Trying to load jquery into tampermonkey script

问题

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

The code looks as follows

// ==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);

    });

The console shows a error saying

$ is not defined

Can someone tell me what is going on here?

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

(Selecting your desired version from the of list of available versions of jQuery)
