Recently, while setting up the logging service for QRZ.com, I found that some button clicks were not responding. After opening the browser's developer tools, I discovered that the jQuery resource was being loaded from Google's CDN, but due to restrictions, it failed to load, which prevented the events on the webpage from firing.

Then, I came up with a lazy way: I introduced jQuery into the page by opening the developer tools console and creating a script tag to access a jQuery CDN resource.

var js = document.createElement('script');
js.type='text/javascript';
js.src='https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js';
document.head.appendChild(js);
Okay, then.
However, after switching pages, you need to re-execute it.
