+    // If the document isn't being actively used, it may be appropriate to reload:
+    if (!document.hasFocus()) {
+      location.reload();
+      // Reloading will close the database, and also reload with the new JavaScript
+      // and database definitions.
+    } else {
+      // Alternatively you may close the database and display a message to the
+      // user. You need to ensure this isn't a disruptive user experience.
+      db.close();

I'll make a reference to the onclose event.
