+<p>{{domxref("ServiceWorkerContainer")}} 接口的 <strong><code>register()<font face="Open Sans, Arial, sans-serif"> </font></code></strong>方法创建或更新一个给定scriptURL的<code><a href="https://developer.mozilla.org/en-US/docs/Web/API/ServiceWorkerRegistration" title="The ServiceWorkerRegistion interface of the ServiceWorker API represents the service worker registration. You register a service worker to control one or more pages that share the same origin.">ServiceWorkerRegistration</a> </code>。</p>
+
+<p>如果成功，一个服务工作者注册将提供的脚本URL与一个范围进行关联，后者用于导航匹配。如果该方法无法返回一个 <code>ServiceWorkerRegistration</code>，则返回一个 <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise" title="The Promise object is used for deferred and asynchronous computations. A Promise is in one of the three states:"><code>Promise</code></a>。</p>
+
+<p>您可以从受控页无条件调用此方法, 即, 您不需要首先检查是否有一个有效的注册。</p>
