尝试将jquery加载到tampermonkey脚本中 [英] Trying to load jquery into tampermonkey script

问题描述

我正在编写一个脚本，该脚本在加载登录页面时登录到我的大学网络.

I am writing a script which logs into my college network when the login page is loaded.

代码如下

// ==UserScript==
// @name       My Fancy New Userscript
// @namespace  http://use.i.E.your.homepage/
// @version    0.1
// @description  enter something useful
// @match      <College login page>
// @copyright  2012+, You
// ==/UserScript==    
$(document).ready(function() {

    var usr=document.getElementsByName("username");

    var pass = document.getElementByName("password");

    usr.value="usrname";    
    pass.value="password";    

    var submitButton = document.querySelector ('input[type="submit"][value="Login"]');

    var clickEvent  = document.createEvent ('MouseEvents');

    clickEvent.initEvent ('click', true, true);

    submitButton.dispatchEvent (clickEvent);

    });

控制台显示错误信息

$ is not defined

有人可以告诉我这是怎么回事吗?

Can someone tell me what is going on here?

推荐答案

您需要在用户脚本标头中包含@require才能加载jQuery.像这样:

You need to have a @require in the user script header to load jQuery. Something like:

// @require http://code.jquery.com/jquery-3.4.1.min.js

(从可用的jQuery版本列表中选择所需的版本)
