包含 class 函数的另一个页面 User.js，但我得到的只是 undefined 值。我正在尝试通过询问者的选择，但它没有通过。

User.js

class User{
  setUser(name){
    let userThing= fname(name);
    ...
    ...
    return userThing
  }

  getUser(){
    ...
    ...
    return
  }
}

module.exports.User=User;

app.js

const { Command } = require("@oclif/command");
const inquirer = require("inquirer");
const config = require("./User.js");

class RegionCommand extends Command {
 async run(){
   inquirer
   .prompt({
      type: "list",
      name: "test",
      message: " Select Nickname: ",
      default: false,
      choices: ["Tom", "Jerry"],
      })
      .then((answers) => {
        var selectedName=answers.test;
        // var nameDetails= this.config.User.setUser(selectedName); I tried this method too but still not working.
        var nameDetails= config.User.setUser(selectedName);
      });
 }
}

如何将查询值 app.js 传递给 user.js？

您正在尝试像调用静态函数一样调用普通函数。您首先需要创建一个 class 实例！

const { Command } = require("@oclif/command");
const inquirer = require("inquirer");
const { User } = require("./User.js");

class RegionCommand extends Command {
 async run(){
   inquirer
   .prompt({
      type: "list",
      name: "test",
      message: " Select Nickname: ",
      default: false,
      choices: ["Tom", "Jerry"],
      })
      .then((answers) => {
        var selectedName=answers.test;
        const user = new User(); // create an instance of the class "User"
        var nameDetails= user.setUser(selectedName);
      });
 }
}
