javascript - 如何一次定义很多变量

Question

我正在开发一个项目，想知道是否有一种简单的方法可以定义和使用多个变量，而无需编写一堆代码。

所以我一直在做的只是像这样定义它们:

var Kahoot = require("kahoot.js-updated");
var client1 = new Kahoot;
var client2 = new Kahoot;
var client3 = new Kahoot;
var name = "example";
var id = "12345";

然后像这样使用它们:

client1.join(id , name+"1").then(() => {client1.on("question", question => {});client1.on("questionStart", question => {question.answer(randomAnswer());})});
client2.join(id , name+"2").then(() => {client2.on("question", question => {});client2.on("questionStart", question => {question.answer(randomAnswer());})});
client3.join(id , name+"3").then(() => {client3.on("question", question => {});client3.on("questionStart", question => {question.answer(randomAnswer());})});

这很好用，但我必须手动复制和粘贴，然后替换变量号。有什么更简单的方法可以做到这一点而无需一遍又一遍地复制粘贴？

Answer 1

只需创建一个 array .

var Kahoot = require('kahoot.js-updated');
var name = 'example';
var id = '12345';

var clients = new Array(3);
for (var i = 0; i < 3; i++) {
  var client = new Kahoot();
  client.join(id, name + (i + 1)).then(() => {
    client.on('question', question => {});
    client.on('questionStart', question => {
      question.answer(randomAnswer());
    });
  });
  clients[i] = client;
}

然后数组 clients 包含您的三个客户端。
