<p>It’s fun to think of <mark>other possible uses…</mark> Perhaps you could pull in HTML modules along with their relevant CSS link. Or embed a tweet or code examples in documentation or a blog post. It could probably even be used to load and apply a regular <code>rel=stylesheet</code> link asynchronously, and at a low priority, which is otherwise surprisingly hard to do (note: I didn’t test this idea much to say for&nbsp;sure).</p>

<p>J’ai cette page ouverte dans un onglet depuis littéralement des années. C’est <a data-link-domain="blog.notmyidea.org" href="https://blog.notmyidea.org/">Alexis</a> qui me l’a rappelé en partageant <a data-link-domain="leanrada.com" href="https://leanrada.com/htmz/">htmz</a> aujourd’hui qui va un tout petit peu plus&nbsp;loin.</p>
<p>Voilà le code en&nbsp;question&nbsp;:</p>
<pre><code>&lt;iframe 
  src=&quot;/static/david/2024/test-injection.html&quot; 
  onload=&quot;
    this.before(
      (
        this.contentDocument.body||this.contentDocument
      ).children[0]
    );
    this.remove()
  &quot; 
  hidden&gt;
&lt;/iframe&gt;
</code></pre>
<p>En résumé, on prend le code l’<code>iframe</code> et on l’injecte au chargement dans le document en cours. Voici un exemple (pas sûr que ça fonctionne depuis un&nbsp;agrégateur…)&nbsp;:</p>
<iframe src="/static/david/2024/test-injection.html" onload="this.before((this.contentDocument.body||this.contentDocument).children[0]);this.remove()" hidden></iframe>

<p>J’ai ajouté l’attribut <code>hidden</code> à la proposition initiale pour éviter le flash. Si vous inspectez le code, vous constatez que le paragraphe précédent tout à fait classique alors qu’il s’agissait d’une <code>iframe</code> (sauf si vous avez une extension qui bloque les <code>iframe</code> bien sûr). Jusque là c’est <a data-link-domain="css-tricks.com" href="https://css-tricks.com/the-simplest-ways-to-handle-html-includes/" hreflang="en"

                </svg>
                <span class="sr-only">[archive]</span></a> mais rien de bien&nbsp;utile.</p>
<p>Ce qui devient un peu plus fou serait de pouvoir injecter un <em>Web Component</em> de cette façon&#8239;! Le problème étant que le <code>this.remove()</code> est exécuté avant le chargement du script de l’<code>iframe</code>… et si on le retire on conserve cet élément <code>hidden</code> dans le document. Ce n’est pas critique mais ce n’est pas très élégant non plus, d’autant que cela signifie que le composant est défini et instancié deux&nbsp;fois.</p>

<iframe src="/static/david/2024/test-injection-web-component.html" onload= "this.before((this.contentDocument.body||this.contentDocument).children[0]);this.before(this.contentDocument.scripts[0])" hidden></iframe>

<p>So, what’s the fun of writing on the internet anymore? Well, if your aim is to be respected as an author, there’s probably not much fun to be had here at all. Don’t write online for fame and glory. Oblivion, obscurity and exploitation are all but guaranteed. Write here because <em>ideas</em> matter, not authorship. Write here because the more robots, pirates, and single-minded trolls swallow up cyberspace, <mark>the more we need independent writing in order to think new thoughts in the future</mark> — even if your words are getting dished up and plated by an&nbsp;algorithm.</p>
