Including jQuery in the JavaScript Console

Including jQuery in the JavaScript console can be beneficial for websites that lack its integration. This allows developers to harness jQuery's capabilities, such as retrieving the number of rows in a table, even on websites that don't natively support jQuery.

To include jQuery in the JavaScript console, simply follow these steps:

1. Open your browser's JavaScript console.
2. Paste the following code into the console:

var jq = document.createElement('script');
jq.src = "https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js";
document.getElementsByTagName('head')[0].appendChild(jq);

This script creates a new script element, assigns it the jQuery CDN URL, and appends it to the document's head. By allowing time for the script to load, jQuery becomes available for use.

Note: If the website uses scripts that conflict with jQuery, you may encounter issues.

Update: To enhance convenience, you can create a bookmark with the following code as its URL:

javascript: (function(e, s) {
    e.src = s;
    e.onload = function() {
        jQuery.noConflict();
        console.log('jQuery injected');
    };
    document.head.appendChild(e);
})(document.createElement('script'), '//code.jquery.com/jquery-latest.min.js')

This bookmarklet will inject jQuery into the current webpage when clicked. Replace the CDN URL with your preferred version if necessary.
