Using Grease/tampermonkey, How Can I Have The Currently Viewed Definition At Dictionary.com Open At Thesaurus.com?

Using Greasemonkey or Tampermonkey, how can I have the currently viewed definition at Dictionary.com open at Thesaurus.com (and vice versa) when the links circled in red are clicke

Solution 1:

The follow code was able to fully achieve all goals outlined in my question:

// ==UserScript==
// @name         Restore links behavior at Thesaurus.com
// @namespace    http://tampermonkey.net/
// @version      0.1
// @description  try to take over the world!
// @author       You
// @match        *://www.thesaurus.com/*
// @match        *://www.dictionary.com/*
// @run-at       document-end
// @grant        none
// ==/UserScript==

(function() {
    'use strict';

    document.querySelectorAll('[data-linkid]').forEach(el => el.removeAttribute('data-linkid'));

    document.addEventListener('click', function(e) {
        var link = e.target.closest('a');
        //var link = e.target.closest('#content a'); // limit to the #content area
        var path = window.location.pathname; // /browse/myword

        if (link && link.getAttribute('href') != '#') {
            e.stopPropagation();
        }

        if (link && link.getAttribute('href') == 'http://www.thesaurus.com/') {
            link.setAttribute('href', 'http://www.thesaurus.com' + path);
        }
        else if (link && link.getAttribute('href') == 'http://www.dictionary.com/') {
            link.setAttribute('href', 'http://www.dictionary.com' + path);
        }
    }, true);

})();
