<p>Obtient le titre de l'action du navigateur.</p>
<p>Tout comme vous pouvez définir le titre par onglet en utilisant {{WebExtAPIRef("browserAction.setTitle()")}}, vous pouvez donc récupérer un titre spécifique à un onglet en passant l'ID de l'onglet dans cette fonction.</p>
<p>Il s'agit d'une fonction asynchrone qui renvoie une <code><a href="/fr/docs/Web/JavaScript/Reference/Objets_globaux/Promise">Promise</a></code>.</p>
<h2 id="Syntaxe">Syntaxe</h2>
<pre class="syntaxbox brush:js">var gettingTitle = browser.browserAction.getTitle(
details // object
)
</pre>
<h3 id="Paramètres">Paramètres</h3>

<dd><code>object</code>.</dd>
<dd>
<dl class="reference-values">
<dt><code>tabId</code>{{optional_inline}}</dt>
<dd><code>integer</code>. Spécifiez l'onglet pour obtenir le titre.</dd>
<dt><code>windowId</code>{{optional_inline}}</dt>
<dd><code>integer</code>. Spécifiez la fenêtre à partir de laquelle vous souhaitez obtenir le titre.</dd>
</dl>
</dd>
</dl>
<ul>
<li>Si <code>windowId</code> et <code>tabId</code> sont tous deux fournis, la fonction échoue et la promesse qu'elle renvoie est rejetée.</li>
<li>Si <code>windowId</code> et <code>tabId</code> sont tous les deux omis, le titre global est renvoyé.</li>
</ul>
<h3 id="Return_value">Return value</h3>
