  • Once all registered callbacks are performed, the injector will be cleared.
  • Such feature currently we require the browser supporting WeakRef.
  • We offer both asynchronous and synchorized callback in customYtElements.whenRegistered, however, since _initializeProperties() and all other related layouting and rendering will be conducted immediately after component registration, synchorized callback is preferred.

Example 1:

// ==UserScript==
// @name         Testing
// @namespace    http://tampermonkey.net/
// @version      0.1
// @description  try to take over the world!
// @author       You
// @match        https://www.youtube.com/*
// @icon         https://www.google.com/s2/favicons?sz=64&domain=youtube.com
// @grant        none
// @run-at       document-start
// @require      https://greatest.deepsurf.us/scripts/465819-api-for-customelements-in-youtube/code/API%20for%20CustomElements%20in%20YouTube.js?version=1187694
// ==/UserScript==

(function () {
  'use strict';

  console.log('script started');
  customYtElements.whenRegistered('ytd-rich-grid-renderer', (proto) => {
    console.log('yt element is registered', proto.is);
    proto.calcElementsPerRow = () => 5;
  });

})();

Example 2

  • You might also check whether the injector function is garbage collected (GC) or not.

(function () {
  'use strict';

  console.log('script started');
  customYtElements.whenRegistered('ytd-rich-grid-renderer', (proto) => {
    console.log('yt element is registered', proto.is);
    proto.calcElementsPerRow = () => 5;
    if (typeof WeakRef === 'function') {
      console.debug('Is injector is cleared in memory? (#1)', proto._registered.__injector__.deref() === undefined);
      setTimeout(() => {
        console.debug('Is injector is cleared in memory? (#2)', proto._registered.__injector__.deref() === undefined);
      }, 5000);
    }
  });

})();
