I've seen answers dealing with selecting elements in CSS and I'm wondering if it is possible to perform the following with one line using a wildcard in jQuery?

jQuery('.youtube-video-1')[0].contentWindow.postMessage('{"event":"command","func":"' + 'stopVideo' + '","args":""}', '*');
jQuery('.youtube-video-2')[0].contentWindow.postMessage('{"event":"command","func":"' + 'stopVideo' + '","args":""}', '*');
jQuery('.youtube-video-3')[0].contentWindow.postMessage('{"event":"command","func":"' + 'stopVideo' + '","args":""}', '*');

I've tried:

jQuery('.youtube-video-\\S*')[0].contentWindow.postMessage('{"event":"command","func":"' + 'stopVideo' + '","args":""}', '*');
jQuery('[class^=youtube-video-]')[0].contentWindow.postMessage('{"event":"command","func":"' + 'stopVideo' + '","args":""}', '*');

    this covers how to strcture your selector, however your handling of working with a collection rather than one element is also incorrect. [0] will always reduce the collection to 1 element, not all of them. Commented Mar 24, 2023 at 14:41

    Why not just add a youtube-video class to all of elements instead? Commented Mar 24, 2023 at 14:41
  • @KevinB [0] is used here to get to the DOM element of the SINGLE iframe with class="youtube-video-1" so Heretic Monkey's suggestion is better and even better to not use jQuery here at all. document.querySelectorAll('youtube-video-class').forEach(vidFrame => vidFrame.contentWindow.postMessage(.....))

    @mplungjan of course, though, using a single classname doesn't affect the [0] problem. In both cases that has to be resolved as well. Commented Mar 24, 2023 at 14:45
