<title>Service Worker: 3P iframe for partitioned service workers</title>
<script src="./test-helpers.sub.js"></script>
<script src="/common/get-host-info.sub.js"></script>
<script src="./partitioned-utils.js"></script>
<body>
This iframe will register a service worker when it loads and then add its own
iframe that will attempt to navigate to a url that service worker will intercept
and use to resolve the service worker's internal Promise.
<script>
async function onLoad() {
await setupServiceWorker();
// When the SW's iframe finishes it'll post a message. This forwards it up to
// the window.
self.addEventListener('message', evt => {
window.parent.postMessage(evt.data, '*');
});
// Now try to resolve the SW's promise. If we're partitioned then there
// shouldn't be a promise to resolve.
const resolve_frame_url = new URL('./partitioned-resolve.fakehtml?From3pFrame', self.location);
const frame_resolve = await new Promise(resolve => {
var frame = document.createElement('iframe');
frame.src = resolve_frame_url;
frame.onload = function() { resolve(frame); };
document.body.appendChild(frame);
});
}
self.addEventListener('load', onLoad);
</script>
</body>
