fbIntegrationJS.setUiAdapter(tabletAdapter);
tabletAdapter defines
3 callback functions that are invoked by
FBintegrationCommon.js.
When a shopper accesses a product page, the
FBintegrationCommon.js script
is invoked by the Facebook SDK to respond to Facebook events. The
script also handles
Connect to Facebook and
Disconnect
from Facebook events from the link on the footer of the
page. The methods in
FBTAbletAdapter are then invoked
to accordingly update the store UI. In this case, the
_updateFacebookPlugins function
will refresh the
Like button;
_displayConnectFacebookLink will
display the
Connect to Facebook link at the
footer, while the
_displayFacebookMenu function
displays
Disconnect from Facebook.
