[英]First time using node.js - “ReferenceError: node is not defined”
[英]Using JQuery with Node.js “ReferenceError: $ is not defined”
我正在尝试使用此框架https://github.com/Schmoopiie/twitch-irc为Node.js中的Twitch构建一个简单的IRC机器人,该机器人可以连接到API并检查某些内容,在此参考资料中,我将检查该机器人所在的当前频道上的关注者。除了遇到错误外,我一直在下面记录此错误。

这是我用来运行的代码,以检查API
var irc = require('twitch-irc');
var colors = require('colors');
var jQuery = require('jQuery')
var jsdom = require("jsdom");
var window = jsdom.jsdom().parentWindow;
jsdom.jQueryify(window, "http://code.jquery.com/jquery-2.1.3.min.js", function () {
var $ = window.$;
$("body").prepend("<h1>The title</h1>");
console.log($("h1").html());
});
// Calling a new client..
var client = new irc.client({
options: {
debug: true,
debugIgnore: ['ping', 'chat', 'action'],
logging: true,
tc: 3
},
identity: {
username: 'BotName',
password: 'oauth:Code'
},
channels: ['#my', '#first', '#connect', '#channels']
});
// Connect the client to server..
client.connect();
client.addListener('chat', function(channel, user, message) {
if (message.indexOf('!followers') === 0) {
var channels = channel
channels = channels.replace('#', '');
$.getJSON('https://api.twitch.tv/kraken/channels/' + channels + '.json?callback=?', function(data) {
var followers = data.followers
client.say(channel, "Current Followers: " + followers);
console.log("Followers for " + channel + " " + followers);
});
}
});
我一直在尝试使这个refferenceerror消失数小时,但是我对在浏览器环境之外使用JS和JQ来产生任何结果还不够熟悉,因此,不胜感激。
Juhana Jan在对原始问题的评论中提供了正确答案:
当您说var jQuery = require('jQuery')时,您是将jQuery分配给名为jQuery的变量。 如果要使用$,则必须执行var $ = require('jQuery')。 – Juhana Jan
